Which of the following is not an effective way to prevent heat stress and stroke? A. Wear a minimum of SPF 15 sunscreen. B. Take a 10-minute rest for every 45 minutes of activity. C. Wear loose-fitting clothing that allows sweat to evaporate. D. Drink water before, during, and after a workout.
Answer:
A. Wear a minimum of SPF 15 sunscreen.
Explanation:
One of the main problems that can be caused by heat is thermal stress, which occurs when the body's internal temperature is overloaded and unable to maintain the ideal temperature. In general, any environment or circumstance that exposes the body to heat sources above 35 ° C can cause physical and mental changes in the worker and may even cause stroke.
Some ways to avoid heat stress and stroke are to rest 10 minutes for every 45 minutes of activity, wear loose clothing that allows sweat to evaporate and drink water before, during and after a workout. The use of sunscreens and sunblocks is not effective in avoiding heat stress and stroke, because these products have the sole function of protecting the skin from solar radiation.
"A. Wear a minimum of SPF 15 sunscreen" is not an effective way to prevent heat stress and stroke.
Heat stress often leads to heat stroke. When the body is exposed to too much heat than it can regulate, dehydration sets in and the body temperature goes above the normal body temperature. This results to heat stress.
As a result of heat stress and the inability of the body to control its temperature, organs of the body begin to shut down. When this occurs, heat stroke sets in.
Effective ways to prevent heat stress and stroke includes:
Taking rest at intervals to avoid burnouts.Drinking water often when before, during and after working out to prevent dehydration.Wearing cloths that allows sweat to evaporate which cools the body.All these aims at ensuring the body temperature is kept at favorable limits and also ensure the body is not dehydrate to prevent heat stress and stroke.
However, "A. Wear a minimum of SPF 15 sunscreen" is not an effective way to prevent heat stress and stroke.

When a skeletal muscle contracts, which site undergoes the greatest movement?
A. Origin of the muscle
B. Insertion of the muscle
C. Head of the muscle
D. Belly of the muscle
Final answer:
The greatest movement during a skeletal muscle contraction occurs at the muscle's insertion, as opposed to the origin, which is fixed to a bone and generally does not move. Option B
Explanation:
When a skeletal muscle contracts, the site that undergoes the greatest movement is the muscle's insertion. The insertion is the end of the muscle that is attached to the bone that moves during contraction. In contrast, the origin is the end of the muscle attached to a fixed or stabilized bone and generally does not move as much or at all during contraction. Therefore, the correct answer to the question is B. Insertion of the muscle.
The location of a muscle's insertion and origin can determine various factors such as action (what movement it produces), the force of contraction, muscle name (often based on the origin and insertion points), and the load a muscle can carry.

Answer:
d. all of the above
Explanation:
Deviance in sociology means behaving in ways that violate social norms and provoke negative social reactions. It is important to emphasize that the concept of deviant behavior is relative - it depends on the society and the time in which it occurs.

Obesity is often seen by the general public as a character flaw. Why is this perception a misunderstanding of both the biological and psychological aspects related to obesity? What steps can be taken to educate people on the problem?
Answer:
The perception of the fact that obese people do not take care of themselves and are responsible for their ill health is prevailing for long. There are perceptions of certain sections of society is that obesity is related to poor lifestyle choices. However, that may not be the case at all times because Stress, sleep health, hormones, chronic pain, underlying medical conditions, medications, genetics, and multiple other environmental and economic factors are some of the primary reasons which do contribute to obesity and one may not be voluntarily doing that to themselves. There is also a notion that weight loss will reduce obesity and an obese person may again function as a person who has a perfect body weight. This may also not be true because just weight loss does not solve the problem, the human metabolism has a method to function and losing too much weight at once can disrupt the body's energy systems and might cause physical complications and it can also cause psychological stress , increased muscle loss can take place and in turn there is a risk of our metabolism getting lower.
So what can be noted is that a huge section of the society we live in are not aware and well educated about the problems and causes related to obesity and thus tend to loosely comment and also there are individuals who believe that negative criticism can bring about a positive change in individuals.
The steps which can be taken to educate people about the misconceptions of obesity is that -
Firstly educate them about what obesity is how it is caused and what are the biological and psychological consequences to it.
Secondly create mass awareness program related to obesity to prevent the stereotype which is prevailing
Thirdly conduct group support sessions for helping with problems related to obesity.
Lastly make people understand that negative criticism is a strict no-no and that never motivates them instead come up with optimistic advices which would boost their confidence and make them strong willed in their journey to get rid of obesity.
Explanation:
A neuron that sends information is a ______ neuron; a neuron that receives information is a _____ neuron.
-presynaptic; postsynaptic
-a priori; post hoc
-sensory; motor
-postsynaptic; presynaptic
(C) sensory; motor
EXPLANATION:The dendrites of neurons receive information in the form of impulse by the sensory receptors. This sensory information is then transferred to the spinal cord and brain through the nerve fibers in the sensory nerve. On the other hand, the motor neurons receive the impulse and control the action of the glands and muscles. Synapse is a junction between the meeting point of two nerve cells.
A neuron that sends information is a presynaptic neuron, while a neuron that receives information is a postsynaptic neuron. They work together to transmit signals throughout our body.
Explanation:In the context of neurobiology, a neuron that sends information is referred to as a presynaptic neuron; a neuron that receives information is defined as a postsynaptic neuron. Information in the presynaptic neuron travels down its axon in the form of electrical impulses called action potentials. When these action potentials reach the synapse, they trigger the release of neurotransmitters, which are then picked up by the postsynaptic neuron. The postsynaptic neuron converts this chemical signal back into an electrical signal, allowing the information to continue on its path.

Which of these individuals has sedentary lifestyle?
Individuals with a sedentary lifestyle are characterized by prolonged periods of sitting, driving, or using digital devices, leading to health risks such as heart disease and increased mortality rates. Active attempts to introduce moderate-intensity physical activities can mitigate these risks.
Explanation:A person with a sedentary lifestyle is someone who engages in activities that do not meet the physical activity guidelines set by the US Surgeon General's Report, thus increasing their risk of heart disease. This lifestyle often includes prolonged periods of sitting, reclining, or lying down during waking hours. Examples of sedentary behavior include desk-based office work, driving a car, watching television, playing video games, and checking social media.
Sedentary behavior can lead to numerous health risks, including increased risk of overall mortality, cardiovascular disease, and certain types of cancer. Communities that lack walkable or bikeable infrastructure contribute to this issue, as residents are forced to drive, thus increasing sedentarism. Increasing physical activity by incorporating moderate-intensity activities can reduce health risks associated with a sedentary lifestyle.
No matter how much time those with sedentary lifestyles spend in light-intensity activity, it is the moderate-intensity physical activity that counts towards improving health. Hence, those who do not engage in moderate- or vigorous-intensity physical activities are considered inactive.
As you get older, it will become harder to eat whatever you want and maintain a healthy weight. This is because your basal metabolic rate, or BMR, ________ as you age. A. increases B. decreases C. stays the same D. disappears
As you age, your basal metabolic rate (BMR), which is the number of calories your body needs when at rest, decreases. This is because of the natural loss of lean body mass. If calorie consumption remains the same but BMR decreases, this can lead to weight gain.
Explanation:Your basal metabolic rate (BMR) is essentially the number of calories your body needs to perform basic functions while at rest. This includes breathing, circulating blood, and regulating body temperature. As you grow older, your BMR decreases. This is primarily due to a natural loss of lean body mass as you age. When your BMR is lower, your body needs fewer calories to perform these essential functions. Therefore, if you continue to eat the same amount of food as you age without increasing physical activity, you are likely to gain weight as your metabolic rate has slowed.
