B, Magnitude of past earthquakes in the area
Answer:
Horsts and Grabens - A narrow block dropped down between two normal faults is called a graben (looks like a small valley). The upraised block is called a horst (looks like a plateau). Normal faults are the dominant structures along the oceanic ridge, and in continental rifts.
Explanation:
The answer is C. Your welcome.
The correct answer is active transport.
For this kind of transport the cell requires energy, usually in the form of ATP, to move a molecule against its concentration gradient.
There are two types of active transport:
Primary active transport which directly uses a source of chemical energy to move molecules. Example: sodium-potassium pump
Secondary active transport (cotransport), which uses an electrochemical gradient (generated by active transport)as an energy source to move molecules. Example: glucose symporter SGLT1
A team of archaeologists excavating a sedimentary rock layer come across some primitive hunting tools used by early humans. As the dig progresses, they unearth the fossilized remains of a dinosaur from another layer of the sedimentary rock. Why do these discoveries indicate that the rocks were formed over millions of years?
C) Dinosaurs became extinct millions of years before humans appeared.
