Describe the sampling method for determining population size.
DanielleElmas [232]

Some methods of determining the size of population are direct and indirect observations, sampling, and mark-and-recapture studies .

Sampling - Done by counting the animals in a small area and then estimating how many are in the larger area. You go out and take samples from different places so you can take the average. In most cases, it is not possible to count every member of a population so an estimate is made.

Mark and recapture - Another estimating method is a technique called "mark and recapture." This technique gets its name because some animals are first captured, marked, and released into the environment. Then another group of animals is captured. The number of marked animals in this second group indicates the population size.

Indirect observation - The members of a population may be small or hard to find. It may be easier to observe their tracks or other signs rather than the organisms themselves.

Direct observation - The most obvious way to determine the size of a population is to count, one by one.

skad [1K]

Answer:

The correct option is <u>B. Lipids</u>

Explanation:

Lipids can be described as molecules which dissolve in non-polar solvents and cannot dissolve in water. The biological function of a lipid molecule is to store energy as well as to structure the shape of cell membranes. Lipids are also used in a cell for signalling.

Lipids are made up of carbon, hydrogen and oxygen. Some lipids might have phosphorus in them like the phospholipids which make up the cell membrane.

Most mutations
VMariaS [17]
Most mutations have no effect on organisms.  Organisms all have large amounts of genetic code, most of which has no effect.  As a result, mutation of this code is rarely meaningful.
