Answer:
D
Explanation:
Facilitated diffusion is a form of passive transport hence no energy is required by the cell. This means that while the molecules are moving down a concentration gradient – line normal diffusion – the movement of the molecules needs to be facilitated (in this case by a transmembrane protein) either because the molecule is polar and can't pass through the hydrophobic region of the cell membrane, or the molecule is too big to passively pass through the small natural pores of the cell membrane.
Hello :3 :3
Your question is related to genetics.
Taking a look at your question, A is dominant and axial, while a is recessive and terminal.
If you cross-breed these two pea plants, and you drew the Punnett square, you would end up with Aa (100%) heterozygous on the F1 generation.
Now, on the F2 generation, you would end up with AA (25%) - Aa (50%) - aa (25%). AA is homozygous dominant, Aa is heterozygous, and aa is homozygous recessive.

Answer:
The protists refer to the unicellular eukaryotic species, which comprise algae, fungi, and protozoa. Of these some are autotrophs and some are heterotrophs. They exhibit the tendency to survive in aquatic surroundings because of their feeding habits.
In older approaches, protists are categorized on the basis of their morphology. However, by using novel approaches like molecular genetics, they are being categorized on the basis of their genetics.
