Answers:
1. Facilitated diffusion: the process by which some molecules that are not able to pass directly through a cell membrane are able to enter the cell with the aid of transport proteins.
2. Osmosis: the diffusion of water molecules through a selectively permeable membrane.
3. Diffusion: the spreading out of molecules across a cell membrane until to they are equally concentrated.
Step-by-step explanation:
Diffusion is the spontaneous movement of molecules across a membrane from an area of high concentration to one of low concentration gradient.
Osmosis is the diffusion of water molecules across a semipermeable membrane from an area of low solute concentration to one of high solute concentration.
Facilitated transport occurs when molecules cannot diffuse directly through a cell membrane but can diffuse down a concentration gradient through transport channels in the membrane.
<span>The answer that is seemingly true, based on the information given, is: Those that preys on blue crabs would opt to a new prey changing the food web. This occurrence was the reason why some of the organisms die because of the decreased number of blue crabs.And eventually, those that are preyed on by the blue crabs would likely to grow their size.</span>
Answer: During mitosis a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells.
Explanation:
I believe the name for OH- ions is hydroxide.
Answer:
Negative feedback loop
Explanation:
The feedback loop that would allow the blood pressure to go back down to normal would be a negative feedback loop. This type of loop basically causes the body to decrease the effects that are currently taking place while at the same time implementing the opposite effects in order for the system to stabilize itself once again. This can be seen in the depiction below where an effect takes place in the body (positive feedback loop) and the negative feedback loop kicks into re-stabilize the body's system.
