Alexandra [31]

The third and last option is correct.


Species in the past (referring to dinosaurs) were more massive.

\bf~CO_{2} levels where higher in the past, which meant that plants prospered during that time since they had a easy access to food. That contributes to the fact that herbivores could grow bigger because there was more food. Which in turn, increases the size of early carnivores which eat bigger herbivores.




Hope it helped,


Happy homework/ study/ exam!

The order in which the amino-acids are placed within the polypeptide determines the tertiary structure and therefore the function of the given protein. Amino acids have different functional groups like methyl(CH3), phenyl(C6H5). Those functional groups can interact with molecules like glucose determining reactions, the proteins that catalyze reactions are called enzymes. Other functional groups of amino acids can be the sulfate groups. For example, insulin has 2 polypeptide chains(Chain A has 21 amino acids, and chain B, 30). Between the two polypeptide chains, 2 disulfide bonds form altering its shape.

ction potentials typically move in one direction along the neuron away from the cell body. This is due to which of the following
aleksklad [387]

Answer:

The correct answer is option A. "the temporary hyperpolarization of the axon membrane following the action potential spike".

Explanation:

Action potentials, also known as "spikes" or "impulses", are electric impulses that neurons use to send information from the cell's body down to the axon. The impulses are created when ions travel across the neuron's membrane creating a depolarization current. This depolarization current is responsible for an temporary hyperpolarization of the axon membrane following the action potential spike. When neurons are hyperpolarized they are not able to produce another action potential. In consequence, actions potentials move in one direction along the neuron away from the cell body, as well as, adjacent locations go trough similar depolarization processes.
