Answer:

At the bottom of the sequence

Explanation:

According to the "principle of superposition of strata", the oldest rocks are formed at the bottom of sedimentary rock sequences.

The oldest rock layer would contain the the oldest fossil. Weathering, erosion, transportation and deposition would bring all sediments which includes rock materials and remains of living organisms to the basin where they would be lithified to form sedimentary rocks. This makes the oldest fossil to be at the bottom of the sequence. As time progresses, the fossil sequence would continue to accumulate and young upwards as the strata becomes relatively younger. Also, we know that fossils succeed one another in a definite manner.

This why relative dating of rocks can be possible.

Answer:

Switching to sustainable energy sources such as solar power, hydroelectric power and wind power can reduce the amount of fossil fuels being used up. Fossil fuels are natural resources from the environment, but when burned the waste product of it is released into the environment and can potentialy affect other natural resources. Switching to a renewable energy source can help conserve natural resources. Renewable energy sources can be used to harness the energy we need without producing harmful products that affect the environment and it's resources.

Use the following template strand of DNA and the coding table to determine the correct amino sequence and write this sequence be

REY [17]

DNA and RNA have the main difference in the presence of deoxyribose sugar in DNA and ribose sugar in RNA. One more is the presence of thymine in DNA while the presence of uracil in RNA.

<h3>What is the codon?</h3>

Codon is actually a three-letter code which is a sequence of three consecutive nucleotides in a DNA or RNA molecule which generally codes for a specific amino acid.

The DNA sequence given here is:

T A T A T C T A C G G T C C G G C A T C G A T T T C G

So the RNA sequence for this will be:

A U A U A G A U G C C A G G C C G U A G C U A A A G C.

So according to the table, the amino-acid sequence will be:

Isoleucine STOP Methionine Proline Glycine Arginine Serine STOP Serine.

Generally stop codon is responsible for the termination of protein synthesis.

Thus, this was the amino acid sequence for mRNA according to the given DNA sequence.

Considering the experimental design, which claim is best supported using the data?

VLD [36.1K]

Answer:

C low competition for glucose

Explanation:

From the given answer choices and information,

It cannot be A since there is no visual disease or any indication of disease in the experiment

Cannot be B, since space would not be an issue since it clearly hit 111 on day 3

and cannot be D since there is no indication of a change in temperature.

However, we know Petri Dishes have nutrients to stimulate cell growth, and those resources are not unlimited therefore we can only attest that a large portion of the nutrients have been consumed and starved some of the cells thus causing a population decrease
