Summary Introduction

Introduction: Animals have a number of characteristics that distinguish them from other organisms. The characteristics include multicellularity, the presence of an extracellular matrix, heterotrophic feeding, and possession of nervous and muscle tissues.

Expert Solution & Answer

Answer to Problem 1TY

Correct answer:

Possession of cell walls is not a distinguishing characteristic of animals. Hence, the correct answer is option b.

Explanation of Solution

Reason for correct answer:

Animals can be defined as multicellular heterotrophs with cells that lack cell walls, the capacity to move at some point in their life cycle, and the ability to reproduce sexually.

Option b. is given as “possession of cell walls”.

Animal cells lack a cell wall and are quite flexible. The cells of plants, fungi, bacteria, archaea, and most protists possess a rigid cell wall. Hence, the correct answer is option b.

Reasons for incorrect answer:

Option a. is given as, “the capacity to move at some point in the life cycle”.

Most animals have a muscle system, which allows them to move in their environment. Hence, option a. is incorrect.

Option c. is given as, “multicellularity”.

Animals are multicellular in nature, for example sponges (a simple type of animal). Hence, option c. is incorrect.

Option d. is given as, “heterotrophy”.

Animals obtain their food by eating other organisms. Plants and algae are grouped as autotrophs since they produce their own food. Hence, option d. is incorrect.

Option e. is given as, “All of the above are characteristics of animals”.

Animal cells do not possess a cell wall. Therefore, presence of cell wall in animal cells is not considered as a distinguishing characteristic of animals. Hence, option e. is incorrect.

Hence, the options a., c., d., and e. are incorrect.

Conclusion

Thus, possession of cell walls is not a distinguishing characteristic of animals.

1. In vivo testing provides valuable insight into a drug’s kinetics. Assessing drug kinetics following multiple different routes of administration provides greater insight than just a single route of administration alone. The following data was collected in 250 g rats following bolus iv, oral (po), and intraperitoneal (ip) administration.Using this data and set of graphs, determine: (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 po bioavailability, (f)Fpo absolute ip bioavailability, Fip MAKE SURE ANSWERS HAVE UNITS if appropriate. SHOW ALL WORK, including equation used, variables used and each step to your solution.

2. Drug quantification from plasma is commonly performed by using techniques such as HPLC or LC/MS. However, these methods do have limitations, and investigators may choose to use a radiolabeled analog of a drug instead. Radioligands are molecules that contain radioactive isotopes, commonly 3H or 14C. This technique allows investigators to quantify drug concentration from radiation measurements. The following measurements were made in 250 g rats following oral administration of 18.2 µCi of a 14C-labeled drug of interest: Time (min) Plasma Radiation Levels (µCi/L) 0 0.0 2 9.7 4 19.2 7 25.3 9 37.8 12 39.6 14 45.8 17 48.8 20 52.0 25 56.4 30 59.2 35 60.1 40 61.1 45 62.1 50 62.8 60 63.1 70 62.1 80 60.1 90 57.3 100 55.5 110 53.7 120 52.2 150 48.0 180 45.0 240 39.0 Note that a µCi is a measure of the amount of radioactivity and hence is a measure of the amount of drug present. Given that the oral bioavailability of this drug is known to be essentially 100%, estimate the following from this…
