Answer: C. 63

Explanation:
- Dmitri Mendeleev presented the first periodic table in 1869.
- He arranged the elements in order of increasing atomic mass and grouped them based on their similar properties.
- At that time, Mendeleev's periodic table consisted of 63 known elements.
- The elements were organized into horizontal rows called periods and vertical columns called groups.
- Each element was assigned a unique atomic number, symbol, and atomic mass.
- Mendeleev's periodic table provided a systematic way to organize and predict the properties of elements.
- Over time, the periodic table has expanded as new elements have been discovered or synthesized.
- Currently, there are 118 known elements in the modern periodic table.
- However, at the time Mendeleev presented his periodic table, only 63 elements were known.
In summary:
- The number of elements known in Mendeleev's presented periodic table is 63.." }}},{"@type": "Question","typicalAgeRange": "4-35","educationalLevel": "intermediate","eduQuestionType": "Multiple choice","learningResourceType": "Practice problem","name": "Recollect the concept of HTET TGT Science Mock Test - 6 to solve the ques", "comment": { "@type": "Comment", "text": "

Activity-based learning as the name suggests actively involves learners in the construction and re-construction of knowledge based on his or her individual experiences. The activity approach takes you a little more time to prepare than a lecture or a demonstration. But the activity approach will not add to your burden.

Important Points

The classroom seems creative as the teacher is giving opportunities to students to ask doubts and also to explore the answers which mean Rahul wants his students to be creative and think about the problem.
This would make them creative and help in developing a scientific attitude as well as scientific temper.
We cannot say that the teacher is engaged in the irrelevant activity or the students are passing time as these are the parts of the teaching-learning program.

Key Points

In the activity-based approach, we consider the following assumptions-

Pupils have different learning styles (that instruction should accommodate)
Children’s innate curiosity and self-perpetuating exploratory behavior should form the basis of their learning in school.
They should have the opportunity to pursue their interests as deeply and as long as they find the pursuit satisfying.
The individual child often learn in unpredictable ways (and instruction should accommodate such eventualities)
Children are capable of making intelligent decisions in significant areas of their own learning.
The function of the school is to help children develop learning to learn in order to become lifelong learners.
Children have adopted the skill of questioning by discussing among them.
Learning is facilitated by the relationship of openness, trust, and mutual respect; and school should provide an accepting and warm emotional climate.

Hence, we can conclude that the classroom activity is creative.

" }, "answerExplanation": { "@type": "Comment", "text": "

The correct option is B.
In first ionisation energy, we remove electron from a neutral atom but for second ionisation we have to remove electron from a positive atom, where electron are more tightly bounded due to increased attraction force so second ionisation energy is high relative to first IP.

" }, "answerExplanation": { "@type": "Comment", "text": "

The dispersion of light is the phenomenon of splitting of a beam of white light into its seven constituent colours when passed through a transparent medium. It was discovered by Isaac Newton in 1666. Newton discovered that light is made up of seven different colours. He passed a beam of sunlight through a glass prism. The glass prism split the light into a band of seven colours on his wall. He called this band of colours the ‘spectrum’. Thus the spectrum is a band of seven colours which is obtained by splitting of white light by a glass prism. The order of colours from the lower end of spectrum is violet (V), indigo (I), blue (B), green (G), yellow (Y), orange (O), and red (R). The sequence of the 7 colours so obtained in a spectrum can be remembered by using the acronym ‘VIBGYOR’.

Methods are ways of teaching. Effective learning of children depends on the method the teacher adopts. Vandana in interested to focus more on the acquisition of process skills of science by students of Class VIII. She should prefer Project - cum - laboratory method to teach the topic of 'Microorganisms'.

Key Points

Project - cum- Laboratory Method-

The project method of teaching is one of the modern methods of teaching in which the curriculum content is considered from a child's point of view and is related to his needs and interest in the context of real-life situations.
The laboratory method is one of the most widely used teacher-centric methods for teaching science. This method is being used to provide hands-on experience to every learner.
The laboratory method follows the principle of ‘learning by doing’ and it is a common saying that the best way ‘to learn science is to do science’.
In this method, learners are more active and doing experiments on their own but they are fully guided and instructed by their teachers.
laboratory method helps teachers in-
- motivating learners through stimulating their interest and increasing their enjoyment
- teaching laboratory skills
- assisting concept acquisition and development
- developing and understanding of scientific inquiry and developing expertise in conducting inquiries
- encouraging social skills development
- inculcating the scientific attitudes
Learners are asked to record the observation while doing the experiments.
Generally, learners test the hypotheses; they are framed during a discussion on any topic/problem. It is advised that you should ask learners to test their hypotheses one by one and record their observations.

Thus from the above-mentioned points, it is clear that Vandana should prefer to teach the topic on 'Microorganisms' by Project - cum - laboratory method.

Chloroplast and mitochondria are the only two organelles that contain their own genetic material.
Besides containing genetic material they also contain 70S type ribosome, own enzymes and some amount of RNA as well.
They can also undergo fission themselves and thus can multiply themselves.
This is why these two organelles are called semi-autonomous organelles.

A heavy cylinder of length 1 is slowly taken out of a dense liquid. The weight felt as it is taken out of the liquid

" }, "answerExplanation": { "@type": "Comment", "text": "
When the heavy cylinder is slowly taken out of a dense liquid, the weight felt by the cylinder will change. Here's a detailed explanation of why the weight increases till it attains the weight in air:
- Weight in liquid: When the cylinder is fully submerged in the dense liquid, it experiences a buoyant force equal to the weight of the liquid displaced by the cylinder. This buoyant force partially cancels out the weight of the cylinder, making it feel lighter than its actual weight in air. So, the weight felt in the liquid is less than the weight in air.
- Weight as it comes out: As the cylinder is slowly taken out of the liquid, the buoyant force acting on it decreases gradually. This is because the amount of liquid displaced by the cylinder decreases as it comes out of the liquid.
- Weight increase: Since the buoyant force decreases, the net force acting on the cylinder increases. According to Newton's second law of motion (F = ma), an increase in net force leads to an increase in acceleration. In this case, the acceleration is upwards, opposite to the direction of gravity. As a result, the weight felt by the cylinder increases as it comes out of the liquid.
- Weight in air: Once the cylinder is completely out of the liquid, there is no more buoyant force acting on it. At this point, the weight felt by the cylinder is equal to its weight in air.
In conclusion, the weight felt by the cylinder increases as it comes out of the dense liquid until it attains the weight in air. Therefore, the correct answer is option D: increases till it attains the weight in air.." }}},{"@type": "Question","typicalAgeRange": "4-35","educationalLevel": "intermediate","eduQuestionType": "Multiple choice","learningResourceType": "Practice problem","name": "Recollect the concept of HTET TGT Science Mock Test - 6 to solve the ques", "comment": { "@type": "Comment", "text": "

In case the ova does not fertilise, which of the following events will take place?

A.
Menstruation
B.
Pregnancy
C.
Implantation
D.
Ovulation

Detailed Solution for HTET TGT Science Mock Test - 6 - Question 113

Explanation:
If the ova (eggs) do not fertilize, the following events will take place:
1. Menstruation: Menstruation refers to the shedding of the uterine lining that occurs when fertilization does not occur. The unfertilized egg, along with the thickened uterine lining, is expelled from the body through the vagin* during menstruation.

2. Pregnancy: Since fertilization did not occur, there will be no pregnancy. Pregnancy occurs when a sperm fertilizes an egg, resulting in the implantation and development of an embryo in the uterus.
3. Implantation: Implantation is the process by which a fertilized egg attaches itself to the lining of the uterus. In the absence of fertilization, there will be no implantation.
4. Ovulation: Ovulation is the release of a mature egg from the ovary. If fertilization does not occur, ovulation will still take place in the next menstrual cycle, as it is a regular process in the female reproductive system.
Therefore, the correct answer is A: Menstruation.

Detailed Solution for HTET TGT Science Mock Test - 6 - Question 120

Effects of Ozone Depletion:
There are several effects of ozone depletion on Earth's environment and climate. These include:
1. Increased Ultraviolet (UV) Radiation:
- Ozone depletion leads to an increase in the amount of UV radiation reaching the Earth's surface.
- This is because ozone molecules in the stratosphere absorb and block a significant portion of the UV radiation from the sun.
- With the depletion of ozone, more UV radiation penetrates the atmosphere, leading to potential harmful effects on human health and ecosystems.
2. Negative Health Effects:
- Increased UV radiation can have detrimental effects on human health, such as an increased risk of skin cancer, cataracts, and weakened immune system.
- UV radiation can also damage marine life, including coral reefs, phytoplankton, and other aquatic organisms.
3. Impact on Ecosystems:
- Ozone depletion can have severe consequences for ecosystems and biodiversity.
- UV radiation can inhibit photosynthesis and reduce plant growth, affecting the entire food chain.
- It can also harm plankton, which are vital for marine ecosystems and serve as a primary food source for many marine organisms.
4. Climate Change:
- While ozone depletion itself does not directly cause global warming, it can indirectly contribute to climate change.
- Ozone depletion affects atmospheric circulation patterns, leading to changes in wind patterns, temperature distribution, and precipitation.
- These changes in climate patterns can have subsequent impacts on weather systems and regional climates.
In conclusion, ozone depletion primarily results in an increase in UV radiation reaching the Earth's surface, which has negative consequences for human health, ecosystems, and climate.

B. The teacher is teaching irrelevant topics.
C. Useless doubt is disrupting classroom activities.
D. Students have got opportunities to pass time.

Detailed Solution for HTET TGT Science Mock Test - 6 - Question 131

Important Points

The classroom seems creative as the teacher is giving opportunities to students to ask doubts and also to explore the answers which mean Rahul wants his students to be creative and think about the problem.
This would make them creative and help in developing a scientific attitude as well as scientific temper.
We cannot say that the teacher is engaged in the irrelevant activity or the students are passing time as these are the parts of the teaching-learning program.

Key Points

In the activity-based approach, we consider the following assumptions-

Pupils have different learning styles (that instruction should accommodate)
Children’s innate curiosity and self-perpetuating exploratory behavior should form the basis of their learning in school.
They should have the opportunity to pursue their interests as deeply and as long as they find the pursuit satisfying.
The individual child often learn in unpredictable ways (and instruction should accommodate such eventualities)
Children are capable of making intelligent decisions in significant areas of their own learning.
The function of the school is to help children develop learning to learn in order to become lifelong learners.
Children have adopted the skill of questioning by discussing among them.
Learning is facilitated by the relationship of openness, trust, and mutual respect; and school should provide an accepting and warm emotional climate.

Hence, we can conclude that the classroom activity is creative.

Key Points

Project - cum- Laboratory Method-

The project method of teaching is one of the modern methods of teaching in which the curriculum content is considered from a child's point of view and is related to his needs and interest in the context of real-life situations.
The laboratory method is one of the most widely used teacher-centric methods for teaching science. This method is being used to provide hands-on experience to every learner.
The laboratory method follows the principle of ‘learning by doing’ and it is a common saying that the best way ‘to learn science is to do science’.
In this method, learners are more active and doing experiments on their own but they are fully guided and instructed by their teachers.
laboratory method helps teachers in-
- motivating learners through stimulating their interest and increasing their enjoyment
- teaching laboratory skills
- assisting concept acquisition and development
- developing and understanding of scientific inquiry and developing expertise in conducting inquiries
- encouraging social skills development
- inculcating the scientific attitudes
Learners are asked to record the observation while doing the experiments.
Generally, learners test the hypotheses; they are framed during a discussion on any topic/problem. It is advised that you should ask learners to test their hypotheses one by one and record their observations.

Thus from the above-mentioned points, it is clear that Vandana should prefer to teach the topic on 'Microorganisms' by Project - cum - laboratory method.

A heavy cylinder of length 1 is slowly taken out of a dense liquid. The weight felt as it is taken out of the liquid

A.
will remain the same
B.
increases as it comes out
C.
decreases as it comes out
D.
increases till it attains the weight in air

Detailed Solution for HTET TGT Science Mock Test - 6 - Question 144

When the heavy cylinder is slowly taken out of a dense liquid, the weight felt by the cylinder will change. Here's a detailed explanation of why the weight increases till it attains the weight in air:
- Weight in liquid: When the cylinder is fully submerged in the dense liquid, it experiences a buoyant force equal to the weight of the liquid displaced by the cylinder. This buoyant force partially cancels out the weight of the cylinder, making it feel lighter than its actual weight in air. So, the weight felt in the liquid is less than the weight in air.
- Weight as it comes out: As the cylinder is slowly taken out of the liquid, the buoyant force acting on it decreases gradually. This is because the amount of liquid displaced by the cylinder decreases as it comes out of the liquid.
- Weight increase: Since the buoyant force decreases, the net force acting on the cylinder increases. According to Newton's second law of motion (F = ma), an increase in net force leads to an increase in acceleration. In this case, the acceleration is upwards, opposite to the direction of gravity. As a result, the weight felt by the cylinder increases as it comes out of the liquid.
- Weight in air: Once the cylinder is completely out of the liquid, there is no more buoyant force acting on it. At this point, the weight felt by the cylinder is equal to its weight in air.
In conclusion, the weight felt by the cylinder increases as it comes out of the dense liquid until it attains the weight in air. Therefore, the correct answer is option D: increases till it attains the weight in air.
