trapecia [35]

Answer:

She should use the example of "the wave" in stadiums to illustrate the idea of a nerve impulse.

Explanation:

"The wave" in a sport stadium is a good example to explain how a nerve impulse works because it shows how an action potential travels from one point to its destination making changes in the membrane potential that would be the equivalent of people standing up and sitting down to allow the next row to do the same to reach its final destination.

A marine ecologist counts the number of crabs in three different intertidal regions that are each two hectares. The crab counts
romanna [79]

Answer:

Density is nearly 3 cabs per hectare

Explanation:

Given -

There are three three intertidal regions.

Area of each intertidal region is 2 hectares.

Number of crab in the intertidal regions are as follows -

Intertidal region I - 7

Intertidal region I - 2

Intertidal region I - 6

Sum of crabs in all three regions is equal to

7 + 2+ 6\\= 15

Total area of all three intertidal regions is equal to

2 + 2+ 2\\= 6 hectares

Now density per hectare is equal to total population of crab divided by total area of all the three intertidal regions

Density = \frac{15}{6} \\= 2.5

Density is nearly 3 cabs per hectare

Epigenetic alterations are modifications of the genome transmitted during cell division, which do not involve changes in the DNA sequence, are hereditary and are capable of modifying gene expression. In addition, they are temporary modifications that allow DNA to be transcribed and have the ability to move histones to open or close a chromosomal region. There are three main mechanisms of epigenetic alterations: DNA methylation, histone modifications and genomic imprinting.

What is “soil type” to an earthworm?
Evgen [1.6K]

Answer:

Abiotic factor.

Explanation:

Soil type is an abiotic factor for an earthworm. The soil type helps an earthworm to collect food and increase the population.

Sunlight, soil, water, and rocks are those abiotic factors that contribute to earthworms to obtain their food and to survive under the soil or upper side of the soil.

Like earthworms, many other organisms depend on the abiotic factors for their livelihood.
