Which of the following phenotypic classes reflect offspring that were generated as a result of a recombination event?
babymother [125]

Answer:

The correct options are: A " vestigial wings, red eyes" and D "full wings, purple eyes"

Explanation:

female parent: vg+pr+/vg pr

(phenotype - full winged and red eyes)

male parent:  vgpr/vgpr

(phenotype - vestigial winged and purple eyes)

Of these traits, vestigial wings and purple eyes are recessive traits. Hence, when a recombination event occurs, the offspring can potentially have a wild type trait paired with a recessive trait.

Epinephrine has to cross the cell membrane to bind to its receptor in the cytoplasm. True or False
Vinil7 [7]

Answer:

The statement is false.

Explanation:

Epinephrine (also known as adrenaline) is a hormone and a neurotransmitter produced by the adrenal glands, it helps to regulate cellular energy metabolism and increases the heart rate.

Epinephrine adheres to certain receptors that are exposed on the surface of a large number of body cells. This receptor, called beta-adrenergic, is a receptor that is embedded in the plasma membranes of these cells. Adrenaline does not penetrate the cell, instead, joining for a short period of time to its receptor, induces it to release biochemical signals to the cytoplasm of cells. This steric change, affects the configuration of the cytoplasmic domain of the protein, this is the "link" of the receptor that protrudes in the cytoplasm.
