Answer:
Stratified squamous epithelium
Explanation:
Most animals, including humans, have stratified squamous epithelium in their esophagus. It may include keratin, which gives an extra layer of protection, allowing them to eat bigger and less chewed food. It should be noted that the esophagus has a mucous membrane and because of the muscular layers, called muscularis mucosae, the food can pass rapidly through it preventing damages in its layers due to coarser or abrasive food.
Answer:
<em>A: Multiple genes contribute to human height</em>
Explanation:
What Mendel observed in pea plants is generally considered to be exceptions to what is obtainable in most living organisms. Instead of segregating and assorting independently, a lot phenotypic expressions are as a result of interaction of several genes on different loci (polygenic inheritance) while in some cases, multiple phenotypic expressions are controlled by a single gene.
Human height is a continuously varying character and has been studied to be controlled by multiple genes. In addition, the human height is often a result of complex interaction between genetics and the environment.
The correct answer is A.
