Harlamova29_29 [7]3 years ago
8 0

Answer:

Genetic variations that alter gene activity or protein function can introduce different traits in an organism. If a trait is advantageous and helps the individual survive and reproduce, the genetic variation is more likely to be passed to the next generation (a process known as natural selection)

Question 10
stich3 [128]

Answer:

<h2>Its true!!</h2>

Explanation:

Actually the haemoglobin molecule consists of 2 parts, the haem which is a prosthetic group and the other globin which is a protein. So the haemoglobin as is a protein so, is arranged in quaternary structure of protein which contains 4 subunits. The subunits depend upon the organism whose haemoglobin is being talked about. So the normal haemoglobin found in red blood cells contains 2 alpha subunits + 2 beta subunits. At the centre of each subunit there is the haem part attached. To the centre of haem the Fe3+ ion are present which actually attaches to 1 Oxygen molecule. So as 4 subunits are present and each subunit has 1 Fe3+ ion, so total 4 Oxygen molecules can bind to the 1 Hb molecule!!

  • Also, the punnet square is used for a single factor and this is known as a monohybrid cross.
  • They show all genotypes that can result from crosses.
  • A punnet square is used for statistically establishing the likelihood of a set of gene to form and dominate.
