10. Julie has red hair, while Billy has brown hair,
Explain how differences in their chromosomes can account for this difference in appearance
The difference in the chromosomes can account for this difference in appearance, as hair color is caused by of DNA strand contained in the chromosome.
What are chromosomes?The hereditary material that makes up chromosomes is arranged in x shapes inside the nucleus. DNA, genes, and proteins make it up. An organism's genotype is distinct from other organisms because of its distinct genetic makeup, and this distinction can be passed down from one generation to the next.
Julie's red hair is caused by one allele or a combination of alleles in a gene. Billy's hair is brown because he possesses an alternate allele or set of alternate alleles for this gene.
Therefore, the base pair order along the sections of DNA that code for hair color is different in Julie and Billy's DNA.

ID: 532164
Hint
The answers are A B and C according to my sources…
An oceanic tectonic plate in the eastern Pacific Ocean basin off the west coast of South America is called the Nazca Plate, sometimes known as the Nasca Plate, after the Nazca region of southern Peru. Thus option A, B, C is correct.
What tectonic plate off the coast of the western US?The continent of North America is located on the oceanic plate to the east, while the Pacific Plate is the oceanic plate to the west. However, in the geologic past, there was another oceanic plate to the west known as the Farallon plate.
The triple junction will continue to be defined by the western margin of the North American plate along the Cascadia Subduction Zone as the boundary between the two plates.
Therefore, The Pacific Ocean is deeper than the other oceans of the world and the ocean levels are rising along the western coastline.

4. Which of the following is NOT a tenant of the Cell Theory?
a. All cells(come from existing cells.
b. All living things are made of cells.
C. Cells are the basic units of structure and function.
d. All cells contain a nucleus.
Answer: b. All living things are made of cells.
Explanation:
A cell is the smallest basic unit of life that is capable of independent functionality. A cell therefore cannot be made up of other cells because that would imply that there is a unit of life that is smaller than cells.
Cells are instead made up of organic molecules like protein and carbohydrates and when cells work together to achieve a common goal, they form a tissue. Tissues are the ones made up of cells not cells made up of other cells.
