Answer:
diffusion through a selectively permeable membrane
Explanation:
The cell membrane selectively allows certain substances to enter or leave a cell . This implies that cell membranes are selectively permeable; they allow some substances to pass through, but not others.
Direct transport of materials across the cell membrane is often passive. Passive transport does not require energy to occur. Passive transport is the movement of substances from a region of higher concentration to a region of lower concentration. A concentration gradient is always required.
The diffusion through a selectively permeable membrane is an example of passive transport.
The iodine moves into the dialysis tube across the semi permeable cell membrane from a region of higher concentration to a region of lower concentration in response to a concentration gradient.

Answer:
When an object experiences a net force, it will accelerate at a rate determined by its mass
Explanation:
A body at rest is considered to have a zero speed, so any force causing the body to move is an unbalanced force and any force causing the body to slow down is also an unbalanced force. An unbalanced force cause acceleration or deceleration i.e a change in speed

<u>Answer:</u>
<em>Community and ecosystem levels of organization are the main focus areas of Vitor Becker’s work.
</em>
<u>Explanation:</u>
<em>Serra Bonita reserve complex was established by Vitor Becker and his wife Clemira Souza in the Atlantic forest of Brazil.</em> He studied agronomy and forestry and has a Ph.D in entomology.
Becker realized that the Atlantic forests are largely destroyed. After retirement Becker and Souza settled in the <em>Serra Bonita mountain region and using their savings they bought land in the region and converted the area into Serra Bonita reserve complex.
