Answer: Deoxyribonucleic acid (DNA)
Ribonucleic acid (RNA
Explanation:
Nucleic acids are simply referred to as the macromolecules which aids in the storage of genetic information. It should also be noted that nucleic acids enable the production of protein.
Nucleic acids include the Deoxyribonucleic acid (DNA) and also the Ribonucleic acid (RNA).
Answer:
The widest part of the body is below the middle. The body of a paramecium is asymmetrical. It has a well-defined ventral or oral surface and has a convex aboral or dorsal body surface. Its whole body is covered with a flexible, thin and firm membrane called pellicles.
Explanation:
An experiment or survey must be controlled in order to receive accurate results.
In an experimental group, the independent variable is changed. But in the control group, the independent variable stays the same.
<span>The correct answers are that it lacks cells, DNA, and cannot maintain homeostasis. It doesn't have any organic matter and homeostasis is impossible because it would turn off eventually. It doens't have DNA and it doesn't reproduce. It's just plasma and it is not a living being, it just moves because of the chemical reactions that occur. </span>
Answer:
Iodine
Explanation:
Iodine is needed by animals because the body's metabolic rate is controlled by the action of an iodine hormone, called thyroxine, which is secreted by the thyroid gland in the neck.
If the animal fails to supply enough iodine through food to be able to make a normal amount of this compound, then the thyroid gland enlarges or expands trying to create enough, resulting in a common type of goiter.
