It differs due to the life cycle of each tree, and the very specific way the trees go.

In the light dependent reactions light energy is absorbed by the photosytem II and an electron is released. This electron causes a process called photolysis to occur(H20-->2H++2e-+1/2O2). This is how O2 is released in the atmosphere. The electrons resulted from photolyisis enter the electron transport chain. In the electron transport chain using the energy in the elecrtons, hydrogen protons are pumped inside the thylakoid. Those protons accumulate to form an electrochemical gradient. That means the protons need to flow out, and they do through an enzyme called ATP-synthase which turns ADP and inorganic phosphate into ATP and water. In the electron transport chain, the electrons reach Photosystem I where NADP+ is reduced and becomes NADPH.

ATP and NADPH store the energy absorbed in the light dependent reactions. Those two molecules are needed when CO2 is fixated in Calvin's cycle to synthesize glucose.

What is a membrane potential and how is it generated?

34kurt

Answer:

Differences in the concentrations of ions on opposite sides of a cellular membrane lead to a voltage called the membrane potential. Typical values of membrane potential are in the range –40 mV to –70 mV. ... These concentration gradients provide the potential energy to drive the formation of the membrane potential.

In the fruit fly Drosophila, there is a dominant gene for normal wings and its recessive allele for vestigial wings. At another

aev [14]

Answer:

Explanation:

The genes for vestigial wings (vg) and purple eyes (pr) are linked on the same chromosome.

The following cross was made:

Heterozygous male for both genes X female vg pr / vg pr

The male could be either vg+pr+/vg pr or vg+ pr/vg pr+.

The female only produces vg pr gametes.

The following offspring was observed:

420 Normal wings and red eyes (vg+ pr+/vg pr)

430 Vestigial wings and purple eyes (vg pr / vg pr)

80 Vestigial wings and red eyes (vg pr+ / vg pr)

70 Normal wings and purple eyes (vg+ pr / vg pr)

Total: 1000

The individuals observed in the highest frequency have the parental genotypes. The recombinant individuals are vg pr+ / vg pr and vg+ pr / vg pr.

Distance = Number of recombinants × 100 / Total

Distance = (80 + 70)×100 / 1000

Distance = 15 cM.

Just a small note, male drosophila do not experience crossing over in meiosis, so there would be no recombinants observed from this cross. The problem is probably mixed up, the female should be heterozygous and the male the homozygous recessive.
