Answer: The correct answer is B; E. Coli.
Explanation:
E. Coli can be prevented by cooking meat thoroughly. This bacteria can be killed if the internal temperature reaches 160 degrees fahrenheit. If a person is cooking leafy veggies, it is hard to get a correct temp, however, if the leaves are wilted, the bacteria should be gone. This bacteria can also be found in some water sources such as well water.
To help prevent the spread of this bacteria, never eat uncooked meat,wash your hands with soap and hot water, and clean surfaces after having raw meat on counters, etc.
Nondisjunction is defined as the failure of the chromosomes to seperate during cell division. An animal with a haploid number of 6 (diploid number of 12) undergoes meiosis, and at the meiosis II (cells are already haploid from the meiosis I), nondisjunction occurs. The mature ovum will contain 6+1 chromosomes (n+1) because there is an extra chromosome from the nondisjunction. The second polar body will contain 5 chromosomes (normal would be 6) because the second polar body did not receive that extra chromosome due to nondisjunction. In the event of fertilization of the abnormal ovum with a normal sperm, the zygote will be a diploid (12 chromosomes) normally but since the ovum as an extra chromosome from the nondisjunction then the zygote will have an extra chromosome (13 chromosomes). One pair of chromosomes has an extra single chromosome and this is called a trisomy.
