Answer: The question is incomplete, the image is not given.

Option B is the answer.

Primary succession after volcanic eruption.

Explanation:

Primary succession occur when new land are formed from an habitat that has not been colonized before. It occurs when a disaster like volcanic eruption occur in a place and takes the soil. It is characterized by regions with absence of soil and living organisms. Primary succession start with pioneer species like lichens , algae and misses that can grow on bare rocks.

Answer:

b. primary succession after a volcanic eruption

Explanation:

The image (see the attached image), represents primary succession after a volcanic eruption.

Succession general refers to the process of gradual change in the species composition of a community over a long period of time. There two types of succession:

Primary succession: This represents a change that occur on a new site that has not held any previous community before. New species that colonize such sites are referred to as pioneer species.
Secondary succession: A kind of changes that occur after a community has undergone a disturbance regime.

Both primary and secondary succession eventually lead to a relatively stable community (climax community) in the long run if there are no incidence of disturbance.

The image represents a site that has just witnessed a volcanic eruption. the newly formed site has no history of any community of organisms before. Species of organisms found growing on this site are the pioneer species. Hence, this kind of succession is primary.

The correct option is b.

What is the difference between a compound microscope and an electron microscope

WARRIOR [948]

Compounds microscope is an optical instrument for forming magnifying images of small objects having an objective Len with a very short focal length. While electron microscope is a high power of microscope uses beam of electron focused by magnetic lenses instead of rays of light.

In a worm what part of the digestive system would you see in a cross-section anterior to the gizzard

Kamila [148]

Crop is the part of the digestive system you would see in a cross-section anterior to the gizzard in a worm. Crop is a thin wall organ that acts as a temporary food storage chamber. The esophagus leads to the crop and the organ next to it is the gizzard which serves as the food grinding chamber.

The human MN blood type is determined by two codominant alleles, L(M) and L(N). The frequency of L(M) in Eskimos on a small Arct

tatiyna

Answer:

(a) Frequency of M = 0.64

Frequency of N = 0.04

Frequency of MN= 0.32

(b) Expected frequencies of M = 0.648

Expected frequencies of MN = 0.304

Expected frequencies of N = 0.048

Explanation:

(a) If random mating takes place in the population, then the expected frequencies are

f(L(M)) = p = 0.8

F(L(N)) = q

q= 1 - p

= 1 - 0.8

= 0.2

Frequency of M = p^2 = ( 0.8)^2 = 0.64

Frequency of N = q^2 = (1-p)^2 = (1 - 0.8)^2 = (0.2)^2 = 0.04

Frequency of MN = 2pq = 2 * 0.8 * 0.2 = 0.32

(b)

F = inbreeding coefficient = 0.05

f(L(M)L(M)) = p^2 + Fpq = (0.8)^2 + 0.05 * 0.8 * 0.2 = 0.648

f(L(M)L(N)) = 2 pq - 2Fpq = 2 * 0.8 * 0.2 - ( 2 * 0.05 * 0.8 * 0.2) = 0.304

f(L(N)L(N)) = q^2 + Fpq = (0.2)^2 + ( 0.05 * 0.8 * 0.2) = 0.048

As a small change in a person's DNA can cause a genetic disorder

zzz [600]

Affirmative, that is correct.

A genetic disorder is nothing more than an abnormal occurrence in a genome, which means that if you change DNA you'll change the genome, and if the change isn't acceptable, genetic disorders can occur easily.

Genetic disorders is a fun field within genetics, and it isn't easy. The functioning of a gene might be an easy concept now a days, but we haven't mastered it. For example, it's not like maths:

- Somebody comes up with a new, unsolved problem, and tries to solve it, and while doing that, the person can create laws, theorems, equations, etc.

Once you come up against a genetic disorder (you can't just create a genetic disorder to study it) you have to study the genetic disorder itself, what caused it and why.

Hope it helped,
