Answer:
B)Genome
Explanation:
Archaea (Archaea) are single-celled microorganisms. Like bacteria, archaea lack a nucleus and are therefore prokaryotic. However, the differences at the molecular level between archaea and bacteria are so fundamental that they are classified into different groups. In fact, these differences are greater than there are, for example, between a plant and an animal. <u>Currently, archaea are considered to be </u><u>phylogenetically</u><u> closer to eukaryotes than to bacteria.</u>
Eubacteria are also known as "true bacteria", they are microscopic organisms that have prokaryotic cells. Because of their prokaryotic cells, they have a rigid cell wall, but they don't have mitochondria or other large organelles; They only have one chromosome, which is not found in the nucleus. Most of them reproduce asexually
Radioactive elements comprise a majority of the "ACTINIDES"
These are elements in the bottom row of the periodic table.
Food is a basic need for all organisms
If denaturation occurs (extreme temperature change or pH changes), the enzyme will not be reusable! The structure of the enzymes are not changed. As a result of this, enzymes will be used again and again to bind onto another substrate molecule and catalyze the reaction once again.
