Answer:
relative and absolute dating
Explanation:
Two methods of dating fossil fuels are -
a) Relative Dating and b) Absolute Dating
a) Relative Dating - In this method, unknown age of fossil A is determined by comparing it with the known age of fossil B via correlation . Such " fossils B" are known as index fossils. These index fossils belong to a specific age group.
Some common example of index fossils are -
brachiopods,
trilobites, and
ammonites
b) Absolute Dating - In this method, the age of rock is determined through radiometric dating methods. Here, instead of dating the fossil itself, the rock or volcano layer above and below the fossil is dated for determining a rage of date.
b. False
A high birth-to-death ratio leads to larger populations. This is because the birth rate is the number of births per 1,000 people in a population, and the death rate is the number of deaths per 1,000 people in a population. Hence the statement is false.
If the birth rate is higher than the death rate, then the population will grow. On the other hand, a low birth-to-death ratio leads to smaller populations. This is because the birth rate is lower than the death rate, so the population will shrink.
Therefore, the statement "A high birth-to-death ratio leads to larger populations, not smaller populations." is False.

B) Electrons are being moved from atoms that have a lower affinity for electrons (such as
C) to atoms with a higher affinity for electrons (such as O).
C) The oxidation of organic compounds can be used to make ATP.
D) The electrons have a higher potential energy when associated with water and CO₂ than they do in organic compounds.
E) The covalent bond in O₂ is unstable and easily broken by electrons from organic molecules.
B. A chemical in the birds food produces the red coloring
C. What does the scarlet ibis eat?
D. The feathers are red because a wizard cursed the bid long ago
The hypothesis for what causes a scarlet ibis to have red feathers is that a chemical in the bird's food produces the red coloring.
B. A chemical in the bird's food produces the red coloring. In this case, the hypothesis suggests that the red feathers of the scarlet ibis are caused by a specific chemical component present in the bird's food. This hypothesis can be tested by conducting experiments to analyze the bird's diet and investigating the effects of different foods on the coloration of the feathers.

in the Rocky Mountains
under the Missouri River
inside the Grand Canyon
The thickest part of the earth’s crust is under mountains. Whenever there is a volcanic eruption, more material is poured out on the earth’s surface from under the crust, so as the years pass the earth’s crust is increasing slowly.
The area of Rocky Mountains is where the earth’s crust would be expected to be thickest.
Answer: In the Rocky Mountains.
I hope this helps, Regards.
