I believe this question is trying to get you to realize the difference between acquired traits(one you get through doing something during life) and heritable traits(ones from Mom/Dad). For example, I really wish I was 6 foot 4... but the height trait comes genetically from your parents since it is coded in my DNA how tall I will be, therefore this trait must be passed down genetically and somewhere down the evolutionary tree the humans in the region which my family comes from was better off being short. An example that comes from acquired traits could be muscularity... my parents are both not very muscular but throughout my lifetime I enjoy working out and have become much more muscular, no matter how much your parents or grandparents lift weights YOU won't change so that change must be acquired through aging during your lifetime. Now the amount of muscle your body can put on is a heritable thing but that is beside the point. Hope this helps :)
With the equation of cellular respiration C₆H₁₂O₆ + 6O₂ → 6CO₂+ 6H₂O, gaseous exchange takes place, glucose reacts with oxygen forming Adenosine Triphosphate used by cells.
About 21% of oxygen and 0.4% of carbon dioxide of air is inhaled while the air we breathe out contains 16.4% of oxygen and 4.4% of carbon dioxide because cells use oxygen inhaled to release energy and carbon dioxide as byproduct.
<h3>How does Cellular Respiration work?</h3>
Cellular respiration is how organisms convert fuel into energy and nutrients by combining oxygen with food molecules, sending the chemical energy for life sustaining activities while expelling carbon dioxide and water.
We inhale 21% of oxygen and 0.4% of carbon dioxide and exhale 16.4% of oxygen and 4.4% of carbon dioxide as by product during the process of cellular respiration.

Mitosis - 48 chromosomes (diploid cells)
Meiosis - 24 chromosomes (haploid cells)
Diploid cells. Meiosis is the process of cell division by which involving gametes. Cell division is just the same for sperm and egg cells, but they have distinguishable descriptions and labels in the process. Spermatogenesis is for the males’ sperm cells and oogenesis is the process for females’ egg cells. The cell division of meiosis involves the two phases, respectively meiosis I and meiosis II. Meiosis I like mitosis is the cell division that produces diploid cells<span>. These diploid cells are cells that contain a complete pair of chromosomes which is 46. The result is two diploid cells after the first meiosis. To provide clear explanation, in contrast haploid cells only contain 23 chromosomes and are created after meiosis II which is 4 in number.</span>
A is the correct answer!
- water can moderate temperature v. well that's why it's used as a cooling agent
- water expands upon freezing (that's why ice floats on water!)
