If fertilizers  enter the St.Johns river they will result in nutrient overload, or eutrophication and harming the ecosystem of the river. The river will exceed its assimilative capacity for nitrogen and phosphorus. this will <span>deplete oxygen in the water needed by fish and reduce light that is essential to submerged vegetation. </span>

Describe the effects of NE and Ach on contractile force that you observed today. Given your knowledge of sympathetic and parasym
Afina-wow [57]

Answer:

The answer is Norepinephrine.

Explanation:

Acetylcholine (Ach) and Norepinephrine (NE) are both chemical substances (neurotransmitters) released primarily by nerve cells and they affect different parts and systems of the body. Acetylcholine mostly targets the muscles and the brain and it is a part of the parasymphatetic nervous system whereas norepinephrine targets the whole body and has an effect that leads to the contraction of muscles and the increase of the heart rate. Norepinephrine is a part of the symphatetic nervous system.

Since the symphatetic nervous system is responsible for the crucial "fight-or-flight" response of our body, it has a more dramatic effect on the muscle contraction. Norepinephrine, being a part of the symphatetic nervous system, should result in a more drastic change in contractile force.

I hope this answer helps.

Number the steps of the binary fission process in correct order
kari74 [83]

Step 1:

The bacterium cell must copy its DNA so the new cells will have DNA. DNA or, deoxyribonucleic acid, has all of the information the bacterium will need to survive, so it is important it gets copied. The DNA is tightly wound so it is in a neat package called a chromosome.

Steps 2 and 3:

The bacterium now grows larger. This allows for some separation between the two DNA copies that are inside the cell. A division develops in the middle of the bacterium. This division eventually completely divides the bacterium in half. This is called cytokinesis.

Step 4:

Each cell is now called a daughter cell and they separate.

The steps of binary fission

binary fission

Binary fission results in two identical daughter cells. This is a type of asexual reproduction, or creating genetically identical offspring. If humans were able to reproduce using binary fission, it would look something like this: your mother or father would grow larger, and inside all of his or her DNA would be copied. Eventually your parent would split in half creating an identical clone.
