Answer:
False, the nucleus is not <em>inside</em> the chromosomes, but the chromosomes are inside the nucleus.
The atomic mass of an element is a result of the weighted average of the masses of its corresponding isotopes.
<span>We are given: </span>
<span>Sb-121: mass of 120.9038 amu, x abundance </span>
<span>Sb-123: mass of 122.9042 amu, 1-x abundance </span>
<span>To be able to calculate the atomic mass of antimony, we multiply the percent abundances of the isotopes by their respective atomic masses. Then, we add,</span>
<span>Atomic mass = (Atomic Mass of Sb-121) (% Abundance) + (Atomic Mass of Sb-123) (% Abundance )</span>
121.760 amu = (120.9038 amu)(x) + (122.9042 amu)(1 -x)
<span>Solving for x,</span>
<span>120.9038x + 122.9042 -122.9042x = 121.760</span>
<span>x = 0.57096 or 57.096% </span>
1-x = 1-0.57096 = 0.42904 or 42.90%
Answer:
D
Explanation:
BEcause you are testing which objects will stick. Your control variable will be the sweater. And the number of times you rub the object on the sweter will not make it stick. It will make it stick for a longer period.
Joules/ (Grams * Kelvin)
Kelvin = Celsius + 273.15
The answer would be C because I did the test and I got 1 question wrong and made an 90% .
