In 1978 scientists figured out how to implant traces of human DNA into E. Coli bacteria. This allowed the scientists to breed ba

cteria that produced human insulin. Insulin is a chemical that humans produce to help regulate blood sugar. Without insulin, people would die. Some people can’t produce the proper amount of insulin on their own, so being able to manufacture it in a lab using bacteria literally saves millions of lives a year.
Can you think of another problem that selective breeding could solve? How could you use selective breeding to solve that problem? What would you need to do?

Anastasy [175]

Answer:

The correct answer is "cell lysis due to the effect of osmotic pressure".

Explanation:

The cell wall is a structure that brings protection from the outside world and also helps to maintain the cell's water balance. The cell wall prevents that the cells is exposed to a large amount of turgor pressure, making the cell turgid when it is under extremal conditions. Some antimicrobials, such as bacitracin, block cell wall synthesis which makes the cell unable to support turgor pressure, resulting in cell lysis due to the effect of osmotic pressure.

(1)

Troposphere – This is the densest layer and where weather events occur

Stratosphere – This is where the ozone layer is found. Some high altitude aircraft cruise in this layer.

Mesosphere – Temperatures drop with altitude in this layer

Thermosphere – This is where most of the meteorites that enter the earth’s atmosphere burn up. This layer takes up most of the Uv and X-rays from the sun. Most satellites orbiting earth are in this layer

Exosphere – almost akin to space due to the thinness of the layer. Molecules in the layer often escape into space

(2)

A ‘pause’ is a transition between the above-mentioned distinct layers. The tropopause, for example, occurs between the troposphere and the stratosphere and the stratopause between the stratosphere and mesosphere and thermopause is found between thermosphere and exosphere.

(3)

A temperature inversion is a rise in temperatures with altitude in a layer in the atmosphere. One layer exhibiting temperature inversion is the stratosphere. This is due to the ozone layer that absorbs UV light. The upper ozone absorbs most of the UV light, than lower ozone, exciting the molecules and making the higher altitudes in the layer to be warmer.

(4)

The ozone layer protects life on earth from the high energy UV radiation from the sun. UV is capable of causing double-stranded break on DNA resulting in genetic mutations on organisms. Most of these would be lethal. The Ozone absorbs most of the UV before it reaches earth's surface. Ozone is formed when an oxygen molecule reacts with another oxygen atom to form an O₃. The oxygen atoms are made from the splitting of an oxygen molecule by UV light.

Which is the correct description of flow of blood to the proper structures?
MAVERICK [17]
<span>Answer: Blood leaves the left ventricle through the aorta.

The blood that is pumped from the heart and goes through all of the body structures, that need to be irrigated, leaves from the left ventricle. This ventricle will contract and push the blood to go to the aorta. From there, goes to the rest of the body.
