What does KE= 6250J =
Kazeer [188]

The kinetic energy of 6250 J equals 6250 J work-done in stopping the object in motion.

The given parameters;

  • <em>Kinetic energy, K.E = 6250 J</em>

According to work-energy theorem, the work done in stopping a moving object is equal to the kinetic energy of the moving object.

Kinetic energy is the energy possessed by an object by virtue of its state of motion.

Work-done in stopping the object in motion = K.E = 6250 J.

Thus, we can conclude that the kinetic energy of 6250 J equals 6250 work-done in stopping the object in motion.

In fruit flies (Drosophila melanogaster) grey body is dominant to black body and normal wings are dominant to vestigial wings. I
zepelin [54]
The answer is C. We can suppose that the Grey gene is "A" and Black gene is "a". So the gene of heterozygous grey fruit fly is "Aa", and the black-bodied fruit fly is "aa". After mating, the offspring can get only "a" from balck-bodied fruit fly and has equal opportunity to get a "A" or "a" from heterozygous grey fruit fly. If the gene of offspring is "Aa", it will be grey. If "aa", it will be black. So the proportion of being black is 0.5.

Red blood cells (a good, colorful example of an animal cell type) when placed in pure water swell up and eventually explode. Why
Snowcat [4.5K]

Answer:

When red blood cells are placed inside pure water they normally swell up and eventually explode. Red blood cells in pure water swell up because the pure water enter in the red blood cells by mean of osmosis. The water molecules are able to enter the red blood cells because the salt concentration inside the red blood cells is more than that of the pure water.

As water continue to move inside the cells, the cell swell up and eventually burst because the internal pressure inside the cell is greater than the external pressure, therefore the cell membrane become ruptured and eventually burst.
