The fraction of the original amount remaining is closest to 1/128
<h3>Determination of the number of half-lives</h3>
- Half-life (t½) = 4 days
- Time (t) = 4 weeks = 4 × 7 = 28 days
- Number of half-lives (n) =?
n = t / t½
n = 28 / 4
n = 7
<h3>How to determine the amount remaining </h3>
- Original amount (N₀) = 100 g
- Number of half-lives (n) = 7
- Amount remaining (N)=?
N = N₀ / 2ⁿ
N = 100 / 2⁷
N = 0.78125 g
<h3>How to determine the fraction remaining </h3>
- Original amount (N₀) = 100 g
- Amount remaining (N)= 0.78125 g
Fraction remaining = N / N₀
Fraction remaining = 0.78125 / 100
Fraction remaining = 1/128

Answer:
genes are small sections of DNA. These genes contain instructions that tell your cells to make molecules called proteins. And the protein do things to your body to keep you healthy. Genes determine traits as well.
Data:
V1 (initial volume) = 233 mL
P1 (initial pressure) = 622 kPa
V2 (final volume) = ? (mL)
P2 (final pressure) = 988 kPa
Formula:
P1 * V1 = P2 * V2
Solving:
P1 * V1 = P2 * V2
622 * 233 = 988 * V2
114926 = 988 V2
988 V2 = 114926
Answer: 1. h oxidized, 2. g reduced, 3. e glucose, 4. c pyruvate, 5. b NAD+, 6. a NADH.
Explanation:
Glycolysis is also known as Embden-Meyerhof pathway, and in this process one mole of glucose is oxidised into two moles of pyruvate in a series of enzyme-catalyzed reaction and do not involve molecular oxygen i.e. oxygen indepenedent process. This process is studied in two phases preparatory (energy-investment) and pay-off phase(energy generation).
Net reaction: Glucose + 2NAD+ HPO4-2 = 2 Pyruvate + 2NADH + 2ATP + 2H2O.
