The skin is like the urinary system because
Correct Answer
it gets rid of body wastes
it removes wastes from the bodyExplanation
The skin is like the urinary system because it gets rid of body wastes and removes wastes from the body. The skin plays a vital role in excretion by eliminating sweat, which contains metabolic waste products such as urea and salts. This process helps maintain the body's homeostasis by regulating temperature and removing toxins. Similarly, the urinary system filters waste products from the blood and eliminates them through urine. Both systems contribute to the overall elimination of waste from the body.Rate this question:

It is important to take a bath or shower after you have been sweating because
Correct Answer
urea and salts stay on the skin until you wash them offExplanation
When we sweat, our body releases urea and salts onto the surface of our skin. If we don't wash them off, they can remain on the skin, leading to a buildup of bacteria and unpleasant body odor. Additionally, leaving sweat on the skin for a prolonged period can cause irritation and clog pores, potentially leading to skin problems such as acne. Therefore, it is important to take a bath or shower after sweating to remove these substances and maintain good hygiene.Rate this question:

Why do people sweat more in the hot summers than they do in the cool winters?
- A.
The temperature is hotter so the skin sweats more often
- B.
They workout more in the summer than they do in the winter
- C.
That is just part of nature
Correct Answer
A. The temperature is hotter so the skin sweats more oftenExplanation
In hot summers, the temperature is higher, causing the body to heat up. To cool down, the body produces sweat, which evaporates and cools the skin. This is a natural mechanism that helps regulate body temperature. In cool winters, the temperature is lower, so the body does not need to produce as much sweat to cool down. Therefore, people tend to sweat more in hot summers than in cool winters due to the higher temperature.Rate this question:

Correct Answer(s)
B. Made up of cells that can contract and relax.
C. Allows the body to make internal and external movements.Explanation
Muscle tissue is made up of cells that can contract and relax, allowing the body to make internal and external movements. This is because muscle cells contain specialized proteins that can interact and generate force, leading to muscle contraction. Additionally, muscle tissue supports and connects other tissues in the body, providing structural integrity and enabling movement. However, muscle tissue does not consist of tightly-packed cells that form a covering for the skin and line the hollow internal organs, which is a characteristic of epithelial tissue.Rate this question:

Correct Answer
B. Tightly-packed cells which form a covering for the skin and line the hollow internal organs.Explanation
The correct answer is "Tightly-packed cells which form a covering for the skin and line the hollow internal organs." This is because epithelial tissue is composed of tightly-packed cells that form a protective covering for the skin and also line the hollow internal organs. Epithelial tissue is responsible for functions such as protection, absorption, secretion, and sensation. It does not carry electrical signals between the brain and other parts of the body, nor does it allow the body to make internal and external movements.Rate this question:
