Sound waves are both compressional and longitudinal, (although we frequently draw them as transverse waves).
Longitudinal waves are where the particles of matter collide into one another, pushing them into the next and then oscillating back. This is how sound travels. This is also why sound can only travel through a medium, it cannot travel through a vacuum, as is shown here:
Answer:
Amoxicillin inhibits an enzyme required to build cell walls in bacteria.
Since humans have cell membranes, they are unaffected by amoxicillin.
Explanation:
Antibiotics are specifically designed to target bacterial cells, therefore, they don't kill human cells.
Amoxicillin, a type of penicillin, inhibits the biosynthesis of bacterial cell wall. The bacterial cell wall contains peptidoglycan that constitutes almost 95% of the cell wall in some Gram positive bacteria and as little as 5-10% of the cell wall in Gram negative bacteria. Amoxicillin inhibits the cross linkage between the linear peptidoglycan polymer chains that make up a major component of the cell walls of both Gram positive and Gram negative bacteria.
Answer:
Elbow
Explanation:
Muscle works in pairs and groups e.g biceps flexes the elbow and triceps extend it and it is called antagonistic muscle action.
The working muscle is called the primer mover or agonist. The relaxing muscle by another muscle is called synergists.
When muscles cause a limb to move through the joint range of motion,it could be synergists or antagonists.
