Explanation of Solution
In the digestive system there are many organs. It starts from the mouth or the buccal cavity and ends at anus. All the organs have different functions. The lists of various organs involved in the digestive system are as follows:
- 1. Buccal cavity: It is the cavity of the mouth. Food is chewed and masticated and grinded by the teeth and its digestion starts with the action of a carbohydrate lytic enzyme called the ptyalin or the salivary amylase.
- 2. Esophagus: It is a long narrow tube from where the food passes to the stomach for further digestion.
- 3. Stomach: It is a pouch like structure where the digestion of food materials. The secretion of hydrochloric acid apart from some enzymes which helps in digestion of the food substances like the proteins, carbohydrates, fats and so on.
- 4. Small intestine: It is a long and highly convoluted tubular structure. In this part of digestive system where the absorption of vital nutrients and minerals takes place. It is also the last site where the digestion takes place.
- 5. Large intestine: It is also a tubular structure. Here only the final absorption of mainly water and the essential nutrients takes place. No digestion takes place in the large intestine.
- 6. Anus: It is that part of the digestive system from where the waste, unwanted fecal, and the undigested matter are excreted out of the body.

In a natural population of outbreeding plants, the variance of the total number
of seeds per plant is 16. From the natural population, 20 plants are taken into
the laboratory and developed into separate true-breeding lines by self-
fertilization-with selection for high, low, or medium number of seeds-for 10
generations. The average variance in the tenth generation in each of the 20 sets
is about equal and averages 5.8 across all the sets. Estimate the broad-sense
heritability for seed number in this population. (4 pts)

Assessing drug kinetics following multiple routes of administration provides greater insight than a single route of administration alone.

Using this data and set of graphs, determine:(calculate for each variable) (a) k, C0, V, and AUC* for the bolus iv data (b) k, ka, B1, and AUC* for the po data c) k, ka, B1, and AUC* for the ip data (d) relative bioavailability for po vs ip, Fpo/Fip (e)absolute ip bioavailability, Fip (f) absolute po bioavailability, Fpoarrow_forward3. A promising new drug is being evaluated in human trials. Based on preliminary human tests, this drug is most effective when plasma levels exceed 30 mg/L. Measurements from preliminary tests indicate the following human pharmacokinetic parameter values: t1/2,elim = 4.6hr, t1/2,abs = 0.34hr, VD = 0.29 L/kg, Foral = 72%. Based on these parameters, estimate the following if a 49 kg woman were to receive a 1000mg oral dose of this drug: (a) Estimate the plasma concentration of the drug at 1hr, 6 hr, and 20hr after taking the drug ( Concentration estimate) (b) Estimate the time for maximum plasma concentration (tmax). (c) Estimate the maximum plasma concentration (Cmax). (d) Estimate the time at which the plasma level first rises above 30 mg/L. (Note this is a trial and error problem where you must guess a time, plug it into the concentration equation, and determine if it is close to 30 mg/L.
