Answer:
The correct answer is D
Explanation:
The cell membrane is essentially composed of the following:
- phospholipids
- cholesterol
- proteins
The phospholipid consists of a <em>hydrophilic </em>phosphate 'head' and the tail is the <em>hydrophobic</em> fatty acid chain.When cellular membranes form,phospholipids collect into two layers in light of these hydrophilic and hydrophobic properties. The phosphate heads in each layer face the fluid or watery condition on either side, and the tails conceal away from the water between the layers of heads, since they are hydrophobic.
There are 3 main factors that greatly influence the fluidity of the plasma membrane:
- temperature
- cholesterol
- saturated and unsaturated fatty acids

For an exothermic change: Notice that in an exothermic change, the </span>products<span> have a </span>lower energy than<span> the </span>reactants<span>.</span>
Answer:
The answer is B. The most recent common ancestor.
Explanation:
Cladograms are used to illustrate relationships related to morphological and evolutive traits. So then, in a cladogram when organisms are closely related, they appear closer in the branches. Common branches and nodes mean close relationships and common ancestors on a scale of time.
Answer:
There is no cure for herpes but medication can be taken to help it.
Explanation:
This is word for word from medlineplus. org
"Herpes is an infection that is caused by a herpes simplex virus (HSV). Oral herpes causes cold sores around the mouth or face. G*nital herpes affects the genitals, b*ttocks or an*l area. G*nital herpes is a s*xually transmitted disease (STD)."
CDC. gov says
"Herpes infection can cause sores or breaks in the skin or lining of the mouth, v*gina, and rectum. This provides a way for HIV to enter the body. Even without visible sores, having g*nital herpes increases the number of CD4 cells (the cells that HIV targets for entry into the body) found in the lining of the g*nitals."
