Answer: d. All the body cells arise from mitotic divisions of the same fertilized egg.
Explanation:
After conception occurs and an egg is fertilized, mitosis takes place as the egg begins to divide into other cells. This is how all the cells in the body are eventually formed regardless of how specialized their roles are.
As a result, every cell in the human body shares the same genes so any biological liquid or structure of the body would indicate the criminal because they would share the same gene as the rest of the cells in the criminal.
The meselson-stahl experiment demonstrated that dna replication produces two DNA molecules each composed of the nitrogen isotopes.
<h3>
What was the conclusion of the meselson-stahl experiment?</h3>
Based on observations and experimental results, Meselson and Stahl concluded that DNA molecules can reflect semi-conservatively. Investigation of semi-conservative nature of replication of DNA or the copying of the cells, DNA failed to cease there.
1958, Matthew Meselson and Franklin Stahl carried out an test on E. coli which divides in 20 minutes, to take a look at the replication of DNA. 15N (heavy) and 14N (normal) are isotopes of nitrogen, which may be outstanding primarily based totally on their densities through centrifugation in Caesium chloride (CsCl).

When the body is in the ""normal anatomical position" it refers to as hominid anatomy.
- The body is referred to as being in what is known as the typical anatomical position when discussing hominid anatomy.
- The typical anatomical stance for a human is standing with their feet together and pointing forward, without any long bones being crossed from the observer's point of view.
- Human anatomy and physiology can be explained in a straightforward and consistent manner using standard anatomical positions.
- Many anatomical terminology are used to describe the relative placement of different appendages in relation to the standardized position while analyzing an individual's anatomy.

Hope this helped! This is called a punnett square, it calculates the percentages of phenotype outcomes. Some are more difficult than others, but this is pretty basic, just be sure to study about this.
Yes art is universal because most pieces use images, colors, and shapes to convey meaning so anyone from any part of the world can find the hidden meaning.
