Answer:

Explanation:

Promoter region on DNA is the point on DNA where polymerase enzyme attaches so it can begin the translation of genes/operon downstream. Terminator region on the DNA is the point that causes the polymerase to terminate transcription. For example, the terminator regions may cause the transcribed nascent mRNA to form a hairpin structure at the terminator sequence hence causing the polymerase enzyme to detaches from the DNA strand.

The flow of air caused by ____ and the Coriolis effect creates distinct wind patterns on Earth's surface. a. differences in heat

kakasveta [241]

<h3>Answer;</h3>

Differences in heating

The flow of air caused by differences in heating and the Coriolis effect creates distinct wind patterns on Earth's surface.

<h3>Explanation;</h3>

Movement of air or flow of air is caused by pressure or temperature differences and is experienced as wind. When there is a pressure difference between two places, a pressure gradient exists, across which air moves from the region of high pressure to the region of low pressure.
Differences in temperature also causes movement of air or wind know as convection. The air flow caused by temperature difference is observed in the case of sea and land breezes, because of the difference in temperature between the sea and the land.

garri49 [273]

Answer:

Hey mate......

Explanation:

This is ur answer.....

1A) There are 2 ways:-

• Anaerobic Respiration.

The anaerobic respiration process takes place in the absence of oxygen. 

• Aerobic Respiration. 

In aerobic respiration, breakdown of pyruvate takes place in the presence of oxygen to give rise to 3 molecules of carbon dioxide and water.

2A) Oxygen is transported from lungs to body cells in the form of oxyhemoglobin . the main 2 gases exchanged are 02 & C02 . 02 is absorbed by blood capillaries from lungs alveoli by diffusion while C02 is absorbed by blood alveoli from blood capillaries by diffusion.
