Answer:
E) Both Bacillus and Clostridium.
Explanation:
Bacterial endospores production is part of its survival mechanism. Bacteria produces these highly resistant spores that lies dormant in vegetative state, used during unfavourable and stressful environmental conditions. They are produced by gram positive bacteria such as Bacillus and Clostridium, and can lay dormant for years. Endospores are non-reproductive structures resistant to radiations, starvation and chemical disinfectants.

If it is how you described it and there are not very many organelles on the inside, then I think it is a algae cell.
Answer choice B.
Negative feedback is when the system is always returning to the same consistant conditions.
A good example of negative feedback would be body temperature (always returns to normal, despite small flunctuations).
Positive feedback always progresses completely. Like growth (once you grow, you stay that way) & pregnancy (fetus is constantly growing and then undergoes childbirth, a forward process).
Hope that helps!
The term used to describe an organic cofactor is that this common chemistry allow cells to use a small set of metabolic intermediates to carry chemical groups between different reactions. These group-transfer intermediates are the loosenly-bound organic cofactors, often called coenzymes.
