(Multiple questions) Which is not an assumption that is needed if radiometric dating is to be an accurate measure of the age of an object?
A.) Half-lives can change over time.
B.) The speed of light is a constant.
C.) The amount of material being measured is constant.
D.) All of these.


Another method of dating that supports radiometric dating is
A.) tree rings
B.) ice cores
C.) coral growth
D.) all of these
30 points (i think) if you get them both :DD

Answers

Answer: Question #1: A

Question #2: A

Explanation: Question #1: The constant speed of light has nothing to do with radiometric dating nor the continual material being measured.

Question 2: Tree rings may be another dating method because trees develop more rings as the radioactive material decays over time.

Question 1 and question 2 are both A

DNA replication begins when the double helix untwists and breaks in half between the nitrogen bases. What are the next two steps in the process of DNA replication?

Answers

Answer:

Step 1: Before DNA can be replicated, the double stranded molecule must be “unzipped” into two single strands. ... Step 2: Primer Binding. The leading strand is the simplest to replicate. ... Step 3: Elongation. ... Step 4: Termination

The DNA gets unzipped during DNA replication after the double helix unwinds. Each original DNA strand acts as a template for the new strands when the strands are split in two. The bases on either half of DNA are then paired with the nitrogen bases that have sugar and phosphate. In order to adhere to the principle of base pairing and guarantee that the base sequence is maintained, the molecules present in the new strand must be complementary to those found in the original strand. DNA replication ends with the formation of two identical strands.

The ocean product I have researched in the "investigation: ocean products" module is petroleum. I have learnt that it can be found in layers of sediments as seen on ocean floor.

Does petroleum come from the ocean?

Fossil fuels such as coal, natural gas, and that of petroleum developed under comparable conditions. Petroleum can now be discovered in huge subsurface reservoirs that were once ancient seas.

They are seen under the surface of the land or the water, there are petroleum reservoirs. Utilizing enormous drilling equipment, their crude oil is extracted.

Note that  Over the course of millions of years, when the bones of dead animals and plants settle to the ocean floor, gas and oil are formed in the sea. They are buried and crushed into layers of sediment several kilometers deep on the ocean floor when combined with particles discharged from the land.
