C. at divergent plates
morpeh [17]3 years ago

The correct answer is option C

The formation of new layer of floor in the ocean is called seafloor spreading. It is a geological process which is caused due to the volcanic activity.

In this the new oceanic crust is formed due to the volcanic activity and the older rocks move away from the mid oceanic ridge.

The new layer formed lies in the middle of the ocean and the older rocks or floor moves aside.

This process occurs due to the divergent plates and the gap between them increases forming new oceanic ridge.

<u>Answer</u>:

C) They invade the body and can cause a humoral immune response.

This best explains the impact that pathogens in the environment might have on one's body.

<u>Explanation</u>:

Pathogens are the microorganisms that are found in the environment and have the tendency to cause diseases. The human body has various lines of defenses against the incoming pathogens, the Nonspecific responses keep the pathogens outside the body and these responses are common for all pathogens. If a pathogen manages to enter the body, then a series of specific responses are triggered which are focused on the type of pathogen.

The humoral response is a category of specific immunity and involves the substances found in body fluids. It particularly targets the newly invading pathogens. Hence, option C correctly describes the impact of pathogens on the body.

Fatty acid metabolism disorder is an autosomal recessive disorder. Two unaffected parents have 6 children - all of whom are unaf
Nadusha1986 [10]

Answer:

There are only 2 possible genotypes for the mother, FF and Ff.

Explanation:

Because it is an autosomal inheritance, this case F will be the dominant allele and f the recessive allele, where f produces Fatty acid metabolism disorder. If the mother does not possess the disorder, she must possess at least one dominant allele for that specific gene. However, for the other allele, we cannot assure that it is dominant, since it can be recessive and not express itself either in her or in the offspring, because of the father we also only know his dominant allele.
