Summary Introduction

To explain:

The reason that the first meiotic division considered to be the reduction division for chromosome number.

Introduction:

Meiosis is a process of cell division in which four haploid daughter cells are produced. It is also known as a reductional division because the daughter cells receive the reduced number of chromosomes. Meiosis is important for the reproduction because it produces haploid gametes. Meiosis occurs in two stages meiosis I and meiosis II.

Expert Solution & Answer
Check Mark

Explanation of Solution

The meiosis I produce daughter cells that contain half the number of duplicated chromosomes because it separates the “homologous chromosomes” to produce daughter cells that are haploid. So, the daughter cells receive one chromosome from each homologous pair.

This is due to the events that takes place in the anaphase I where sister chromatids are together even after the pull from the spindle fibers. Such meiotic divisions produce haploid gametes in humans.

Conclusion

The first meiotic division considered to be the reduction division for chromosome number because it separates the homologous chromosomes to produce haploid daughter cells.

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…
