What holds the two strands of DNA molecules to each other. Hydrogen Bonds
Answer:
1) By 11:30pm
2) Shortly before midnight (few minutes to 12:00am)
Explanation:
Since the strain of bacteria takes 1 minute to divide (double its population), and by midnight (12:00am) the entire bottle becomes full, then:
I) Subtract Initial division time from Final division time i.e 12:00 - 11:00 = 1 hour
II) Split 1 hour into two (60minutes makes 1 hour)
I hour/2 = 30 minutes
Definitely, the bottle will be half filled by 11:30pm
2) Once half filled, the rapidly dividing cells reach for the top of the bottle as midnight approaches. By 11:50pm upwards, bottle space must have been running out
Answer:
A codon is found on the coding strand of double-stranded DNA and in the (single-stranded) mRNA. The anticodon is found on the tRNA and is the part that base-pairs with the codon (on the mRNA) in order to bring the appropriate amino acid to the ribosome to be added to the growing peptide chain.

Answer:
The correct answer is - palisade cells that are type leaf cells.
Explanation:
The outer layer of cells does not contain chloroplast that is a protective layer called the epidermis. The palisade layer is immediate to the top layer of the leaf that contains most of the chloroplast in comparison to the other parts of the roots or leaf cells.
Chloroplast contains chlorophyll that collects sunlight in order to initiate photosynthesis. There are different types of chlorophyll types present in the cell of the plant.
Thus, the correct answer is - palisade cells that are type leaf cells.
