Answer the following question given this paragraph: Chemical energy that organisms need comes from food. The nearly universal food for life is the sugar glucose. Glucose is a simple carbohydrate with the chemical formula C 6 H 12 O 6 . The glucose molecule stores chemical energy in a concentrated, stable form. In your body, glucose is the form of energy that is carried in your blood and taken up by each of your trillions of cells. Q: Where is glucose carried in the human body? Choices: - the liver - the brain - the heart - the blood A:
the blood

Answer the following question given this paragraph: Earth's atmosphere is vital to life. The atmosphere provides the oxygen and carbon dioxide living things need for photosynthesis and respiration. Living things also need the ozone layer high in the atmosphere. Upper level ozone protects them from most of the Sun's harmful UV rays. Q: What layer high in the atmosphere protects living things from most of the sun's harmful uv rays? Choices: - Mesosphere - troposphere - stratosphere - ozone layer A:
(Answer)
ozone layer

(A).
neutrons
Ques:Answer the following question given this paragraph: When the number of electrons and the number of protons are equal, the object is neutral. Q: When the number of electrons and the number of protons are equal, the object is what? Choices: - Negative - Positive - static - neutral A:

Ans:neutral
Answer the following question given this paragraph: Electron configuration notation eliminates the boxes and arrows of orbital filling diagrams. Each occupied sublevel designation is written followed by a superscript that is the number of electrons in that sublevel. For example, the hydrogen configuration is 1 s 1 , while the helium configuration is 1 s 2 . Multiple occupied sublevels are written one after another. The electron configuration of lithium is 1 s 2 2 s 1 . The sum of the superscripts in an electron configuration is equal to the number of electrons in that atom, which is in turn equal to its atomic number. Q: The sum of the superscripts in an electron configuration is equal to the number of electrons in that atom, which is in turn equal to what number? Choices: - metallic number - shell number - orbital number - atomic number A:
atomic number
