Answer:

If the rock samples obtained are in the order A-B-C-D from top to the bottom then fossil found in layer B has more similarity to fossil in layer A than layer D.

Explanation:

To estimate the age of fossil we try to determine the age of rock from where the fossil was obtained. The deeper the rock layer, older the fossil would be. Here in the question the most deepest layer of rock is D which means the fossil remains obtained here would be the oldest and can be considered as the ancestor of other the fossils obtained in the layers above it.

The top most layer is A, which is the most recent layer and would contain fossil remains of most recently fossilized animal. Fossils obtained from adjacent layers are expected to have more similarities than the ones obtained from distant layers. Since rock layer B is more closer to A, it will have the fossils with more similarities to fossils in layer A than in layer D.

When a scientist uses radiometric dating to determine the age of a rock specimen, would he use a radioactive element with a shor
xenn [34]

Answer:

He will use a radioactive element with a long half life of greater than 1 billion years

Explanation:

Rocks are an aggregation of solid mass which is usually rich in minerals. The age of rocks is established using radiometric dating method.

According to Oxford Dictionary, radiometric dating is "a method of dating geological specimens by determining the relative proportions of particular radioactive isotopes present in a sample."

The age of rocks can only be ascertained using isotopes that have very long half lives because many of these rocks are very old (aged billions of years) hence their age can only be determined using elements that has a half life greater than 1 billion years.

Answer:

4 1/4

Explanation:

17/4 = 4/4 + 4/4 + 4/4 + 4/4 + 1/4

4 + 4 = 8

4 + 4 = 8

8+8=16 = 16/4

16/4 + the 1/4 remaining in the equation = 17/4

so 4/4 + 4/4 + 4/4 + 4/4 = 4

4 + 1/4 = 4 1/4

sorry if you couldnt follow along. I am not good at explaining things but the answer is 4 1/4

makvit [3.9K]

Answer:

Bottleneck effect

Explanation:

The Bottleneck effect is when species go through an event that reduces its population. The ones that survive have reduced genetic diversity compared to the original population since fewer individuals means there are fewer genotypes.
