Answer:

B. External validity

The total fluid or water content of the human body ranges from _____ of its total weight.
likoan [24]

The total fluid or water content of the human body ranges from  <u>30% and 40%</u>  of its total weight.

In an adult male, approximately 60% of the body is made up of water. However, adipose tissue does not contain as much water as lean tissue. Adult females have a higher percentage of their bodies made up of fat than males, accounting for about 55% of their body water.

Total body water weight (TBW) accounts for approximately 60% of total body weight. Whole body water is divided into an intracellular fluid compartment (about 66%) and an extracellular fluid compartment (about 33%). These two spaces are separated by the cell membrane.

The extracellular fluid comprises approximately 20% of total body weight and is further subcategorized as plasma at approximately 5% of body weight and interstitial space which is approximately 12% of body weight.

ValentinkaMS [17]

Answer:

<u>Yes, the executive agreement by the President is valid</u>

Explanation:

An executive agreement is an agreement between the United States (made by the current president) and a foreign government that has the same force as treaties but that is less formal, does not necessarily bind the president's successor and does not need to be ratified by two-thirds of the U.S. Senate in order to become valid like treaties require.

This presidential power is not specifically stated in the U.S. Constitution, however, the president is authorized to have it as one of their powers in the area of foreign affairs. Therefore, the executive agreement that the President made with the foreign leader is completely valid.

How does the rate of a proportional tax change with income?
bija089 [108]

Answer:

B.  The rate remains the same, even if income increases or decreases.

Explanation:

<u>Proportional tex means that the rate of taxes is the same for everyone. It does not change based on someone’s income. </u>Those who earn more pay the same amount of annual taxes as those people whose incomes are low. <u>This system is also called flat taxes.</u>

Some say that this is the way to motivate people to work and earn more, so they can lose less money proportionally to the taxes. Others criticize the proportional tax system as unfair to those who have low incomes.
