Computational methods can be applied at the early stages of the drug design process. It is use current technology to provide valuable insights into the understanding of chemical system in a virtual manner. By integrating the TWO (2) computational methods; molecular docking and molecular dynamics simulation, explain how these TWO (2) methods can be integrated in computational drug design.

1. Which of the following biomes is likely to have the longest food chains?
Tundra |
||
Boreal forest/Taiga |
||
Temperate deciduous forest |
||
Open ocean |
||
Desert |
2. A key difference between the carbon, nitrogen, and phosphorus cycles is
carbon dioxide dissolves more readily in oceans than nitrogen |
||
phosphorus enters the biosphere primarily through soil rather than air and is less renewable than carbon dioxide or nitrogen |
||
most nitrogen in the atmosphere is in a readily usable form whereas carbon in the air is hard to use |
||
carbon is more abundant in the air than nitrogen and phosphorus combined |
||
the carbon cycle is strongly affected by human activity while the nitrogen and phosphorus cycles are unaltered |
3.

primary producer |
||
primary consumer |
||
secondary consumer |
||
tertiary consumer |
||
secondary detritivores |
4.
The biome contributing most to earth's total net primary productivity is
tropical rainforest |
||
boreal forest |
||
temperate deciduous forest |

1, Which of the following is FALSE regarding a woman's choices during pregnancy and lactation, to help ensure the best outcome for the fetus/infant:
Group of answer choices
a pregnant woman needs as many kcalories as possible to ensure proper growth of her baby, and does not need to worry about overeating during pregnancy
a woman should abstain from alcohol during pregnancy
a mother's nutritional status during pregnancy, and her choice/ability to breastfeed for as long as possible, may affect a child's health even into adulthood
a woman should pay attention to folate intake before she becomes pregnant
a woman should check with her physician before consuming any drugs or supplements, even if they are over-the-counter
breastfeeding for at least the first 6 months will likely reap many benefits for both mother and baby
a woman should continue low impact, regular exercise during pregancy
2, It is typically recommended that introduction of solid foods to infants take place
Group of answer choices
between 4 to 6 months
as soon as the infant displays interest
between 1 and 2 years of age
3, Which of the following is true of food allergies
Group of answer choices
about 25% of young children (under four years of age) are diagnosed with food allergies
food allergies tend to increase with age
true food allergies are always associated with symptoms
food allergies are considered the same as food intolerance
true food allergies elicit an antibody response

(Q001) Glucose-6-phosphate dehydrogenase deficiency (G6PD
deficiency) is an inherited disorder where either the body has less
of the G6PD enzyme than normal or the available G6PD is not
functioning correctly. This deficiency affects red blood cell
function and may result in anemia (the destruction of red blood
cells) when people with the condition have infections, are taking
certain medications, or eat certain foods. People with G6PD
deficiency may have some protection from malaria because their
abnormal red blood cells interfere with the reproduction of the
malaria parasite in their bodies.
Consider the prevalence of G6PD deficiency estimated by the World
Health Organization (WHO) as shown in the map on p. 247 of your lab
manual. Compare the distribution of G6PD deficiency with the
distributions of the sickle-cell trait and malaria shown in Figure
8.9 on p. 238 of your lab manual. What similarities between these
distributions do you notice? What differences do you notice?
(Q002) Why might these similarities and differences exist? Be sure to consider the evolutionary context (including the natural environment, cultural practices, and interbreeding).
