Which of the following statements about Ngb-H64Q is true?
Free_Kalibri [48]

Answer:

b. Ngb-H64Q has a higher affinity than hemoglobin for both carbon monoxide and oxygen. However, Ngb-H64Q binds to carbon monoxide with a higher affinity than to oxygen.

Explanation:

A study of neuroglobin (Ngb),  a hemoglobin-like protein present in the brain, was done at the University of Pittsburgh by a team of researchers. Upon testing the red blood cells of a mouse that contained carbon monoxide, they found that Ngb-H64Q was significantly better at removing CO from hemoglobin than 100-percent oxygen treatment. Hence Ngb-H64Q binds to carbon monoxide with a higher affinity than to oxygen.

13. Which hormone does the thymus secrete?
zvonat [6]

Answer: G. thymosin and thymopoietin

Explanation:

The thymus produces and secretes thymosin, a hormone necessary for T cell development and production. The thymus is special in that, unlike most organs, it is at its largest in children. Once you reach puberty, the thymus starts to slowly shrink and become replaced by fat.

If you could monitor the activity from the photoreceptors of rods and cones in the retina during a dream, would you expect these
loris [4]

The question is incomplete as it does not have the options which are:

- Yes, because people's eyes move during sleep, and this stimulates the rods and cones.

- No, because rods and cones only convert light energy into electrical signals.

- No, because rods and cones never produce electrical signals.

- Yes, because the rods and cones are reproducing images that are then sent to the brain.

Answer:

No, because rods and cones only convert light energy into electrical signals.

Explanation:

The rod and cone cells are the photoreceptor cells present on the retina of the eye which receives the physical stimulus in the form of light and then converts the light energy into the electrical energy which is sent to the brain.

When we dream, our remains closed and no light is able to enter the eye as a result of which the rods and cones do not send the signals to the brain.

Thus, the selected options are correct.

In 1998, scientists discovered that the expansion of the universe has been accelerating.
KengaRu [80]

Answer:

Option A (dark energy) is the right answer.

Explanation:

  • A hypothetical supplier of power that creates a force that contradicts gravity, which is assumed to have been the catalyst of accelerated universe development.
  • Hypothetically, dark energy counteracts the kinetic energy including its beginning of the globe, meaning that perhaps the multiverse does not have intrinsic curvature, although observational measurements presently indicate.

Some other three choices have no relation to the particular situation. Thus option A would be the right solution.
