The response options in this group are typically noncovalently linked to the membrane lipids that compose peripheral membrane proteins.
What is Peripheral membrane proteins ?Extrinsic membrane proteins, also known as peripheral membrane proteins, are membrane proteins that are connected with biological membranes but only briefly bind to those membranes. These proteins either bind to integral membrane proteins or pierce the lipid bilayer in the periphery.
Directing and maintaining the internal cytoskeleton and elements of the extracellular matrix are two of the primary functions of peripheral proteins. Organelles, filaments, and tubules work together to create both of these structures.
Proteins that only associate with the membrane through electrostatic or hydrophobic interactions (Caldalkalibacillus thermarum type-II NADH dehydrogenase as an example) and proteins that anchor themselves in the lipid bilayer using a hydrophobic segment are two subtypes of peripheral membrane proteins.
What is lipid bilayer ? A thin polar membrane comprised of two layers of lipid molecules is known as a lipid bilayer. These membranes are flat sheets that surround every cell in a continuous barrier.The lipid bilayer serves as a barrier, retaining ions, proteins, and other molecules where they are required while preventing their diffusion into unintended locations.The creation of membrane microdomains that are helpful for biological processes depends on how a lipid bilayer moves between its two primary phases, the liquid crystalline phase (L) and the gel phase (L), during a transition.To know more about Peripheral membrane proteins please click here ;

Insulin binding ultimately increases pancreatic secretion of additional insulin.
Insulin binding to the insulin receptor on osteoblasts stimulates a signalling pathway, causing the release of the chemical OPG by the osteoblasts, which then binds to the nearby osteoclasts. The osteoclasts react by releasing protons (H+), which lowers the pH outside the cell. Osteocalcin, a protein released by osteoblasts in an inactive state, is activated by this low pH.

the physical symptoms of cholera present only after a specific series of events has taken place. what is the most likely sequence of events in the pathogenesis of v. cholera
Cholera spreads via the fecal-oral pathway. The most likely progression of events in the pathogenesis of V. cholera:
The oral-fecal route is how cholera is spread. Since they are susceptible to acid, most vibrio's pass away in the stomach. Virulent organisms that survive may stick to and colonize the small intestine, where they release the strong cholera enterotoxin (CT, also known as "choleragen") that causes cholera. This toxin attaches to the intestinal epithelial cells' plasma membrane and releases an enzyme-active component that increases the generation of cyclic adenosine 51-monophosphate (cAMP). Electrolytes and water are secreted in large quantities into the intestinal lumen as a result of the elevated intracellular cAMP level and cause diarrhea.
1 V. cholerae is ingested via contaminated water.
2 V. cholerae reaches the intestine after surviving transit through the stomach.
3 Cholerae cling to pili.

The best can be explained as "the increase in action potential conduction velocity due to myelination" is a decrease in membrane capacitance.
What happened if the resistance of the membrane is increased?If the resistаnce of the membrаne is increаsed, more of the depolаrizing current pаsses down the аxon аnd dischаrges the cаpаcitor on the membrаne. Thus insulаting the membrаne with myelin increаses the pаssive spreаd of current аnd increаses conduction velocity. Decreаsing the membrаne cаpаcitаnce аlso increаses conduction velocity. Аdding myelin increаses the thickness of the membrаne cаpаcitor, which decreаses its cаpаcitаnce. Increаsing the diаmeter of the аxoplаsm decreаses the internаl resistаnce, which fаcilitаtes pаssive spreаd of current аnd increаses conduction velocity.

Answer:
my guess if I remember correctly I think the answer is b
At the end of DNA replication, there should be a total of B. 2 DOUBLE stranded DNA helices. During DNA replication, the DNA double helix unwinds, and each strand acts as a template for the synthesis of a new complementary strand.
DNA replication is a fundamental process in which a cell produces two identical copies of its DNA molecule. It occurs during the cell cycle's synthesis (S) phase, ensuring that each daughter cell receives a complete set of genetic information. The replication process begins with the unwinding of the DNA double helix. An enzyme called helicase unwinds and separates the two strands of the DNA molecule by breaking the hydrogen bonds between the base pairs.
