Answer:
Los puentes de Hidrógeno, se forman por átomos de Hidrógeno localizados entre átomos pequeños muy electronegativos, cuando un átomo de Hidrógeno está unido covalentemente, a un átomo electronegativo, Oxígeno, Nitrógeno o Flúor, el átomo con mayor electronegatividad atraerá hacia si los electrones del enlace, formándose

Riparian zones can reduce the impact of water pollution is true.
The statement is true.
<h3 /><h3>What are Riparian zones?</h3>
The areas along the banks of rivers and other sources of surface water are known as riparian zones.
The floodplain and riparian buffers bordering the floodplain are included.
Riparian zones benefit streams, groundwater, and downstream land areas in numerous ways, both environmentally and recreationally.
Thus, the given statement is true.

Answer:
C. Population shrinks; 15 birds in the end
Explanation:
Let us understand some of the given terms;
immigration is a form of migration in which organisms comes into a territory.
emigration is a form of migration in which organisms leaves a place
population is a group of organisms of the same species
Given:
Population = 21 birds
Immigrant = 3 birds
Emigrants = 9 birds
Population change = total number of birds + immigrant - emigrants
= 21 + 3 - 9
= 15 birds
The population will shrink giving 15 birds in the end
Neural control of GFR is mediated by Sympathetic neurons that innervate alpha receptors on vascular smooth muscle causing Vasoconstriction.
<h3>How is GFR regulated?</h3>
- The sympathetic division of the nervous system regulates the GFR or Glomerular Filtration Rate.
- GFR is the sum total of filtration rates of all the working nephrons in the kidney.
- Sympathetic division comes into action when the mean arterial pressure is very low (below 80mmHg).
- In response to low blood pressure, the medulla releases norepinephrine through sympathetic nerves.
- Norepinephrine leads to activation of alpha receptors on arteries which cause vasoconstriction.
- Alpha receptors are more abundant on afferent arterioles.
- This leads to vasoconstriction (narrowing) of arteries supplying to the glomerulus.
- This decreases blood flow to glomerulus, leading to decrease in GFR.
