when a rock falls from outer space all the way to the ground it is called a meteorite.
The correct option is A.
The DNA from one specie differ from the DNA of another specie on the basis of their base ratio. The base ratio refers to the percentage of purine to pyrimidine in a DNA molecule. The base ratio is the one that is responsible for the variability that is observed in chromosomes from different species.
In this case, it is given that the nucleus of the carrot cell is injected into the frog's egg lacking nucleus. In this case, the recipient egg (frog egg) would not be able to produce the carrot. Every species differ from from each other, sometimes, mating between closely related species can produce hybrid offspring, but frog and carrot cannot be combined at all in any aspect.
The carrot is a plant and the frog is an animal. All the physiological processes vary a lot in between plant and the animal. Hence, this growth would not be supported. So, it is impossible to generate a carrot by inserting it's nucleus in the frog's cell.
Cells mainly divide to help living organisms grow.<span />
I think number one is b and number two is D.
I hope this helps!
