Answer:
option (a) because....,
Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). ... Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA)
option (b) not because,
Within that centrosome there are two centrioles. And centrioles are physical objects made up of things called microtubules.
option (c) not because....,
Centromere repeats in humans are made up of alpha-satellite DNA, a ∼171 bp sequence or monomer that is iteratively repeated. Alpha-satellite monomers are arranged head-to-tail and organized into repeated arrays called higher order repeats (HORs) that range from 0.2 to 5 megabases (Mb) and are chromosome specific.

Since both aerobic and anaerobic processes can result in the production of CO2, we couldn't be certain that cellular respiration was occurring.
Carbon dioxide:
Carbon dioxide is released during cellular respiration as a waste product. Cells that are capable of photosynthesis can utilize this carbon dioxide to create new carbohydrates. Additionally, oxygen gas is necessary to act as an electron acceptor during the process of cellular respiration.
There are two types of cellular respiration: aerobic (occurring when oxygen is present) and anaerobic (in absence of oxygen).
Now, carbon dioxide is emitted as a byproduct in both types of respiration.
Therefore, determining the rate of aerobic cellular respiration by measuring the amount of carbon dioxide emitted is impossible.
Therefore, to obtain the precise rate, we monitor oxygen rather than carbon dioxide.
Therefore, the correct response is that CO2 is created during both aerobic and anaerobic processes; we were unable to confirm if cellular respiration was occurring.

B) They maintain balance in the cell.
That mix of hydrophobic and hydrophilic, in other words, the mix of repelling and attraction maintains the aqueous balance in a cell and it's exterior.

Scientists collect information that allows them to make evolutionary connections between organisms. Similar to detective work, scientists must use evidence to uncover the facts. In the case of phylogeny, evolutionary investigations focus on two types of evidence: morphologic (form and function) and genetic.
