Which of the following is a scientific statement?
skad [1K]

The correct answer is D. According to DNA comparisons, humans share a common ancestor with chimpanzees.

Explanation

A scientific statement is a statement made based on scientific evidence, that is, a scientific statement is the result of several tests focused on testing a hypothesis or proposal. These scientific statements can be developed in different areas of knowledge such as science, biology, physics, mathematics, geometry, among others. they are also predominant in the exact sciences because in the human sciences it is complicated to establish scientific statements because human behavior does not obey exact laws. According to this definition, option D. is the correct answer because it refers to DNA tests between humans and chimpanzees and therefore this is based on scientific evidence and tests.

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>
