Both light-dependent and light-independed reactions of photosynthesis are similar in a way because they both require chemical energy to proceed.

Photosynthesis occurs in two successive stages. These stages are:
1) The light-dependent reactions
2) The light-independent reactions

The light dependent reactions absorb energy from sunlight and converts it into chemical energy. The chemical energy produced (ATP) by the light-dependent reactions is used by the light-independent reactions for it to function properly. The remaining chemical energy (ADP) in the light-independent reactions is returned to the light-dependent reactions to obtain more energized electrons.

Two genes determining a trait In primroses, the dominant allele of gene K is necessary to synthesize blue flower pigment. Blue p
viktelen [127]

Answer:

The ratio of blue to white offspring in the progeny is 4 blue : 12 white.

Explanation:

<u>Available data:</u>

  • The dominant allele K is necessary to synthesize blue flower pigment
  • K is inhibited by the dominant allele D
  • Plants with the genotype K- D- will not produce pigment (and their flowers will be white)

Cross: testcross for (Kk Dd) plants

Parental)   KkDd     x     kkdd

Gametes) KD   kD   Kd   kd      

                kd   kd   kd   kd

Punnet square)        KD        Kd       kD       kd

                      kd     KkDd   Kkdd   kkDd   kkdd

                      kd     KkDd  Kkdd   kkDd   kkdd

                      kd     KkDd   Kkdd   kkDd   kkdd

                      kd     KkDd   Kkdd   kkDd   kkdd

  • Whenever D is present, it inhibits the expression of the K gene, so every plant with the dominant D allele will be white. This plants´ genotype is kkD- or K-D-.
  • Whenever D is absent and K is present, every plant with genotype K-dd will be blue.
  • The recessive form for K and D genes will express white-flowered plants, with genotype ddkk

F1) Progeny genotype: 4/16 KkDd, white-flowered plants

                                      4/16 Kkdd, blue-flowered plants

                                      4/16 kkDd, white-flowered plants

                                      4/16 kkdd, white-flowered plants

     The ratio of blue to white offspring in the progeny is 4 blue : 12 white.

     Blue-flowered plants: 4 Kkdd

     White-flowered plants: 4 KkDd + 4 kkDd + 4 kkdd

What replaces the electrons excited by sunlight in photosystem?
d1i1m1o1n [39]

Answer:

To replace the electron in the reaction center, a molecule of water is split. This splitting releases an electron and results in the formation of oxygen (O2) and hydrogen ions (H+) in the thylakoid space.

What is mechanical digestion? Describe the first stage of mechanical digestion.
Mrrafil [7]

Answer:

Mechanical Digestion

The large pieces of food that are ingested have to be broken into smaller particles that can be acted upon by various enzymes. This is mechanical digestion, which begins in the mouth with chewing or mastication and continues with churning and mixing actions in the stomach.
