General Science ASVAB Study Guide

General Science ASVAB Study Guide

• The chemical formula for water is H2O, which means it's composed of two hydrogen atoms and one oxygen atom.
• The heart is the organ responsible for pumping blood throughout the body, supplying it with oxygen and nutrients.
• Plants make their own food through photosynthesis, a process in which they convert sunlight into chemical energy.
• Food stores chemical energy, which can be converted into other forms of energy by the body.
• The mitochondria is considered the "powerhouse" of the cell, responsible for producing energy through cellular respiration.
• The Earth's atmosphere is primarily composed of nitrogen gas.
• Glucose is a simple carbohydrate, unlike sucrose, starch, and cellulose, which are more complex.
• The pH level of pure water is 7, which is neutral.
• Evaporation is the process by which a liquid changes into a gas.
• Vitamin D is primarily obtained through sunlight exposure, when the skin synthesizes it.
• The largest organ in the human body is the skin.
• Igneous rocks are formed from the cooling and solidification of magma or lava.
• Plant leaves are responsible for photosynthesis.
• DNA formation requires the element carbon.
• Red blood cells carry oxygen throughout the body.
• Photosynthesis primarily produces oxygen gas.

Prepare for the ASVAB with this comprehensive general science study guide. It covers essential concepts such as the chemical formula of water, the function of the heart, and the process of photosynthesis. Test your knowledge on topics ranging from cellular respiration to the Earth's atmosphere.
