Only one type of cell was given, but different types of cells are structured differently in response to what function they need to perform.
For example, muscle cells are like that because they need to be flexible. Bone cells, however, are compact. This is because bone cells need to be durable, to keep the body together.
The correct answer is urea.
Urea is formed from the deamination (removal of amine group) of amino acids producing a highly toxic ammonia. Ammonia will then join carbamyl phosphate to form citrulline. Citrulline will then cycle through the urea cycle until it forms arginine. Arginine then will be broken down to ornithine and urea. Urea is excreted in the urine and ornithine is used to replenish citrulline.
The answer is Eubacteria
Their spores can become temporarily inactive if the environment is harmful to them. They will become active again when the enviroment is suitable for their living
