Answer: If the F2 occurs in the ratio 9 blue:3 pink:4 white, one gene pair (i.e 2 genes) control the flower color phenotype.
Explanation: This principle is called INCOMPLETE DOMINANCE where one gene (dominant) won't completely override the other (recessive).
Let assume B represents the dominant gene and b represents the reccesive gene. Let also assume that Blue color is dominant over white color. We can assign the genotype as follows;
Homozygous dominant genes BB will produce Blue color
Homozygous recessive genes bb will produce white color
Heterozygous genes Bb will produce pink color.
Therefore, a pair of gene ( 2 genes) will determine the flower color phenotype.
Answer:
Photosystem I, however, does not act as a proton pump; instead, it uses these high-energy electrons to reduce NADP+ to NADPH. The reaction center chlorophyll of photosystem I transfers its excited electrons through a series of carriers to ferrodoxin, a small protein on the stromal side of the thylakoid membrane.
Explanation:
Explanation:
Well, its extremely hot in the hydrothermal vents. Scientists simply believed it would be impossible for anything to survive due to the heat. Bacteria and micro-organisms were able to adapt to growing there, though. So in short words, they survived extreme conditions teaching scientists that life was quite adaptable.
Weird fun fact: In Switzerland it is illegal to own just one guinea pig. Felt the need to mention that ^ Sorry, I know it has nothing to do with the question but i felt it was worth speaking of.
Answer:
cell membrane
Explanation:
The cell membrane in the diagram consists of lipids, bilayers, and proteins. The lipids, located within the cell membrane, are known as hydrophobic, meaning they are afraid of water. In other words, the lipids keep out the water. Whereas the bilayer, otherwise known as the phospholipid bilayer, is attracted to water. While the proteins simply enable molecules and other microscopic parts travel within and out the cell membrane, through the protein.
Lithosphere would go with Solid Rock.
Outer Core would go with Liquid Iron.
Inner Core would go with Solid Iron.
Asthenosphere would go with Liquid Rock.
Hope I helped!
