A very important fact to be considered about fossils by scientists is the Age of the Fossil. This is found by Carbon Dating. The reason why the age is of high importance is because it determines during what time the fossil lived and how it is evolution.

Answer from: babyraerae06

Knowing the age of the fossils is the most important factor for the scientists that study evolution.

The age of the fossils is found out with the help of objective and radioactive dating. The fossils themselves generally cannot be dated directly, as the majority of them have no or less of the organic substance left in it, and dating with carbon 14 is only beneficial up to the age of 35000 to 50000 years.

However, with the application of radiometric dating, the scientists are able to put an objective date. By determining the concentration of radioactive decay in specific elements since the solidification of the igneous rocks, one can find out the exact date of the fossil.

The most generally used elements for radiometric dating of rocks are uranium, argon., potassium, and rubidium as they exhibit fairly long half lifes.

Answer from: Quest

hey, i believe your answer would be d. sugar ribose and the base uracil. i believe this is the answer, because rna consists of sugar ribose, adenine, guanine, cytosine, and uracil.

your first option is incorrect, because that's dna. where it consists of sugar deoxyribose, adenine, guanine, cytosine and thymine.

your second option is also incorrect, this is because sugar deoxyribose is in dna, and uracil is in rna. these two do not make sense together.

your third option being incorrect, because sugar ribose is in rna, but not the base of thymine. rna consists of uracil, not thymine.

lastly your fourth option being correct! this answer is correct, because both sugar ribose, and the base uracil are in rna! ~

answer is d. sugar ribose and the base uracil.

Elephants in the savanna regions of africa dig holes in dried up river beds to reach water lying just below the surface. these holes provide drinking water for other animals as well. so, without the elephants, many animals might otherwise die from lack of water during the dry season. the location in which the elephants live is an example of a/n and the role they play in creating water holes is an example of a a) ecosystem; habitat b) community; niche c) habitat; niche d) niche; habitat

Which statements best describe the differences or similarities between a comparative investigation and an experimental investigation? check all that apply. experimental investigations are best for showing cause-and-effect relationships, while comparative investigations do not necessarily show this type of relationship. comparative investigations are often impractical and unrealistic, while experimental investigations are the most practical and realistic kinds of investigations. comparative investigations allow for the use of a wide range of variables but do not have a control group, while experimental investigations involve variables that can be controlled. both experimental investigations and comparative investigations are designed to answer scientific questions. both experimental investigations and comparative investigations focus on making observations rather than collecting new data.
