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.
Cladograms are concerned with the way organisms are related to common ancestors through shared characteristics. Phylogenetic trees compare organisms over evolutionary time and the amount of change that has occurred over time to figure out the relationships.
7 cus the circle is males
answer:
this is the cell theory, which was proposed by Theodor Schwann in 1839
explanation:
- in biology, cell theory is the historic scientific theory
- it states that living organisms are made up of cells, they are the basic structural/organizational unit of all organisms and all cells come from pre-existing cells.
