The answer would be D.
The mutation would cause a(in most cases) new and different polypeptide(protein) to be made so it can cause a different trait. For example a new eye color in fruit fly with mutated dna.
I believe that most mature soils have three soil horizons. That is Horizon A, Horizon B, and Horizon C. Horizon A, also called the top soil contains a mixture of mineral matter and organic matter, as well as many insects, fungi, and microorganisms. Horizon B, also called the sub soil, contains fine clay particles washed out of horizon A. Horizon C contains partially weathered parent material.
"The differences in pre-mRNA splicing that results in an altered pattern of exon inclusion" is most likely to have contributed to this phenomenon.
<u>Option: C</u>
<u>Explanation:</u>
The expression of the eukaryotic gene requires several stages and can be regulated by several of them. Different genes are controlled at different locations and it is not unusual for a gene to be controlled at multiple steps, especially a significant or powerful one.
- In accessibility of Chromatin the chromatin structure includes DNA and can be regulated by its assembling proteins. More free or 'relaxed' chromatin allows a gene more transcriptible.
- For many genes transcription is a key regulatory point. Its factor protein sets bind to unique DNA sequences within or near to a gene and encourage or suppress its transcription into an RNA.
- It is possible to control the splicing, capping, and attaching a poly-A tail to an RNA molecule, and thus exit the nucleus. Specific mRNAs might be produced by alternative splicing from the same pre-mRNA.
1. Drought period - in time periods where there is more precipitation there is more water availability, and when there's not there isn't.
Floods - when there are floods there is much more water available.
Population density - in places with more population there is a greater need for water supply, while in places where there is lesser people, the water supply can be smaller.
2. The land, air, and water are heated each day by the sunlight. The heat produced by the sun that hits the earth as the earth rotates is then part kept by the atmosphere that doesn't permeate all of that heating energy.
3. By evaporation. As the sun heats the ocean, there is evaporation. As the ocean moves around with its tides there is also loss of water to the air. Also by the waves and winds there is water that's lost to the air.
4. Part of that vapour will be reabsorbed by the ocean because it cools and precipitates into the ocean. Other part of it is taken with the wind to land or to upper spheres of the atmosphere.
5. Part is reabsorbed but other part isn't. The other part is taken by the wind. As a gradient, there is less water in the air then in the ocean, keeping it above the ocean.
6. There is more water in the oceans then on the land. Water remains in the air on average about 9-10 days.
7. --------
8. An average American family uses about 300 gallons of water.
9. About 22%.
10. About 27%.
