Biology
1 answer:
enot [183]3 years ago
5 0

Answer: Topoisomerases (or DNA topoisomerases) are enzymes that participate in the overwinding or underwinding of DNA. The winding problem of DNA arises due to the intertwined nature of its double-helical structure. During DNA replication and transcription, DNA becomes overwound ahead of a replication fork.

Which term best describes the change from more light-colored moths to more dark-colored moth:
maria [59]

Answer:

The correct option is B) adaptation

Explanation:

The features and properties of an organism that make it favourable to live in an environment are termed as the adaptations of that organism. Over time, evolution occurs and organisms with better adaptations survive as they are better suited to live in a particular environment. The light-coloured moths were adapted to live on Earth when the colour of the trees had not gone dark. With time, as the colour of trees got darker, the moth had to change colour to be better adapted to live on Earth.

Michelle drew a simple diagram to show how a hurricane forms. Which location on the diagram indicates a low-pressure area?
inysia [295]

Answer:

"Location 4" indicates a low-pressure area

Explanation:

A low-pressure area is defined as the region in which the pressure in the atmosphere is comparatively lesser than nearby surrounding areas. This region is a depression that is comprised of more winds, warmer air, and lifting of air mass takes place.

In a low-pressure zone, the warm air becomes less dense, due to higher temperature, as a result of which it rises up into the atmosphere. As it rises up into the atmosphere, it eventually cools and condensation starts taking place. After a definite period of time, rainfall occurs.

Thus, in the given image, location 4 shows the low pressure area.

german

Answer:

Fermentation is a chemical process that occurs in the cytoplasm since it is anaerobic, that is, with the absence of oxygen.

Explanation:

This anaerobic process is due to the consumption of carbohydrates in the absence of oxygen compared to intense muscular demands such as high-performance physical activity, that is why the obtaining of energy is high, since the purpose is not to anabolize but to catalyze hydrates in order to obtain the energy currency that is ATP and thus produce the contraction of the muscular sarcomero by the union of myosin with actin.
