<h2>Photosystems </h2>

Explanation:

Non cyclic electron flow starts with absorption of light (a photon) by photosystem II (PSII)

  • Upon absorption of photon by reaction center, P680 is excited to P680*
  • The excited P680* transfer one electron to pheophytin and converted in P680+
  • P680+ act as strong oxidizing agent and reduced by tyrosine, which receive electron from oxidation of water

Cyclic electron flow

  • It starts when ration of NADPH/NADP+ is high (means all NADP+ converted in NADPH)
  • Cyclic electron flow occurs when optimum sunlight and water is present
  • In cyclic electron flow quinone, cytochrome b6f complex, plastocyanin and photosystem I are involved

Long legs (L) in racing horses is dominant to short legs (l). Good muscle tone (G) is dominant to weak muscle tone (g). Determin
vova2212 [387]

Answer:

See the answer below

Explanation:

Long leg (L) is dominant over short leg (l) and Good muscles (G) is dominant over weak muscles (g).

Heterozygous long leg, weak muscle = Llgg

Heterozygous long leg, strong muscle = LlGg

       Llgg    x    LlGg

Offspring:

2 LLGg - Long leg, strong muscle

4 LlGg -  Long leg, strong muscle

2 LLgg - Long leg, weak muscle

4 Llgg - long leg, weak muscle

2 llGg - short leg, strong muscle

2 llgg - short leg, weak muscle

Ratio of offspring with long leg and strong muscle = 6/16 or 3/8

Ratio of offspring with long leg and weak muscle = 6/16 or 3/8

Ratio of offspring with short leg and strong muscle = 2/16 or 1/8

Ratio of offspring with short leg and weak muscle = 2/16 or 1/8
