The membrane proteins that maintain the shape of the cell membrane, form cell junctions, and allow cells to attach to the extracellular matrix are <u>whole proteins</u>, however, to better understand this answer, we need to know that....

<h3>Membrane proteins</h3>

The plasma membrane contains proteins that are embedded in the lipid bilayer. These perform several functions in the cell, such as:

  • Transport of substances
  • Enzymatic activities
  • and Communication between cells.

The amount of proteins and the types found in the membrane are related to the activity exerted by that cell.

The proteins present in the plasma membrane can be classified into two groups:

  • integral proteins
  • peripheral proteins.

Integral proteins are those that penetrate the phospholipid bilayer. Integral proteins capable of completely crossing the membrane are called transmembrane proteins. These may cross the membrane one or more times.

Peripheral proteins, in turn, are those that do not penetrate the plasma membrane, with only a weak connection to the membrane being observed. Because of this, peripheral proteins can be easily dissociated from the membrane.

With this information, we can conclude that integral proteins are responsible for the shape of the cell membrane, they are embedded in the lipid bilayer.

The bones in a bird are hollow, reducing its weight for flight. This is an example of which characteristic of life?
dimulka [17.4K]

The bones in a bird are hollow, reducing its weight for flight, this is an example of ADAPTATION. The adaptive responses emerge as a consequence of different environmental pressures.

<h3>Adapatation and environment</h3>

Adaptation is an evolutionary process by which organisms adjust to the environment in which they live.

For example, the bones in a bird are hollow because this adaptive feature enables them to fly.

Adaptations are a consequence of the process of natural selection, i.e., the differential survival and reproduction of the fittest organisms.

Hi. Please answer these questions .It's really Urgent.
Agata [3.3K]

1. A caelifera, or more commonly known as the grasshopper belongs in the animal kingdom. Grasshoppers are a leafy green and can be found in a variety of habitats. They can be found in lowland tropical forests or grasslands. Higher classification for the grasshopper would be Orthoptera. Grasshoppers are jumping insects that belong to the arthropod phylum.

Strong, long hind legs that help them jump. This adaptation helps them get away from harm and jump higher.

3. I said some in the first paragraph.

4. Important in grassland ecosystems and play a role in the nutrient cycling.

5. I don’t think there really is anything else.
