Answer:
Fracking has adverse effect on water resources. The most potent danger lies in the fact that the fracking fluid may flow back to the surface and contaminate water.The fracking fluid contains toxins and carcinogen along with sand. This fluid when mixes with fresh water resources by any chance will prove hazardous. And hence degrade the availability and quality of potable water.
Explanation:
- Fracking or hydraulic fracturing is a technique used by industries to bring out oil and gas from the rock reservoirs.
- In this process a fluid known as fracking fluid is forcefully injected into the rock so that a fissure can be created and the rock breaks open due to the extreme pressure of the fluid.
- Fracking fluid can prove itself to be a environmental Hazard , because of the toxic chemicals and carcinogens mixed in it.
I think Metamorphism changes only the shape of rocks. I'm not a 100% sure but correct me if I wrong
Answer: Option B) determine the sequence of amino acids in a protein
Explanation:
The messenger RNA (mRNA) molecule carries a seqence of bases that is complimentary to the template strand of DNA.
Hence, instead of thymine, uracil nucleotides exists in the mRNA molecule; while the mRNA is transcribed to the corresponding amino acids.
For instance: a template strand of ACC CGG is transcibed as UGG GCC on mRNA, and translated to an amino acid sequence of Tryptophan and Alanine.
Answer:
it is b
Explanation:
you can make a chart about it and/or serch it up on google
<span>During the luteal phase of the ovarian cycle, progesterone secretion peaks and estrogen levels decrease. along with these changes, there is a corresponding increase in a woman's basal body temperature. In this phenomenon, i</span>t is not the increase in progesterone, but the decrease in estrogen that may signal an increase in overall body temperature. This is because the decrease in estrogen reduces the negative feedback signal to the hypothalamus, the thermoregulator for the body. The result is an increase in overall basal body temperature.
