Answer:
Explanation:
The two main functions of stomata are to allow for the uptake of carbon dioxide and to limit the loss of water due to evaporation. In many plants, stomata remain open during the day and closed at night. Stomata are open during the day because this is when photosynthesis typically occurs.
The primary function of the plasma membrane is to protect the cell from its surroundings. Composed of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules and regulates the movement of substances in and out of cells.
Answer:
Interrupted mating experiments can determine gene order on the Hfr bacterial chromosome.
Explanation:
Interrupted mating is a technique used in experiments involving microbiology. This experiment was created by geneticists François Jacob and Elie Wollman, in the late 1950s. This technique allows the mapping of the genes of the bacteria involved in the place where the conjugation was interrupted, within monitored and controlled time intervals. In this way, the technique allows showing the transfer mechanisms and the gene transfer itself.
In relation to the question above, we can say that the interrupted mating experiments can determine the order of the genes on the bacterial chromosome Hfr.
