Helga [31]
The very function, or job of CELL MEMBRANES is to protect the cell from it's surroundings, or in other words, to keep it safe. It controls the movement of substances in and out of cells and organelles, like a guard watching for suspicious activity and protecting something.

The cell membrane itself is a thin, flexible layer around the cells of all living things. It separates the inside of the cells from the outside of the cells.

It touches the offspring and not the zebra itself because only the sex cells which gives spermatozoids or ovules) are touched.
The main symptom of hypoproteinemia is swelling of the legs, face and other parts of the body due to fluid accumulation loss of muscle mass.</span>

Choose the CORRECT statement concerning the cell membrane lipid molecules
VashaNatasha [74]

Answer:

The correct statement concerning the cell membrane lipid molecules is that "energy is not expended during diffusion" (Option d)

Explanation:

Biological membranes are formed by two lipidic layers arranged with their hydrophilic polar heads facing the exterior and the interior of the cells, and their hydrophobic tails against each other. Membranes are fluid, which means that molecules that form it have the capability to move through it.  

Lipids can easily change places with other neighbor lipids by <u>lateral diffusion</u> in the same layer. This is passive diffusion, which means that it does not need energy to happen.

Lipids can also diffuse transversally to the other layer, but this kind of movement is not as easy as lateral diffusion.

There are also other lipidic movements as rotational diffusion that imply the rotation of the molecule.

Through this lipidic bilayer, there is also a passive transport of some particles from one side of the cell to the other which happens because of concentration differences.

Suggest an intracellular regulatory molecule (from your text) that growth factors might stimulate to control cell division. Plea
vlabodo [156]

Answer:

E2F transcription factors  

Explanation:

The E2F transcription factors (TFs) encode intracellular factors associated with the control of the cell cycle. E2F are TFs that bind to promoter consensus sequences in order to activate transcription. These TFs control the expression of target genes involved in cell proliferation including, among others, genes for DNA replication and mitotic activation. Moreover, the E2F proteins also may act as a link between cell fate and the cell cycle. The retinoblastoma (Rb) is a protein that modulates the activity of the E2F family of TFs, and it has been shown that the Rb/E2F pathway is a key molecular mechanism associated with cell proliferation.
