Answer:The answer is diffusion.
Explanation: Unicellular organisms excrete waste by diffusion.
Unicellular organisms are organisms that have only one cell. They are called single cell organisms because all their life processes such as reproduction, feeding, digestion, and excretion, occur in only one cell. An example of unicellular organism is paramecium.
Diffusion is the inactive movement of molecules from the region of higher concentration to the region of lower concentration.
The driving force of photosynthesis is the energy that is contained in sunlight. This energy is transformed to energy that plants and other organisms use to live.
Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.
Answer:
No, the vitamins from the two sources are not different.
No, the body cannot distinguish a vitamin's source.
Explanation:
Pure L-ascorbic acid extracted from rose hips is identical in every way to pure L-ascorbic acid synthesized in a plant.
The only difference that might distinguish the two is the presence of impurities such as byproducts or solvents used in the process of extraction or synthesis. However, "pure" implies that no such impurities are present.
The possible answers are
<span>A.a drought reduces the toad population </span>
<span>B. an influx of soil nutrients results in increased grass growth </span>
C.a hawk species moves in that hunts toads
<span>D.the toad population increases after a warm, wet spring
The correct answer is D
The increase in numbers in the toad population after a warm and wet spring would mean that there are more toads that prey on the beetles and that they are limiting the beetle population by hunting them.</span>
