Answer:

Pig

Explanation:

Pig valves are already used successfully in heart transplants. Human-to-human organ transplantation has only been around since the 1950s, and scientists have been working on animal-to-human transplants for almost that long. In the '60s, Keith Reemtsma experimented with transplanting chimpanzee kidneys into humans.

Answer:

Pig

Explanation:

This process is called Xenotransplantation. The animal organ, probably from a pig or baboon could be genetically altered with human genes to trick a patient's immune system into accepting it as a part of its own body. (Wikipedia)

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.

A corn plant grows slowly at the first of the season, but speeds up with the appearance of each new leaf. The interval between new leaves will shorten as the season advances under non-stressful circumstances. Thus, option A is correct.

For corn seedlings to germinate and emerge quickly after planting, sufficient soil moisture is essential. As long as there is enough water in the soil, relatively low evapotranspiration after seedling emergence enables plants to thrive with little stress.

Loamy sand to clay loam are only a few of the several types of soils where maize can be cultivated successfully.

However, soils with high levels of organic matter, high water retention, and a neutral pH are thought to be good for higher productivity.

Therefore, A limiting factor for a field planted with corn every year is most likely soil nutrients.

After wastes are removed, blood leaves the kidney by way of the renal vein. Here option D is the correct answer.

The urinary system is responsible for extracting waste and unwanted substances from the body, as well as regulating bodily fluids. Blood is transported out of the kidney by the renal vein after the waste has been eliminated.

A blood vessel that carries blood from the kidneys to the inferior vena cava (the vein that carries deoxygenated blood from the lower body to the heart) is known as the renal vein.

Blood is transported into the kidneys via the renal artery and filtered, with waste and excess fluids being expelled via the ureter to the bladder. Urine leaves the body via the urinary meatus after being kept in the bladder until it is ready to be excreted. Therefore option D is the correct answer.

The direction of effects for each quantitative trait locus is consistent, indicating that the teeth and jaws of cichlids evolved in response to significant divergent selection.

Divergent evolution is the process through which various organisms with shared ancestors evolve unique traits or characteristics to meet the needs and conditions of their changing environments.

Divergent evolution refers to the sharing of a common ancestor by two or more separate species before their divergence. Modern elephants and woolly mammoths are two frequent examples. Despite having a common ancestry, they have diverged into two distinct species. The dog, the wolf, and the fox are three other examples.

The frequency of gene crossing over is often inversely correlated with the distance between the genes.

The genetic distance between two genes, measured in map units (m.u. ), is correlated with the frequency of gene crossing over or recombination.

In this instance, we can calculate the likelihood of crossing over as 40% if two genes are 40 m.u. apart. This indicates that a crossover event between these two genes should occur in about 40% of meiocytes, the cells that divide during meiosis to produce gametes.

It's crucial to remember that this assessment is predicated on the premise that the genes are unrelated, and the crossover events happen independently. Factors like genetics can affect the actual frequency of crossing over.

The reason for the relatively fewer antifungal agents compared to antibacterial agents is that it is difficult to attain selective toxicity for fungal diseases versus bacterial diseases.

Fungi and bacteria are both types of microorganisms that can cause infections, but they have different cellular structures and metabolic processes. Targeting fungal cells specifically while avoiding harm to human cells is more challenging due to the similarities between fungal and human cells compared to bacterial cells. Achieving selective toxicity, where the agent effectively kills the pathogen while sparing the host, is more complex for fungal diseases.

Additionally, the development of antifungal agents requires a deep understanding of the unique aspects of fungal biology and metabolism. This complexity adds to the difficulty of discovering and developing effective antifungal medications.

Therefore, the limited number of antifungal agents is primarily due to the challenge of achieving selective toxicity for fungal diseases compared to bacterial diseases.

Cooperation between different prokaryotic species occurs in surface-coating colonies called biofilms.

Biofilms are complex and structured communities of microorganisms, including bacteria and archaea, that adhere to surfaces. In biofilms, different species of prokaryotes work together in a coordinated manner to form a cooperative community. They interact and communicate through various chemical signaling mechanisms, sharing resources and carrying out specialized functions within the biofilm. This cooperation allows the biofilm to exhibit enhanced resistance to environmental stresses, improved nutrient acquisition, and increased protection against antimicrobial agents.
