The right answer is 3 nucleotide bases.
5'-CGGCACCGCCCTAAGTCTCT-3'
5'-AGGCACCGCCCTAAGTCTAC-3'
It would be necessary first to align the two sequences side by side so as to be able to compare them, and they should also be in the same direction.
The nucleotides marked in bold are the nucleotides that differ between standard and O. Kisutch.
These nucleotide changes are necessarily due to substitution mutations that exchanged one nucleotide for another in the same location.
Food chains model energy flow through an ecosystem. Producers pump energy into an ecosystem from an environmental source, and this energy is then passed from one organism to the next.
This produces several negative effects on the biodiversity of the river ecosystem.
<u>Explanation:</u>
The Susquehanna river is polluted by the excess release of nutrients like phosphorous and nitrogen from agricultural land and sewage treatment plants. This can adversely affect the health of the river. The excess of nutrients will accelerate the growth of algae in the river.
The dead algae that settle at the bottom of the river decay by consuming the oxygen present in the river. This will reduce the amount of dissolved oxygen in the river and affect aquatic life.
Thick algal growth partially prevents the penetration of sunlight into the water and this affects the growth of submerged plants which are food to the fish.
A because osmosis will act to balance the concentrations of water inside and outside the cell. As this happens, sugar outside the cell will dissolve into the water and be moved across the cell membrane with it into the cell. This continues until the concentrations are equal.
