It's B
Explanation:
Because the fossil record shows how organisms have evoluate from relatively simple organisms to more complex organisms
Explanation:
When you make the cross. You get
HH HH Hh Hh.
So the genotypic ratio - 2:2 which is also 1:1.
The phenotypic ratio - 4. Since Hh and HH are horned organisms. So they only differ in their genotypic make up.
Answer:
yes
Explanation:
It depends upon the fertility of the bird.When a poultry bird is raised the farmer provides the bird with food supplement with other vitamins and some leafy vegetables.This enables the good growth and fertility rate and capability is increased through it.Hence,A poultry bird can lay more eggs in a day.

Answer:
Troponin
Explanation:
This is a complex of three proteins (Trop C, I, T) that are responsible for muscle contraction of the skeletal and cardiac muscles . its binds with protein tropomysin to lie in the grove between the actin filaments. its prevents contraction by blocking myosin crossbridge in a relax muscles.Inorder to aid contractions calcium ions binds with troponin, which leads to confrontational change.This exposes myosin on actin filaments, leading to formation of crossbridge and therefore contraction of muscles.
Therefore if there is a mutation in the gene that encoded Troponin, as explained above, calcium ion will not be able to bind with tropinin, and there will be no exposure of myosin on actin filaments, no binding of myosin on actin to cause crossbridge, and consequently no muscle contraction,
Thus the intercoastal muscle and diaphragm will not contract leading to death of the baby.
