Since the radiation has no mass .It is Gamma radiation.

Step by Step Explanation:

Characteristics of Gamma radiation are as follows:

  • Gamma radiations are chargeless.
  • It is Electromagnetic wave having a very short wavelength.
  • It is not effected by the electric or magnetic field.
  • It has velocity equal to light in vaccum .
  • It has a very high intensity and can penetrate long distances.
  • It has a very low ionizing power. i.e. it does not ionize the medium in whic it travels.

Gamma radiation has proved itself to be very useful in radioactive treatment of cancer due to its high penetrating power.

Respiration links up the simple sugar oxygen with the gas
My name is Ann [436]

Answer:

Respiration links up the simple sugar, <u><em>glucose</em></u><em>,</em> with the gas <u><em>oxygen .</em></u>

Explanation:

In the process of respiration, oxygen is used to breakdown glucose. Water and carbon dioxide are produced due as a result of this reaction. A huge amount of energy, in the form of ATP is also released during this process. ATP is used by almost every cell of the body to carry out normal cellular functions. Energy is mainly stored in the linkage between the second and third phosphate of an ATP molecule.

Cats have a gene that codes for the color of their fur.
madam [21]
Punnet square
Let's call black 'B' and white 'b'
Being intermediate, gray cats will have the alleles 'Bb'
Being recessive, white cats will have the alleles 'bb'
          <u>       Gray  </u>
          |<u>  </u>|<u>  B   |  b |</u>
White |b|<u>  Bb | bb|</u>
          |b|<u>  Bb | bb|
</u>
^Apologies for the awful drawing XD

Bb = Gray
bb = White
So the cats can have gray or white fur (A)
