Answer:
<em>Plants </em>are generally considered the best indicators of the level of succession in an ecosystem. Explain how you got your answer.
Explanation:
Plants are generally forms the basis of life in any environment, other organism strictly depends for survival and continuation of life as they are the only autotrophs in the food chain. The best indicator of the level of succession in an ecosystem remains the plant
Answer:
The Mitral/Bicuspid Valve
Explanation:
The heart is composed of 4 chambers: left and right atria, and left and right ventricles. The “right heart” (right atrium and ventricle) receives deoxygenated blood from the systemic circulation through the Vena Cava, and impels this blood towards the lungs through the Pulmonary Arteries where it will be oxygenated. The “left heart” (left atrium and left ventricle) receives oxygenated blood from the pulmonary circulation through the Pulmonary veins and impels this blood towards the systemic circulation through the Aorta artery.
The systemic and pulmonary circuits work in series, and maintaining the unidirectional course of the blood flow is very important. This can be done by the presence of fibrous valves that are present between the atrium and the ventricles, and in between the ventricles and the Pulmonary/Aorta artery.
The location of these structures are as follows:
Systemic circulation ⇒ Right Atrium → [Tricuspid Valve] → Right Ventricle → [Pulmonary Valve] → Pulmonary Artery ⇒ Pulmonary circulation
Pulmonary circulation ⇒ Left Atrium → [Mitral/Bicuspid Valve] → Left Ventricle → [Aortic Valve] → Aorta ⇒ Systemic circulation
OK my friend basically pleiotropy would be when one gene affects multiple traits so the answer will be option D.
Answer: The correct answer is- Amino acid.
Codon represents a unit of genetic code, which determines a specific amino acid.
It is a sequence of three nucleotides that are present in DNA/RNA sequence and codes for a specific amino acid ( like UUU codes for phenylalanine) during the process of translation. Codon also generates a start signal or stop signal during protein synthesis ( such as AUG is a start codon and UGA is a stop codon)
