oceanic acidification is occurring, which results in shelled creatures, clams, lobster, to have weaker shells as a defense. the shells break easily and are too weak to protect the organisms inside, unable to properly calcify their shells leaves them vulnerable to preditors...
Correct question:
if a nondisjunction occurs at anaphase I of the first meiotic division, what will the proportion of abnormal gametes (for the chromosomes involved in the nondisjunction)?
Answer:
100%
Explanation:
Nondisjunction at meiosis-I means that two homologous chromosomes of at least one homologous pair fail to separate from each other during anaphase-I. This would result in the formation of one cell with one extra chromosome and the other with one less chromosome by the end of meiosis-I. Meiosis-II in these two cells would maintain this chromosome number in the daughter cells. Therefore, out of the total four gametes formed by the end of the meiosis, two would have one extra chromosome and would be denoted as "n+1". The rest of the two gametes would have one less chromosome and would be denoted as "n-1".
The biological factors other than lateral and ventromedial hypothalamus that influence hunger are; the blood sugar level-glucose, Hormones-Insulin must be present to extract glucose from blood and stimulates the storage of food, and set point. Additionally, we have environmental factors that influence hunger, these includes; taste, learned preferences, habits, stress and external food cues.
