Which option describes a condition required for natural selection to occur?
Vika [28.1K]

Answer:

You need to know the conditions required for natural selection to occur. These include: overproduction of offspring, inherited variation, and the struggle to survive, which result in differential reproductive success. You need to understand genetic drift and gene flow

1. What type of response will a red blood cell have when placed in a hypertonic solution?
GalinKa [24]
Hypertonic solution means the solution with a lower water potential than the cell cytoplasm, such as salt water.

When the red blood cell is put into it, since the cell has a higher water potential than the solution, water molecules will flow from the cell back into the water due to osmosis.

Osmosis is always where water molecules flow from a region of higher water potential to lower, through a semi permeable membrane (Whcih is the red blood cell membrane in this case.)

Since water flowed out of the cell, the cell lose water and shrinks.

Hypotonic solution is where the solution that has a higher water potential than the cell cytoplasm.

So when the red blood cell is put in that solution, the water will flow from the solution into the cell this time, by osmosis.

The red blood cell will then gain so much water that the cell membrane cannot hold all and therefore burst.

4. Which pathway represents the flow of electrons during photosynthesis? (1 point) A.) H2O > Photosystem I > Photosystem I
Yuki888 [10]

Answer:

4. The correct pathway for the flow of electron during photosynthesis is mentioned in option D. H_{2}O > <em>NADP </em>> <em>Calvin cycle.</em>

  • Electron is first provided to the photo-system II by the phtolysis of water.
  • Then it is passed to photo-system I with the help of plastoquinone (PQ) and cytochrome b_{6}f.
  • Finally, electron from the photo-system II is used to reduce NADP to NADPH.
  • NADPH and ATP are used in light independent phase or Calvin cycle to synthesize carbohydrate from carbon dioxide.

5. The correct answer is B.) photosynthesis.

  • Photosynthesis is the process by which green plants synthesize glucose or carbohydrate from carbon dioxide and water in presence of sunlight and chlorophyll.
  • In light independent phase of photosynthesis, it requires ATP and NADPH  in order to synthesize food.
  • Lastly, oxidation or breaking down of glucose releases energy and photosynthesis is a anabolic process instead of catabolic one.

(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.
