Winston cannot taste the wine he is offered, because of all the gin he had drunk throughout his life. what is the rhetorical effect of this?

Answers

Final answer:

The statement about Winston not being able to taste wine because of his excessive gin consumption is a rhetorical device known as hyperbole. It uses sensory detail and exaggeration to highlight the severity of his alcoholism.

Explanation:

The rhetorical effect of Winston not being able to taste the wine due to his life-long gin consumption is twofold. First, it serves as an instance of hyperbole, an exaggerated statement not meant to be taken literally, to stress the extensive gin consumption. Second, it uses sensory detail to depict the impact of his drinking habit not merely in abstract terms, but in a way that readers can relate to on a physical, sensory level. This strategy effectively conveys the severity of his alcoholism and its long-term effects.

The answer to this question would be: D. Taenia saginata; tapeworm

Taenia saginata is also known as beef tapeworm because it can infect cattle. The worm that infects the cattle can travel into their muscle and transform into infective larvae. A human can be infected by taenia saginata if they eat uncooked beef meat that was infected by the worm. 

In the winter, icy roads are often salted to remove the ice and make them less slippery. grasses and other herbaceous plants often die near the side of these roads. what causes this to happen?

Answers

Grass often dies near roads that have been salted to remove ice during the winter because the salt spread out into layer of the grass cell. Then the water goes into the ice because the grass is attracted to the salty ice water. Hence, this dehydrates the plant cell by removing excess water, so it dies since it can no longer perform the proper cell function.

If you could know that a fossil that is 10,000 years old started with 20 mg of carbon-14, how much would you expect that same fossil to have today?

Answers

The half life of Carbon 14 is 5730 years. By substituting the given figures to the formula x=I(1/2)^n where x is the amount of the remaining material, I is the initial amount and n is the quotient between the time elapsed and carbon 14's halflife. You will arise with the formula x=20(1/2)^1.745. You will get 5.97 mg.

Vitamin e protects membranes in red blood cells, white blood cells, nerve cells, and lung cells. why are these cells in particular in need of high amounts of vitamin e?

Answers

Answer:

Vitamin E supplements may prevent coronary heart disease , support immune function, prevent inflammation , promote eye health, and lower the risk of cancer.

Red blood cells, white blood cells, nerve cells, and lung cells need high amounts of vitamin E due to their high polyunsaturated fatty acid content and exposure to oxidative stress. Vitamin E acts as an antioxidant, preventing lipid peroxidation in cell membranes and working in conjunction with selenium to maintain cellular health.

The cells such as red blood cells, white blood cells, nerve cells, and lung cells require high amounts of vitamin E because they are particularly susceptible to oxidative damage from free radicals. Vitamin E serves as a powerful antioxidant that protects the polyunsaturated fatty acids present in the cell membranes from oxidation. The cells' high degree of unsaturation in their membrane lipids makes them vulnerable to lipid peroxidation, which can be detrimental to their function and integrity.

Vitamin E, especially in the form of alpha-tocopherol, prevents the oxidation of these fats by acting as a free radical scavenger. It donates electrons to free radicals, stopping the chain reaction of lipid peroxidation. In addition, vitamin E works by sparing or reducing the need for, selenium, which is needed for the activity of glutathione peroxidase, an enzyme that also reduces lipid peroxides and protects the cell membrane. This synergistic action is essential for maintaining cellular health, especially in cells that are exposed to higher levels of oxidative stress, such as lung cells which are constantly in contact with oxygen, and white blood cells that engage in immune responses.

perform functions that tissues cannot carry out on their own

Explanation:

In the hierarchy of living system organs come after tissues and before organ systems. Hence, organs are complex then tissues and perform functions that tissues wont be able to perform on their own.

A organ is made up of various types of tissues. They can be divided into two categories, main tissue and sporadic tissue. Main tissue or parenchyma is unique to that organ and defines the function of the organ. For example: Cortex and medulla together form the main functional tissue in kidney. Similarly, myocardium is the main tissue of the heart. Sporadic tissue has blood vessels, nerves and connective tissues.

Answers

Just divide 720 / 4. The answer is C. 180. :)

Answer:

It will take C. 180 years to grow 720 millimeters.

Explanation:

The research shows that Mount Everest grows and average of 4 millimeters each year.

In order to calculate how many years it will take to grow 720 millimeters, we need to divide 720 millimeters by the average of 4 millimeters each year.

If we calculate it :

[tex]\frac{720mm}{4\frac{mm}{year}}=180years[/tex]

We found out that it will take 180 years. Therefore, the correct option is C. 180

Answers

period marks the end of one menstual......

Answer:

Menstrual flow and ovulation

Explanation:

The menstrual cycle is the hormones regulated the complex process. In this process, endometrium (a thickened lining of uterus wall) ruptures. Rupturing of endometrium results into the menstrual fluid which contains blood, cells from the lining of the uterus and mucus. The flow of menstrual fluid from the vagina is called menstruation. This process is to prepare the woman for expected fertilization.

Menstruation marks the end of one cycle and the release of ova from one of the ovary is beginning of next menstruation that occurs almost 14 days before menstrual flow.

Hypothesize what potential impact a mutated egfr allele will have on a cell

Answers

Epidermal Growth Factor Receptor or EGFR is a factor that controls growth in epidermal cells. EGFR will induce division of cells so they are important in cell growth. In there is a mutated EGFR allele, the synthesis of EGFR might be disrupted causing increase/decrease to the growth factor.
If the mutation causing an increase of EGFR then you can hypothesize that the person will be increased risk to developing a cancer. 

Mutated EGFR can lead to cancer (especially lung cancer).

A mutation in EGFR is associated with uncontrolled tumor growth, which can accelerate cancer progression.

Epidermal Growth Factor Receptor (EGFR) receptors are found on the surface of tumor cells and their role is to send a growth signal to the nucleus of the cell. Some lung cancer tumors may contain a mutation in their DNA that affects the EGFR. The tumor is said to be "positive for EGFR mutations".

Tumor cells with EGFR mutations are highly sensitive to cancer treatments called "Targeted Therapies" or "EGFR Tyrosine Kinase Inhibitors".

As the organism inside the respirometer consumes oxygen what happens to the water

Answers

As O 2 is used up, the pressure of gases inside the respirometer decreases. Then CO 2 that is produced combines with KOH to form a solid precipitate.

Answer:

A respirometer is a device that is used to measure the consumption rate of oxygen by any living organism.

So as the oxygen uses by the organism, the pressure of oxygen in the respirometer decreases and as the pressure decrease some amount of water enters the respirometer.  

So according to the consumption of oxygen water will move inside the respirometer due to a reduction in pressure in respirometer. So the rate of respiration can be calculated because the amount of water enters is directly proportional to the amount of oxygen consumed by an organism.

Viruses can survive refrigerator and freezer temperatures true or false

Answers

Final answer:

Viruses are capable of surviving in low temperatures, including those found in refrigerators and freezers. They do not proliferate under such conditions, though, as they need living host cells to replicate.

Explanation:

Yes, the statement that viruses can survive refrigerator and freezer temperatures is true. Viruses are not living organisms in the conventional sense, thus they don't have a metabolic rate that can be affected by temperature. Instead, they exist as particles and can remain infectious in a variety of conditions, including low temperatures such as those of a refrigerator or freezer. For instance, the influenza virus and the Covid-19 virus can both survive in cold temperatures. However, this varies between different types of viruses. While they can survive, they do not proliferate in these conditions because they require living host cells in order to replicate.

Final answer:

Yes, viruses can survive both refrigerator and freezer temperatures. Their ability to reproduce is often inhibited at low temperatures, but many can remain dormant or resilient. However, extreme cold can lead to physical changes in these viruses, which might inhibit their ability to infect host cells.

Explanation:

Yes, the statement that viruses can survive both refrigerator and freezer temperatures is true. Some viruses, like certain types of influenza, have shown the ability to survive outside of a living host cell for extended periods of time, sometimes from 48 hours to 17 days. On the other hand, some pathogens like cold-causing rhinoviruses are more fragile and tend to survive for a shorter duration, typically less than a day.

When exposed to low temperatures, pathogens do not typically reproduce, but they can remain dormant or resilient. Refrigerator temperatures, which range from 0 °C to 7 °C, slow down microbial metabolism, inhibiting growth and helping to preserve the pathogen. Similarly, even ultra-low temperatures of -70 °C or lower can be withstood by some types of pathogens for extended periods.

However, extreme cold temperatures can lead to physical changes in viruses, affecting membrane fluidity and other biological processes. These changes may inhibit the ability of the virus to infect host cells. Thus, while cold temperatures do not universally destroy viruses, they can very often inhibit their ability to infect host cells because of the changes in membrane fluidity and the slowing down of biological processes.
