15% of a batch of mixed-color gumball are green. Out of a random sample of 20 gumball, what is the probability of getting two green balls?
Select the correct statement concerning "boiling point" and"normal boiling point". The "normal boiling point" temperature of water can be greater than 100 °C. The "boiling point" temperature of water is 100 °C. The boiling point of a substance is the temperature at which the vapour pressure of the liquid equals the atmospheric pressure. None of the above is correct. The normal boiling point of a substance is the temperature at which the vapour pressure of the liquid equals the atmospheric pressure.
DNA replication involves multiple steps that require different enzymes. Which process does primase catalyze in DNA replication? synthesis of a short RNA sequence that initiates DNA synthesis replaces RNA primer with DNA bond formation that joins nicked DNA strands breaking of hydrogen bonds and unzipping of double-stranded DNA
