Can you please post option too
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>

Answer: The two species were Rhesus monkey and Human <span>
Hemoglobin protein is the iron containing protein found in
the red blood cells which function by transporting oxygen through the blood
stream from from the lungs to the tissues and it is important for survival. However,
the two species that
have similar amino acids in the hemoglobin protein were Rhesus monkey and Human
because they were not far from others.</span>
<span>A low level of TSH is indicative of hyperthyroidism. This is a medical condition in which the thyroid gland secrets or produces an excess of hormones resulting in an imbalance. This condition if left untreated can cause many undesirable effects such as muscle weakness, low quality of sleep etc.</span>
