Which of the following lists includes only components that provide structural support, allow movement, or enable communication b
Deffense [45]

The provided question is incomplete as the options are not given, however on the general knowledge the answer is given:

Answer:

The correct answer is - cytoskeleton, plant cell wall, plasma membrane.

Explanation:

The cytoskeleton is the component that helps in the provided different functions in an organism such as maintaining cell shape, cell signaling by filament systems regulation, and facilitate movement and support.

The plant cell wall also helps in providing the cell to maintain its shape and offers the structural support and cell to cell communication is done by the plasmodesmata that also helps in the movement of the small molecules to transfer from one to another.

The plasma membrane has specific receptors present on them that help in the cell signaling, plasma membrane is semi-permeable and so are able to transport the molecules selectively or with the help of transport protein.

Thus, the correct answer is - cytoskeleton, plant cell wall, plasma membrane.

Select the statements that are true. Question 1 options: CO2 and O2 are water-soluble molecules that diffuse freely across cell
lidiya [134]

Answer:

CO2 and O2 are water-soluble molecules that diffuse freely across cell membranes.

Cells expend energy in the form of ATP hydrolysis so as to maintain ion concentrations that differ from those found outside the cell.

Explanation:

CO2 and O2 are highly soluble molecules in water due to their polarizability and their ability to react with water molecules and form new compounds. CO2 is 30 times more soluble in water than oxygen, which also has a high solubility. This ability allows these two molecules to diffuse freely across cell membranes.

Cells promote hydrolysis, that is, the breakdown of ATP molecules when they need to expend energy for any metabolic process, especially when they need to maintain a balance between ion concentrations inside and outside the cell. This is because ATP is a highly energetic molecule and its breakdown promotes energy for the cell to use in its activities.

What are the functions of punnett squares?
seraphim [82]
Used in biology to figure out the genes that may be transferred from parent to child. Although this square doesn't determine the exact genes, it helps predict the chance of the child having particular genes.
