Yes there are cell organisms are divided into each of there own groups
Biosphere, Geosphere (maybe cryosphere), hydrosphere.
I'm not sure, correct me if I'm wrong.
Answer:
The correct answer would be b. Their cells are small and lack a nucleus.
Both archaea and bacteria are prokaryotic organisms that is, they both are devoid of a nucleus and other membrane-bound organelles such as mitochondria, chloroplast et cetera.
They also share a similarity in terms of shape and size of the cells. Both of them are unicellular in nature and can not be seen by naked eyes.
They show variations in their genetic and biochemical ways. For example, archae contains three RNA polymerases whereas bacteria contain a single RNA polymerase.
Their cell wall also show variation in composition. For example, a bacterial cell wall contains peptidoglycans, whereas archae cell wall does not.
Thus, we can say that archae and bacteria are similar in a manner that their cells are small and lack a nucleus.
<span>In human beings the "master switch" that determines whether an individual will become a male is the SRY gene, which is found on the Y chromosome. The sex-determining region Y protein produced from this gene acts as a transcription factor, meaning it attaches to specific regions of DNA and helps control the activity of particular genes.</span>
I think the correct term to complete the thought of the sentence would be "repairing". When you are in the resistance stage of stress, your body is repairing the damage caused in the alarm stage. The resistance stage is a coping mechanism of the brain to be able to cope up with the stress. The body would start to crave or ask for something in order to keep up with the stress. In this stage, blood pressure and hormones are being regulated like cortisol and adrenaline. They may be in high level than the normal but only to a level that is slightly higher. However, this stage does not fully get rid of the stress.
