Answer:
2 weeks to a month
Explanation:
when new skin cells are made, they move from the bottom of the epidermis to the top of the epidermis. This takes about 2 weeks to a month. As the new cells move up, old cells near the top die and rise to the surface of the skin.
The dead cells are what we see on our skin every day.

Which of the following is NOT a member of the cetacean group?
A) porpoise
B)dolphin
C) manatee
D) whale
Answer:
C) manatee
Explanation:
According to Wikipedia, "Cetaceans are aquatic mammals constituting the infraorder Cetacea. Key characteristics are their fully aquatic lifestyle, streamlined body shape, often large size and exclusively carnivorous diet."
The most important thing to note here is the part saying "exclusively carnivorous diet." Manatees are aquatic mammals with a fully aquatic lifestyle and large size, but they are not carnivorous. Manatees feed on water grasses, weeds, and algae, according to National Geographic. So, manatees are not cetaceans.

Our muscle cells sometimes turn to lactic acid fermentation rather than respiration in order to produce energy because they
A.run low on glucose and need something to replace it.
B.produce too much oxygen for our bodies to handle.
C.use up all the pyruvates and must compensate with fermentation.
D.do not receive enough oxygen during strenuous exercise.
Explanation:
D) do not receive enough oxygen during strenuous exercise is right answer.
Muscle cells turn to lactic acid fermentation rather than respiration when they do not receive enough oxygen during strenuous exercise. Thus, the correct option is D.
What is Lactic acid fermentation?Lactic acid fermentation is a metabolic process in which glucose and other sugars are converted into the cellular energy (ATP) and lactic acid. It is a form of anaerobic fermentation reaction which occurs in some of the bacterial cells and animal cells, like muscle cells.
When the muscles are contracting very quickly during strenuous exercise, the oxygen cannot travel fast enough to the muscle cells to keep up with the need of ATP in the muscles. At this point, the muscle fibers switches to a breakdown process which does not require much oxygen (anaerobic respiration).
The muscle cells produce ATP with the lactic acid to give you energy during these difficult physical activities. This condition results when there is not enough oxygen in the body to produce ATP, so the lactic acid fermentation provides acts as a substitute to get ATP without oxygen.
Therefore, the correct option is D.

explain the relationship between stem cells and gene expression
Explanation:
This process your body uses to turn genes on and off is the same one it uses to develop from one cell into the many different cell types that make up your body. Stem cells have the ability to turn into any other type of cell in the body, an ability known as pluripotency.
The relationship between stem cells and gene expression is the process by which the body uses to turn genes on and off is the same one it uses to develop from one cell into the many different cell types that make up your body. Stem cells have the ability to turn into any other type of cell in the body, an ability known as pluripotency.
What is stem cell?Stem cell has been defined as the cell and the raw material of the body and these are the cells which has been specialized the function has been generated. In the right condition of the body or the laboratory, the stem cells has been divided to form the cells known as the daughter cell.
Daughter cell is known as daughter cell because they have to divide again the this quality of division is just the character of daughter cell. Stem cells have the ability to turn into any other type of cell in the body, an ability known as pluripotency.
Therefore, The relationship between stem cells and gene expression is the process by which the body uses to turn genes on and off is the same one it uses to develop from one cell into the many different cell types that make up your body.
