Explanation:
Many mRNAs have sequences of 50 - 150 nt rich in A and U in the 3' untranslated region. These sequences, called AU-rich elements, are important to regulate mRNA stability, because they bind proteins that target the mRNA for degradation.
When a protein binds to the AU-rich element of the mRNA, the polyA tail can be shortened and/or the 5'cap is removed, promoting mRNA degradation. In addition, the AU-rich elements in some mRNAs have been shown to inhibit protein translation.
The mRNA of the overexpressing cell line is about 200nt shorter than the normal cell line; this could mean that it has a deletion in the 3'UTR comprising an AU-rich element. If this is missing, the mRNA will have an extended half-life (because it won't be targeted for degradation) or it will be translated more. As a result, the protein expression will be increased.
Deposition from flow into a lake or an ocean
A delta is a feature of a river that occurs at its mouth whereby the river tends to drains into a water body (ocean or lake) through several drainages.
Explanation:
As a river approaches and drains into a water body, like a lake or ocean, it deposits a lot of sediments that it collected upstream. The high gradient upstream gives the river a high energy flow enabling it to have high erosion power and it can carry lots of sediments. The geographical gradient lowers closer to the mouth of the river and much of the sediments settle down due to the low speed and energy of the river flow at this stage. Over years, the sediment accumulates over a large area and the river has to find several channels to drain into the ocean or lake. This forms a delta.

Answer:
1aNeon
b. positive charge.
c. As atomic number is equal to no. of protons and no. of electron and atomic number 10 element is Neon.
Positive charge as it have lost one of it's electron.
Atomic number = no. of protons = no. of electron and since electron can be shared loose or gain to develop charge it have loose on electron.
2a. 4 protons
b. 2 electrons
c. In question 2(a) the atomic number of Be is 4 so it would have four protons.
And as for question (b) it is said it have 2 charge which means positive charge would mean that it have lost 2 electrons and is left with 2 electrons which fulfill it's duplet configuration.
