Which of the following is the narrowest classification of life?
species |
|
domain |
|
family |
|
genus |
The narrowest classification of life, species, contains organisms that are so similar that they can only reproduce with others of the same species.
DNA is encoded through a combination of which of the following?
helix |
|
genes |
|
nucleotides |
|
gametes |

When the clouds become too saturated with water, the water is released as precipitation in the form of:
rain |
|
snow |
|
ice |
|
snow or ice |
Rising into the atmosphere, the water condenses into clouds. When the clouds become too saturated with water, the water is released as snow or ice precipitation which may warm as it falls to reach Earth as rain.
"The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object." This describes which of Newton's laws of motion?
first |
|
second |
|
third |
|
fourth |
Newton's second law of motion states that The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object. This law basically means that the greater the mass of an object, the more force is needed to overcome its inertia.
