D. The number of electrons equals the atomic number for a neutral element. Each number after the letter refers to the number of electrons in that shell. So for D, 2+2+6+2+6+2 = 20 electrons, which is equal to the atomic number.
Cytoplasm: gel like environment which allows organelles to move about the cell
Golgi bodies: packages and ships materials out of the cell
Cell membrane: controls what goes in and out of the cell
Chloroplast: makes food for plant cells using sunlight
Lysosome: breaks down waste, food, and worn out cell parts
Mitochondria: breaks down food to release energy for the cell
Nucleus: contains the cell's DNA and is the control center of the cell
Endoplasmic reticulum: transports materials within cell; process lipids
Vacuole: stores water, waste and food
Ribosome: make proteins
Answer: B. Chemists are constantly learning more about what makes chemicals dangerous.
Explanation: The safety of chemicals still remains of utmost importance as chemist haven't relented in their strive and curiousness at knowing the compounds, mixtures and elements which makes chemicals dangerous in other to minimize or mitigate the risk of exposure to this chemicals during usage. Chemicals are things we cannot do without as they constitute a lot to the human race in terms of Energy and health. Due to this immense contribution, the safety of chemicals will remain of great priority to chemists.
