Through nerves attached to the brain and to the spinal cord. When an action potential traveling down the axon reaches a terminal button, they secrete a chemical called a neurotransmitter.
The brain communicates with the rest of the body through the spinal cord, which runs from the base of the brain all the way down the back. The spinal cord is made up of lots of nerves, and these nerves branch out into more nerves that travel to every part of the body.

Answer:
Attention
Explanation:
Just took the test
A psychologist working from the biological perspective would study all of the following to see how they affect behavior and cognitive processes except Attention. The correct option is A.
Thus, When a psychologist approaches his or her job from a biological standpoint, he or she should not take into account attention as a factor because it is a psychological factor rather than a biological one.
Brain cells, genes, and the nervous system can all be thought of as biological elements.
It can be utilized to analyze how the brain, genes, and nervous system affect cognition and behaviour.
Thus, A psychologist working from the biological perspective would study all of the following to see how they affect behavior and cognitive processes except Attention. The correct option is A.

List reasons you would or would not be concerned about eating genetically modified food
Answer:
Reasons I would be concerned about eating GMO foods:
Explanation:
The FDA declaring them to be "substantially equivalent" to non-GMO foods amid controversy that adequate scientific testing had not been done.
Michael Taylor being in the FDA when "substantial equivalence" was declared. Michael Taylor was a Monsanto employee before taking the position at the FDA.
The technology itself of taking a gene from one species and inserting it into another species (horizontal breeding). While that may be perfectly harmless it is new technology that many believe has not been proven to be safe.
Greater amounts of pesticides being used on GMO crops, which means more pesticides may be getting in our foods.
Crops that are engineered to produce an insecticide in the plant itself possibly having harmful health effects on us. There is some evidence that this may be happening.

what would be the independent, dependent, and control variable to how coral dies? (100 points)
Answer:
in the explanation
Explanation:
The independent variable would be us humans polutling the ocean with oil and other plastics destroying the coral reefs. The dependant variable is an abbrasive species of fish becoming overpopulated and killing all the fish that help the coral grow causing the coral to die. (independant variable basically means humans tampering with it causing the problem. dependent is naturally occuring humans cant control whether a fish overpopluates or not thats natural)

Oxygen sag curves can occur in streams when bacteria break down biodegradable wastes salt and fresh water mix water flows quickly water levels are high water is cool .
What is biodegradable waste?The waste which has been recycled and converted into nutrients for plants as well as crops and for other use are known as biodegradable waste. It has been also known as any organic matter in waste which can be broken down into carbon dioxide, water, methane or simple organic molecules by micro-organisms and other living things.
Composting has been possible with the wastes which can decay by itself, like fruit and vegetable peels, leaves, flowers etc. Non biodegradable wastes will not decay by itself.

Explanation:
a red onion cell has undergone a change, as represented in the diagram below. This change is most likely due to the cell being placed in...
A red onion cell placed in a saline solution will lose water when water moves from the cell to the surrounding hypertonic medium via osmosis, causing the cell to shrivel up.
What is osmosis?The passage of solvent molecules from a lower concentration solution to a higher concentration solution across a semipermeable membrane. It is a passive process that occurs without the use of any energy.
Solvent molecule transfer proceeds from low to high concentration regions until the concentrations on both sides of the membrane are equal.
What are the types of osmosis?An isotonic solution contains the same solute concentration both within and outside the cell.A hypertonic solution has a larger solute concentration outside than inside the cell.A hypotonic solution contains a larger concentration of solutes inside the cell than outside.Thus, we can conclude that when a red onion cell is placed in salt water.
As we can see in the diagram the onion cell shrink which means it is placed in salt water which is a hypertonic solution.
So, option (3) salt water is correct.
