Answer:
Yes, extra chromosomes can be received by the tasmanian devil.
Explanation:
Extra chromosomes can be received by the tasmanian devil due to tumor disease in the tasmanian devil. In the beginning the old genome of tasmanian devil has 13 chromosomes but with the tumor disease, it receives one extra chromosome and completed 14 chromosomes. Tumor occurs when the dead cells are not removed from the body and the new ones are formed.
Answer:
No, bottled water cannot go bad.
Explanation:
It is impossible for any sort of water to "expire". But, when in the bottle for to long, the plastic does become dangerous. The bottle begins to leak chemicals into the water. This doesn't make the water toxic, but it can alter the taste of your water.
I think it would be D. because your hypothesis wasn't correct.
Answer:
Mutation, Gene flow/Migration/Immigration of gene and Recombination
Explanation:
For any species there are majorly three sources of genetic variations –
a) Mutation – This leads to change in the genetic code with in the DNA of an organism. Sometimes mutation does not produce any effect on the organism. Mutation can produce both positive and negative impact. Its effect is observed in long run as its rate is slow.
b) Recombination – When an organism undergoes sex, his/her genes recombine with the genes of mating partner. The rate of recombination is faster than the rate of mutation
c) Gene flow /Migration/Immigration of gene – In this gene travel from one set of population to the other. The frequency of gene in the mixed population lies between the original population gene frequency and the migrated or donor population gene frequency
