why is DNA referred to as the genetic code?

Answers

The genetic code is the set of rules by which information encoded in genetic material (DNA or RNA sequences) is translated into proteins (amino acid sequences) by living cells. Those genes that code for proteins are composed of tri-nucleotide units called codons, each coding for a single amino acid.

Explain how the sun's heat drives the circulation of water between the land, oceans, and atmosphere.

Answers

Answer:

The water cycle.

Explanation:

The sun drives the movement of water through a process called the water cycle. In this process, water is evaporated from the sun's heat that reaches Earth. This water rises into the atmosphere in the for of water vapor. This water vapor then collects in the atmosphere along with other particles such as fine dust. This water then precipitates back onto the Earth. Presumably, the water precipitation may fall onto a land formation and integrate back into the ecosystem in the form of ground water or join a steam/river and end up in a lake or the ocean. The water then continues this cycle.

4a. By 40-60 years after farm fields had been abandoned, the amount of herbaceous plants

decreased. Give one reason why the amount of herbaceous plants decreased as the amount of trees

increased.

Answers

Answer:

See the answer below

Explanation:

The amount of herbaceous plants in an abandoned farm field will keep decreasing with time and the amount of trees would be increasing instead due to successional forces.

Succession refers to the gradual change in the species structure of a community with time. Early successional species usually colonize new habitats and with time, they are replaced with late successional species until a relatively stable community, climax community, is established.

Herbaceous species on abandoned farmland represent early successional species and as time goes on, they will be replaced by mid to late successional species in the form of shrubs and trees until a relatively stable community is formed. Hence, herbs would be decreasing while trees would be increasing.

d) storage of energy, insulation, waterproof coverings, cell membranes and hormones

Answers


It’s between b and d. I would go with b based on the information below.

The four primary functions of carbohydrates in the body are to provide energy, store energy, build macromolecules, and spare protein and fat for other uses. Simple carbohydrates are quick energy sources, but they do not usually supply any other nutrients or fiber. One of the most important functions of carbohydrates is to form a structure called the glycocalyx. This is a coat around the cell.
