Answer:

plant: This Elodea leaf cell exemplifies a typical plant cell. It has a nucleus, and a stiff cell wall which gives the cell its box-like shape. The numerous green chloroplasts allow the cell to make its own food (by photosynthesis).

The central vacuole takes up most of the volume of the cell. It is transparent, but you can see where it's pressing the chloroplasts up against the cell wall, especially at the ends of the cell.

Like animal cells, the cytoplasm of this plant cell is bordered by a cell membrane. The membrane is so thin and transparent that you can't see it, but it is pressed against the inside of the cell wall.

animal :This human cheek cell is a good example of a typical animal cell. It has a prominent nucleus and a flexible cell membrane which gives the cell its irregular, soft-looking shape.

Like most eukaryotic cells, this cell is very large compared to prokaryotic cells. For scale, notice the pair of dark blue bacteria cells sticking to the right edge of the cheek cell. The bacteria are only a fraction of the size of the nucleus, but their tiny size is typical for bacteria.

In response to seasonal changes in temperature, many organisms must alter the composition of their plasma membranes to maintain
aleksandrvk [35]

Answer:

C. a decrease in phospholipid fatty acid side chain length and a decrease in side chain saturation

Explanation:

Temperature is a factor that has a huge impact on cell membrane structure, more precisely its fluidity. So, for example, if temperature increases, the cell membrane becomes more fluid because the fatty acid tails of the phospholipids become less rigid.

How might an individual's own cells lead to false verdicts of guilt.
Gre4nikov [31]

Answer:

Through a circumstance known as "secondary transfer DNA", or "Touch DNA".

Explanation:

Most times when a crime is committed, DNA samples are obtained from surfaces in the scene where the crime was committed. There is a very huge possibility of picking up the DNA of someone who was never at the scene of the crime and this is a result of a condition known as Touch DNA.

Because we touch several objects which can be moved to different locations and touch people who are also always mobile, our DNA cells can find their ways to a crime scene where we had never physically been to. This can lead to false verdicts of guilt.

Suppose that an obligate anaerobe microorganism suffered a mutation resulting in the loss of triose phosphate isomerase activity
masha68 [24]
In deprived of triose phosphate isomerase, only one of the two three-carbon molecules produced by aldolase might be used to produce ATP in which only two molecules of ATP would outcome from the metabolism of each molecule to glucose but two molecules of ATP would still be essential to form fructose 1,6-biphosphate, the sub state for aldolase. The net yield of ATP would be 0, a yield incompatible with life.

Maurinko [17]

The question is incomplete as it does not have the option which are provided in the attachment

Answer:

It is potential energy that can power ATP synthesis

Explanation:

Electron transport chain is considered the most important stage of the cellular respiration as it is the only stage during which a high amount of ATP is produced.

The electron transport through various protein complex where electrons lose its energy and are used to drive the outflow of the proton to the outside of the mitochondrial membrane.

When protons accumulate outside the membrane creates a proton gradient as a result of which the proton needs to enter the cell. The protons enter through the ATP synthase where the potential energy of the proton is used to rotate the rotor and thus ATP is formed from the ADP.

Thus, the selected option is correct.
