Answer: D.finding fossils in the same area that are in layers closer to the surface.
Relative dating refers to the age estimation method in which past events are determined, to compare the age of object, organism, strata or rock with the age of other similar entity. This method gives an approximate or estimated age, it does not provide absolute age.
The older fossils are found in deeper layers of the strata as compared to younger fossils. This represents the geological time and life span of primitive or preexisting organisms. Therefore, according to the given situation, finding fossils in the same area that are in layers closer to the surface is the best conclusion.
Answer: C
Proof: This would be C because radioactive decay is when atoms and protons decide to slowly decay or separate from the atom. Therefore, they would produce radiation. Just like atomic bombs or nuclear waste. (Hope this helps-)
Explanation:
Each chromosome pair consists of one chromosome inherited from the mother and one from the father. ... Arranged on the chromosomes are genes.
<span>The correct answer is b. Option a is incorrect because these models can demonstrate scientific theories, but they don't prove scientific theories (you would need experiments for that). Option c is incorrect because the models aren't always representing something abstract (i.e. DNA is very real, just very small). Option d is incorrect because they don't precisely mimic something in nature, but instead help us visualize something in nature that is difficult to see or comprehend.</span>
Answer:
Laboratory Supervisor/Principal Investigator.
Explanation:
The biohazard may be defined as any biological substance that can create problems for the living organisms. The substance can be either any bacteria, virus or any toxin.
The individual if working with any biohazard must read carefully and than start their work. This is the duty of principal investigator or the laboratory supervisor that they should include and show the written assessment of the experiments that might acts as biohazard.
Thus, the answer is Laboratory Supervisor/Principal Investigator.
