The energy posessed by a thrown baseball is an example of what kind of energy?
potential |
|
gravitational |
|
kinetic |
|
transitional |
Kinetic energy is the energy posessed by a moving object. Potential energy is stored energy in a stationary object based on its location, position, shape, or state.
Which of these represents the path of blood flow through the heart?
right atrium → left ventricle → lungs → left atrium → right ventricle |
|
left atrium → right ventricle → lungs → left atrium → right ventricle |
|
left atrium → left ventricle → lungs → right atrium → right ventricle |
|
right atrium → right ventricle → lungs → left atrium → left ventricle |
To provide oxygen to the body, blood flows through the heart in a path formed by the right atrium → right ventricle → lungs → left atrium → left ventricle → body. When blood enters the right side of the heart it is deoxygenated. It enters the left side of the heart oxygenated after traveling to the lungs.
Which of the following indicates the correct reproductive sequence?
ovum → fetus → zygote |
|
zygote → ovum → fetus |
|
none of these are correct |
|
ovum → zygote → fetus |
During intercourse, the penis ejaculates sperm, produced in the testes, into the vagina. Some of the sperm makes their way to the uterus where, if they encounter an egg to fertilize, unite with the ovum to form a fertilized egg or zygote. The zygote then may implant in the uterus and eventually develop into a fetus.
What kind of weather front is likely to create clouds and storms?
temperate front |
|
warm front |
|
stationary front |
|
cold front |
A warm front is the boundary between warm and cool (or cold) air when the warm air is replacing the cold air. Warm air at the surface pushes above the cool air mass creating clouds and storms.
Which is the proper order of Earth's atmospheric layers from the surface up to space?
stratosphere, troposphere, mesosphere, thermosphere |
|
mesosphere, thermosphere, stratosphere, troposphere |
|
thermosphere, mesosphere, stratosphere, troposphere |
|
troposphere, stratosphere, mesosphere, thermosphere |
The troposphere is the closest layer to Earth, followed by the stratosphere, mesosphere, and finally the thermosphere which borders space.
