Answer:

Sensation.

Explanation:

The sensory receptors are responsible for the detection of stimuli. The bottom up and top down control are the two important processing that helps in the introductions of sensory information in the body.

Sensation is the process by which the organisms detect the internal as well as external stimuli. The three main process that are involved in sensation are detection of stimuli from the environment, the change of stimuli in electrical signal and then received by the brain for further processing.

Thus, the correct answer is sensation.

My name is Ann [436]

Answer:

external

Explanation:

<em>Through the process of photosynthesis, plants use the sun's energy to make sugars to function. External means from an outside force, while internal means from within. Since the sun isn't inside a plant, they gather it from outside, thus it's external.</em>

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>
