<h2>ANSWER:</h2>

Simple diffusion is passive but facilitated diffusion is an active process

<h2>EXPLANATION:</h2>

In facilitated diffusion, molecules just move by the help of a protein in the membrane. Simple diffusion is passive while facilitated diffusion is an active process that utilizes energy. Simple diffusion needs molecules to move within special doorways in the cell membrane.

Check Your Understanding<br> Question: What is an adaptation?

AleksandrR [38]

Answer:

an adaptation can be defined as an inherited trait which confers an evolutionary advantage to the organism in a certain environment

Explanation:

An adaptation, also known as an evolutionary adaptation, can be defined as any physiological and/or morphological inherited trait related to the improved evolutionary fitness of one organism in a particular environment. An adaptation improves the chances of survival and reproduction in a certain environment, thereby organisms carrying the adaptation have more chances to produce descendants and pass their genes to the next generation. Some classical examples of evolutionary adaptations include the long necks of giraffes that help them to eat leaves at the top of trees, light bones of flying birds, etc.

Blood flows through an artery that is partially blocked. as the blood moves from the wider region into the narrow region, alternately increases and then decreases.

<h3>What is the purpose of blood flow in heart?</h3>

The removal of positive charge by electrochemical gradients causes the membrane potential of the cell to shift more strongly in the direction of the equilibrium potential for potassium.

The membrane would become more negative as potassium permeability through the membrane increased. Given that potassium is a positively-charged ion and that the intracellular environment has a net negative charge, enhancing the membrane's permeability would result in a more negative membrane.

For instance, the amplitude of the potassium concentration gradient across the myocyte decreases as the external potassium level rises, lowering the resting membrane potential.
