Answer:
Diffrence:
Asexual reproduction involves one parent and produces offspring that are genetically identical to each other and to the parent. parent. During sexual reproduction, two haploid gametes join in the process of fertilization to produce a diploid zygote. Meiosis is the type of cell division that produces gametes.
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.

A variety of genes are involved in the control of cell growth and division. The cell cycle is the cell's way of replicating itself in an organized, step-by-step fashion. ... Cancer results from a disruption of the normal regulation of the cell cycle.
Answer: are translucent (permit light to pass through them)
Explanation:
Phase-contrast microscopy is especially useful for detecting bacterial structures like endospores and inclusions because these structures are translucent.
Objects viewed under a phase-constrast microscope appear with a opposite colour, and do not require stain or dye to be viewed
