The caterpillar crawls with its front four legs and holds onto objects to move around with its back two. When a caterpillar goes into metamorphosis, it sheds what is called the old skin or exoskeleton which… Continue reading How Many Legs Does A Caterpillar Have?
Brain imaging techniques are a form of medical imaging which uses various technologies to produce pictures of the brain. There are many different types, each with its own strengths and weaknesses. One technique that does not collect information about brain functioning is computed tomography (CT). CT can take cross-sectional images but it cannot create 3D… Continue reading Which of the following imaging techniques does not collect information about brain functioning?

Magnesium is a chemical element with the symbol Mg. It has 12 protons and 12 electrons, but there are actually 14 neutrons in magnesium. This is because it has two extra isotopes that have neutron numbers of 3 and 4 each. How do you find the number of neutrons in magnesium? You can calculate this… Continue reading How Many Neutrons Does Magnesium Have?
Nitrogen is a chemical element in the periodic table that has an atomic number of 7, and its symbol is N. It was discovered by Daniel Rutherford in 1772. Nitrogen gas makes up 78% of Earth’s atmosphere and about 20% of the air we breathe. Nitrogen is used to make ammonia which can be used… Continue reading How Many Neutrons Does Nitrogen Have?
What is momentum? In physics, the term “momentum” refers to the quantity of motion in a given body. Momentum changes when an outside force acts on it. There are three factors that affect an object’s momentum: external forces such as gravity or friction, internal forces within the object itself (such as the atomic bonds between… Continue reading When a constant force acts on an object what does the object’s change in momentum depend upon?
If you are looking to find the number of protons, electrons, and neutrons in Sodium, then this post is for you! We will go through a brief explanation of what they are and how to find them. To start off with, it is important to know that there are two types of atoms: hydrogen-1 or… Continue reading How Many Protons Does Sodium Have?
