Just as stated and also explained, the correct answer is <span>a long chain of adenine nucleotides is added to the 3' end of mRNA during terminationof transcription. That is the only statement that is true about the polyadenylation mechanism. Hope this is helpful</span>
The right answer is: aorta to smaller systemic arteries to systemic capillaries to systemic veins to right atrium through the tricuspid valve.
The blood pathway is divided into two circuits, both beginning and ending in the heart.
- Systemic circulation (or general circulation, or "circulation")
It begins in the left ventricle, which through an artery distributes oxygenated blood to organs. Then the blood returns to the right heart (right atrium) through the cellar veins.
Each organ has an afferent vessel, supplying blood, and an efferent vessel carrying non-oxygenated blood.
- The pulmonary circulation (or "small circulation")
It begins in the right ventricle, from where the pulmonary artery sends blood without hematosis to a single organ, the lung. The blood is then oxygenated and returns to the left heart (left atrium) by the pulmonary veins.
Answer: Photosynthesis
Explanation: Photosynthesis removes CO2 from the atmosphere and replaces it with O2. Respiration takes O2 from the atmosphere and replaces it with CO2.
I think it’s weather not sure tho sorry it’d it’s wrong
Answer: The correct answer is silent mutation . In this type of mutation there is no change in the phenotype of the individual which means there occurs a mutation where two different amino acid codes for the same protein .There are sequences present in the body where a point mutation occurs but the protein formed is still the same .If you will see the genotype you can easily observe that the amino acid sequence is different but the protein formed is same. Example AAA codes for lysine and the amino acid lysine is formed by AAG .
