The four laws or principles that are involved with the study of Stratigraphy are the following:
1. Principle of original horizontality
2. Law of superposition
3. Law of crosscutting relationships
4. Principle of Lateral Continuity
5. Principle of Faunal Succession

Therefore, the correct answers would be 1, 2 and 4. Hope this answer helps.
A karyotype is a picture in which the chromosomes of a cell
have been stained so that the banding patterns of the chromosomes appear. This
way it is possible to view abnormalities in the chromosomes. Disorders such as aneuploidy can be diagnosed by karyotype.
It can also help identify local abnormalities on chromosomes such as abnormalities
in chromosome length, and location of the
centromere.
I would say <span>C. being injected into the cell is the right answer</span>
Rickets is a disease of growing bones. Consequently, it usually is seen in young, weaned, growing pigs in which there is a deficiency, an imbalance, or a failure of utilization of calcium, phosphorous or vitamin D. Rickets usually is caused by a dietary deficiency of vitamin D or phosphorus. And Osteoporosis a medical condition in which the bones become brittle and fragile from loss of tissue, typically as a result of hormonal changes, or deficiency of calcium or vitamin D. More than 10 million Americans have osteoporosis, but most do not realize that they have it.
One of the big differences is one occurs mostly to pigs and the other effects adults.Another difference is one occurs while the bones are growing and the other happens after the bones are already grown. I hope this helps!!!
