The right answer for the question that is being asked and shown above is that: "B. Proportional to the amount of food taken in by the cell" If energy is needed to remove a phosphate group from a chain in ATP, you can conclude that the energy needed for production must be p<span>roportional to the amount of food taken in by the cell</span>

Phosphofructokinase is an allosteric enzyme that catalyzes the conversion of fructose 6-phosphate to fructose 1,6-bisphosphate,
zhenek [66]
I believe in the presence of oxygen, an increase in the amount of ATP in a cell would be expected to inhibit the enzyme and therefore, slow the rates of glycolysis and the citric acid cycle. Phosphofructokinase is and enzyme that phosphorylates fructose 6 phosphate in glycolysis. It is an important control enzyme in the regulation of cellular respiration. It is inhibited by ATP and is an allosteric enzyme.

at which location does gravity play a role in moving tectonic plates? at the edge of the plates. in the core. in the mantle. in
yulyashka [42]

Answer:

B. At the edge of the plates

Explanation:

<u>Gravity </u>is the principal <u>driving force </u>of <u>plate tectonics </u>(second one is convection<u>)</u>. It causes different density plates to move on the Earth's surface. However, when a <u>denser plate coincides the less denser plate, the high density plate subducts</u> below the <u>lesser density plate</u>. The process, therefore, is called <u>subduction</u>. During this collision of plates, <u>shearing resistance increases</u> and all <u>pressures come at the edge of the plate</u>. The process continues and the lithosphere drags the rest of the plate. The portion of plate below the less denser plate then reaches the mantle. Here, the edge of plate is destroyed due to high temperature of mantle as well as pressure.

To measure the population of lake trout in a 250-hectare lake, 400 individual trout were netted and marked with a fin clip, then
kenny6666 [7]

Answer:

Estimated size is 1600

Explanation:

Given data:

Size of lake is 250 hectares

Total number of trout who netted is 400

Total number of trout in next week is 200

Total number of trout having fin clip 50

estimation population size is estimated by mark rupture as follow

Estimated population size = \frac{(marked\ initally \times total\ recaptured)}{mark\ recaptured}

Estimated size= \frac{400\times 200)}{50}

Estimated size is 1600

n Drosophila melanogaster, forked bristles are caused by an allele (Xf) that is X linked and recessive to an allele for normal b
makkiz [27]

Answer:

Proportion of the F2 male with red eyes and forked bristle will be 1/4

Explanation:

forked bristles are caused by an allele (Xf) that is X linked and recessive to an allele for normal bristles (X+).

Brown eyes are caused by an allele (b) that is autosomal and recessive to an allele for red eyes (b+)

A female fly that is homozygous for normal bristles and red eyes mates with a male fly that has forked bristles and brown eyes

    X+X+b+b+  x    Xfbb

the F1 gives   1/2X+Xf 1/2b+b

                      1/2X+Y  1/2b+b

intercross of F1

      Proportion of the F2 male with red eyes and forked bristle will be

      forked bristle= Xfy = 1/2 and for red eyes  2/4= 1/2  = 1/2x1/2 =1/4

The barley plant has seven pairs of chromosomes. For a gamete, the number of genetic combinations that are possible through inde
umka2103 [35]

1) The correct answer is: 128 combinations.

The genetic combinations that are possible through independent assortment can be calculated as 2^n; where n is the number of different chromosomes.  

So, using this formula for 7 chromosomes:

   2^7 = 128 different combinations.

2) For a zygote produced by two barley parents, the number of possible genetic combinations can be calculated as: 2^n * 2^n

So, for 7 chromosomes: 2^7 * 2^7=16384
