Answer:
D is the answer
Explanation:
Hydraulic facturing, aka fracking, uses toxic chemicals above some regulations which may lead to a leak into water supplies and therefore contaminate it.
It has not much to do with coal, more to do with oil and natural gases
Because of fracking now making it accessible to reach sources in vast number that were previously unacessible, it leads to decreases in gas prices
Hope this helps :)
Answer:
Cells in a large multicellular organism communicate with each other by chemical signals. These signals are passed from one cell to another. To receive and respond to a chemical signal, a cell must have a <u><em>receptor</em></u> for that chemical.
Explanation:
To generate a physiological response, all cells in the body have special proteins called receptors. These receptors are involved in detecting a chemical signal and generating a response. The receptors are specific for different kind of chemical signals. For example, a dopamine receptor will bind a dopamine molecule whereas an insulin receptor will be able to bind an insulin molecule. Apart from chemical signals, some cells might also respond to mechanical signals.
If the temp becomes too great, the enzymes will become denatured as their ionic bonds will change hence altering their shape
Answer:
(a) Phosphatases remove the phosphate from GTP on GTP-binding proteins, turning them off
Explanation:
- A molecular switches are molecule that can be reversibly shifted between two or more stable states.
- The molecules may be shifted between the states in response to environmental stimuli, such as changes in pH, light, temperature, an electric current, micro-environment, or in the presence of ions and other ligands.
Answer:
A
Explanation:
You have to pick something that is negative, something that you would like to have happen.
B is definitely not the answer. You like each other and have respect, that's the bare minimum for a good relationship.
C this one is kind of iffy. If you are playing bridge, that's one thing. If you are dancing too close and drinking, that's another.
D Feeling content. That's practically spells a good marriage.
A If money is a problem, the marriage likely is going to have problems.
