Answer:
A trio of antibiotics that had become powerless against MRSA decades ago proved effective in infected mice when used together.
Although more testing is needed, the results suggest that combinations of already-approved antibiotics might add to our options to combat MRSA infections.
Explanation:
Ans.
The codons show genetic codes, made up of triplet of nucleotides in DNA or RNA that code for specific amino acids. The different codes can code for a same a amino acid. When a substitutional mutation occurs in genetic material, it shows substitution of one nucleotide pair for another and leads to formation of a different codon.
The first mutation that leads to CAU to CAC, it will not show any potential damage as both CAU and CAC codons code for histidine amino acid.
The second mutation that leads to UGU to UGC will also not show any damage to protein as both of these codons code for cysteine amino acid.
The third codon, that results UCU to UUU will cause a potential damage to protein as UUU codes for phenyl alanine (an aromatic, non-polar amino acid) and UCU codes for serine (a polar amino acid).
Thus, the correct answer is 'option C).' as in a protein, substitution of serine with phenylalanine will lead to change in structure and function of that protein.

Explanation:
The skeletal system
The skeletal system works as a support structure for your body. It gives the body its shape, allowing movement.
Answer:
The correct order would be:
Water evaporates from a lake.
↓
Water vapor condenses to form clouds.
↓
Water falls as rain, snow, and sleet.
↓
Water flows down mountains and hills.
↓
Water joins streams or forms groundwater.
Water cycle refers to the cyclic movement of water in an environment. The water passes through various stages, namely:
evaporation and transpiration
condensation
precipitation
run off
