Biology

<span>The answer to the first question is letter B. This is because disruptive selection is opposite to stabilizing selection which decreases genetic variation or genetic diversity. Among the choices on the second question, the second option (B) is the most plausible because it could mean "difference within the same specie". This video would likely to show sexual isolation.</span><span />

Which form of natural selection does a graph repeat
Nookie1986 [14]
May i have choices but <span>Natural selection can take many forms. To make talking about this easier, we will consider the distribution of traits across a population in graphical form. In we see the normal bell curve of trait distribution. For example, if we were talking about height as a trait, we would see that without any selection pressure on this trait, the heights of individuals in a population would vary, with most individuals being of an average height and fewer being extremely short or extremely tall. However, when selection pressures act on a trait, this distribution can be altered.</span>

g100num [7]

Answer:

The correct answer is- olfactory nerve(1)

Explanation:

Olfactory nerve is the first nerve out of the 12 cranial nerve that is located in the head and is also the shortest of all the cranial nerve. The receptors of the olfactory nerve are present in the nasal mucosa that passes to the forebrain.

It pass sensory information of smell to the brain so it plays the sensory function in smell perception. The damage to olfactory nerves can lead to:

Anosmia: In anosmia, people lose their ability to smell.

Hyposmia: In this condition, the ability to smell gets reduced.

Dysosmia: In this situation, people lost their ability to distinguish between various types of smell.

So the right answer is olfactory nerve(1).

Be able to compare/contrast humoral immunity with cellular immunity.
aksik [14]

Solution:

The difference between them are:


The humoral system of immunity is also called the antibody-mediated system because of its use of specific immune-system structures called antibodies. The first stage in the humoral pathway of immunity is the ingestion (phagocytosis) of foreign matter by special blood cells called macrophages. The macrophages digest the infectious agent and then display some of its components on their surfaces. Cells called helper-T cells recognize this presentation, activate their immune response, and multiply rapidly. While,


The cell-mediated immune response involves cytotoxic T-cells, or killer-T cells. Body cells that have been infected by foreign matter often present components of that material on their surfaces. Killer-T cells recognize these displays and respond by ingesting or otherwise destroying the infected cell. Killer-T cells are also important in the body's defenses against parasites, fungi, protozoans, and other larger cells that might have found their way into the body. The killer-T cells recognize these large invaders by their foreign proteins and then destroy them.  

This is the required answer.
