Chemical digestion involves breaking down the nutrients into smaller cells
Physical digestion is using physical movements such as chewing and swallowing
Answer:
The correct answer is - passive immunity - artificially acquired.
Explanation:
Passive immunity is the immunity that involves giving or acquiring antibodies from other sources instead of developing them on one's own. This type of immunity can be natural and artificial. Mother breastfeed the babies, is the natural passive immunity example as milk also contain antibodies required for immunity of babies.
Artificial passive immunity is the immunity that comes from injecting the antibodies created in different animals or persons which called antiserum or vaccines such as snake antivenom.
The chemical reactions in the cell would not happen as fast and would require more energy to catalyze the reaction between the two reactants.

Chemistry/ Example: Take breathing for example, when you breath you breath out carbon dioxide. The CO2 can't just leave like that and only 10% binds to hemoglobin. The rest turns into carbonic acid in your blood and its plasma. However, the acid is unstable, so it turns into bicarbonate and a dissociated proton (H). You have carbonic anhydrase that converts the two so you can breath out CO2; the carbonic acid separates into H2O and CO2. This process would take a LONG time without the enzyme-- CO2 build up, even minimal amounts it lethal.
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".
