Recessive traits often seem to disappear because two recessive alleles are needed to produce the recessive phenotype. They can skip a generation and then reappear if an individual inherits two copies of the recessive gene. Mendel's experiments revealed that phenotypes could be hidden in one generation, only to reemerge in subsequent generations.
Recessive traits disappear because recessive alleles can hide out in heterozygotes, allowing them to persist in gene pools and natural selection can only see the phenotype, not the genotype. While harmful recessive alleles will be selected against and it's almost impossible for recessive alleles to completely disappear from a gene pool.

Answer:
There is no cure for herpes but medication can be taken to help it.
Explanation:
This is word for word from medlineplus. org
"Herpes is an infection that is caused by a herpes simplex virus (HSV). Oral herpes causes cold sores around the mouth or face. G*nital herpes affects the genitals, b*ttocks or an*l area. G*nital herpes is a s*xually transmitted disease (STD)."
CDC. gov says
"Herpes infection can cause sores or breaks in the skin or lining of the mouth, v*gina, and rectum. This provides a way for HIV to enter the body. Even without visible sores, having g*nital herpes increases the number of CD4 cells (the cells that HIV targets for entry into the body) found in the lining of the g*nitals."

Cells in the body use oxygen (O2) for cellular respiration. Which is the result of cellular respiration?
A. ATP is consumed, and carbon dioxide (CO2) is released.
B. ATP is consumed, and carbon dioxide (CO2) is absorbed.
C. ATP is produced, and carbon dioxide (CO2) is absorbed.
D. ATP is produced, and carbon dioxide (CO2) is released
The g2 phase is about prepping the cell for mitosis or meiosis where the cells grows some more and produce any of the molecules it still needs before it can divide
