b. Fast twitch, because they primarily use aerobic respiration
c. Fast twitch, because they primarily use lactic acid fermentation

Answer:

The correct answer will be option c.

Explanation:

Two types of skeletal muscles are used in exercise: fast twitch and slow twitch.

Slow-twitch muscles help in long-endurance exercises like marathon running as they have more mitochondria and use aerobic respiration to produce energy.

But fast-twitch especially types IIb muscle is used in the exercise which requires powerful bursts like weight-lifting and sprinting as fibres do not have the capability to store oxygen so begin producing energy by lactic acid fermentation.

Thus, option c is the correct answer.

Explanation:

Option A is correct because the reproduction of the cell implies arrangement of chromosomes, making of proteins, organelles, cytokinesis and other cells process that need energy since the mitochondria is not working properly there isn't an appropriate organelle function ( option B).

Option D is correct because ATP is needed for the membrane proteins to undergo active transport. For example the sodium-potassium pump is crucial for the balance of ions. With no energy the protein involved in this process would not work.

One of your fellow systematists has asked you to help her group organisms into a valid phylogenetic tree. At present, she has gr
kipiarov [429]

Answer and explanation:

Monophyletic species are the species whose lineage belongs to the common recent phylogenetic ancestor. As mentioned in the question, the girl has 3 species namely G, H, and K. Because there is no other criteria given, we assume that the closeness of alphabets would reflect the closeness of species. Thus, G and H are closer relative than K. Therefore, if she adds <u>I, and J species</u> in the list, all of them will be closer relatives and we can say that they are monophyletic now.
