Explanation:

Due to its small size iodine easily passes the membrane and charges glucose, hence iodine is a molecule that is permeable and glucose is impermeable.
Which molecule is permeable and impermeable?Because the tubing was iodine permeable, the contents of the bag became blue-black, indicating the presence of starch.
Glucose also easily flowed through the membrane's pores. After completing Benedict's test on the solutions, both the bag's and the beaker's liquids became brown.
Iodine molecules are tiny enough to pass readily across the membrane, but starch molecules are complex and too huge. Because it passed through the dialysis tube and interacted with the starch, iodine was permeable.
Therefore due to the small size of iodine and its charge with glucose, the permeable molecule is iodine and the impermeable is glucose.

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.

In the northern hemisphere, when does the phytoplankton biomass peak in the polar region? why?
Given what we know about phytoplankton biomass peaks in the polar region of the northern hemisphere, we can confirm that this occurs in the spring.
As the polar regions are tilted away from the sun, days there are short, sometimes these regions even enter month-long periods of darkness. Due to this, sunlight is not always strong enough to penetrate deep into the water.
In the Northern Hemisphere, the phytoplankton biomass peaks in the spring given that during this time the sun is high enough in the sky for sunlight to penetrate deep into the water and provide a food source for the plankton to thrive.

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.

Answer:
where is the chart?
Explanation:
Answer: The beetles with the black color mutation were the fittest organisms in the beetle population because their traits passed on more quickly. The mutation actually became more common than the non-mutated gene. On the other hand, the beetles with the white color mutation died after one generation because the trait was harmful. So, that mutation didn’t pass on to further generations.
