We identify nucleic acid strand orientation on the basis of important chemical functional groups. These are the _________ group
Alina [70]

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

How do some plants survive the intense desert heat and drought?
viva [34]

The correct answer is:

Plants close their stomata during times of intense heat or drought in order to prevent water loss and maintain homeostasis.

Explanation:

Guard cells tend to open stomata within the day when there are lots of day and close stomata at night when the sun is not present and photosynthesis is not happening. They will also close stomata if the air is dry or hot, which minimizes water waste indoors evaporation.
