The sugar present in a molecule of RNA is ribose
The sugar present in a molecule of DNA is deoxyribose.

DNA uses A-T (Adenine-Thymine), G-C (Guanine-Cytosine)
RNA uses A-U (Adenine-Uracil), G-C (Guanine-Cytosine)

DNA functions as a medium of long-term storage and transmission of genetic information.
RNA transfers the genetic code needed for the creation of proteins from the nucleus to the ribosome. This process prevents the DNA from having to leave the nucleus, so it stays safe. Without RNA, proteins could never be made.

Choose all the answers that apply. Nitrogen dioxide: is a waste product of photosynthesis is formed when fuel is burned at high

GaryK [48]

The correct answers is:

is formed when fuel is burned at high temperatures

Nitrogen dioxide is another toxic gas that forms when fuels are burned at high temperatures.

is the most abundant gas in the atmosphere

The most abundant gas is nitrogen. Over 78 percent of the air we breathe is nitrogen (N)

can cause acid rain

Both nitrogen dioxide and sulfur dioxide can cause acid rain. The damage done by acid rain is devastating to the plants and animals in an ecosystem.

is a major pollutant in the air

AQI measures five major pollutants, including carbon monoxide, nitrogen dioxide (NO2), and sulfur dioxide (SO2).

Wrong answers:

is a waste product of photosynthesis

The waste product of photosynthesis is oxygen.

N the cross shown here, involving two linked genes, ebony (e) and claret (ca) in drosophila, where crossing over does not occur

jonny [76]

I found the full exercise on the internet and it ends like this:
"These genes are 30 cM apart on the third chromosome. Explain how this ratio arose." Attached is an image of the cross mentioned above.
Crossing over in the female contributed to the possible existing allele combination |e-ca| that did not exist in the parents genotypes. With this new allele combination, the new possibilities are |♀e-ca/♂e-ca+|, |♀e-ca/♂e+-ca|, |♀e+-ca+/♂e-ca+|, and |♀e+-ca+/♂e+-ca|, leading to the respectively phenotypes ebony, claret, wild, wild. These results correspond to the obtained phenotype ratio.

In general, how do most nutrients reach the mesopelagic and bathypelagic zones? 1, Nutrients sink into these zones from the epip

Bumek [7]

The answer is; 1

Most of the photosynthetic organisms are located in the epipelagic zone of the oceans where sunlight can penetrate before diffusing and becoming too weak to support photosynthesis. The epipelagic zone is filled with plankton. When this plantkon die, they begin to sink slowly to the bottom of the ocean. These plankton are food for small fish. These small fish are food for bigger fishes. This is how an ecosystem is sustained in the deep dark oceans.
