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.
Answer: No.
Explanation:
Studying about diseases, their effect, cause and the prevention of diseases is known as Epidemiology, and the scientists that studies Epidermiology and take it as a professsion are called Epidermiologists.
From the question; assuming the epidemiologist who finds a correlation between the use of tanning beds and melanoma (an aggressive form of skin cancer) in college-age women, the Epidermiologist can NOT conclude that tanning beds cause skin cancer BECAUSE the fact that the the use of tanning beds CORRELATE with melanoma (an aggressive form of skin cancer) in college-age women does not PROOF THAT tanning beds cause skin cancer.
===>That is, the fact that something correlate with another thing does not make it the cause.
Assuming her weight loss is going to happen through nutrition alone. This question can be answered if we make apparent a few points. One pound is equal to 3500kcals. Jackie needs to lose 15lbs in 3 months. Therefore, she really needs to lose 52,500kcals (15lbs x3500kcals). In 3 months this equates to a caloric deficit of approx 584kcals/day (52,500kcals divided by 90days). So in order to reach her target goals she’s needs to be in a caloric deficit of 584kcals a day for 3 months from her current caloric intake that permits the maintenance of her body weight.
Your answer would be proteins.
