Answer:
The correct answer is - osmosis.
Explanation:
Paramecium lives in freshwater like the Potomac River which is hypotonic to the cytosol of the paramecium. Paramecium uses contractile vacuoles to transport the water from the lower concentration (outside of the cell) to a high concentration of solvent to the inside of the cells.
This process of cell transport is carried out by osmosis as their cytoplasm contains a higher concentration of solutes outside the cell. This excess water is collected into vacuoles called contractile vacuole that swells and finally internalized the water to the outside of the cell.
Thus, the correct answer is - osmosis.
Metabolizing nitrogen in prokaryotes is very important to other organisms since these prokaryotes are able to convert ammonium in the soil to nitrate and, then, the denitrifying bacteria could use the nitrate produced instead of using oxygen in their metabolism in order to release nitrogen molecules. by the denitrification process, thus completing the nitrogen cycle. Without the nitrogen metabolism in prokaryotes, the nitrogen in the atmosphere could not be used or utilized to synthesize essential organic compounds that are needed by other organisms. It is only the prokaryotes that has the ability fixing nitrogen or can do the process of nitrogen fixation.
<span>You needed a quick boost of energy - MONOSACCHARIDE
You wanted to grow strong nails, you haven't eaten in days - PROTEIN
You wanted to grow healthy hair - PROTEIN
You had a race tomorrow afternoon - POLYSACCHARIDE
You were getting ready for hibernation - LIPIDS
You wanted to get bigger muscles - PROTEIN
Your meal will be in a week - LIPIDS
CARBOHYDRATES include monosaccharide and polysaccharides. They provide immediate energy boost or short term energy storage for animals as well as long term energy storage for plants.
PROTEIN s</span>peeds up chemical reactions by lowering activation energy. It is used to form bones and build muscles. It is m<span>ade up of an amino group, a carboxyl group, and an R group.
LIPIDS can be saturated or unsaturated fatty acids. They are not soluble in water however they provide long-term energy storage for animals. </span>
Answer:
Objects able to block all the light are called opaque and will form a shadow. ... The closer an object is to the light source, the larger the shadow it casts. This is because an object closer to the source will block a larger area of the light, increasing its shadow size.
