A decrease in plant life would cause carbon dioxide levels to increase and oxygen levels to decrease. Therefore option B is correct.
Plants play a crucial role in the biosphere by performing photosynthesis, a process that absorbs carbon dioxide (CO2) from the atmosphere and releases oxygen (O2) as a byproduct.
With a decrease in plant life, the rate of photosynthesis would decrease, resulting in reduced CO2 absorption and lower oxygen production.
As a consequence, carbon dioxide levels would increase in the atmosphere, leading to potential implications for global warming and climate change.
Additionally, the decrease in oxygen production could have adverse effects on the air quality and the oxygen supply necessary for supporting aerobic life forms.
Thus, the reduction of plant life could disrupt the delicate balance of atmospheric gases, influencing the Earth's climate and living organisms.
Therefore option B A decrease in plant life would cause carbon dioxide levels to increase and oxygen levels to decrease. is correct.

Chromosomes have two chromatids at the end of meiosis I and one chromatid at the end of meiosis II. The correct option is D.
The division of gametic or sex cells is known as meiosis. The process of reproduction involves this. It takes eight phases to finish. It is split into two sections. The first and second meiosis.
When a cell is dividing, it is a haploid cell. One set of chromosomes makes up a haploid cell. It includes all of its chromosomes during meiosis. Chromosomes are hereditary material.
In the chromosomes in meiosis 1 a full set of chromosomes is present and in meiosis 2, the number is diploid (2N).
Therefore, the correct option is D,Chromosomes have two chromatids at the end of meiosis I and one chromatid at the end of meiosis II.

The question is incomplete. Your most probably complete question is given below:
Chromosomes have one chromatid at the end of both meiosis I and meiosis II
Chromosomes have two chromatids at the end of both meioses I and meiosis II.
Chromosomes have one chromatid at the end of meiosis I and two chromatids at the end of meiosis II.
Chromosomes have two chromatids at the end of meiosis I and one chromatid at the end of meiosis II.
Answer : The electrocardiogram records the electrical signals of heart.
Explanation :
Electrocardiogram : It is a type graph that records the electrical signals or rate of the heart. It is also called ECGs.
It is a common test that is used to detect the problems in heart and also monitor the status of the heart in many conditions.
During the ECG, sensors (electrodes) that can detect the electrical activity of the heart are attached to the chest.
Hence, the type of data recorded by the electrocardiogram is the electrical signals of heart.
An electrocardiogram records the electrical activity of the heart.

Answer is D) low-gravity.
Why? Because all outer planets are made up of gas, so C is not it, outer planets are way more bigger than inner planets, so A is not it, and Jupiter, Saturn, Uranus, and Neptune are outer planets, so B is not it. So D is the right answer!
Hope this helped!

The stigma's sticky exudate is complex blend of substances that trap the pollen and prepare the pollen grains to perform fertilization.
So what it means that the flower could it can trap pollen.The pistil develops ovules inside . The ovules after fertilization develop into the seeds . seeds are sexual means of reproduction
I hope that's help !
