The process of respiration system would not function well if the lungs was made up of only one big alveoli.
<u>Explanation:</u>
The main role of alveoli is to help the lungs to breath, for ventilation, diffusion and perfusion. The process of respiration system would not function well if the lungs was made up of only one big alveoli.
Alveoli are tiny to help the flow of oxygen and carbon dioxide, it helps the oxygen flow into the lungs and remove the carbon dioxide. If the alveoli is just one and big, then it would be hard to flow the oxygen through lungs and remove the carbon dioxide.
Therefore, it is good to have many tiny alveoli than one big one or the rib cage that protect the lungs could go through some damages.
Answer:
(D) Z
Explanation:
Cellular respiration is a catabolic process by which cells produce energy by oxidising respiratory substrates such as glucose. It is a multistage process occurs in cytoplasm and in mitochondria of a cell. The first stage of cellular respiration is called glycolysis or EMP (Embden, Meyerhof and Parnas) pathway. This stage occurs in the cytoplasm of a cell which is labeled by Z in the given image.
Answer: It is <u>the metabolic process in living organisms by which oxygen is combined with carbon in a cell to form carbon dioxide and generate energy.</u>

<span>The
interaction of motor proteins such as dynein, is responsible for the movement
of organelles in cells which uses energy to move parts of the cytoskeleton. Cytoskeleton is a network of intermediate
filaments, microtubules and microfilaments that outspread throughout the
cytoplasm and serve a variety of signaling, transport and mechanical functions.</span>
