Protein is required for the growth and maintenance of tissues.
Enzymes are proteins that allow chemical reactions to take place within your body.
Amino acid chains of various lengths form protein and peptides which make up several of your body’s hormones and transmit information between your cells, tissues and organs.
A class is proteins known as fibrous proteins provide various parts of your body with structure, strength and elasticity.
Proteins act as a buffer system, helping your body maintain proper pH values of the blood and other bodily fluids.
Proteins in your blood maintain the fluid balance between your blood and the surrounding tissues.
Proteins form antibodies to protect your body from foreign invaders, such as disease-causing bacteria and viruses.
Hope this helps :)

Every change in a species is coded within the DNA. But the bird had lost a toe an accident. So the toe-loosing-option isn't true because not every bird looses his toe.
(Example: If a women gets bitten by a snake on the arm and gets the arm removed from her body and then in a year or so has a baby with her new husband. The baby won't be born with one arm because his/her mother lost her arm.) <span />
In this question, one parent is homozygous recessive (bbee) and other parent is dihybrid (BbEe)
B - black fur dominant trait
b - white fur recessive
E- black eyes dominant
e - red eyes recessive
a punnett square shows all the possible combinations of genotypes with the corresponding phenotypes that the offspring could inherit.
the genotypes and their phenotypes for the offspring are given below ;
BBEE / BbEe / BbEE / BBEe - black fur and black eyes
Bbee / BBee - black fur and red eyes
bbee - white fur and red eyes
bbEe / bbEE - white fur and black eyes
after analysing the punnett square the following results are obtained;
black fur and black eyes - BbEe- 4/16
black fur and red eyes -Bbee - 4/16
white fur and black eyes - bbEe - 4/16
white fur and red eyes -bbee - 4/16
I think it is D but I'm not sure, however, 4 seems pretty right.
