Answer:

C. The model does not show the true size of an atom.

Explanation:

The model can be described or explained as a physical representation of an unseen or yet to build structure or substance. The model will show the aim of the people that want to create a thing.

In this sense, the limitation of a model is that it will not actually give you the true size of the thing it is being used to represent. This means that it won't give the through size of the atom.

Explain how the use of a chemical designed to kill grasshoppers could reduce the population of peregrine falcons.
Butoxors [25]
Peregrine falcons have a wide diet, including many types of smaller birds. These birds eat bugs like grasshoppers. So, if the grasshopper population decreases, then the birds who are a food source to peregrine falcons will also have a lower population. This means that there is a lesser amount of food for the peregrine falcons to eat, so their population will decrease as well. 

Good luck with your problems!

How many three fourths are in five halves?
marishachu [46]
To know how many \frac{3}{4} are in \frac{5}{2} we can simply divide \frac{5}{2} by \frac{3}{4}.
\frac{ \frac{5}{2} }{ \frac{3}{4} }=\frac{5*4}{2*3}=\frac{20}{6}=\frac{10}{3}

Dr. Paul Ehrlich observed that the differential stain developed by Dr. Gram suggested bacteria could be killed differentially by
Alex787 [66]

Answer:

The correct answer is Glycocalyx, ribosome and cell wall.

Explanation:

Glycocalyx is mainly found in bacteria that makes a protective covering outside the cell wall in the form of capsule of bacteria and provide protection to bacteria from host immune cell.  

Bacterial ribosomes are different from human ribosomes. Bacteria contain 70s ribosome while humans contain 80s ribosome so ribosomes are potential targets for many drugs present today.

Bacterial cell contain cell wall which is made up of peptidoglycan or lipopolysaccharide but human cell does not contain a cell wall, therefore, many drugs are designed to destroy cell wall of bacteria like penicillin.

So glycocalyx, ribosomes, and cell wall can be potential targets for Dr. Ehrlich's "magic bullets" due to significant difference or absence from humans.
