Answer:
B
viscosity of blood causes an increased resistance in the blood vessels and
leads to slow blood flow
Explanation:
Viscosity refers to the thickness of blood. This thickness is caused by the number of red
blood cells. Thick blood travels through blood vessels at a slower rate than thin blood
Answer:
Exposure to a virus is closely related to the development of immunity, since the immune system is responsible for creating antibodies in response to the presence of potentially harmful biological agents, such as these viruses.
Explanation:
Viruses are biological agents that can produce diseases when they enter the body of a living being.<u> In response to contact with a virus, the</u><u> immune system</u><u> synthesizes specific </u><u>antibodies</u> to combat the foreign biological agent.
Antibody immunity can be of two types. It is fast when it is mediated by immunoglobulins M (IgM), which attack the virus anywhere, while the late and prolonged response is due to the development of immunoglobulins G (IgG).
An example of immunity to a virus occurs with the exhibition to the virus of the Dengue, that creates permanent immunity to the viral serotype to which an individual is exposed.
The acquired immunity, mediated by antibodies, is the base for the development of vaccines.
Answer:
<h2>C-A-B</h2>
Explanation:
Given
As given: A and B are 30 map unit apart
A and C are 15 map unit apart
B and C are 45 map unit apart
So the sequence of genes : according to the map unit distance is:
C-A-B
C-15-A-30-B
C-A=15
A-B=30
C-B= 45.
correct order of genes is C-A-B
.
