the hiv drug azidothymidine (azt) has what mechanism of action?choose one:a. it is an integrase inhibitor.b. it is a protease inhibitor.c. it is a reverse transcriptase inhibitor.d. it blocks the cd4 receptor.
Answers
The HIV drug azidothymidine (AZT) has it is a reverse transcriptase inhibitor mechanism of action.
Azidothymidine, generally known as zidovudine or AZT, is a medication used to prevent HIV-positive people from developing AIDS (acquired immunodeficiency syndrome). The class of medications known as nucleoside reverse transcriptase inhibitors (NRTIs) includes AZT. The U.S. Food and Drug Administration granted the first of these medications, AZT, approval in 1987 with the goal of extending the lives of AIDS patients.
Only when HIV is reproducing into proviral DNA—viral DNA that has not yet been integrated into host DNA—does AZT become effective against it. This is due to the fact that AZT's active ingredient, zidovudine 5-triphosphate, has a high affinity (attraction) for the reverse transcriptase enzyme that retroviruses like HIV employ to generate viral DNA.

4. Question - HW-04: How much will a granite intrusion reset radiation damage and cooling age of zircons in the surrounding rocks? A. Closer to the source zircons will show fully reset cooling ages B.
Answers
It's important to note that the effects of a granite intrusion on zircons and surrounding rocks can vary widely depending on the specific geological conditions and the characteristics of the intrusion.
A granite intrusion can have a significant impact on the surrounding rocks, including the zircons within them. However, the specific effects on the zircons' radiation damage and cooling ages will depend on various factors, such as the temperature and duration of the intrusion, as well as the distance from the source.
A. Closer to the source: Zircons that are closer to the source of the granite intrusion may experience higher temperatures and longer durations of exposure to the intrusive event. In such cases, it is possible for the zircons to show fully reset cooling ages. The high temperatures can cause the zircons to undergo recrystallization or complete annealing, effectively resetting their cooling ages to the time of the intrusion. Additionally, the thermal energy from the intrusion may partially or completely anneal the radiation damage accumulated in the zircons, further resetting their radiation damage signatures.
B. Farther from the source: Zircons that are farther away from the source of the granite intrusion will experience lower temperatures and shorter durations of exposure. In such cases, the zircons may not undergo complete recrystallization or annealing, and their cooling ages may not be fully reset. The degree of cooling age reset will depend on the specific thermal history and proximity to the intrusion.
It's important to note that the effects of a granite intrusion on zircons and surrounding rocks can vary widely depending on the specific geological conditions and the characteristics of the intrusion. Local geological studies and analyses would provide a more accurate assessment of the impact of a specific granite intrusion on zircons in the surrounding rocks.

__________ is tissue necrosis commonly caused by poor circulation to the affected area.
Answers
Gangrene is tissue necrosis commonly caused by poor circulation to the affected area. It is a serious condition that can lead to amputation of the affected body part if left untreated. The lack of blood flow to the affected area can be due to various reasons like arterial blockage, blood vessel damage or injury, infection, and more.
There are two types of gangrene, dry and wet. Dry gangrene usually affects the extremities like fingers, toes, and feet. It develops gradually and is more common in people with diabetes or vascular disease. It presents with symptoms like skin discoloration, cold and numb extremities, and severe pain. Wet gangrene is a more severe type that usually affects the internal organs or tissues. It occurs when the affected area becomes infected with bacteria and can spread rapidly. Symptoms include swelling, fever, and foul-smelling discharge.
Gangrene can be prevented by maintaining good hygiene, avoiding tobacco use, controlling diabetes and high blood pressure, and seeking prompt medical attention for any injury or infection. Treatment involves restoring blood flow to the affected area, removing dead tissue, and preventing the spread of infection. In severe cases, amputation may be necessary.

The cut of a guillotine is an example of a section done in the midsagittal plane. (TRUE/ FALSE)
Answers
The given statement "The cut of a guillotine is an example of a section done in the midsagittal plane." is false because the cut of a guillotine is not an example of a section done in the midsagittal plane.
The midsagittal plane, also known as the median plane, is a vertical plane that divides the body into equal left and right halves. It passes through the midline of the body, including the head, neck, and trunk. A section done in the midsagittal plane would result in two equal halves.
In the case of a guillotine, the cut is made in a horizontal plane, severing the head from the body. This type of cut is not in line with the midsagittal plane. Instead, it would result in sections that are not symmetrical, as the cut is not along the midline of the body.
The guillotine cut would be more accurately described as a transverse or horizontal section, as it separates the body into superior and inferior parts. This type of section is perpendicular to the sagittal and midsagittal planes.
In summary, the cut of a guillotine is not an example of a section done in the midsagittal plane. It is a transverse or horizontal section that divides the body into superior and inferior portions. Hence the statement is false.

List 3 everyday examples of the cohesive and/or adhesive properties of water.
Answers
Adhesive force is the force of attraction that exists between the molecules of two different substances. This force helps to bind the two objects together.
3 everyday examples of adhesive properties of water:-
Painting: Applying a coat of paint on the walls or any furniture is the perfect example of adhesive force in action.
Wet Surface: When water falls on any surface, it spreads out thoroughly. This spreading of water causes an intermolecular attraction to get developed between the water molecules and the surface molecules.
Capillary Action: If you place a thin straw in a glass of water, the water will be attracted to it. If the adhesive attraction between the water and straw is stronger than the water's cohesive attraction with itself, water will move up the straw unassisted. This is how plants bring water from the soil up into their leaves.
Cohesion on the other hand is the intermolecular (between-molecules) attraction between molecules of the same type, which in this case is the attraction between molecules of water.

Expression of the trp operon is regulated by the level of free tryptophan in the cell both through repressor action and attenuation. This chart shows the percent expression of the trp operon in the presence and absence of tryptophan for wild-type (trpR+ or trp+) and repressor mutants (trpR-). Use this information to determine the levels of expression for the following genotypes and conditions. Rank the genotypes and conditions from highest to lowest level of trp operon expression.
Answers
Based on the chart provided, the ranking of trp operon expression from highest to lowest would be:
trpR- in the absence of tryptophan
trpR+ in the absence of tryptophan
trpR- in the presence of tryptophan
trpR+ in the presence of tryptophan
The highest expression of the trp operon occurs in the absence of tryptophan in the presence of the repressor mutant (trpR-), since the repressor protein is not functional in this case and cannot inhibit the expression of the operon.
The second highest expression occurs in the absence of tryptophan in the wild-type strain (trpR+), since there is no tryptophan to bind to the repressor protein and inhibit its action.
The third highest expression occurs in the presence of tryptophan in the repressor mutant (trpR-), since even though the repressor protein is not functional, the attenuation mechanism can still regulate the expression of the operon.
The lowest expression occurs in the presence of tryptophan in the wild-type strain (trpR+), since the repressor protein is active and can bind to tryptophan, inhibiting the expression of the operon.

Option (1) is correct. We recognise that those lizards' species belong to identical genus Norops. These 3 species i.e. Norops sagrei, Norops valencienni and Norops auratus have to be residing withinside the most important island.
Intraspecific opposition for meals and habitat brought about the separation of those species. Island is lengthy in the past earlier than of them moved into new islands. Apart from this, weather is likewise an crucial element because of which species separate and inhabit islands. Like on this case, Norops sagrei and Norops valencienni occupied separate islands toward the North America. However, Norops auratus is found to be increasing its variety from South to North America.
This is due to particularly warm weather of the mainland which lizards aren't capable of tolerate. As a result, species Norops auratus is moving toward the chillier regions withinside the North America.

Correct Question:
at what age does your brain reach 90 percent of its adult weight?
Answers
Answer: Age 5.
Explanation: Incredibly, it doubles in size in the first year. It keeps growing to about 80% of adult size by age 3 and 90% – nearly full grown – by age 5. The brain is the command center of the human body.
According to neuroscience, the human brain reaches 90 percent of its adult weight at around the age of six years.
Although the brain remains to grow for several years, the vast majority of its growth occurs in the first few years of life. The growth of the brain takes place more in terms of development than in size. The increase in brain size in the early years of life is mostly because of the growth of neural connections. A child's brain continues to develop and grow over time and adolescence, however, the pace of growth decreases with age as the number of neural connections reduces.
In the first two years of life, the brain doubles in size and continues to grow rapidly until about the age of six years. The brain reaches almost its full adult size by the time a person is six years old. However, the neural connections in the brain continue to develop throughout life as the brain experiences new things and learns new skills. Thus, the human brain never stops changing, and it is capable of growing and adapting throughout the individual's lifespan.

Lila is a track and field athlete. She must complete four laps around a circular track. The track itself measures 400 meters from start to finish and the race took her 6 minutes to complete. Which best describes her speed and velocity? (There are 60 seconds in 1 minute.)
Answers
Answer: Her speed is 4.4 m/s, and her velocity is 0 m/s.
Explanation:
Formulae :\(\text{Speed}=\dfrac{\text{Distance}}{\text{Time}}\)
\(\text{Velocity}=\dfrac{\text{Displacement}}{\text{Time}}\)
Given: Length of track start to finish= 400 meters
After completing its 4 laps, total distance covered = 400 × 4 = 1600 meters
Time taken by Lila = 6 minutes
= 6 × 60 seconds [There are 60 seconds in 1 minute.]
= 360 seconds
Then, \(\text{Speed}=\dfrac{1600}{360}=\dfrac{40}{9}m/s\)
\(= 4.44\ m/s\)
But from start to finish displacement = 0 m [displacement is the shortest distance between starting point to the finishing point]
So, \(\text{Velocity}=\dfrac0{360}=0\ m/s\)
Hence, Her speed is 4.4 m/s, and her velocity is 0 m/s.

Answers
The estimated temperature when the crickets are chirping at 156 chirps per minute is 27.5 degrees Fahrenheit.
What is the equation that models the relationship between temperature and the number of chirps?The linear equation that models the relationship between temperature and the number of chirps is T(N) = -0.5N + 105.5.
In this given case, if the crickets are chirping at 156 chirps per minute, we can estimate the temperature by substituting N = 156 into the equation and solving for T.
By substituting N = 156 into the equation T(N) = -0.5N + 105.5, we find:
T(156) = -0.5(156) + 105.5
T(156) = -78 + 105.5
T(156) = 27.5
Therefore, the estimated temperature when the crickets are chirping at 156 chirps per minute is 27.5 degrees Fahrenheit.
