Answer:
It is copied.
Explanation:
Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules.
p = m / V (Density = Mass / Volume)
p = m / (w * l * h) (Density = Mass / [Width * length * height]) (V = w * l * h)
p = 120 / (5 * 4 * 3) (Mass = 120g [Given] w=5 l=4 h=3 [Given])
p = 120 / 60
p = 2 g/cm^3
Answer is B (2)
C. telophase and cytokinesis
Explanation:
I'm not sure how I explain this tho
Answer is b. Burning fossil fuels causes a decrease in the pH of ocean water making it more acidic.
Burning of fossil fuels release carbon dioxide and other harmful gases in the atmosphere. Carbon dioxide gets dissolves in the ocean to form carbonic acid. Due to formation carbonic acid, the pH of ocean water changes slightly. The average pH of ocean water was 8.2 slightly basic. Now it 8.1, it means there is 25 % increase in acidity of ocean water.
Would not be to distinguish between labeled DNA and amino acids.
