A biology student accidentally loses the labels of two prepared slides she is studying. One is a slide of an intestine, the other of an esophagus. You volunteer to help her sort them out. How would you decide which slide is which?

esophagus has stratified squamous

Explanation:

Stratified squamous is a tissue that is found covering and lining parts of the body such as the esophagus. It is known to be many layers of flattened cells.

It performs some functions like the provision of protection from abrasion, pathogens, and chemicals.

It can be found in some parts of the body like surface of skin, linings of mouth, esophagus, rectum,and vagina.

In this case, the presence of stratified squamous in a slide will definitely show that the content in the slide is esophagus. And the slides can then be easily separated and labelled accordingly.

explanation:

the sequence of amino acids in a protein determines its function. the dna sequence of a gene determines the amino acid sequence of the resulting protein. thus, any changes in dna sequence can result in changes in protein function. this is called a mutation.

i believe the correct answer is d
