Low temperature is the most responsible factor for lack of plants in polar regions.

<u>Explanation:</u>

Due to extreme low temperatures in the polar areas, the soil in this area is completely frozen. In this case, the roots of the plants do not grow very deep. Therefore, there is little or no thick vegetation in this region.

The polar climate is a place where the available temperature is usually lower than cold, icy, snowy and does not get direct sunlight.  The Polar Regions, also known as frigid areas. These are planet regions that cover the geographical poles (north - Arctic and south - Antarctic) and are located in the polar Circle.

7) Other than sunlight for energy, photosynthesis in plants needs these two things that we breathe
almond37 [142]

Answer:

Oxygen is needed to break the sugar into carbon dioxide, releasing energy the plants can use to stay alive. However, plants also take in energy from the sun(light), carbon dioxide from the atmosphere, and water from the soil; they use all of them in order to make sugar, and release oxygen.

Describe the relationship between organic compounds, nucleotides, RNA, and a universal genetic code.
makkiz [27]

Answer:

Organic compounds→ nucleotides→ RNA→ universal code.

Organic compounds are the compounds made by living organisms with at least one molecule of carbon linked to different elements like hydrogen, oxygen, or nitrogen.for example: nucleotides.

A nucleotide is the monomer units of nucleic acids- DNA and RNA. Each nucleotide is made up of organic compounds- sugar, a phosphate molecule and nitrogenous bases (adenine, guanine, cytosine, thymine and uracil).  

The arrangement of nitrogenous bases in DNA decides the fate of proteins as the sequence of these bases acts as code arranged in the triplet called "codons" which code for specific amino acids.

Thus, Organic compounds→ nucleotides→ RNA→ universal code is the correct answer.

What are nucleic acids made of?
LekaFEV [45]

Answer:

Explanation:

nucleic acid is a polymeric macromolecule made up of repeated units of monomeric 'nucleotides' composed of a nitrogenous heterocyclic base which is either a purine or a pyrimidine, a pentose (five carbon) sugar (either ribose or 2′-deoxyribose), and one to three phosphate groups.
