Answer:
65536 cells
Explanation:
starting from 1 cell at zero minutes there will be 1 (2^0) cell; 2^0 = 1
after 15 minutes there will be 2 (2^1) cells
after another 15 minutes ( 30 min) there will be 4 ( 2²) cells
after another 15 minutes ( 45 min) there will be 8 (2³) cells
after n number of 15 minutes there will be (2^n) cells
calculate number of 15 minutes in 4 hours
4 hours = 4 × 60 minutes
number ( n) of 15 minutes in 4 hours = (4 × 60 minutes) / 15 minute = 16
using the formula above and substitute 16 for n in the formula
Number of cells = 2 ^n = 2^16 = 65536 cells

Answer: A short incubation time runs the risk of a false negative on the VP test, since not enough time may have elapsed to produce an adequate amount of acetoin to give a positive result. The pH change associated with mixed acid fermentation occurs fairly quickly and is less likely to be affected by shorter incubation.
b) The VP test would benefit most from a longer incubation time because it takes a while for the 2,3-butanodiol to be produced.
Explanation:
Answer:
The xylem is a vascular tissue responsible for the transportation of water from the root to other parts of the plant. While the phloem is responsible for the transportation of soluble organic nutrients gotten from photosynthesis, to other parts of the plant.
Explanation:
The xylem is a hollow tube made up of dead empty cells that continues throughout the whole length of the trunk of a plant. The cohesive (i.e water attracts water) and adhesive (i.e water attracts xylem) nature of water makes it possible for water to move from the root which is the major source of water transported, up to the topmost leaf of the plant in a process called capillarity. An upward pull, which keeps the upstream of water continuous is generated during transpiration (i.e the loss of water from the plant).
The phloem, which is also hollow in nature, transports glucose from photosynthetic regions of the plant, majorly the leaf, to other parts of the plant. This process is called translocation.
