Answer:
The correct statement would be - the bacterial cell due to the largest surface-to-volume ratio.
Explanation:
The surface area to volume ratio plays a very important role in determining the rate of the diffusion enter and exit from the cell body. If the surface-to-volume ratio is lower then the rate of diffusion would be lower to similarly with an increase in the ratio, the rate of diffusion also increases.
So, the bacteria like small organism have a cell which is exposed to a large surface area to the surrounding in comparison of the human egg cell.
Thus, the correct answer would be - the bacterial cell due to the largest surface-to-volume ratio.
A smaller spherical bacterial cell with a radius of 3μm can more efficiently exchange materials with the external environment compared to a larger human egg cell with a radius of 100μm, due to its higher surface area-to-volume ratio.
The statement that correctly indicates the cell that is able to more efficiently exchange materials with the external environment is that the spherical bacterial cell with a radius of 3μm can more efficiently exchange materials. This is because a smaller cell has a higher surface area-to-volume ratio, allowing for a faster exchange of materials through the cell membrane. On the other hand, the human egg cell with a radius of 100μm, being larger, has a lower surface area-to-volume ratio and is less efficient in exchanging materials with the external environment.

B.Meiosis produces recombinant chromosomes.
C.Meiosis begins with a diploid cell, but produces four haploid cells.
The statement 'Meiosis begins with a diploid cell and produces four haploid cells' justifies meiosis as a reduction division due to the transition from a cell with two sets of chromosomes to cells with a single set.
The statement that justifies meiosis as a reduction division is: 'Meiosis begins with a diploid cell and produces four haploid cells'. This statement acknowledges the reductional nature of meiosis: it essentially begins with a cell that contains two sets of chromosomes (diploid), and through a specific series of cell division stages, it results in four cells that each have a single set of chromosomes (haploid). While it's true that meiosis results in the formation of gametes and leads to recombinant chromosomes, the primary defining characteristic of meiosis as a reduction division is its transition from a diploid cell to haploid cells.

Answer:
Green house gases are the type of gases present in the air which have the ability to trap heat of the earth's surface. Gases like carbon dioxide and methane are found naturally and are known to play an important role in earth's climate. If they are not found the earth' s climate would be too cold creating problem for survival of life on the earth.
These green house gases absorb the emit the radiation in the thermal infrared range. These gases act like a blanket and save earth surface from infrared radiation by absorbing them and prevent them from escaping out of the earth surface.
But now a days due to increased in the concentration of green house gases like carbon dioxide and methane due to pollution and deforestation causing a great problem called as green house effect which lead to global warming and it a great concern for all the people now a days.
Greenhouse gases refer to the gases, which are crucial to maintaining a suitable temperature for life on Earth. Examples are methane, carbon dioxide, and nitrous oxide.
Greenhouse gases such as water vapor, methane, fluorinated gases, and carbon dioxide trap the sunlight and raise the temperature of the Earth keeping it warm.
The gases are a concern for the environment and life on earth as in the absence of these gases, the Earth's climate will be extremely cold and chilly.
These gases act as a protective blanket, saving them from infrared rays and other harmful rays. Also, the increased emission of these gases is leading to global warming, which is one of the major threats to life on Earth.
Thus, greenhouse gases are essential but their increased emission is a major concern for the planet.
