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.
Hello there :)
I am quite sure this is a true/false question
This statement is false.
Yes, the cilia and mucus in the trachea does sweep upward, however, it moves the mucus towards the pharynx where it is swallowed not towards the nose where it is sneezed out.
Mitochondria are thought to have evolved from ancient bacteria. Free-living bacteria have lost motility in mitochondria over time.
<h3>What is endosymbiosis?</h3>
- Endosymbiosis is the term used when one organism truly lives inside the other. According to the endosymbiotic theory, it is simple for a big host cell and ingested bacteria to become dependent on one another for survival and develop a long-term bond.
- Due to their increased specialization through millions of years of evolution, mitochondria and chloroplasts can no longer survive outside of cells.
- Chloroplasts and mitochondria are remarkably similar to bacterial cells. They have unique DNA that is distinct from the DNA found in the cell's nucleus.
- Additionally, these organelles synthesize numerous proteins and enzymes necessary for their functions using DNA. Both mitochondria and chloroplasts are surrounded by a double membrane, which is additional proof that each was ingested by a primitive host.
- Similar to bacteria, the two organelles also divide by themselves and replicate their own DNA.

Answer:
A
Explanation:
If one object attracts another object, it causes the second object to move towards it. Anything with strong gravity attracts other things to it.
