Barry is applying the principles of relative dating to a building that has been constructed. Analyzing a section of the building

, Barry says that the lowest part of the section must have been constructed the parts above it were constructed. He bases this conclusion on the principle of . Also, looking at a crack forming in the building wall, he says that the crack must be the wall. Barry used the principle of to arrive at this conclusion.

Before

Principle of superposition of strata

Younger

Principle of cross cutting

Explanation:

Relative dating is method of assigning ages to geologic events in nature. This is based on certain principles and laws proposed by earlier geologists.

Relative dating differs from absolute dating in that absolute dating assigns real quantitative numbers to geologic events.

  • From the analogy of the building provided, according to the principle of superposition of strata, the oldest layer is at the bottom of the sequence and the youngest on top.
  • The lowest part of the section must of the section must have been constructed before the parts above it were constructed.
  • Based on the principle of cross cutting "geologic features that cuts another are usually younger than the sequence they cut through ".
  • The cracks on the wall is cross-cutting feature that appeared after the wall was formed.
  • Therefore, it is younger than the wall.

Answer:

Cell division is a process that makes our skin, tissues, muscles, sex cells. It is the building block of our body.

Explanation:

When parents cells ahs been divided into two or more than two daughter cells then it is called division of cells. The division of cells occur as a larger cell. When we talk about eukaryotic cells, these cells divided into two distinct types of the cells, the vegetative cells.

The daughter cells are the identical to the parents cells genetically. There are two types of division such as mitosis and meiosis. When parents cells divides in daughter cells and daughter cells divided further, this process called the cells cycle. The mitosis cell division occur interphase. Meiosis cell division occur in two phase meiosis I and meiosis II.
