Answer:

The correct options are:

A-C-E-G-I

A-C-E-I

A-C-G-I

Explanation:

Alternative splicing of RNA produces many mRNA strands from primary RNA transcript. When alternative splicing of RNA occurs, all the introns and some exons are removed. The removal of these exons produces different mRNA strands which are then translated into diffident kinds of proteins. Alternative splicing of RNA can highly increase the number of new produced proteins from same gene.

If a cell with 12 chromosomes undergoes mitosis, how many daughter cells result and what is the chromosome number in each daught
VMariaS [17]
Mitosis is a kind of cell division that produces 2 daughter cells that is genetically identical to both the other daughter and the parent cell.

By the word genetically identical, it means that they have the same number of chromosomes.

This process starts by a parent cell doubling their chromosomes, then, it divides, and therefore each daughter cells receive the original number of chromosomes.

Therefore, the answer to this question is 2 cells, 12 chromosomes each.

Describe three observations an astronaut might make while viewing Russia at night.(Site 1)
serious [3.7K]
<span>One observation would be the physical size of Russia compared to other countries, despite a lack of visible borders from space. In addition, part of Russia's outline would likely be obscured by the various clouds and objects in the stratosphere; this would allow the astronaut to view potential cloud and weather patterns on earth. Also, an astronaut could see outlines of Russia's geography such as mountain ranges.</span>

Why is chlorophyll not able to capture the energy in green light​
mariarad [96]

All plants have chlorophyll-a which blocks(reflects) green light and absorbs red and blue wavelengths. It seems like it would be more efficient for plants to absorb green light since energy is most powerful from the sun through green wavelengths. However, the chlorophyll-a in chloroplasts actually defend the plant from harmful damage of the TREMENDOUS amount of power from the sun transmitted in green wavelengths.

SO CHLOROPHYLL-A PROTECTS PLANTS FROM TOO MUCH ENERGY IN GREEN LIGHT.
