The answer : A explanation:
Structure of Plasma Membranes
The primary function of the plasma membrane is to protect the cell from its surroundings. Composed of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules and regulates the movement of substances in and out of cells.

The ears, feet and tail of north american mammals are often smaller in northern species than they are in southern species. Expla
alukav5142 [94]
This phenomenon can be explained by Allen's rule. It says that the body proportions and shape may vary in different climates. The temperature decreases as the latitude increases, so in the northern region is much colder. Animals must preserve heat in such conditions. So, exposed surface areas of the body, such as the ears, feet, and tail, are usually minimized to minimize heat loss in the cold climate. <span>Therefore, northern species often have smaller ears, feet, and tail than the southern species. </span>

A submarine robot is operating near the ocean floor. What pressure and temperature data will it most likely record?
STALIN [3.7K]

The submarine will most likely find data that shows the highest pressure data and the lowest temperature data (unless of course it's near a hydrothermal vent). This is because due to the depth there's a lot more water above it putting a lot of pressure on the sub, and very little sunlight to heat up the water.

Gorter and grendel extracted lipids from human red blood cells. they calculated the total surface area for these red blood cells
Anastaziya [24]
<span>The calculated to surface area for red blood cells by Gorter and Grendel found to be 36u2.

 The surface area that would be covered once they spread across the surface of the water is 72u2.

If they spread across the surface area will double. This is because the lipid bilayer with phospholipid the head faces the water on each surface of the membrane.
 It clearly shows that there must be more to membranes than lipid bilayer because membranes grew and the surface tension of membranes is much lower than those of pure lipid structures.</span>

In a population of 1000 individuals, 500 new individuals were born and 200 individuals died over the course of 1 year. Which equ
blagie [28]

(Initial individuals + newborn individuals) - dead individuals = total individuals

Growth rate = (total individuals/initial individuals) * 100

Population growth rate = new percentage minus 100%

Calculations

(1000 + 500) - 200 = 1500 - 200 = 1300

Growth rate = (1300/ 1000) * 100

= 1.3 * 100

= 130%

Population growth rate = 130% - 100%

= 30% per year if it is uniform
