Answer:
D) Frequency results from environmental stresses, not dominance.
Explanation:
The allele frequency refers to the amount of frequency of a particular allele in a small population whereas the dominance and recessive are the measure of the effects of the allele on the population which decides the trait of an organism.
The frequency and dominance cannot be correlated with each other as the frequency of the allele in a population is the result of the environmental stress which are random and by chances, whereas the effect of dominance is not random but is the result of the favoured trait for survival.
Thus, Option-D is correct.
Aldosterone from the adrenal gland is the answer
Answer:
The correct answer will be option-A
Explanation:
The Mosses are the non-vascular plants that were developed from the aquatic plants and the ferns are the vascular plants which developed from the bryophytes.
Their life cycle shows alternation of generation and is largely dependent on the water for reproduction mainly fertilization or fusion of gametes.
The male gametes produced in these plant groups are haploid and are released in water which fuses in water with female gamete which is distinct from the higher plant groups gymnosperms and angiosperms where fertilization is mediated by mostly the wind or insects.
Thus, option-A is the correct answer.
Answer: I included a labeled graph of both a plant cell and an animal cell. I don't know if you needed an explanation of what they do, too, but I'll include it anyway.
Explanation:
The Cell Membrane, or plasma membrane, provides protection for the cell. It also transports substances in and out of the cell.
The Cell Wall (only plants) provides the structure for a plant, as well as added protection.
The Mitochondria are the powerhouse of the cell, providing energy for our cells to do their work. They produce a small molecule called ATP (adenosine triphosphate), where the energy is stored and sent to where it is needed.
The Lysosomes are the waste facilities of cells. They breakdown excess or worn-out cell parts, destroy foreign or invading bacteria, and digest macromolecules (carbs, lipids, proteins, and nucleic acids)
