Answer:
C.) They self-fertilize
Explanation:
Mendel used pea plants because they self fertilized, meaning that the plant could supply a sperm and egg cell so it could produce its own offspring. This makes the process of looking at genetics and traits much easier for the scientist studying the genes of plants.
Answer:
Epinephrine is both a hormone and a neurotransmitter, so is considered a chemical that acts on the type of endocrine intercellular signaling.
Explanation:
Epinephrine, or adrenaline, is produced by the marrow of the adrenal gland, under the coordination of the central nervous system.
Epinephrine is a molecule that acts as a hormone or neurotransmitter, being able to achieve physiological changes by binding to specific cell receptors. This type of action generates changes inside the cell. As this molecule is produced in one cell and is coupled to the receptor of another cell, it performs the type of endocrine intercellular signaling.

Answer: restriction endonuclease.
Explanation: restriction endonuclease recognize a specific site at a DNA molecule called restriction site and attach to it and cleave DNA into pieces by the cleavage of phosphodiester bond. Restriction site are few nucleotides in length found in the middle of the polynucleotide chain.
