converting food into smaller molecules
Answer: B
WHY?
Deletion mutation may cause a shift of base sequence, causing the reading frames for base sequence to change during translation. This may affect the type of amino acid it the original base sequence codes for, resulting in a change in amino acid sequence in the polypeptide translated. Therefore, affecting the whole protein itself. There may be wrong amino acids that prevents vital bonds like disulfide bridges to form, resulting in a huge change in 3 dimensional conformation of the protein. A point mutation may result in a gene sequence being edited. However, only the target sequence is being mutated. The rest of the gene sequences are left untouched. Therefore, the impact is localised. This ensures that even though a few wrong amino acids may be in the polyleptide, most of the bonds that are crucial for the correct 3 dimensional conformation is still present, therefore, lesser defects will be resulted due to point mutation as compared to deletion mutation.
Answer:
C. habitat isolation; temporal isolation; behavioral isolation; mechanical isolation; gamete isolation.
Explanation:
Reproductive Barriers may be of any type which includes habitat isolation; temporal isolation; behavioral isolation; mechanical isolation; gamete isolation. All these examples are categorized under prezygotic barriers.
Habitat isolation: It occurs in case of allopatric speciation, initially all the members of a species can mate with each other but later on due to geographic barriers like due to a rift, their habitat separates and they cannot mate with each other and later on they evolve as separate species.
Temporal isolation: In temporal isolation, reproductive barrier is different time/season of breeding like American toads and Fowler's toad both are closely related and have potential to mate but due to different mating season they are unable to mate with each other. American toads mate during summers while Fowler's toad mate during late summers.
Behavioral isolation: When the members of two closely related species behave and respond to different mating behavior, it is known as behavioral isolation. For example breeding calls.
Mechanical isolation: Mechanical isolation occurs because of structural or chemical barriers. For example: when the shape of pollinator does not match with that of flower then the male gametes will not be able to reach to the egg cell.
Gamete isolation: When the gametes are unable to fuse due to any reason like less mobility of sperm in the female reproductive tract.
