Abiochemist who is studying the properties of certain sulfur (s)-containing compounds in the body, wonders whether trace amounts of another nonmetallic element might have similar behavior. to which element should she turn her attention? ]

Explanation:

It is known that sulfur is a group 16 element. And, elements which are present in the same tend to show similar chemical properties because they contain same number of valence electrons.

As a result, they tend to show similar chemical reactivity and other similar chemical properties.

All the elements of group 16 are O, S, Se, Te, and Po.

Generally oxygen exists as a diatomic molecule or non-metal. But S and Se exists as polyatomic non-metals.

Thus, we can conclude that she should turn her attention to selenium (Se) element.

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.

space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )
