Some organisms mutate and genetically different. Natural selection is when things die off because they have not mutated or adapted to the environmental changes(survival of the fittest) adaptation is necessary to overcome environmental changes. Sorry if I didn't explain this good enough but I hope I helped some
Answer:
30
Explanation:
According to the given information, the diploid chromosome number of tomato is 12. And the diploid chromosome number of potato is 48. Gametes are haploid and contain only one complete set of chromosomes. Therefore, the haploid gametes of tomato would have 6 chromosomes while that of the potato plant would have 24 chromosomes. The fusion of these gametes from tomato and potato would obtain the zygote carrying 6 chromosomes from tomato and 24 chromosomes from potato. Therefore, before doubling, the hybrid would have 6 + 24= 30 chromosomes.
Answer:
Option D, Continents cannot cut through the ocean floor.
Explanation:
It was believed earlier that oceans were the land bridges that used to connect different geologic plates of planet earth earlier, had now sank down and thus there exists no connection between the tectonic plates. Therefore, without any link or connection, continents cannot cut through the ocean floor.
Also as per the Land Bridge Theory , there has been continuous shifting of dry land due to which identical land species on different continents were found.
Hence, option D is correct
Answer: c. maybe, depending on specific traits at organism in cellular levels of both animals
Explanation:
Evolutionary history has to do with the processes through which living organisms evolve from their ancestors to their present generations.
It's quite possible for the fruit fly and the fruit bat to share a common ancestor based on their evolutionary history depending on specific traits at the organism and cellular levels of both animals.
Therefore, the correct option is C.
Answer:
production of gametes is not a function of mitosis
Explanation:
Replacement and regeneration of new cells- Regeneration and replacement of worn-out and damaged tissues is a very important function of mitosis in living organisms. Mitosis helps in the production of identical copies of cells and thus helps in repairing the damaged tissue or replacing the worn-out cells.
