It's mostly because of antibodies:

What is antibodies: Antibodies are specialised proteins that are produced in response to anything that your immune system might need to fight off, such as bacteria and viruses.

A type blood has anti-B antibody in the plasma

B type blood has anti-A antibody in the plasma

AB has neither A nor B antibody in the plasma

O has both A and B antibody in the plasma.

For example, if someone with Type O blood received blood from someone with Type B blood, the recipient’s immune system would identify the new blood cells as foreign and therefore destroy them.

The fibrous structure that functions to anchor the atrioventricular valves in a closed position is d. chordae tendineae.

The chordae tendineae are thin, fibrous cords that attach the atrioventricular valves (tricuspid and mitral valves) to the papillary muscles. When the ventricles contract, the papillary muscles also contract, which tightens the chordae tendineae and prevents the valves from prolapsing or being pushed back into the atria. This ensures that blood flows in the proper direction, from the atria to the ventricles.

The chordae tendineae play a crucial role in anchoring the atrioventricular valves in a closed position during ventricular contraction, ensuring proper blood flow and preventing valve prolapse.

Answer:

Explanation:

To find a 95% confidence interval for the population mean body temperature of healthy females, we can use the theory-based (t-distribution) approach since the sample size is relatively small (n = 67) and the population standard deviation is unknown.

Using the information provided, the mean body temperature for the sample is 98.85 °F, and the standard deviation is 0.852 °F. The formula for the confidence interval is:

Confidence Interval = sample mean ± (t-value * standard error)

First, we need to determine the t-value for a 95% confidence level with (n-1) degrees of freedom. In this case, the degrees of freedom are 67 - 1 = 66. Using a t-table or statistical software, the t-value for a 95% confidence level and 66 degrees of freedom is approximately 1.997.

Next, we calculate the standard error, which is the standard deviation divided by the square root of the sample size:

Standard Error = standard deviation / √sample size

= 0.852 / √67

≈ 0.104

Now we can calculate the confidence interval:

Confidence Interval = 98.85 ± (1.997 * 0.104)

Simplifying the calculation:

Confidence Interval ≈ 98.85 ± 0.208

Rounding to two decimal places, the 95% confidence interval for the population mean body temperature is approximately (98.64, 99.06) °F.

To determine whether 98.6 °F is a plausible value for the population average body temperature, we need to check if it falls within the confidence interval. In this case, since 98.6 °F is within the confidence interval of (98.64, 99.06) °F, it is a plausible value for the population average body temperature. This means that based on the sample data, there is no strong evidence to suggest that the average body temperature significantly differs from 98.6 °F.

In terms of using the theory-based (t-distribution) approach to find the confidence interval, it is valid in this study because the sample size is small and the population standard deviation is unknown. The t-distribution accounts for the uncertainty introduced by using the sample standard deviation to estimate the population standard deviation.

Functional genomic approaches are favored over biochemical approaches to determine the function of a gene for all these reasons, except "biochemical approaches are more expensive." The correct option is B.

Functional genomic approaches are favored over biochemical approaches to determine the function of a gene for several reasons.

One of the main advantages of functional genomic approaches is that they can bypass the need to isolate individual proteins, which can be time-consuming and technically challenging.

Instead, these approaches use computational methods to identify gene function from DNA sequence alone, allowing for more efficient and high-throughput analysis of gene function.

Another advantage of functional genomic approaches is their accuracy.

By examining the effects of gene expression on cellular processes, these approaches can provide a more comprehensive understanding of gene function than biochemical approaches that focus on the properties of individual proteins.

However, one of the reasons that functional genomic approaches are preferred over biochemical approaches is not that they are more cost-effective.

In fact, functional genomic approaches can be more expensive than biochemical approaches, particularly if they involve the use of high-throughput sequencing technologies or the development of new computational methods.

Nonetheless, the benefits of functional genomic approaches in terms of speed, accuracy, and comprehensiveness often outweigh the increased cost. Therefore, the correct answer is B.
