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.

Round seeds and yellow seed color are dominant to wrinkled seeds and green seed color. What is the probability of having offspri
adoni [48]

Answer:

<h2>The probability of a cross between RRYY x RrYy to generate a yellow and wrinkled seed offspring is 0%.</h2>

Explanation:

Circular and yellow seeds are overwhelming and wrinkled and green seeds are passive. It is vital to keep in mind that resective characteristics are as it were displayed when the sibling has two passive alleles for those characteristic, in the event that the descendant includes a latent allele and a overwhelming allele, the characteristic that will be presented is the overwhelming one. For this reason, able to say that a cross between RRYY x RrYy plants, would not create any descendant with wrinkled and yellow seeds. Typically since, the descendant of a crossing, must show an allele of each parent. One parent as it were has overwhelming alleles (RRYY), so able to say that all descendant will get 1 overwhelming allele for color and a overwhelming allele for seed surface, anticipating the sibling from communicating latent characteristics.
