The
correct answer is they filter urea from blood and produce urine.
<span>
Nitrogenous
wastes tend to form toxic ammonia which needs to be removed. Terrestrial
animals must detoxify ammonia by converting it into a relatively nontoxic molecule-urea
(it occurs in the urea cycle). The urea cycle mainly occurs in the liver and the
produced urea is then released into the blood. It travels to the kidneys where
is filtrated and excreted in urine.</span>
I think the correct answer from the choices listed above is the first option. The male <span>reproductive system is different from other body systems in a way that </span>it isn’t necessary to vital signs. The vital signs are <span>Body </span>temperature, Pulse<span> rate, </span>Respiration rate<span> (rate of </span>breathing<span>) and </span>Blood pressure which does not include the male <span>reproductive system.</span>

Answer:
Explanation:
In general, frogs have protruding eyes, no tail, and strong, webbed hind feet that are adapted for leaping and swimming. They also possess smooth, moist skins. Many are predominantly aquatic, but some live on land, in burrows, or in trees.
Answer:
a. glycolysis—preparatory reaction--cirtric acid cycle--electron transport system
Explanation:
- Glycolysis is the first stage of cellular respiration that occurs in the cytoplasm of the cell. During glycolysis one 6 carbon glucose is converted into two molecules of 3 carbon pyruvic acid or pyruvate.
- In the preparatory reaction, the pyruvate converted into a two-carbon molecule called acetyl CoA. In this reaction, a carbon dioxide molecule is released and a molecule of NADH is released.
- The citric acid cycle begins with the reaction of the acetyl CoA with a four-carbon molecule in the mitochondrisl matrix. It goes through a cycle of reactions regenerating the four-carbon starting molecule. ATP, NADH and FADH₂ are produced.
- The electron transport system is the terminal step of aerobic respiration that operates on the inner membrane of the mitochondria. Reduced coenzymes NADH and FADH₂ move along electron transport system release high-energy electrons and produce ATP.
