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:
c. Ribs move out- diaphragm contracts- lungs expand- decrease intrathoracic pressure
Explanation:
Plastics clearly constitute an important component of the range of materials used in modern society. Almost all aspects of daily life involve plastics or rubber in some form or the other. ... Owing to their light weight, plastics reduce transportation costs and, therefore, atmospheric carbon dioxide emissions./Plastic is durable and provides protection from contaminants and the elements.
Answer:
BH BH bH bH
Explanation:
I used the foil method to solve the problem
<span>Pond organism is unicellular and crab is multi cellular.
The simplest level at which life exist is called the cell. Unicellular organism contain only one cell while multi cellular organisms contain more than one cell. Multi cellular organisms can be organized into various levels such as Cells>tissues> organs>organ systems> organism. Thus pond organism is unicellular under microscope and crab is multi cellular.</span>
