Answer:
c.cross-sectional
Explanation:
Cross-sectional study is a kind of research which compares different population groups at one specific point in time.
Here, the researcher compares three population groups (first grade, third grade, and sixth grade of elementary school). By using this method, any differences between age groups regarding reasoning ability can be related to age differences not something that happened over time.
Answer: lessening the influence of eastern landowners in politics.
Andrew Jackson was the first president from the area west of the Appalachians. Moreover, much of the leadership in his campaign was also from the West. This led to a realignment of power, in which eastern landowners lost some of their influence in politics. This was a turning point in the politics of the United States, and helped establish Jackson as the president of the "common man."
Dr. Smith is conducting a longitudinal case where it is a case being done in a same manner over a long period of time. It could be seen above as Dr. Smith has instructed his representatives to go back every five years to conduct the same measurement in a course of a long period which is until they are sixty years old which could be classified as the longitudinal case.
Answer:
Genesis 1 states that the Spirit of God was hovering over the waters . For Christians, it was the Spirit of God that created the universe out of nothing. This is important because it shows that God is omnipotent and the source of all life.
Explanation:
Osmoreceptors within the hypothalamus detect and increase in plasma osmolarity. This results in a decrease in ADH release from the posterior pituitary, and hence decrease in water permeability of the collecting duct.
<h3>What is osmoregulation?</h3>
Osmoregulation is that the active regulation of the osmotic pressure of an organism's body fluids, detected by osmoreceptors, to take care of the homeostasis of the organism's water content; that is, it maintains the fluid balance and therefore the concentration of electrolytes to keep the body fluids from becoming too diluted or concentrated.
The tendency of water to move into one solution from another by osmosis is osmotic pressure. The upper the osmotic pressure of a solution, the more water tends to maneuver into it.
<h3>Osmoregulation through kidney :</h3>
Pressure must be exerted on the hypertonic side of a selectively permeable membrane to stop diffusion of water by osmosis from the side containing pure water. Although there could also be hourly and daily variations in osmotic balance, an animal is usually in an osmotic steady state over the long term.
Organisms in aquatic and terrestrial environments must maintain the proper concentration of solutes and amount of water in their body fluids; this involves excretion (getting rid of metabolic nitrogen wastes and other substances such as hormones that would be toxic.
