A compound is a substance containing two or more different chemical elements bound together by what kind of bond?

48% Answer Correctly

ionic

covalent

chemical

molecular
Solution

A compound is a substance containing two or more different chemical elements bound together by a chemical bond. In covalent compounds, electrons are shared between atoms. In ionic compounds, one atom borrows an electron from another atom resulting in two ions (electrically charged atoms) of opposite polarities that then become bonded electrostatically.

5

In a eukaryotic cell, which organelles deal with proteins?

63% Answer Correctly

Golgi apparatus

endoplasmic reticulum

all of these deal with proteins

ribosomes
Solution

The nucleus of a eukaryotic cell contains the genetic material of the cell and is surrounded by cytoplasm which contains many organelles. Ribosomes produce proteins, endoplasmic reticulum helps synthesize proteins and fats, and Golgi apparatus prepares proteins for use.
