Explain the central dogma of molecular biology. please don't define it or state what it says.
katen-ka-za [31]

Answer:

The central dogma of molecular biology is an explanation of the flow of genetic information within a biological system. it is often stated as "DNA makes RNA, and RNA makes protein", although this is not its original meaning.This states that once "information" has passed into protein it cannot get out again.

Which statement best describes the evolutionary significance of mutualism?
krok68 [10]

Answer:

C) Interaction increases the survival and reproductive rates of mutualistic species.

Explanation:

A) Mutualism offer more biodiversity to a community.

    Biodiversity is the different species living in one environment. Since mutualism is only involving two species, it wouldn't increase the biodiversity of one ecosystem, making it incorrect.

B) Individuals partaking in a mutualistic relationship relationship are more resistant to parasites.

    Mutualism is only benefiting two species, not their immunity to diseases and parasites. These two have no correlation with each other, making it incorrect.

D) Mutualistic interaction lessens competition in communities where it is present.

    Since mutualism is only benefiting two species, they have no correlation since the relationship doesn't affect the different species in the environment.

E) Mutualistic relationships allow organisms to synthesize and use energy more efficiently.

    Although there could be some relationships involving energy transfer between the species, that would sound more like commensalism or even paratsitism if you think about it. However, it is very uncommon and usually energy has no relationship with species relationships, making it incorrect.

Hope this helps! My deepest apologies if I got in incorrect!

Oksana_A [137]

Answer:

a. Decrease water reabsorption : decrease blood pressure.

b. Decrease peripheral resistance : decrease blood pressure

c. Vasodilation : decrease blood pressure

d. Decrease salt intake : decrease blood pressure

e. Decrease blood volume : decrease blood pressure

f. Vasoconstriction : increase blood pressure

g. Increase peripheral resistance:  increase blood pressure

h. Increase salt intake:  increase blood pressure

i. Increase blood volume : increase blood pressure

j. Increase water reabsorption: increase blood pressure

Explanation:

  • Total peripheral resistance: This term refers to the resistance offered by the vascular system to the blood flow.  This resistance is a result of the friction between the blood and the vessel's walls. In other words, it is the opposition of the vessels to blood flow. The total peripheral resistance is the summary of all the bloody circuit resistances in the body. Those mechanisms that induce vasoconstriction conduce to an increase in total peripheral resistance, while mechanisms that induce vasodilation provoke a decrease in total peripheral resistance.    
  • Blood pressure: This term refers to the strength applied by the blood against the vessel walls as it flows.  This pressure is determined by the bombed blood strength and the volume as well as by the vessel size and flexibility. Blood pressure changes continuously according to the activity, temperature, diet, emotional state, among others.    
  • Salt ingestion causes an increase in plasmatic osmolarity, stimulates thirst, and hence, water ingestion. Sodium retains water, expanding the blood volume and causing an increase in vessel pressure.
  • The antidiuretic hormone, also known as vasopressin hormone, is released by changes in serum osmolarity or blood volume. Its function is to keep homeostasis and make kidneys conserve or keep water by concentrating urine and by reducing its volume. By these actions, the antidiuretic hormone stimulates water reabsorption, according to the organism´s needs.
  • Kidneys control blood pressure in many ways. If the pressure is elevated, kidneys produce the loss of salt and water, normalizing arterial pressure. But if pressure is low, kidneys conserve water.
