The optimum cost-time schedule for the project is C-F-G-H-I with a total project cost of $730.

To compute the total direct cost for each project duration, we multiply the crash cost (slope) by the difference between the normal time and the project duration. The direct cost represents the cost incurred by reducing the project duration.

By calculating the direct cost for each activity, we can determine the total direct cost for each project duration by summing up the direct costs of all activities.

Next, we add the indirect costs for each project duration, which are given as $90 (15 time units), $70 (14), $50 (13), $40 (12), and $30 (11).

To calculate the total project cost for each duration, we add the total direct cost and the corresponding indirect cost.

By comparing the total project costs for each duration, we find that the optimum cost-time schedule for the project is C-F-G-H-I. This schedule has the lowest total project cost of $730.

The arrows in the chart indicate the sequence of activities in the optimum cost-time schedule. The numbers indicate the project duration for each activity in that schedule.

In summary, the optimum cost-time schedule for the project is C-F-G-H-I, with a total project cost of $730. This schedule minimizes the total cost while completing the project in the shortest possible duration.

Nine amino acids are needed to travel through the thickness of the membrane.

Alpha-axial helix's distance between amino acids is 1.5. A

The number of gaps between the 22 amino acids in the helix is equal to (22-1) = 21.

Therefore, the helix's length is (21 X 1.5) = 31.5.

One alpha helix is sufficient to span the membrane's breadth, hence the formula is: span of the helix = thickness of the membrane = 31.5 A

The thickness of the membrane is determined by the formula above to be 31.5 AA.

In the beta-strand, there is 3.5 AA between each amino acid.

Therefore, (31.5/3.5) = 9 amino acids are needed.

If an eukaryotic cell normally contains 24 chromosomes, it would contain 24 chromosomes in the telophase stage of the cell division.

Cell division is a process by which a cell divides into two cells. Cell division can either occur via mitosis or meiosis.

Mitosis is the division of a cell nucleus in which the genome is copied and separated into two identical halves. It is normally followed by cell division.

Telophase stage is the last stage of mitosis during which the daughter chromosomes move towards opposite ends of the nuclear spindle.

This means 24 chromosomes will be present in the telophase stage of an eukaryotic cell with 24 chromosomes.

Genetic drift is a random fluctuation in allele frequencies within a population.

It can occur due to chance events such as natural disasters or random mating. In the case of the caucasian and aborigine populations, genetic drift could explain differences in genotype frequencies due to their different population sizes and histories.

The caucasian population is larger and has experienced more migration and interbreeding, leading to a more diverse gene pool.

The aborigine population, on the other hand, has a smaller population size and has experienced more isolation, which increases the chances of genetic drift occurring. Over time, this could lead to differences in genotype frequencies between the two populations.

The SDS-PAGE gel would show bands corresponding to the digested protein fragments with masses of 666 Da, 721 Da, 759 Da, 844 Da, 912 Da, 1028 Da, and 1486 Da. A standard ladder should be included for reference.

SDS-PAGE (Sodium Dodecyl Sulfate-Polyacrylamide Gel Electrophoresis) is a common technique used to separate proteins based on their molecular weight. In this case, the 6.4 KD (kilodalton) protein has been digested with trypsin, an enzyme that cleaves proteins at specific sites. The resulting fragments have different masses, which can be visualized on an SDS-PAGE gel.

The gel would consist of a polyacrylamide matrix through which an electric field is applied. The negatively charged SDS molecules bind to the proteins, causing them to unfold and acquire a negative charge proportional to their size. As a result, the proteins migrate towards the positive electrode during electrophoresis, with smaller proteins moving faster and migrating farther through the gel.

By running the digested protein fragments alongside a protein standard ladder, which contains proteins of known molecular weights, we can estimate the size of the fragments based on their migration distance. Each fragment would appear as a distinct band on the gel, and the position of the band relative to the ladder can be used to determine its molecular weight.

In this case, the gel would show bands corresponding to the fragments with masses of 666 Da, 721 Da, 759 Da, 844 Da, 912 Da, 1028 Da, and 1486 Da. The ladder bands would serve as reference points, allowing us to assign the appropriate mass to each fragment band.

Exposing cells to colchicine during meiosis II would most likely result in the production of cells with an abnormal number of chromosomes, also known as aneuploidy.

This is because colchicine prevents the separation of chromosomes during cell division, leading to the formation of cells with more than the normal number of chromosomes. Additionally, if the organism has two sets of homologous chromosomes that are not identical, the colchicine would cause a random assortment of chromosomes, resulting in the formation of cells with various abnormal chromosome numbers. Meiosis is a type of cell division that occurs in organisms that sexually reproduce. The process of meiosis reduces the number of chromosomes in the parent cell by half, creating four genetically diverse daughter cells, called haploid cells.

Blood pressure refers to the force exerted by circulating blood on the walls of blood vessels. The correct answers are:

(a) Approximately 0.1867 or 18.67% of women have blood pressures lower than 72.

(b) Approximately 0.0968 or 9.68% of women have blood pressures lower than 68.

(a) To find the proportion of women with blood pressures lower than 72, we need to calculate the area under the normal distribution curve to the left of 72. Using the mean (80.5) and standard deviation (9.6), we can standardize the value of 72.

Z = (X - μ) / σ

Z = (72 - 80.5) / 9.6 = -0.89

Using a standard normal distribution table or a calculator, we can find the corresponding proportion, which is approximately 0.1867.

Therefore, approximately 0.1867 or 18.67% of women have blood pressures lower than 72.

(b) To find the proportion of women with blood pressures between 70 and 92, we need to calculate the area under the normal distribution curve between these two values.

First, we standardize the values:

Z1 = (70 - 80.5) / 9.6 = -1.10

Z2 = (92 - 80.5) / 9.6 = 1.20

Using the standard normal distribution table or a calculator, we can find the area to the left of Z2 and subtract the area to the left of Z1 to find the proportion between these two values. The proportion is approximately 0.7837.

Therefore, approximately 0.7837 or 78.37% of women have blood pressures between 70 and 92.

(c) To find the proportion of women with hypertension (diastolic blood pressure greater than 90), we need to calculate the area under the normal distribution curve to the right of 90.

Standardizing the value:

Z = (90 - 80.5) / 9.6 = 0.99

Using the standard normal distribution table or a calculator, we can find the area to the right of Z, which is approximately 0.1611.

Therefore, approximately 0.1611 or 16.11% of women have hypertension.

(d) To determine if it is unusual for a woman to have a blood pressure lower than 68, we can calculate the proportion of women with blood pressures lower than 68 using the same method as in part (a).

Z = (68 - 80.5) / 9.6 = -1.30

Using the standard normal distribution table or a calculator, we can find the corresponding proportion, which is approximately 0.0968.

Therefore, approximately 0.0968 or 9.68% of women have blood pressures lower than 68.
