We breath oxygen because it is needed to burn fuel [ sugars and fatty acids] in our cells to produce energy. Oxygen is also brought into the lungs via breathing; where it is transported by red blood cells to the entire body to be used to produce energy. The food we eat gives us protein, sugars, vitamins etc. for energy

2. A male rabbit with the genotype GGbb is crossed with a female rabbit with the genotype ggBb
bekas [8.4K]

Answer:

- Half (8/16) of the offspring will have gray fur and black eyes.

- Half (8/16) of the offspring will have gray fur and red eyes.

- None (0/16) of the offspring will have white fur.

Explanation:

For the purposes of this question, we will assume the following notation for the involved alleles:

G: gray fur (dominant), g: white fur (recessive).

B: black eyes (dominant), b: red eyes (recessive).

A GGbb rabbit may only produce one type of gametes, namely Gb.

A ggBb rabbit may produce either gB or gb gametes.

Since not all theoretical combinations are present, the resulting Punnett square may be simplified as follows:

       |     Gb

——-+-————

gB   |   GgBb

——-+-————

gb   |   Ggbb

As seen above, 100% of the offspring will have a Gg genotype (resulting in gray fur). As for eye color, half of them will have a Bb genotype (resulting in black eyes) whereas the other half will have a bb genotype (red eyes).

Which technique involves injecting an animal with a radioactive molecule to see which part of the olfactory bulb is most activat
Rudiy27

The asnswer is 2DG also known as 2-Deoxy-D-glucose.  2DG is a glucose molecule that has the 2-hydroxyl group replaced by hydrogen, so that it cannot undergo further glycolysis. As such; it acts to competitively inhibit the production of glucose-6-phosphate from glucose at the phosphoglucoisomerase level (step 2 of glycolysis).
