Can someone check these for me?

1. Excretion is the process of (1 point)
exchanging carbon dioxide for oxygen.
removing metabolic wastes from the body.***
pumping blood throughout the body to supply nutrients and oxygen to cells.
breaking food down into nutrients that can be absorbed.

2. Kidneys that can conserve water are essential to homeostasis because (1 point)
some animals live in dry or salty environments.
some animals drink water.
urea is not soluble in water.***
their cells will be unable to convert ammonia into urea if excess water is excreted.

3. Many freshwater invertebrates eliminate ammonia by (1 point)
converting it to uric acid and eliminating it with solid wastes.
simple diffusion across the gill membranes.
converting it to urea and eliminating it in their urine.
simple diffusion across the skin.***

4. Which of the following excretory processes do saltwater and freshwater fishes share? (1 point)
They both conserve water by producing small amounts of concentrated urine.
They both actively pump salt across their gills.***
They both avoid drinking water.
They both produce lots of watery urine.

5. What excretory characteristic does a garden spider share with a sparrow? (1 point)
They both convert nitrogenous wastes to uric acid.
They both produce lots of diluted urine.***
They both excrete very concentrated salt solutions.
They both produce very dry feces.

1. B

2. A
3. D
4. B
5. A

I can confirm that a.normal.tree is correct :)!

3. Many freshwater invertebrates eliminate ammonia by
D. Simple diffusion across the skin.
4. Which of the following excretory processes do saltwater and freshwater fishes share? (1 point)
B. They both actively pump salt across their gills.
5. What excretory characteristic does a garden spider share with a sparrow? (1 point)
A. They both convert nitrogenous wastes to uric acid.
5/5 100%

2 and 5 are wrong for anyone who may use this to answer their test

2&5 is the first answer choice

2) some animals live in dry or salty environments.
5) They both convert nitrogenous wastes to uric acid

To check the answers to these questions, we can go through each answer choice and see if it matches the correct response.

1. The correct answer is "removing metabolic wastes from the body." To check this, we can look at the other answer choices and see if any of them fit better. "Exchanging carbon dioxide for oxygen" is the process of respiration, not excretion. "Pumping blood throughout the body to supply nutrients and oxygen to cells" is the process of circulation, not excretion. "Breaking food down into nutrients that can be absorbed" is the process of digestion, not excretion.

2. The correct answer is "urea is not soluble in water." To check this, we can look at the other answer choices and see if any of them fit better. "Some animals live in dry or salty environments" is true, but it doesn't specifically relate to the conservation of water by kidneys. "Some animals drink water" is also true, but it doesn't explain why kidneys that can conserve water are essential to homeostasis. "Their cells will be unable to convert ammonia into urea if excess water is excreted" is the correct explanation for why kidneys that can conserve water are essential to homeostasis.

3. The correct answer is "simple diffusion across the skin." To check this, we can look at the other answer choices and see if any of them fit better. "Converting it to uric acid and eliminating it with solid wastes" is a method of ammonia elimination used by some terrestrial animals, not freshwater invertebrates. "Converting it to urea and eliminating it in their urine" is a method of ammonia elimination used by mammals, not freshwater invertebrates. "Simple diffusion across the gill membranes" is the method of ammonia elimination used by many freshwater invertebrates.

4. The correct answer is "They both actively pump salt across their gills." To check this, we can look at the other answer choices and see if any of them fit better. "They both conserve water by producing small amounts of concentrated urine" is true for saltwater fishes, but not for freshwater fishes. "They both avoid drinking water" is true for saltwater fishes, but not specifically related to excretory processes. "They both produce lots of watery urine" is true for freshwater fishes, but not for saltwater fishes.

5. The correct answer is "They both produce lots of diluted urine." To check this, we can look at the other answer choices and see if any of them fit better. "They both convert nitrogenous wastes to uric acid" is not true for a sparrow, which excretes uric acid as a solid waste. "They both excrete very concentrated salt solutions" is not true for a garden spider, which excretes diluted urine. "They both produce very dry feces" is true for a garden spider, but not for a sparrow.

By checking each answer choice against the correct responses, we can determine if the answers provided are correct.

Can someone help?!?

Did u get the answers
