Answer:


Active transport: movement against a gradient To move substances against a concentration or electrochemical gradient, a cell must use energy. Active transport mechanisms do just this, expending energy (often in the form of ATP) to maintain the proper concentrations of ions and molecules in living cells.

"Which mode of inheritance produces heterozygotes with phenotypes that differ from either homozygote but typically more closely
lyudmila [28]

Which mode of inheritance produces heterozygotes with phenotypes that differ from either homozygote but typically more closely resembles one homozygous phenotype than the other?"

A) complete dominance

B) incomplete dominance

C) codominance

D) epistasis

E) incomplete penetrance

Answer:

B) incomplete dominance

Explanation:

Incomplete dominance occurs when the dominant allele of a gene is not able to mask the expression of the recessive allele completely. This results in the expression of a phenotype in the heterozygous genotypes that differ from both homozygous genotypes. However, the phenotype of the heterozygote is closer to one of the homozygous genotypes.

For example, the petal color in four o'clock plant is controlled by a gene with two alleles R and r. Here, the "R" allele can not produce enough pigment in heterozygous conditions to completely mask the expression of the "r" allele and the phenotype of the "Rr" plant is "pink". On the other hand, the phenotype of "RR" plant is red while that of the "rr" plant is "white".

What sense organs are located on the head and in the mouth of a fetal pig?
Ratling [72]
The sense organs that are located on the head and in the mouth of a fetal pig are the Ears, mouth, eyes, nose, and tongue. The pig, just like humans, experiences sound, sight, taste, smell, heat, cold, pain and also balance. The way it responds to these assists humans in the recognition of health and diseases. For instance pain and the posture will often indicate a specific disease such as a fracture of the vertebrae in the spine.
