Answer:

Option C, from the bottom of the meniscus

Explanation:

The meniscus in a graduated cylinder represents the volume of the liquid being measured

The prime aim is to take the reading at the center of the meniscus whether it takes concave shape or convex shape

In case of water, the reading is taken from the bottom of the meniscus and in case of mercury the reading is taken from the top of the meniscus.

However, except mercury in most of the cases the reading is taken from the bottom of the meniscus. Hence, option C is correct

If we imagine that plant has two alleles for the trait and if P represents dominant allele, and p represents recessive allele, then genotypes are:
PP - dominant homozygous, which contains both dominant alleles
pp - recessive homozygous, which contains both recessive alleles
Pp - heterozygous, which contains both dominant and recessive alleles

What geologic event most likely caused the folding and faulting of these layers?

kotegsom [21]

Answer:

Folding and faulting- The process in which the layers of the Earth are displaced or moved into a different position due to some forces acted upon them, as there are different reasons due to which the folding and faulting occurs.

The forces are so power full that they can bring the sediments of ocean to level or elevation above the sea level and can have a destructive effects for the living being. As there are various causes for folding and faulting of these layers,some of these forces are given below;

Explanation:

Geological events causing the folding and faulting-

Tectonic Plates movement- The parts of the Earth layer are always sliding over each other, and when they do they produce huge seismic waves. Which then causes the earthquakes, the folding and faulting of these layers.

Volcanic eruptions : It happens rarely as the number of gases and lava from inside the Earth, down from the crust move upward and erupts, producing dust in the atmosphere.

The other two geological causes are;

Intrusive igneous activity,
subduction.
