Scavengers break down the dead bodies of plants and animals into which of the following?
simple nutrients |
|
producers |
|
carrion |
|
complex carbohydrates |
Like decomposers, scavengers also break down the dead bodies of plants and animals into simple nutrients. The difference is that scavengers operate on much larger refuse and dead animals (carrion). Decomposers then consume the much smaller particles left over by the scavengers.
Respiration is the process by which __________ absorb oxygen and eliminate carbon dioxide.
bronchioles |
|
blood cells |
|
capillaries |
|
diaphragms |
The respiratory system manages respiration which is the process by which blood cells absorb oxygen and eliminate carbon dioxide.
A subatomic particle found in the nucleus of an atom. It carries a positive electric charge. This desribes which of the following?
electron |
|
neutron |
|
proton |
|
atom |
A proton is a subatomic particle found in the nucleus of an atom. It carries a positive electric charge.
Velocity is the rate at which an object changes position. What is the formula for velocity?
none of these |
|
\(\vec{v} = \vec{d}t \) |
|
\(\vec{v} = { t \over \vec{d} } \) |
|
\(\vec{v} = { \vec{d} \over t } \) |
Velocity is the rate at which an object changes position. Rate is measured in time and position is measured in displacement so the formula for velocity becomes \(\vec{v} = { \vec{d} \over t } \)
The energy posessed by a thrown baseball is an example of what kind of energy?
transitional |
|
potential |
|
gravitational |
|
kinetic |
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.
