Answer:
Sodium and water move into the cell
Explanation:
Sodium and water move into the cell. This is because
Cellular damage result in failure of the Na+/k+ pump, allowing movement of sodium ions into the cell. This concentration of sodium pulls water in, resulting in hydropic swelling. Cellular damage results in the cell's inability to perform normal metabolic functions because APT decreases and Osmotic finally pressure increases.
This would be because of the melting of icebergs, ice is made of fresh water, that means the water increases in freshness because of the increasing amount of ice melting. It is getting warmer most likely because of global warming, which also contributes to the melting of glaciers
Most types of communication between cells utilize -chemical or electric signals.
Communication is done by the release of chemical signals by the cell thus sending the message. These chemical signals are usually proteins or other molecules that are produced by the sending cell. These signals are released into the extracellular space.
The air puff is the Unconditioned Stimulus
An air puff is "unconditioned" and will naturally require the rabbit to blink
Unconditioned Stimulus - Air Puff
Unconditioned Response - Blinking due to Air Puff
Conditioned Stimulus - Light
Conditioned Response - Blinking due to Light because it is paired with Air Puff
I found the attached image on the internet and it really helps complete this exercise.
First question:
In the presence of an enzyme, the course of the reaction is shown by the
red curve. The necessary energy to make a reaction occur is less when there is an enzyme to help the reaction happen. Enzymes work as catalysts that act over substrates converting them into different molecules in a much accelerated way then it would happen without the enzyme's help, if it would happen at all.
Second question:
The activation energy is represented by
line B. The activation energy is the energy needed to be available for a reaction to happen. If we compare it with line A, which represents the activation energy necessary for a reaction without an enzyme, we can see how much less energy is necessary to dispend when an enzyme is part of the reaction. Line C represents the energy resultant from the reaction.
