Answer:
Bacteria
Explanation:
Bacteria are a group of single celled organisms that are neither plants or animals.
Bacteria lack cell organelles such as the nucleus and the chlorophyll.
They can be found in many environments and most of them are adapted to survive in extreme environments such as hot-springs where the temperatures are extremely high.
Unlike the plant cell wall, bacterial cell wall has a layer of peptidoglucan which determines their shape. Their cytoplasm contains both DNA and RNA.
The bond between one carbon atom and one oxygen atom is polar but due to the fact that there is another oxygen attached to the carbon which has the same electronegativity value as the oxygen on the other side, the effect of polarity is canceled.

is non-polar because the oxygens symmetrically alligned on the opposite sides of the carbon cancel the polarity effect.
If its chemistry:
Hg: Mercury/Transition metal
Ni: Nickel/Transition metal
Ti: Titanium/Transition metal
Out of the following given choices:
Atrophy
Metaplasia
Hypertrophy
<span>The answer is
hypertrophy. Due to the exertion of the heart muscles from increased pumping, the muscles cells enlarge and become bigger than their normal size as an adaptive response. Therefore, ultimately, the heart walls of the heart increase in size (without increase in their numbers as in the case of hyperplasia).</span>
