Answer:
The statement is true.
Explanation:
The myocardium is the muscle tissue of the heart, a muscle responsible for pumping blood through the circulatory system through contraction. It receives a part of the large volume of blood that passes through the atria and ventricles. A system of arteries and veins (coronary circulation) provides the myocardium with oxygen-rich blood and allows the return of venous or oxygen-poor blood to the right atrium. The right coronary artery and the left coronary artery are the branches of the aorta responsible for the blood supply.
Answer:
Translation occurs in a structure called the ribosome, which is a factory for the synthesis of proteins. ... Translation of an mRNA molecule by the ribosome occurs in three stages: initiation, elongation, and termination. During initiation, the small ribosomal subunit binds to the start of the mRNA sequence.
Explanation:
That will be once every year
The end products of electron transport chain are:
Water
Adenosine triphosphate (ATP)
Explanation:
- Most of the free energy released during the oxidation of glucose to CO₂ is retained in the reduced co-enzyme NADH and FADH₂, generated during the kreb's cycle.
- Electron are released from these co-enzymes and are eventually transferred to an oxygen molecule to form water.
- These transfer of electron from co-enzymes to oxygen molecule occurs through a series of protein complexes in the mitochondrial membrane. And the process is termed as Electron Transport Chain.
- The large amount of free energy is released during the oxidation of NADH and FADH₂ is used in the production of ATP
The correct answer is option C
The demand for a better life increased the pollution in the society. The increased pollution in the environment led to many health problems.
The Nuclear power plant creates radioactivity and thermal pollution.
The water used in the nuclear power plants is very warm and causes thermal pollution as it is released into water bodies.
The nuclear power plant uses radioactive substances like uranium and the waste that is left is radioactive waste.
