The three components of RNA are a phosphate group, ribose sugar, and a nitrogenous base
Vikki [24]

Answer:

The nitrogenous bases <u>Adenine (A), pairs with uracil (U), while guanine (G) and cytosine (C) pair up.</u>

Explanation:

Nucleotides are monomers that make up DNA and RNA- these are nucleic acids that function as storage, transport and messenger molecules for encoding proteins. Nucleotides contain a 5-carbon deoxyribose (with hydroxyl modifications) or ribose sugar (RNA), phosphate and one of four nitrogenous bases:

Adenine (A)

Guanine (G)

Cytosine (C)

Thymine (T).- DNA only

Uracil (U) found in RNA

Nucleotide monomers derive their names from their bases. Nucleic acid polymers form on a single strand through covalent bonding. This occurs between two nucleotides in an esterification reaction where a phosphodiester bond is formed.

Nitrogenous bases encourage hydrogen bonding, and resulting base pair formation.  Adenine (A), pairs with uracil (U), while guanine (G) and cytosine (C) pair up.

zhuklara [117]

Answer:

<em>It would cause a decrease in the carrying capacity of the owl population.</em>

Explanation:

The relationship between a predator and prey is unique. Both the population of a predator and prey gets affected if changes in one of them occur.

If mice migrated from the ecosystem, this will mean that there will b little food available for the owls on that ecosystem. As a result, they will compete for food. Some of them would get killed due to lack of food. Others will migrate to places where they can find food. Hence, the carrying capacity of the owl population would decrease.
