There are 1000 micrometres (um) in a millimetre (mm).
The length of the cell in Figure 1 is 1.5 micrometres (um).
Give the length of the cell in millimetres (mm).
(1 Point)

Answers

Answer: The length of the cell in millimetres is 0.0015.

Explanation:

Given conversion :

[tex]1000\mu m=1mm[/tex]

Thus [tex]1\mu m=\frac{1}{1000}mm=0.001mm[/tex]

Given : Length of the cell = 1.5 micrometers [tex](\mu m)[/tex]

To find: Length of the cell in milllimeters (mm)

Length of the cell in milllimeters (mm) = [tex]1.5\times 0.001mm=0.0015mm[/tex]

The length of the cell in millimetres is 0.0015.

Physical limits on the flow of ______________into and _________of the cell prevent most cells from being too large.

Answers

Answer:

materials/out

Explanation:

Physical limits on the flow of materials into and out of the cell prevent most cells from being too large.

The limitation of the kind and amount of materials that flow into and out of the cell prevents the cell from being too large. The function of selectively allowing materials to enter and leave the cell is carried out by the cell membrane. While being permissible to some materials, it shuts some materials off and, thus, the size of the cell is maintained.

Identify which plant species you have the most of (big bluestem). Say that this is much higher than all the other species, as most only have a few individuals. You can say that there is 6 times as much big bluestem as there is mountain mint (which is the second most common species).

You have to remember that this only shows the species present in a small area of the prairie, so if you repeated this is another area you could have only 1 big bluestem and 100 mountain mint instead.

Just say what you notice, you don't need to be able to explain why this is the case. :)

Which of the following phrases best describes cancer

Answers

Answer:C uncontrolled cell growth caused by mutations in genes that control the cell cycle

Explanation:

Cancer is mutated cell that grew uncontrollably

The phrase that best describes cancer is uncontrolled cell growth caused by mutations in genes that control the cell cycle, hence option C is correct.

Cancer is a broad collection of illnesses that can begin in practically any organ or tissue of the body.

These illnesses are brought on when abnormal cells grow out of control, cross their normal boundaries to infect nearby body parts and/or spread to other organs.

Mutations in the genes that regulate the cell cycle result in uncontrolled cell growth. Cancer cells are unable to recognize or regulate cell division and proliferation. They continue to reproduce as a result.
