Answer:
c. Active transport
Explanation:
The differences between the different type of a substance's movement through a membrane (phospholipid bilayer) are:
<u>- Passive transport:</u> is the movement of substances across the membrane without needing ATP energy. Encompass facilitated diffusion and osmosis.
<em>Facilitated diffusion:</em> requires a transmembrane protein but the substances move in favor of their concentration gradient (this process doesn't need ATP energy).
<em>Osmosis:</em> when the molecules are not polar they can diffuse through the membrane, as long as they move in favor of their concentration gradient. So this process doesn't need transport proteins neither ATP.
<u>- Active transport:</u> polar molecules or ions require both a transmembrane transport protein and ATP energy when they move from a region of lower concentration to a one higher concentration, meaning, against the concentration gradient.
Answer
Practices that can support a circular economy are;
• Ensuring there is high efficiency in use of available resources
• Cutting down the wastes production
• Practicing maximum recycling of wastes
• Using other business models such as focusing on changing consumer behaviors
Explanation
A circular economy is one that focuses more on changing the consumer behavior of using activities that consumes the scarce resourcesto developing a design from waste system which will have positive outcomes to the society. For example , moving towards embracing renewable energy resources through keeping goods and material in use, continuous generation of natural systems and designing out wastes and pollution.

<span>when the breaking down of acetylcholine is not performed, then symptoms similar to those of poisoning with acetylcholinesterase inhibitors would occur. This would be highly hazardous to the human system as severe poisoning as we all know is very lethal. Even a fetus would not develop with this.</span>
