Answer: Cell number one is an hypotonic solution, cell number two is an isotonic solution, and cell three is an hypertonic solution.
Explanation:
Cell number one which is a 98% water content is added the 100% water solution, water moves from low to high concentration. Therefore, the water moves from the solution into the cell, which is hypotonic.
Cell number two which is a 98% water content added with a 98% water solution. These two solutions are equal to one another, so the water does not move. This is isotonic.
Cell number three which is a 98% water content added with a 80% water solution. Water moves from high to low concentrations, so water moves from the cell to the solution. The water leaves the cell, which is an hypertonic.
The given statement is TRUE.
A positive feedback loop causes a self amplifying cycle in which a physiological change leads to even greater change in the same direction.
A negative feedback loop is a process in which the body senses a change, and activates mechanisms to reverse that change.
What is a positive feedback loop?
In nature, a positive feedback loop happens when the outcome of a reaction increases that reaction. A positive feedback loop pushes a system further away from the equilibrium goal if we consider a system in homeostasis. It takes place when something needs to happen quickly and does this by enhancing the effects of a product or event.
<u>Example</u> : Ripening of fruit
In nature, there is a strange phenomenon when a tree or bush may suddenly and silently begin to ripen all of its fruit or veggies. This is the first instance of a beneficial biological feedback loop we've found. If we see an apple tree with many apples, they all appear to ripen over night, going from being unripe to ripe to overripe. The first apple to ripen will mark the start of this. It releases ethylene (C2H4) via its skin when it is ripe. The apples nearby ripen as a result of being exposed to this gas. As soon as they are ripe, they too begin to generate ethylene, which continues to ripen the rest of the tree in a manner akin to a wave.

I think the answer is -
when the body experiences a drop in temperature it forces the water molecules to move faster in order to break the hydrogen bonds and release energy as heat.
hope this helps you.
Answer:
Altered states of consciousness, also referred to as non-ordinary states, contain different mental conditions in which the brain is aware but not in its normal wakeful condition like meditation etc.
Explanation:
Altered states of consciousness, also referred to as non-ordinary states, contain different mental conditions in which the brain is aware but not in its normal wakeful condition like meditation etc.
Altered states can happen from yoga class to a child's birth anywhere. They enable everyone to see our experiences and oneself with a wider lens and from different points of view than the normal mind.
The benefit associated with the meditation practice are:
1) improved attention
2) faster recovering from being sad
3) reduced stress hormones
4) reduced blood pressure
As each order of consumers eat other organisms, energy that transfers decreases.
