Haploid. The only haploid cells are gametes.
The right answer is: controls the movement of substances into and out of cells.
This picture represents a plasma membrane.
The plasma membrane is the membrane that delimits a cell. It separates the cytoplasm from the outside environment.
Special proteins ensure the selective permeability of the membrane (pores), the recognition of chemical signals or carry markers (MHC antigens ...).
The pores are the doors of the membrane. They are macromolecular buildings of protein or glycoprotein nature, sometimes very complex. They are inserted in the bilayer and control exchanges between intracellular and extracellular (with receptors, carriers).
Answer:
Cells that respond to peptide hormones usually do so through a sequence of biochemical reactions involving receptor and kinase activation. In order for cells to respond, it is necessary for first and second messengers to communicate. This is possible because <u>C) G protein acts as the link between first and second messengers </u>.
Explanation:
When the first messengers join the receptor, in the external membrane of the cell, it produces a change in the shape of the receptor that causes the join of the G protein to this structure. The G protein joined to the receptor and the first messenger modulates the activity of the second messengers inside the cell.
The given boundaries are convergent- North America and the Pacific, shearing force, destroys, slab-pull while second one divergent- mid Atlantic ridge, tension force, created, slab-push.
<h3>What are plate tectonic boundaries?</h3>
A plate boundary is a three-dimensional surface where the velocity (speed or direction) of one lithospheric plate relative to the adjacent lithospheric plate changes significantly.

The given boundaries are convergent- North America and the Pacific, shearing force, destroys, slab-pull while second one divergent- mid Atlantic ridge, tension force, created, slab-push.
Thus, these can fill in the table with information about the different types of boundaries.

Phototrophism
There are several starting ingredients that are required for starting the process of photosynthesis. The most important are sunlight, water, carbon dioxide and certain minerals. Sunlight helps in building up the optimum temperature that is required to start the process of photosynthesis. Water is an important raw material that helps to absorb the carbon dioxide from the air.
