e a starch solution inside of a container and place a glucose solution inside of a second container. The student will then place each container into a beaker of distilled water. After 20 minutes, the student will test the water in each beaker for the presence of starch and glucose. Which of the following would be the BEST material for the student to use for the containers holding the glucose and starch solutions?

Consider this situation: you want to reabsorb sodium ions but you do not want to increase the volume of the blood by reabsorbing
choli [55]

Answer:

Increase aldosterone and decrease ADH

Explanation:

Aldosterone causes reabsorption of sodium ions while Antidiuretic hormone (ADH) causes reabsorption of water. Aldosterone also causes water reabsorption due to increased osmotic pressure by reabsorbing sodium ions. But for water reabsorption, Aldosterone has to work along with ADH to increase permeability for water. If we increase Aldosterone and decrease ADH, the sodium ions will be reabsorbed while water cannot be reabsorbed due to decreased permeability of DCT and collecting tubules for water.

xz_007 [3.2K]

Answer:

frontal

Explanation:

  • In a mammalian brain, there are four major lobes that are present and one of them is the frontal lobe.
  • The frontal lobe is mainly rich in dopaminergic neurons and thus, it is mainly concerned with functions such as memory, reward, motivation, planning, attention, etc.
  • The process of break down of tissues and cell death in the tissues is referred to as atrophy and since the frontal lobe is associated with the functions as mentioned above its atrophy would lead to a slow decline in these functions.
  • Since Mr. Klondlike behavior is changing his blunt comments are most likely a result of atrophy of the frontal lobe.

You go for a run and breathe heavily for an extended amount of time. How is this affecting your pH levels?
monitta

You will run and breathe heavily for a long period of time. is affecting your pH levels, Lowering the pH, making it more acidic.

  • A. Lowering the pH, making it more acidic.

<h3>How does respiratory rate affect pH?</h3>

When it is respiratory, it occurs due to an increase in the amount of volatile acids in the body, which lead to an increase in pCO2. When it is metabolic, it occurs due to the accumulation of non-volatile acids, which lead to the loss (excessive consumption) of bases, mainly bicarbonate, causing a drop in pH.

With this information, we can conclude that By eliminating carbon dioxide during expiration, pulmonary ventilation reduces the acidity of the blood, helping it to maintain the desired alkalinity level.
