It allows polar and charged molecules, such as carbohydrates, amino acids, nucleosides, and ions, to cross the plasma membrane. Two classes of proteins that mediate facilitated diffusion are generally distinguished: carrier proteins and channel proteins. The plasma membrane needs these molecules in order for the cells and the body to function

Hello?? Can anyone help me??! PLEASE

Answer:

The temperature is staying the same. In the graph when it shows solid/liquid and liquid/gas, the temperature stays the same until it changes. This is because it reached it's melting point/vaporizing point. For example, a solid gets heated up, it then reaches it's melting point but it can't go higher than that because it isn't fully a liquid yet, once it's a liquid it will then continue to rise in temperature.

I don't think I put enough detail into that explanation but I hope this helps your problem.

vova2212 [387]

Identical and obviously duplicated gene sequences have gotten from one chromosome to another by chromosomal translocation.

In terms of genetics, a translocation takes place when chromosome fragments and the (often two) fragmented portions reassociate with other chromosomes. For the diagnosis of several genetic diseases and syndromes, the finding of chromosomal translocations can be crucial.

Multigene families are groups of related or identical genes that have developed by gene duplication. It is thought that a single ancestral gene was duplicated and varied to create multigene families. The multigene families that code for actins, hemoglobins, immunoglobulins, tubulins, interferons, histones, etc. are a few examples.
