Answer: Option B) phosphate; hydroxyl; 3'

We identify nucleic acid strand orientation on the basis of important chemical functional groups. These are the phosphate group attached to the 5' carbon atom of the sugar portion of a nucleotide and the hydroxyl group attached to the 3'

carbon atom

Explanation:

For both RNA and DNA, chemical groups such as phosphate (PO3-) attaches to the 5' carbon of the pentose sugar (deoxyribose in DNA, ribose in RNA).

While hydroxyl group (OH) attaches to the 3' carbon atom of the pentose sugar.

Thus, a nucleic acid structure structure reveals a several repeating units of nucleotides where nitrogenous base links to a pentose sugar, who in turns is linked to phosphate group

<span>For instance, during the concentration of salt in water affects the rate of osmosis because it will determine how much water should be transported or excreted or to be taken in. The cellular process is keen to the salt concentration of its system thus making sure to maintain balance between the salt concentration the right amount of water must also be in its area of release for any expected occurences. </span>

. Daughter cells produced when cells undergo mitosis are genetically _______, and daughter cells produced when cells undergo mei
Radda [10]
Answer; 
D. identical, diverse
Daughter cells produced when cells undergo mitosis are genetically identical, and daughter cells produced when cells undergo meiosis are genetically diverse.

Explanation; 
Meiosis and mitosis are the two major types of cell division. Mitosis takes place in the somatic cells (body cells) in which parent cells undergo division to yield daughter cells that have similar number of chromosomes as the parents. Meaning the daughter cells are identical to the parent cells in terms of genetic material composition.
Meiosis on the other hand, involves division in the germ-line cells in which parent cells divides to yield daughter cells that contain half the number of chromosomes as the parent, meaning that they are not genetically identical, however they re genetically diverse due to the process of crossover and recombination.

During gas exchange, the cell membrane of a single-celled organism has the same function as which organ system in humans?
victus00 [196]

During gas exchange, the cell membrane of a single-celled organism has the same function as the respiratory system in humans. The respiratory system is a biological system which is composed of specific organs and structures such as nose, pharynx, larynx, trachea, bronchi and lungs that are used for gas exchange in humans. The primary function of the respiratory system is to transport oxygen into the body and to breathe out carbon dioxide, which is a waste product of cellular function
