The answer is 22.5 lb/gal.
The density of a liquid is quotient of mass and volume: D = m/V. The unit of the density is pound per gallon (lb/gal)
The density is unknown: D=?
But, we have:
mass: m= 90 lbs
volume: V = 4 gals
Do, the density of a liquid is:
D = 90 lbs / 4 gals
D = 22.5 lb/gal
This happens due to geologic uplift and the erosion of the rock and soil above them. At the surface, metamorphic rocks will be exposed to weathering processes and may break down into sediment. These sediments could then be compressed to form sedimentary rocks, which would start the entire cycle anew.
The few dandelions developed a resistance to the herbicide and the herbicide would not be effective in the control of future generations of dandelions because the future generations would be offspring of the resistant strain of dandelions which means the herbicide wouldn't have an effect on them. This principle has become a concern in the world of farming with the introduction of agent orange corn and round up ready GMOs. These GMOs have their genetic code altered to become resistant to their respective herbicides viz. Agent Orange and Round Up. If weeds were able to somehow be able to get thst gene. There would be problems
Answer: Cells contain protein, and viruses contain only carbohydrates. Cells reproduce independently, and viruses require a host to reproduce.
Explanation:
It spanned 4.059 billion years.
So it is none of the above.
