Aleks [24]2 years ago

They have both hydrophilic and hydrophobic regions.

<h3>Why can lipids pass through the cell membrane easily?</h3>

Permeability refers to the ease with which molecules cross biological membranes. Because of the chemical and structural nature of the phospholipid bilayer (hydrophobic core), only lipid-soluble molecules and some small molecules are able to freely pass through the lipid bilayer.

<h3>What materials can easily diffuse through the lipid bilayer and why?</h3>

The structure of the lipid bilayer allows small, uncharged substances such as oxygen and carbon dioxide, and hydrophobic molecules such as lipids, to pass through the cell membrane, down their concentration gradient, by simple diffusion.

What does the vertical axis on the population pyramid represent?What does the vertical axis on the population pyramid represent?
xenn [34]
In a population pyramid, the size of the population under investigation is depicted on the horizontal axis, and age is aligned on the vertical axis. The result is a series of bars stacked on top of one another, each representing an age category (typically in 5-year age groups), with the youngest age group represented by the bottom bar and the oldest age group by the uppermost bar. The horizontal length of each bar represents the number of individuals in the specific age group for the population depicted.
