Introduction:
Sexual reproduction involves formation of new individuals when genetic information from two different sexes combines to produce a genetically different offspring. As, a result the resulting offspring is genetically variable from both the parents.
Answer to Problem 1MCQ
Correct answer:
The new combinations associated with sexual reproduction in plants are the result of meiosis. Hence, the correct answer is options c.
Explanation of Solution
Reason for correct answer:
Option c. is given as, “meiosis.”
Sexual reproduction involves mixing of the genes of both the parents and this is made possible by the process of meiosis, which causes the rearrangement of genes and reduces the number of chromosomes, which is then restored to a complete diploid number after fertilization. Hence, option c. is correct.
Hence, the option d. is correct
Reason for incorrect answers:
Option a. is given as, “mitosis.”
Mitosis is a form of cell division which produces genetically identical clones as parent in the process of asexual reproduction. Hence, option a. is incorrect.
Option b. is given as, “cloning.”
Cloning is making identical copies. It does not involve mixing of genetic information required for sexual reproduction. Hence, option b. is incorrect.
Option d. is given as, “both b and c are correct.”
New gene combinations are not made through cloning; it is only made through meiosis. Hence, option c. is incorrect.
Hence, the options a., b., and d. are incorrect.
Meiosis causes formation of new gene combinations that is associated with sexual reproduction in plants. Thus, the correct option is c.

The article could be about the pathogen itself, the disease process related to the pathogen, the immune response to the pathogen, vaccines or treatments that affect the pathogen, or other biology-related study about the pathogen. I recommend that you choose a pathogen that is currently interesting to researchers, so that you will be able to find plenty of articles about it. Avoid choosing a historical disease that no longer circulates. List 3 possible pathogens or diseases that you might want to do for your group project.arrow_forwardnot use ai pleasearrow_forward

In oxidative phosphorylation 3 ATP are produced from every one NADH molecule. In respiration, every glucose molecule produces 10 NADH molecules.
