d1i1m1o1n [39]2 years ago
3 0

Answer:  change the shape of the active site of an enzyme

Explanation:

Enzymes are also sensitive to pH . Changing the pH of its surroundings will also change the shape of the active site of an enzyme. ... This contributes to the folding of the enzyme molecule, its shape, and the shape of the active site. Changing the pH will affect the charges on the amino acid molecules.

A true-breeding plant that produces yellow seeds is crossed with a true-breeding plant that produces green seeds. The F1 plants
nadya68 [22]

Answer:

The phenotypic ratio will be 3:1

Explanation:

As per this question there are two phenotypes for seed color, yellow and green. Both the parents are true breeding that means they are homozygous for this trait. Also, all the F1 plants have yellow seed color which clearly indicates that yellow seed color is a dominant trait while green is recessive trait.

The cross of true breeding plants as mentioned above is depicted as under:

Parents                             YY    x   yy

                                          /   \       /   \

F1 generation                Yy   Yy  Yy   Yy

So, as per the law of dominance because of the presence of Y allele, all these progeny will be yellow in color.

Next, when these F1 plants will be crossed, the result will be as under:

F1 generation                    Yy   x    Yy

                                         /   \         /   \

F2 generation               YY   Yy   Yy   yy

The genotypic ratio of F2 generation is 1:2:1

The phenotypic ratio of F2 generation is 3:1

It simply means that in F2 generation, 3 progeny which have allelic combination YY & Yy will be yellow colored while 1 progeny which has allelic combination yy will have green color.

I’m stage 2 of photosynthesis NADP becomes NADPH why?
nignag [31]
NADPH is a reduced form of NADP+. The latter features an extra hydrogen ion in its chemical structure. When NADP+ transforms into NADPH, the other hydrogen ion  is released as part of the reaction while the other hydrogen ion becomes a part of the NADPH structure.

Which graph most likely represents a rabbit population that found a new, larger habitat, but then eventually experienced an
klio [65]

The graph will have a sharp curve in upwards manner when the new, larger habitat is found, but than will be followed by slight decrease when the predation increases.

Explanation:

If a population of rabbits finds a new, larger habitat, than the population will experience rapid rise, especially if there isn't high scale predation on them. This will be due to the abundant food resources, but also because of the fast reproduction of the rabbits. The low predation will mean that most of the rabbits will survive, so the numbers will be on the rise.

When the population starts to experience in increase in predation, the situation changes. The larger number of predators means that they would need much more food, so much more rabbits will be killed and consumed by the predators. This will stop the population rise, and it will either stagnate, or most probably it will experience slight decline.
