Which of the following best explains why humans need constant supplies of fresh water?a. Humans need a constant supply of water to provide them with essential vitamins.
b. Humans need a constant supply of water to maintain proper hygiene.
c. Constant supplies of freshwater are needed because body water is continually being lost.
d. Constant supplies of freshwater are not actually necessary for survival.

Answers

Answer 1
Answer: The answer is C. The body needs constant supply of water because the water in the body is continually lost. On the average, our body contains approximately 60% of water and most of the water is inside the cells. however, this value varies depending on the age.  As we do our day to day activities, we lost water through sweating, urinating and by other means. Cells need water in order for them to live thus it is a must that we supply our body with water.
Answer 2
Answer:

Constant supplies of freshwater are needed because body water is continually being lost through metabolic processes etc.

What is Water?

This is referred to as a universal solvent and is composed of the chemical elements hydrogen and oxygen.

Water is useful in the body's metabolic processes such as digestion and homeostasis. Water is also lost through evaporation which is why it must be constantly supplied and the reason option C was chosen.

Feather color in budgies is determined by two different genes Y and B. YYBB, YyBB, or YYBb is green; yyBB or yyBb is blue; YYbb or Yybb is yellow; and yybb is white. Two blue budgies were crossed. Over the years, they produced 22 offspring, 5 of which were white. What are the most likely genotypes for the two blue budgies?

Answers

Answer:

The most likely genotypes for the two blue budgies would be yyBb

Explanation:

There are three options to cross two blue parakeets:

yyBB x yyBB

yyBB x yyBb

yyBb x yyBb

of the first option, the F1 genotypes will be 100% yyBB  (blue)

In the second option, the F1 budgies will be yyBB or yyBb (blue in both cases). In contrast, in the third option, the F1 genotypes will be yyBB, yyBb (blue in both cases) and yybb (white).

The _____ tube brings a mature ovum to the uterus. fallopian ovarian Cowper

Answers

The correct answer is fallopian tube.

The fallopian tube, also known as uterine tube or oviduct, carries the egg from ovary to the uterus.

 The fallopian tube has finger-like projections or branches called fimbriae  which   reach out into the pelvic cavity and pick up an egg that has been released from the ovary.

The egg is tenderly brought into the fallopian tube where it begins to travel to the uterus.

The fallopian tube also serves as the location where fertilization of the egg by a sperm cell occurs.

Of all of the biomes, this is where you will find the large, ground-dwelling megafauna. this biome is characterized by tall grasses and some scattered trees.

Answers

The answer is Tropical Savannah.

It is a biome characterized by scattered trees and grasses. It falls between the region of tropical rein-forest and deserts biome. This region is not favorable for vegetation because not much of rain falls here.

Generally, savannah has two different seasons; a very long dry season and a very long wet season. In dry season, an average of 4 inches of rain falls and oddly it is a little cool here during dry season.


Is the importance of an element in the body related to its percentage of body weight? Cite the evidence in the table to support your explanation.

Answers

Yes, the importance of an element in the body related to its percentage of body weight.

That element that is present in a large amount are more important for the structure and function of the body. The human body is approximately 99% consist of six elements which is Oxygen, hydrogen, nitrogen, carbon, calcium, and phosphorus.

The five elements are present in 0.85% on the basis of boy weight which is sulfur, potassium, sodium, chlorine, and magnesium so we can conclude that percentage of element in the body tells us about its importance.

Final answer:

The importance of an element in the body is not solely based on its percentage of body weight. Elements' importance is determined by their function and essentiality to biological processes. Oxygen, although abundant in the body, is necessary for cellular respiration and energy production.

Explanation:

The importance of an element in the body is not directly related to its percentage of body weight. While some elements may have a higher percentage in the body, their importance is determined by their function and essentiality to biological processes.

For example, oxygen is the most abundant element in the body and has a high percentage of body weight. This is because oxygen is essential for cellular respiration and energy production.

On the other hand, elements like iodine and iron may have a lower percentage in the body, but they are crucial for functions like thyroid hormone synthesis and oxygen transportation, respectively.
