Answer:
The answer is D: The hormone is released into the bloodstream where it can be transported to all cells with the correct receptors.
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.
Answer:
The 3 major observations were:
1. More individuals are produced each generation that can survive.
2. Phenotypic variation exists among individuals and the variation is heritable (through parents' genes).
3. Those individuals with heritable traits better suited to the environment will survive.
Explanation:
Charles Darwin was a British naturalist who proposed the theory of known to everyone as 'The Theory of Evolution' through natural selection.
Answer:
1/4 WR; 1/4 wr; 1/4 wR; 1/4 Wr
Explanation:
The principle of independent assortment indicates how different genes independently separate from one another when gametic (reproductive) cells develop. When a cell divides by meiosis, homologous chromosomes are randomly distributed to daughter cells, thereby different chromosomes segregate independently of each other. In consequence, each gamete has a unique combination of chromosomes. In this case, the two genes are on different homologous chromosomes, thereby gene variants (alleles) will be randomly distributed to daughter cells during meiosis (anaphase I) and thus the expected proportion of gamete genotypes will be 1/4 WR, 1/4 wr, 1/4 wR, 1/4 Wr.
