Introduction:
The reproduction can be defined as the process through which the living organisms produce new offspring. One of the fundamental features of life is reproduction. There are two different forms of reproduction, namely- asexual reproduction and sexual reproduction.
Answer to Problem 1MCQ
Correct answer:
The organisms reproducing asexually have an advantage in unchanging environment. Therefore, option a. is correct.
Explanation of Solution
Reason for the correct statement:
The organisms which reproduce asexually produce identical offspring. The identical offspring are able to survive in the optimal environments. Within the changing environment, the identical offspring is not able to survive. The adverse environment such as temperature fluctuation, disappearance of the prey and the emergence of new
Option a. is given as “that reproduce asexually”.
As, “the unaltered conditions of environment is an advantage for the asexual reproduction”, is the right answer.
Hence, option a. is correct.
Reasons for the incorrect statements:
Option b. is given as “that undergo indirect development”.
In the indirect development, the early part of the life is in the larval form and is not affected by the changing environment. So, it is a wrong answer.
Option c. is given as “in which fertilization occurs internally”.
The internal fertilization is characterized by deposition of the sperms inside the body of female; hence this kind of fertilization is not altered by changing environment. So, it is a wrong answer.
Option d. is given as “that undergo pattern formation”.
In the pattern formation, the shape and the structure of the organism are decided by the genes and are not affected by the changing environment. So, it is a wrong answer.
Hence, options b., c., and d. are incorrect.
The offspring in asexual reproduction carries the similar genetic information and hence they are identical. This kind of reproduction is advantageous in conditions when the environment is not changing.

- External fertilization occurs in which type of environment? a. aquatic b. forested c. savanna d. steppearrow_forwardIs this true or false? a. Fertilization is followed by a cleavage, a period of rapid cell division without growth. b. From the process above, this results in the production of a large number of cells called blastomeres. c. In sexual reproduction, the offspring have the same combinations of genes as their parents. d. Sequential hermaphroditism occurs when an animal is one sex during one phase of its lifecycle and the opposite sex during another phasearrow_forwardHow does the production of sperm differ from the production of eggs? a. Sperm production involves meiosis, whereas egg production involves only mitosis. b. Meiosis during sperm production produces four sperm cells, whereas meiosis during egg production produces only one functional egg cell. c. Sperm are haploid, whereas eggs are diploid. d. Sperm production begins during fetal development, whereas the meiotic process that begins egg production doesn’t begin until pubertyarrow_forward
- If you add a chemical to an egg cell that prevents the fast and slow blocks from occurring but does not prevent the receptor proteins from interacting with sperm recognition proteins, which of the following will happen Group of answer choices A. All sperm would be able to enter the egg b. No sperm would be able to enter the egg c. Polyspermy by the same species would be possible but sperm of different species would be blocked d. Only sperm from different species would be able to enter the eggarrow_forwardC. Why do sea urchins have external fertilization? D. Then why don't the parents take care of the young? E. Because the urchin life involves two or more ecological niches, they are more susceptible to predation and exposure to environmental toxins.

- Which of the following is an advantage of asexual reproduction over sexual reproduction? A. Asexual reproduction leads to offspring with high genetic diversity. B. Asexual reproduction requires a partner. C. The resulting offspring have no genetic diversity. D. Asexual reproduction does not require a partner.arrow_forwardWhich of the following correctly describes hermaphroditism? A. It is an example of sexual reproduction because it involves a male and a female. B. It is an example of asexual reproduction because only one individual needs to be involved. C. It is an example of sexual reproduction because it involves fusion of two gametes. D. It is an example of asexual reproduction because the offspring are genetically identical to the parent.arrow_forwardThe main function of the acrosome reaction is to (a) activate the egg (b) improve sperm motility (c) prevent interspecific fertilization (d) facilitate penetration of the egg coverings by the sperm (e) cause fusion of the sperm and egg pronucleiarrow_forward
