Answer:
Length of the real cells = 7500 cm
Explanation:
A scale model is a physical representation of an object that has the same aspects as that of the object.
A scale model can be used in fields like engineering, film making, salesmanship, etc
Length of the student's cell model = 15 cm
The scale is 
So,
Length of the student's cell model / Length of the real cells = 
15 / Length of the real cells = 
Length of the real cells = 15 × 500 = 7500 cm
The electron transport chain (etc) pump protons out of the mitochondrial matrix and into the space between the membranes because the electrons are passed to oxygen, which combines with protons to form water
<h3>What is mitochondrial matrix ?</h3>
The tricarboxylic acid (TCA) cycle, a chain of metabolic events started when pyruvate and fatty acids are converted to acetyl coenzyme A, takes place in the mitochondrial matrix (acetyl-CoA). Membrane-bound permeases move pyruvate and fatty acids from the cytoplasm into mitochondria.
<h3>What is electron transport chain?</h3>
A succession of protein complexes and other molecules form an electron transport chain when they work together to transmit protons across a membrane while also transferring electrons from electron donors to electron acceptors via redox processes. Several proteins are found in the mitochondria's inner membrane.

Nucleotides are the building blocks of DNA macromolecules
In order to cope in times where normalcy is not present, methods such as social distancing, masks, and sanitation are incredibly important.
Answer:False they re not the same
Explanation:
Evolution is not the same as adaptation or natural selection. Natural selection is a mechanism, or cause, of evolution. Adaptations are physical or behavioral traits that make an organism better suited to its environment. Heritable variation comes from random mutations.
