Answer:
Bacteria under successive rounds of selection may acquire genetic resistance to the treatment with mutagenic compounds including ethyl methanesulfonate (EMS).
Explanation:
Artificial selection is a process known to generate resistance of the organisms under treatment. For example, this type of selection has been reported to generate resistance to the treatment with different chemical compounds including mutagenic chemical compounds (in this case EMS), antibiotic drugs, etc.
Answer: chromatin
Explanation:
What is uncoiled, stringy DNA called? It is called chromatin. How many pieces of chromatin does a human diploid cell have? Human diploid cells have 46 pieces of chromatin.
Answer:
The correct answer is D. fitness
Explanation:
The ability of an organism to survive up to reproductive age and produce its offspring is called biological fitness. The fitness of any individual can be measured by the genetic contribution of that individual into the next generation.
This means that the higher the number of offspring produced by any individual higher would be its biological fitness. By averaging the fitness of population members the fitness of a population can be calculated. So fitness is the correct answer.
The cell nucleus, could be up there as the nuclei
An oxygen atom alone will have 6 valence electrons (outermost electrons). A hydrogen atom each has 1 electron in its outermost shell to share with the oxygen. For oxygen to have a filled outer shell, it will take one electron from each of the two hydrogens into it's outer shell. This means, the number of electrons in its valence shell will be the original amount of electrons oxygen has by itself plus 1 electron from each hydrogen atom. This will form a water molecule
