Unchanging environments are advantageous to organisms
a. | that reproduce asexually |
b. | that undergo indirect development. |
c. | in which fertilization occurs internally. |
d. | that undergo pattern formation. |
Introduction:
Reproduction is the process of producing new organisms from the parent organism. It is of two types, sexual and asexual reproduction. In sexual reproduction, two parents are involved. However, in asexual reproduction, a single parent produces its offsprings.
Answer to Problem 1MCQ
Correct answer:
The unchanging environment is favorable for asexually reproducing organisms. Hence, the correct answer is option a..
Explanation of Solution
Reason for correct answer:
Option a. is given as “that reproduce asexually.”
The asexual reproducing organisms do not show any effect of changing the environment. Under constant environmental conditions, the sexual ability of asexually reproducing organisms remains the same.
Reason for incorrect answer:
Option b. is given as, “that undergo indirect development.”
Organisms that undergo indirect development show an adverse effect of unchanging environment. This is because they complete each of their life stages in the different host and every host has different environmental conditions. Hence, option b. is incorrect.
Option c. is given as, “in which fertilization occurs internally.”
Internal fertilization occurs inside the female body. So, these organisms do not show any effect on the changing environment. Hence, option c. is incorrect.
Option d. is given as, “that undergo pattern formation.”
Pattern formation is the process of forming body structure and the overall shape of an animal. It has no effect on the environment. Hence, option d. is incorrect.
Hence, the options b., c., and d. are incorrect.
Organisms that reproduce asexually do not show any effect of changing the environment. They can reproduce with the same ability in the unchanging environment. Thus, the correct option is a.
