Answer:

B. Find the relative age of one rock layer at the given location

Explanation:

Relative age is determined by the chronological order of a sequence of events. Relative dating is based on the concept of relative age and various geological principles, such as the principle of initial or original horizontality, the principle of overlap and the principle of paleontological identity. Relative dating is therefore based on the presence of fossils in rocks and / or the relative position of geological formations.

Based on this, we can say that if a geologist wanted to determine the age of the rock layers in a given location using the relative age, he should find the relative age of a rock layer, using relative dating in the indicated location

A geologist is studying two different rhyolite flows to determine if they were erupted at the same time.
ss7ja [257]
Q1. The answer is 1.

It can be calculated using the equation:

 (1/2)ⁿ = x

x - decimal amount remaining, 

n - a number of half-lives.


x = 50% = 50/100 = 0.5

n = ?

(1/2)ⁿ = 0.5

log((1/2)ⁿ) = log(0.5)

n * log(1/2) = log(0.5)

n * log(0.5) = log(0.5)

n = log(0.5)/log(0.5)

n = 1


Q10. The answer is 2.


It can be calculated using the equation:

 (1/2)ⁿ = x

x - decimal amount remaining, 

n - a number of half-lives.


Rhyolite #2 has 25% of the parent H remaining:

x = 25% = 25/100 = 0.25

n = ?

(1/2)ⁿ = 0.25

log((1/2)ⁿ) = log(0.25)

n * log(1/2) = log(0.25)

n * log(0.5) = log(0.25)

n = log(0.25)/log(0.5)

n = -0.602 / - 0.301

n = 2



Q3. The answer is 100 million years.


A number of half-lives (n) is a quotient of total time elapsed (t) and length of half-life (H):

n = t/H

n = 1

t = ?

H = 100 000 000 years


n = t/H

t = n * H

t = 1 * 100 000 000 years

t = 100 000 000 years<span>

HELP!!!! Restriction maps illustrate the lengths of DNA fragments between restriction sites. Which of the following information
balandron [24]
The wording of this is confusing. I think it’s A and B and I’m hesitant say that it’s also C but only if you know the mutation and the gene.

Also for A you would only know a partial sequence of the gene.

Answer:

Viral replication involves six steps: attachment, penetration, uncoating, replication, assembly, and release. During attachment and penetration, the virus attaches itself to a host cell and injects its genetic material into it.
