lys-0071 [83]3 years ago

Answer:

When the required direction of transport is opposed to concentration levels, a cell <u>will </u> expend energy to force<u> ions</u> across its membrane.

Explanation:

If the concentration gradient is opposite to the direction of transport of minerals, then the cell will use energy to transport mineral ions from a lower concentration to a higher concentration. The most common process through which this happens is termed as the active transport.

The process of active transport is opposite to passive transport. In passive transport, molecules move from a higher concentration to a lower concentration.

What happens if food items with excessive moisture are placed directly into hot shortening?
Olenka [21]

The excess moisture ( water) in the food items boils up immediately and busts both shortening and water around.

<h3>Reaction between hot shortening and water</h3>

Shortening are known to be fats at room temperature and are usually used in the baking of cakes and bread.

When placed in the temperature that is high, it melts to become liquid.

When you pour a food item that contains excess moisture on hot shortening, the water comes in contact with a higher temperature than the shortening's boiling temperature, so the water starts boiling immediately, and busts both shortening and water around.

How do plants and snails affect the CO2 and O2 gases in an aquatic environment
frez [133]

Answer:

Water plants will absorb carbon dioxide for photosynthesis, and some plants will also absorb ammonia (as a source of nitrogen for growth). Aquatic animals like fish and snails absorb oxygen and release carbon dioxide directly into water through specialized structures like gills.

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 .
