D. The reaction absorbs energy from its surroundings
Heat is a form of energy, so if the chemical reaction makes its surroundings become colder, it is absorbing heat energy.
CO2 can enter through many ways such as
1) Coal emissions from factories
2) The decomposition of living organisms
3) The breathing out of animals
4) Waste and animal waste
Hope this helps you
The Sample Size formula, also known as the Cochran Formula, allows for calculation of an ideal sample size. Below, I have inserted a picture of the formula, where it’s variables are as follows,
N=population size
E= margin of error
Z=z-score

Most mammals use the X and Y system to determine sex.
Males have 1 X chromosome and 1 Y chromosome while females have 2 X chromosomes.
The question states that there are 2 different sex chromosomes, so this rabbit must be male.

Dog breeding would be an example of artificial selection. That is, is follows the same processes in selecting for certain mutations as natural selection but is guided and directed by humans. The primary difference is that artificial selection is much faster as it can be directed and focused with intelligent guidance rather than blind direction from natural evolution.</span>
