Hello there!

The principle of diffusion consists in the movement of substances through a membrane from a zone with high concentration, to a zone with low concentration, until the concentration is equal on both sides of the membrane. 

An example of diffusion is the process that happens when we breathe. Two substances in the body that will move based on the principles of diffusion are Carbon Dioxide and Oxygen. Carbon Dioxide will move from the bloodstream to the alveoli, and Oxygen will move from the alveoli to the bloodstream.

=1/4

=0.25 × 100%

=25%

Explanation:

If two heterozygous individuals have a child

i.e let the heterozygous individuals be  = Xy

if both traits crosses together; their F₁ offspring will be;  (XX, Xy, Xy, yy)

Xy  ×   Xy

          X             y

X        XX          Xy

y       Xy            yy

Different forms of a given gene are known as
yulyashka [42]

Answer: alleles

Explanation:

Alleles are different forms of a given gene. Alleles are mutated forms of a given gene which controls a particular trait. For instance, the gene that codes for hemoglobin is denoted with the letter A but the gene has another variant denoted by S. In abnormal hemoglobin S (sickle hemoglobin), glutamate is replaced by valine at position 6 in the amino acid sequence of the two beta chains of hemoglobin. This change in the amino acid sequence causes the red blood cells to have a sickle shape resulting in sickle cell disease. Therefore hemoglobin A and S are alleles of a given gene.
