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>

A scientist discovers a cell that has chloroplasts, cytoplasm, DNA, and a cell membrane. Which statement best describes how the
Zina [86]
<span>The correct answer is The cell is eukaryotic because it has chloroplasts. Prokaryotic cells don't have chloroplasts as they are only found in eukaryotic cells. The closest thing there is to chloroplasts are the cyanobacteria who function similarly and also photosynthesize but are in the end not chloroplasts themselves.</span>

Jlenok [28]

Answer:

Places and location.

Explanation:

In gymnosperms, the pollen and the megaspores are produced in separate places. Megaspores made in cones that develop into the female gametophytes that is present inside the ovules of gymnosperms, while pollen grains develop from cones that produce microspores. while on the other hand, In angiosperms, the pollen and the megaspores are produced in separate structures, but within the same place i.e. flower which has both male and female reproductive organs.
