Answer:
Both fish and bird embryos exhibit gill slits and a tail.
Explanation:
According to embryology, all vertebrates exhibit similar traits and structures at their embryonic stage. It becomes very difficult to differentiate between the embryos of a fish, and that of a bird, or embryo of a fish, and a human. These traits, however, disappear, as the case may be, as the embryo develops into an adult. For example, in the case of the embryo of a fish, and a bird, both shows gills slits at their respective embryonic stage. However, the gill slits in fish develop into gills, whereas in the case of birds, it disappears as the embryo develops into an adult.
Answer: They will have sterile offspring.
Explanation:
A species can be defined as the number of individuals that can mate with each other in order to produce a fertile offspring, if they fail to do so they belong to different species.
Two of the individuals cannot be considered as same species if they produce a sterile individual.
Sterile individuals cannot give birth to offspring or they cannot reproduce further. So, it can be said so that Texas and Eastern coral snake belong to two different species.
Answer:
The correct answer is ecological isolation.
Explanation:
The condition when two species in spite of living in the same region, exhibits certain characteristics, which inhibits them from mating with each other is termed as reproductive isolation. The obstructions or the causes that prevent them from interbreeding is known as isolating mechanisms.
The given case is an example of ecological isolation and is one of the forms of reproductive isolation. Habitat or ecological isolation refers to the phenomenon in which two species cannot mate with each other as they thrive in two distinct locations. Like as mentioned, two species of garter snakes though coming from the same geographical area cannot interbreed, as one of them is living in the land and the other one in the water.
The correct answers for this question are these:
<span>What could happen if the DNA replication process encounters an error while coding?
- An acquired mutation would occur.
- No noticeable errors would occur to the organism because not all DNA codes for proteins.
- DNA would convert into RNA.
- A mutated trait could be exhibited</span>
