The correct answer is (b) Jupiter has mass less than that of sun which cannot generate enough pressure which can start hydrogen fusion. Jupiter has similar composition as both are entirely made up of hydrogen and helium. They both differ in the core and mass. The mass of Jupiter is so small as compared that it would not be able to generate enough pressure to start hydrogen fusion. Jupiter's core is made of metallic hydrogen and the core of sun is so hot that the hydrogen splits into electrons and protons. This generates hydrogen fusion.
Thus, Sun a star and Jupiter is not a star.
<u>Answer</u>:
It makes the kinetics of the complex so rapid as to prevent it from being the rate-limiting step(s) of a pathway is not true regarding substrate channelling
<u>Explanation</u>:
Substrate channelling is the transfer of transitional metabolic products of one enzyme straightly to other enzyme or any active site without its release into solution.The metabolic pathway can be made more rapid and also efficient than it would actually be through channelling if enzymes could have been randomly designed. It occurs in many ways like in pyruvate dehydrogenase complex may be tryptophan synthase or can be dihydrofolate reductase thymidylate synthase.
Severe burns can destroy muscle tissue and damage the kidneys
The correct answer is Phloem
Explanation:
Phloem is a transport tissue of vascular plants. It is used for transport of food and nutrients, so sugar is definitively brought by phloem.Other choices cannot be right because collenchyma and parenchyma are ground tissues, while xylem is the carrier tissue similar to phloem but worked for a conveyor of water and minerals.
Answer:
Catabolic processes break down material and transforms fuels into cellular energy, whereas anabolic processes require energy for biosynthesis.
Explanation:
Metabolism is a constructive and destructive process which occurs in the body of living organisms. There are two types of metabolism i. e. catabolism and anabolism. Catabolism is a destructive process in which food molecules are broken down into simpler substances for the production of energy while anabolism used this energy for the formation of new cells and muscles etc.
