According to the question, the width of a pin is 0.001m and the width of a red blood cell is 6-8 μm.
Width of pin in μm = 1000μm.
So approximately 1000/8 red blood cells can fit which is equal to 125 RBCs.
Answer: 125 RBCs
Answer:
Both are considered macromolecules. I'll explain below
Explanation:
Proteins are like a huge Lego construction. Each individual piece gets pieced together to make a larger "thing" - Death Star, House, etc. Each individual piece is a monomer, and the larger construction is the polymer. The monomers are Amino Acids and they get pieced together to form the polymer that is called a protein. The linkage that they use is an amide bond, and in biology it is usually called a peptide bond.
Carbohydrates can be singular monomers or polymer units. They are made of completely different compounds - usually aldehydes or ketones. And they link together through different chemical linkages (acetal or ketal linkages for polymers,hemiacetal or hemiketal linkages for monomers).
Both can be large, 3D strucutres - proteins are only functional as a large, 3D structure, while carbohydrates can be singular.

I believe it is B, direct contact
Explanation:
Ali most likely wasn't eating food that the dog had contaminated, nor was it likely that a mosquito first bit the dog and then Ali. This leaves A and D, and A seems to be more likely.
Apologies if I am incorrect.
A CONSUMER gains its energy by eating something else.
