The taxonomic category between kingdom and class is Phylum.
Answer:
Enzyme-linked
Explanation:
The cell surface receptors that have intracellular domains associated with enzymes are called enzyme-linked receptors. The added molecule was water-soluble and cannot pass through the membrane to bind to intracellular receptors. Binding of the added molecule to the enzyme-linked receptor led to the activation of associated enzymes to generate the response (down-regulation of expression of the target gene).
Examples of enzyme-linked receptors include tyrosine kinase receptors. Binding of the signaling molecule to these receptors triggers phosphorylation of the intracellular domain which in turn transmits the signal to the cytoplasmic messenger.
Answer:
B competition will increase
Explanation:
this is because if there are less acorns then squirrels then they will all fight for the acorns and some will die to starvation. nest size won't increase because there isn't enough food for the squirrels already there. predation will decrease because there is less squirrels so that means less pray for the animals that eat the squirrels. then there is reproduction rates will increase. It is not that one because there are squirrels dying from starvation there aren't squirrels reproducing. that is why your answer is B.
