Which characteristic differentiates amphibians from reptiles?
Stells [14]

Option D – amphibians may use their skin for gas exchange is the characteristic feature of amphibians that differs from reptiles.

Explanation:

The amphibian skin is moist, thin and marbled and supplied by blood vessels running on its surface. The moisture present in the skin dissolves the oxygen present in its surrounding which is absorbed by the blood vessels. Special glands help the amphibians to keep the skin moist.

The very thick and tough scales present on the reptiles prevent them to absorb oxygen through their skin. Hence, they breathe and respire through their lungs.

Amphibians have three-chambered heart. They do not develop amniotic eggs. Adult amphibians although spend much time on land, they breed only in water due to the absence of amniotic sac .

What is one potential result of climate change that could inhibit (reduce) kelp's ability to do photosynthesis?
Bogdan [553]
One potential result of climate change is greenhouse effect that is defined as the accumulation of carbon dioxide in the atmosphere that retains heat radiated from the sun. While this can seem beneficial because plants use carbon dioxide in photosynthesis, elevated levels of carbon dioxide actually inhibit photosynthetic mechanisms (Xu, 2015).

Katyanochek1 [597]

Water-soluble vitamin excesses are swiftly eliminated in urine and infrequently build up to hazardous amounts.

What is water-soluble vitamins ?

The B vitamins — folate, thiamine, riboflavin, niacin, pantothenic acid, biotin, vitamin B6, and vitamin B12 — and vitamin C are the nine water-soluble vitamins. A clinical condition caused by a deficiency in one or more of these water-soluble vitamins can have serious morbidity and death effects.

The fat-soluble vitamins are used by your body as needed, and any extra is stored in your tissues and organs. The risk of vitamin poisoning increases when you take too much fat-soluble vitamins on a regular basis, making them more dangerous than water-soluble vitamins.
