Intuition might tell us that rough surfaces on clothing would inhibit the speed of an Olympic athlete. Why is this line of thinking not true in some cases? How can controlled roughness actually promote speed? Write a paragraph that is about 100 words long.

Answers

Answer 1
Intuition might tell us that rough surfaces on clothing would inhibit the speed of an Olympic athlete. It is not true in some cases because rough clothing could not inhibit the performance of an athlete. If the athlete however had the experience first hand while during practice, in wearing such rough outfits then it would not inhibit his performance during his competition. But, if during the competition, he suddenly had to wear a smooth clothing, then he would have a hard time dealing with it during his competition because it is not the one that he had his practice on. So in short, it all boils down on how people adapt to these things and how well they can execute certain things that are not common to everybody. Maybe for some, if they had the time to practice using smooth clothing then it would not be a problem with promoting with their speed.
Answer 2

People might think that clothing with rough surfaces slows down movement because the rough parts trap air. That's not always the case. By controlling the amount of roughness, it’s possible to allow air to pass more easily over the fabric. The shape of a golf ball is based on this idea: the dimples on its surface make the air spin in small circles, like mini vortexes. These spinning circles of air act like ball bearings in a machine. The overall effect is that the ball can move more easily through the air, so it flies a greater distance. In the same way, the grooves on athletes' clothing also allow smoother movement through the air.

Which drugs are most likely to be prescribed as tranquilizers?
a. amphetamines
b. hallucinogens
c. opiates
d. barbiturates?

Answers

I believe the anwser is c
Final answer:

Barbiturates are most likely to be prescribed as tranquilizers, although benzodiazepines are commonly used as well for their reduced toxicity and effectiveness in short-term relief of severe conditions.

Explanation:

The drugs that are most likely to be prescribed as tranquilizers are barbiturates. Barbiturates are central nervous system depressants that can reduce anxiety and induce sleep. These drugs have largely been replaced by benzodiazepines in regular medical practice (particularly in the U.S.), because benzodiazepines are generally less toxic and still effective for short-term relief of severe, acute conditions. Any drug in these categories may be referred to as a tranquilizer.

Explain why antibodies allow scientists to target and identify specific disease agents.

Answers

Explain why antibodies allow scientists to target and identify specific disease agents.
Antibodies is a protein that has the ability to bind to a specific structure of another protein called antigen. It can bind that specific structure because protein(like enzyme) has a complex 3D structure. That makes a slight difference in the structure of molecule will cause it unable to bind with the antibodies. This feature called  "lock and key" and used in ELISA or any test that count antibody/antigen
Final answer:

Antibodies allow scientists to target and identify specific disease agents by binding to antigens on the surface of the disease agents. They can be used for diagnostic purposes and to distinguish between different strains or variants of a disease.

Explanation:

Antibodies allow scientists to target and identify specific disease agents because they are highly specific proteins produced by the immune system in response to foreign substances like pathogens. They recognize and bind to antigens, which are unique molecules found on the surface of disease agents. This binding allows scientists to detect and identify the presence of specific disease agents in samples or tissues.



For example, in the case of a viral infection, scientists can use antibodies to specifically target and identify the viral particles or proteins associated with the virus. They can also use antibodies to distinguish between different strains or variants of a particular disease agent.



Scientists can harness the specificity of antibodies for diagnostic purposes, such as in serological tests. These tests detect the presence of antibodies produced by the immune system in response to a specific disease agent. By measuring the levels of specific antibodies in a patient's blood, scientists can determine if the patient has been exposed to a particular disease and may have developed immunity.

Which of these is a sexual stereotype?
A)on average, females weigh less than males.
B)lesbians usually wear there hair short.
C)women have twice as many X chromosomes as men.
D)female hormone levels differ from those of males.

Answers

The correct answer is B) Lesbians usually wear their hair short because it is an oversimplified generalization about a specific group.

In this question, we need to identify a sexual stereotype.

A stereotype is a widely held but fixed and oversimplified idea or image about a particular group. Let's examine each option:

On average, females weigh less than males. - This is a factual biological difference between sexes and not a stereotype.Lesbians usually wear their hair short. - This is a stereotype because it is an oversimplified and generalized idea about a specific group based on their sexual orientation.Women have twice as many X chromosomes as men. - This statement is biologically inaccurate. Women have two X chromosomes, while men have one X and one Y chromosome.Female hormone levels differ from those of males. - This is another factual statement based on biological differences.

Therefore, the statement "Lesbians usually wear their hair short" is the example of a sexual stereotype.

In order for pests to feel comfortable and survive well in a food facility they need access to

Answers

Food, water and shelter

Pests invade human places in order to obtain the resources they require for survival, namely food, water and shelter. Therefore, if pests obtain access to these resources, they are likely to stay and reproduces, resulting in an increase in pest population in the area. Therefore, the best measure for preventing pest infestation is to prevent access to such resources.
Final answer:

Pests require food, a suitable environment, and the absence of natural enemies to thrive in food facilities. Landscape complexity enhances the natural pest control by a variety of predators, reducing the need for pesticides. Maintaining diversity among these predators is crucial for efficient agriculture.

Explanation:

In order for pests to survive well in a food facility, they need access to adequate food sources, a suitable environment, and typically, a lack of predators or pest-suppressing organisms. Ecologists have noted that predators and parasites are essential in controlling pest populations and thereby reducing the reliance on costly and potentially harmful pesticides. Landscape complexity plays an important role in this regard, as it enhances the effectiveness of natural enemies of pests in suppressing these populations, which can lead to increased crop yields. It is observed that diverse ecosystems are more effective at pest control as compared to those with reduced enemy diversity.

Pests, like many organisms, require sufficient quality and quantity of food for their dietary needs. In colder climates, for example, the availability of food for pests typically decreases, setting a requirement for a threshold level of energy to be stored as fat for their survival. However, in warmer climates, certain pest-resistant plant species may thrive and provide a more comfortable environment for pests. Maintaining a diversity of predatory species is crucial since a loss of diversity among natural enemies of pests can make agriculture more difficult and expensive.

Such adjustment in judgment has subsequently made liquor to fill in as an enhancer of homicide, which is presently perceived as a reason for untimely mortality in Africa. Alcohol improves the probability of hazard taking and provocative conduct by some potential exploited people; this may thus prompt violent communications and homicide.

A muscle contraction that results in no movement of the body is referred to as a(n) ________ contraction.

Answers

A muscle contraction that results in no movement of the body is referred to as an isotonic contraction. The isotonic contraction can be concentric and eccentric. Concentric contraction results in the muscle shortening, because the force the muscle is producing is greater than the resistance. Eccentric isotonic contraction on the other hand results in muscle lengthening because the resistance is being greater than the force the muscle is producing.

Final answer:

An isometric contraction is when muscle tension increases but there is no movement because the muscle does not change length. It differs from an isotonic contraction, where there is movement due to changes in muscle length while tension remains constant.

Explanation:

A muscle contraction that results in no movement of the body is referred to as an isometric contraction. During an isometric contraction, muscle tension increases but muscle length remains the same. It is a static contraction where the length of the muscle, or the joint angle, does not change, such as when pushing against a stationary object. An example of an isometric contraction in everyday life includes maintaining posture or bone and joint stability. Contrary to this, an isotonic contraction means the muscle changes length (shortens or lengthens) while the tension remains constant. Therefore, an isometric contraction is characterized by the generation of force without movement, and by the fact that during the contraction, the muscle neither lengthens nor shortens.

Give a summary of the guidelines for using sunscreen to prevent overexposure

Answers

Make sure to apply a sunscreen of at least 30 SPF or higher to be safe from UV rays. Make sure to apply topically evenly and generously. Reapply after 2 hours, swimming, or drying.

Guidelines for using sunscreen to protect from overexposure are:

1. Choose the appropriate type of sunscreen: This choice should be according to your type of hair. There are sunscreens of drier texture and others of oily texture, you must choose the one that best fits the natural characteristics of your skin.

2. Choosing the protection factor: When sun exposure is intentional - such as on the beach or in the pool - the sun protection factor (SPF) should be at least 30. However, people with fair skin, or who have very sensitive skin should use protectors with a protection factor of, at least, 50.

3. Know the right amount: When there is an intentional exposure, such as when going to the beach or pool, the correct way to use sunscreen is to apply two layers of the product all over the body or a teaspoon for face, head and neck; two teaspoons to the front and back of the torso; one teaspoon for each arm and two teaspoons for each leg. Sunscreen should be applied 15 minutes before sun exposure and reapplied every two hours while exposed.

Final answer:

The first step after installing a field-piped R-410A split heat pump is to evacuate and properly charge the unit with refrigerant. This ensures proper function and efficiency. Subsequent testing and the use of a programmable thermostat can further enhance the system's efficiency.

Explanation:

After the installation of a field-piped R-410A split heat pump, the unit should first be properly evacuated and then charged with refrigerant according to the manufacturer's specifications. It's important to ensure that all pipe connections are secure and there are no leaks. Once checked for leaks and the system is correctly evacuated, you can proceed with charging the refrigerant, which is a critical step as R-410A is a high-pressure refrigerant. After this, a performance test to check if heat transfer efficiency is optimal would be appropriate.

The process of charging a split heat pump system involves connecting the refrigerant supply to the service port and adding refrigerant until the desired pressure is reached. Precise procedures can vary depending on specific system requirements and manufacturer guidelines. It's essential to use equipment such as gauges and a vacuum pump that is compatible with R-410A. Additionally, the correct type and amount of refrigerant must be verified to match the needs of the system functionality.

Implementing features like a programmable thermostat can enhance efficiency by reducing the operation of the system when not needed. Regular maintenance of the system is also important to ensure that the split heat pump operates at peak efficiency, conserving energy and reducing costs in the long term.

Answer:

Resistance stage.

Explanation:

The resistance stage is the second stage of the body's stress response. This stage begins when the body attempts an adaptation due to its tendency to seek internal homeostasis, ie the body tries to return to its normal state. In the “resistance phase”, the reactions are opposite to those in the first phase, and many of the early symptoms disappear, giving rise to a feeling of weariness and tiredness. If the stressor is continuous and the person has no strategies for coping with stress, the body depletes its adaptive energy reserve and moves on to the next stage.
