There are two types of self-pollination: in autogamy, pollen is transferred to the stigma of the same flower; in geitonogamy, pollen is transferred from the anther of one flower to the stigma of another flower on the same flowering plant, or from microsporangium to ovule within a single (monoecious) gymnosperm

Answer:

1/65,536 = 0.001523 %

Explanation:

A: normal allele

a: recessive allele causing PKU

The probability that Rosie and Ross have one child with PKU will be >>  

Aa x Aa = 1/4 AA; 1/2 Aa; 1/4 aa

The Calvin cycle is considered light-independent because it can occur in darkness. However, most often the Calvin cycle takes pl
GarryVolchara [31]

Answer:

C) The Calvin cycle requires ATP and NADPH, which require sunlight to be produced

Explanation:

The light-dependent phase of photosynthesis includes the photolysis of water molecules. The released electrons are passed to PSII to PSI via electron carriers and finally to NADP+ to reduce it into NADPH.

Transfer of electrons via electron carriers also generates the proton concentration gradient which in turn drives ATP synthesis. ATP and NADPH formed during light reactions are used in the Calvin cycle as an energy source and electron donor respectively.

Hence, to continue, the Calvin cycle requires the synthesis of ATP and NADPH in the presence of light.
