Answer:
E. coli is a specie of bacteria that are found in the gut of many animals which helps in maintaining the conditions necessary for the digestion of food.
Explanation:
E. coli is a bacteria which causes no harm to the human or other animals while living in the stomach. In stomach, it helps the digestion of food and make nutrients like vitamin K, which is necessary for the growth of animal body and make the stomach healthy.
The black coat allele will be represented as the capital letter over the lowercase letter in guinea pigs. When crossing, you get 25% for homozygous dominant, 50% for heterozygous dominant, and 25% for homozygous recessive.
Carbon is returned to atmosphere by processes like respiration, decaying and burning. It's absorbed from atmosphere by processes like photosynthesis.
Explanation:
Carbon cycle is a diagramatic approach to explain how the mass of carbon is distributed in our atmosphere, biosphere and earth, and how the cyclic processes run to exchange the carbon mass between themselves.
As far as the pool is concerned, carbon is present as carbon dioxide in the atmosphere. Its from where the carbon is taken from, or is deposited into. Carbon dioxide is given off into atmosphere by means of respiration. Its contributed by each and every living creature which are aerobic and take in oxygen releasing carbon dioxide into the atmosphere. Next process is decaying of organic matters by bacteria and other microorganisms which release carbon dioxide into air. The third process is burning of fuels which releases carbon dioxide and Carbon monoxide into air.
There are several processes by which carbon dioxide is absorbed into the system from atmosphere. One and the most important of them is photosynthesis. This process absorbs carbon dioxide to produce glucose and other organic matters that are then consumed by the whole biosphere as food.

Answer choices:
- Transition
- Transversion
- Nonsense
- Silent
- Missense.
1- This mutant DNA sequence is the result of a ........ mutation. (Transition
or Transversion)
The correct answer is transition mutation.
transverion mutation is when a prymidine base (T) was replaced by annother prymidine base (C).
2- The effect of this base substitution on the amino acid sequence results in a ........ mutation.
The correct answer is a missense mutation.
This mutation is of T to C leads to amino acid subsitution of Alanine (GCG) instead of Valine (GTG).
