Answer:

Polygenic trait.

Explanation:

A polygenic trait is the one that is regulated by more than one genes. Here, the total number of dominant alleles of all the genes determine the phenotype of the individuals.  

For example, human skin color, height, eye color, the color of hair, etc. are polygenic trait and is regulated by more than one gene.

Before the forming urine flows into the distal tubule of the nephron, it is in the _____ ______ _____, where water is absorbed a
liraira [26]

Answer:

<em>"Before the forming urine flows into the distal tubule of the nephron, it is in the </em><em>loop of Henle</em><em>, where water is absorbed as the fluid descends into the deep medulla of the kidney, and salts are absorbed as the fluid flows back up to the cortex of the kidney".</em>

Explanation:

Henle´s loop is a specific section of renal tubules that forms the nephrons.

In this U-shaped region, the two parts of the contorted tubule, the distal and the proximal part, are very close to each other. In the kidney, both parts of the tubules are located in the renal cortex, while the loop of Henle is located within the renal medulla.

The proximal region of the Henle´s loop is a permeable region, unlike the proximal and distal regions of the renal tubule.  

This is why it is possible the interchange of water and ions in the Henle´s loop. In the loop´s walls, cells present aquaporines in their membranes that allow passive water absorption, while they do not allow the transport of ions and urea. In this way 25% of the water that passes through the kidney might be filtered.  

The ascendant side of the loop, which is narrower, the tubule wall is impermeable to water but allows the ions´reabsorption. Here, cells present sodium, potassium, and chloride channels.

Potassium sodium pump transporters are found in the basolateral zone. While in the apical area are active transporters of the 3 ions.

Due to these differences in the water and ions´absorption between the two parts of the Henle´s loop, a countercurrent multiplier effect is produced, stratifying the osmotic compounds of the medullary interstitium, being the part closest to the cortex less concentrated than the part closest to the renal papilla, which is about 4 times more concentrated in ions.

Explain how critical value variations influence statistical power.
zloy xaker [14]
Statistical power is the likelihood that a test (statistical test) will detect an effect when there is an effect there to be detected. Statistical power<span> is inversely related to </span><span>the probability of making a </span>Type II error (Type II errors<span>, or </span>false negatives, occur when you don’t see things that are there) = beta<span>.
statistical power = 1 – </span>β. The critical value<span> is the </span>value corresponding to a given significance level.  The statistical power<span> is </span>influenced by the choice of significance level for the test (by the critical value). Larger critical value means increased power of the test: <span> the chance of obtaining a statistically significant result is increased (reduces the risk of a </span>Type II error<span> (false negative regarding whether an effect exists) is reduced) . </span>
