Verse 18: Which feature is not an advantage of sexual reproduction over asexual reproduction in animals?
A. Creating many combinations of variations as raw materials for breeding and evolution.
B. Stable maintenance of genetically good traits.
C. Able to adapt to changing environmental conditions.
D. Is a common form of reproduction.
The answer:
Stable maintenance of genetically good traits is not an advantage of sexual reproduction over asexual reproduction because the genetic material is recombined to produce offspring with different genotypes and phenotypes. and different parents, so the good trait will remain unstable.
The answer to choose is: GET
Verse 19: Why is copulation more evolved than asexual reproduction?
A. Because the next generation has a combination of genetic material of different origins, creating genetic diversity, giving rise to many combinations of variations and being able to adapt to changes in the environment. .
B. Because the next generation has genetic homogeneity, it creates the ability to adapt simultaneously to changes in the environment.
C. Because the next generation has a combination of genetic material of different origins, creating genetic diversity, reducing the occurrence of harmful combinations of mutations and enhancing the ability to adapt to change. environmental change.
D. Because the next generation has a combination of genetic material of different origins, creating genetic diversity, there are many beneficial combinations that can adapt to changes in the environment.
The answer:
Mating reproduction (SSHT) is more evolved than asexual reproduction because: Because the next generation has a combination of genetic material of different origins, creating genetic diversity, causing many variables to appear. heterozygous and able to adapt to environmental changes.
B is incorrect because individuals born from sexual reproduction have different phenotypes and genotypes
Meaning C is wrong because it increases combinatorial variation
Idea D is wrong because not all combinatorial variation is beneficial.
The answer to choose is: A
Verse 20: In sexual reproduction, offspring are often diverse due to
A. The process of meiosis produces many types of gametes.
B. The fertilization process produces many types of zygotes.
C. Meiosis and fertilization.
D. Influence of living environment.
The answer:
In sexual reproduction, meiosis produces many types of gametes, and when fertilized, the gametes randomly combine to produce many types of zygotes.
The answer to choose is:
Verse 21: Cross-fertilization is more evolved than self-fertilization because ?
A. Can create a very large number of offspring
B. My life is more diverse
C. Both parents’ bodies take care of the child
D. Egg and sperm meet more easily
The answer:
Cross fertilization: gametes from different organisms combine to form a zygote.
Genetically diverse offspring → adapt well to changing environments
The answer to choose is: GET
Verse 22: In hermaphroditic animals that reproduce by copulation, what is the benefit of maintaining both male and female sex organs?
A. Can switch to self-pollination when necessary
B. Neither beneficial nor harmful
C. Still ensuring reproductive efficiency when population density is low
D. Each organism can produce posterity to maintain the existence of the species
The answer:
Even though hermaphroditic animals have both male and female sex organs, they often cross-fertilize. In adverse conditions, it is difficult to meet another body for cross-fertilization. They can still self-fertilize to create the next generation.
The answer to choose is: A
