Molecules and atoms that are outputs from a chemical reaction are known as which of the following?
results |
|
reactants |
|
products |
|
side effects |
During a chemical reaction molecules and atoms (reactants) are rearranged into new combinations that result in new kinds of atoms or molecules (products).
The connective tissue that connects bones to other bones at joints is called:
tendons |
|
cartilage |
|
ligaments |
|
knuckles |
Tough fibrous cords of connective tissue called tendons connect muscles to the skeleton while another type of connective tissue called ligaments connect bones to other bones at joints (elbow, knee, fingers, spinal column).

scavengers |
|
primary consumers |
|
secondary consumers |
|
tertiary consumers |
Primary consumers (herbivores) subsist on producers like plants and fungus. Examples are grasshoppers, cows, and plankton.
Water has a refractive index of 1.33. Which of the following is true?
light is 1.33 times brighter in a vacuum than it is in water |
|
light travels 1.33 times slower in a vacuum than it does in water |
|
light travels 1.33 times faster in a vacuum than it does in water |
|
light is 1.33 times dimmer in a vacuum than it is in water |
The speed of light varies based on the material that the waves are passing through. The refractive index of a material indicates how easily light travels through it compared to how easily light travels through a vacuum. For example, the refractive index of water is 1.33, meaning that light travels 1.33 times faster in a vacuum than it does in water.
Molecules and atoms that are inputs to a chemical reaction are known as which of the following?
components |
|
reactants |
|
fuel |
|
products |
During a chemical reaction molecules and atoms (reactants) are rearranged into new combinations that result in new kinds of atoms or molecules (products).
