What factor determines is some molecules can pass through a membrane

Biology
1 answer:
Yanka [14]3 years ago
7 0

Answer:

Explanation:The ability of a molecule to travel across a membrane depends on its concentration, charge and size. In general, molecules diffuse across membranes from areas of high concentration to low concentration. Cell membranes prevent charged molecules from entering the cell unless the cell maintains an electrical potential

Answer:

Flippases.

Explanation:

Cell membrane is made of lipid bilayer and proteins are inserted or span the bilayer. Carbohydrates are attached in association with lipids and proteins in the bilayer membrane.

The enzymes are important for maintenance of the proper structure and function of the membrane. Flippase are the enzymes located in the membrane and belong to ABC transporter family. This enzyme maintain the growth and regulation of halves of the bilayer and transport lipids from one site of the membrane to the another site.

Thus, the answer is flippase enzyme.

What is the answer to this question?"explain two difficulties an ecologist might have in counting a population of migratory bird
dimulka [17.4K]
<span>It may be difficult for ecologists to determine the size of a bird population if that population migrates to different locations throughout the year. During migration, some birds may split off from the group and not return, others may die, and still others may join. Therefore, the bird population will be in constant flux. It is hard to know, when the birds return to their prior location, if the population consists of the same group of birds (in addition to deaths and births) or whether it has grown or shrank through other means. However, to estimate the size, an ecologist can track a migratory flock through several years, counting each year to get a general sense of the population size. Additionally, given one measurement, an ecologist could consider the average lifespan and birth rates of the population to extrapolate the size of the population in subsequent years.</span>
