Answer:
D. A deer has flat teeth for chewing plants.
Explanation:
Adaptation, which is the ability of an organism to survive changes in its natural environment, can either be structural, behavioral and physiological. Structural adaptation is the possession of a physical or structural feature by an organism to enable it survive or adjust to change.
According to this question, the FLAT TEETH possessed by the deer for chewing plants is an example of structural adaptation because the deer posseses a structural feature (flat teeth) that allows it to feed on plants for survival.
The cellular response to the second messenger is a mutation that affects ca++ binding to calmodulin and is most likely to interfere with what aspect of a signal transduction pathway.
<h3>Ca++ binding to calmodulin :</h3>
This protein-protein interaction ultimately has a physiological consequence; for instance, in smooth muscle, Ca2+ binding to calmodulin causes it to connect with and activate myosin light chain kinase, which in turn catalyzes the phosphorylation of myosin. The smooth muscle contracts as a result of this reaction.
A common, tiny (148 amino acids) calcium signaling protein called calmodulin (CaM) controls the actions of numerous cellular proteins. It has two calcium-binding sites in the N-domain (I and II) and two more in the C-domain (III and IV).
In order for smooth muscle to contract, calmodulin is crucial for excitation-contraction (EC) coupling and the start of the cross-bridge cycling in smooth muscle. The head of the myosin light chain must be phosphorylated to initiate smooth muscle contraction.

Mach what item?. Isn't there suppose to be answers to go with it? :/
Answer:
brothers and sisters don't look exactly alike because everyone (including parents) actually has two copies of most of their genes. And these copies can be different. Parents pass one of their two copies of each of their genes to their kids.
