Answer:
The seafloor is only 180 million years old due to the process of subduction. The floor of the sea's tends to get colder and denser with the passage of time. At a certain time, the seafloor becomes so dense that it sinks in the upper mantle. The Earth's crust cannot undergo this process and hence has oldest rocks. We can say that the seafloor is less than 180 million years old because it is typically recycled back into the mantle of the Earth.

Fast Facts: Lipids
- A lipid is any biological molecule that is soluble in nonpolar solvents.
- Lipids include fats, waxes, fat-soluble vitamins, sterols, and glycerides.
- Biological functions of lipids include energy storage, cell membrane structural components, and signaling
There are many different types of lipids. Examples of common lipids include butter, vegetable oil, cholesterol and other steroids, waxes, phospholipids, and fat-soluble vitamins. The common characteristic of all of these compounds is that they are essentially insoluble in water yet soluble in one or more organic solvents.
False
Answer:
The population with the greatest genetic variation may have:
- The greatest number of alleles per gene
- The largest gene pool
Explanation:
A higher number of alleles will produce a higher total number of protein forms per gene. Moreover, the largest gene pool will synthesize the largest content of proteins, thereby increasing variation
