Answer:
b. The daughter cells have the same number of chromosomes and the same amount of DNA.
Explanation:
Mitosis is the cell division that maintains the DNA amount and chromosome number in daughter cells. This is due to the fact that each mitosis is preceded by one round of DNA replication in S phase.
For example, if the parent cell had 2n DNA in 46 chromosomes, the daughter cells at the end of mitosis and cytokinesis would also have 2n DNA in 46 chromosomes.
No, even after several days of incubation, you shouldn't detect any symptoms of microbial growth in a sterile medium.
<h3>What is the microbial growth in the sterile medium?</h3>
The deliberate introduction of germs into a sterile growing medium is known as immunization. When there are no living creatures present, a substance is sterile; undesirable bacteria are said to be contaminated. The use of aseptic procedures helps keep growing media from being contaminated. Reduce the amount of time that cultures and growth media are exposed to the outside world. Clean the work area both before and after each use. Avoid breathing or touching the stock cultures or sterile culture media. Before used, loops, needles, pipes, and other items should be sanitized. The tube caps should be held in your hand while inoculating and not placed on the table while using tubes.
