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.
Answer:
9/16
Explanation:
Let broad, straight wings be represented by the allele W. Homozygous condition will be WW or ww while heterozygous condition will be Ww
Let pale-colored body with dark transverse stripes is represented by C. Homozygous condition will be CC or cc while heterozygous condition will be Cc.
Heterozygous condition for both trait will be WwCc. Hence a mating between two flies that are heterozygous for both trait will be;
WwCc x WwCc
This will yield offspring in the following phenotypic ratio;
Broad, straight wings with pale-colored body/dark transverse stripes - 9/16
Broad, straight wings with ebony body colour - 3/16
Nubby, vestigial wings with pale-colored body/dark transverse stripes - 3/16
Nubby, vestigial wings with ebony body colour - 1/16.
See the attached image for the Punnet square result of the cross.
The proportion is 9/16
Answer:
i think its the first one because i found this information that makes sence
Explanation:
Restriction enzymes are used in biotechnology to cut DNA into smaller strands in order to study fragment length differences among individuals. This is referred to as restriction fragment length polymorphism (RFLP). They're also used for gene cloning.
Idk I’m really sorry my friend
