Answer:

No change occurs in phenotype.

Explanation:

This can happen in many situations:

perhaps the mutation occurs in a stretch of DNA with no function, or perhaps the mutation occurs in a protein-coding region, but ends up not affecting the amino acid sequence of the protein.

A GeoChart is a tool used to visualize data on a map. The size of the circular

7nadin3 [17]

Explanation:

We know that the larger the circle, the more large the diameter of the circle the more the quantity being studied.

We can clearly see that the South eastern coast of Australia has more number of people diagnosed with cancer.

The South western and the Northern part also records a sizable amount of skin cancer cases.

In the middle part of the map where the circles are small, the number of people diagnosed with cancer is very low
Other areas without the circle did not record any case of skin cancer.

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.
