Examples of tertiary consumers include:
cows |
|
chickens |
|
fish |
|
sharks |
Tertiary consumers eat primary consumers and secondary consumers and are typically carnivorous predators. Tertiary consumers may also be omnivores. Examples include wolves, sharks, and human beings.
In cell biology, the primary difference between anaerobic and aerobic respiration is that aerobic respiration requires:
water |
|
mitochondria |
|
oxygen |
|
sugar |
Some plant cells produce their own energy through photosynthesis which is the process by which sunlight, carbon dioxide, and water react to make sugar and oxygen. Animal cells cannot produce their own energy and, instead, generate energy when mitochondria consume outside sugar and oxygen through aerobic respiration.
50°F is how many °C?

The formula to convert from F° to C° is:
\(C° = {5 \over 9} (F° - 32)\)
plugging in our values gives:
\(C° = {5 \over 9} (50 - 32)\)
\(C° = {5 \over 9} (18)\)
\(C° = {90 \over 9}\)
\(C° = 10\)
Atoms of an element whose atoms can vary in the number of neutrons in their nucleus are called which of the following?
ions |
|
products |
|
reactants |
|
isotopes |
The atomic mass of an element listed in the Periodic Table represents the average mass of a single atom of that element and is measured in atomic mass units (amu). This number is an average as some elements have isotopes with atoms that vary in their number of neturons and, therefore, differ in weight.
Work is measured in:
watts |
|
joules or newton-meters |
|
horsepower |
|
amps |
Work is performed on an object when an applied force causes displacement along the same vector. Measured in joules (J) or newton-meters (Nm), work is calculated by multiplying force times displacement: \(W = \vec{F}\vec{d}\)
