4 0

Answer:

Amylose in starch is responsible for the formation of a deep blue color in the presence of iodine. The iodine molecule slips inside of the amylose coil. ... A blue-black color results if starch is present. If starch amylose is not present, then the color will stay orange or yellow. I hope this helps!

what are the disc shaped membranous structures inside of the chloroplast where the light-dependent reactions take place
timofeeve [1]

Answer:

These are the thylakoids

Explanation:

The thylakoids which contains the chlorophyll is  the primary site of photosynthesis. It  is covered by layers of cell called the thylakoid membrane.These are the actual site for light dependent reaction.This membrane contains both photosytem I and ii, ATPase enzymes, and Cytochrome b6f complex.While the photosystem i and ii transfer elecrons during photosynthesis, the ATPase enzyme control the catalysis the phosphorylation of ADP to ATP needed for the light independent stage, the Cytochrome  proteins  acts as the ETC. involved in the transfer of electron during light dependent stage.

When thylakoids are packed together in disc shape they are refer to as Grana,(singular -granum).Each  grana are linked together by intergrana.Thus two or more grana are linked by intragrana to form a single photosynthetic functioning unit.The entire structure is bath continuously by the fluid medium-Stroma.

Their stacked and  disc shape is to increase the surface area available to accommodate enough  ETC, needed to transport electron for chemiosmosis needed for photosynthesis.

If a man with type AB blood and a woman with type O blood were to have children, what is the probability that a child would have
sineoko [7]

Answer:

0%

Explanation:

Let's use a Punnett square to solve this problem.

      A    B

O  AO  BO

O  AO  BO

The Punnett square shows that 50% of their children will have the AO genotype and 50% will have the BO genotype. Neither of these genotypes give the child type O blood, so it is impossible for the child to have type O blood. The child would need two O alleles.
