Which measurement determines body frame size?
Question 2 options:


wrist circumference


hip-to-waist ratio


body mass index


bust-to-waist ratio

Answers

Final answer:

Wrist circumference is the measurement that determines body frame size, distinguishing between small, medium, or large body frames.

Explanation:

The measurement that determines body frame size is wrist circumference. Other measurements like hip-to-waist ratio, body mass index (BMI), and bust-to-waist ratio can provide information about body fat distribution and health risks but are not used to determine body frame size. Wrist circumference is commonly used for assessing the size of the body frame; small, medium, or large frame can be classified based on the circumference of the wrist relative to the person's height.

how does the anatomy of a knee differ from the anatomy of a elbow

Answers

Your knee has a knee cap while your elbows do not. The elbow also contain less cartilage and and ligaments.

The elbow's ability to pronate and supinate , knees don't. This distinguishes the two joints.

What is a joint ?

A joint is a part of the body that allows movement and is formed when two or more bones join. In general, the greater the range of movement, the higher the risk of injury because the strength of the joint is reduced. The ball-and-socket joint, the saddle joint, the joint, the condyloid joint, the pivot joint, and the gliding joint are the six different types of freely movable joints.

Ankle, knee, and elbow joints are all examples of joints, which are a type of synovial joint. These are formed when two or more bones are allowed to move along only one axis in order to move . The bones that make up joints are able to move in order to reduce the angle that is formed between them.

Thus , knee and elbow joints are different.

Walking is a basic locomotor movement. Is walking on a treadmill a locomotor movement? Defend your answer with two reasons.

Answers

Walking on a treadmill would not be considered a Locomotor movement. Locomotor movements take a person from on place to another, when on a treadmill, you don't go anywhere. A locomotor movement also involves moving, forward, backwards, and even upwards, when on a treadmill, you don't actually move in any of these directions.

Which pituitary hormone activates the secretion of cortisol from the adrenal glands?

Answers

I think it is the anterior lobe of the pituitary gland. CRH and vasopressin stimulate the secretion of ACTH.

Final answer:

The hormone released by the pituitary gland that stimulates cortisol production in the adrenal glands is the adrenocorticotropic hormone (ACTH).

Explanation:

The pituitary hormone that activates the secretion of cortisol from the adrenal glands is known as the adrenocorticotropic hormone (ACTH), also referred to as corticotropin. ACTH stimulates the adrenal cortex, which is the outer layer of the adrenal glands, to release cortisol and other corticosteroids. The production of ACTH is initiated by corticotropin-releasing hormone (CRH), which the hypothalamus secretes in response to stress and other factors into the hypophyseal portal circulation.

Once ACTH reaches the adrenal glands, it binds to receptors on the cells in the adrenal cortex, which in turn trigger the synthesis and release of cortisol. Cortisol is a vital hormone involved in the body's stress response, regulation of metabolism, inflammation, and immune response. The entire process is part of the hypothalamic-pituitary-adrenal (HPA) axis, which is a major part of the endocrine system responsible for regulating stress and body homeostasis.

A 2012 report from the U.S. Surgeon General stated: "Another common practice is strategically locating tobacco-related marketing materials where young children will be exposed to them. Tobacco industry executives acknowledge that products and advertising should be placed at eye level (Pollay 2007), but in California, 48% of stores had at least one cigarette marketing item at or below 3 feet from the floor (Feighery et al. 2001)." It was also noted that 25% of cigarette displays were next to candy. In addition, a national study found that about one-third of the stores had tobacco ads at low heights. After California banned counter displays, some stores place cigarettes in transparent displays so product brands could still be seen.

Why did some stores use transparent units to display the cigarettes?

To comply with the new rules while still encouraging cigarette purchases via visual exposure
To ensure children and minors are not exposed to cigarettes and their eye-catching packaging
To minimize exposure to humidity, extending the shelf life of the cigarettes' tobacco
To reduce the occurrence of shoplifting, since cigarettes are high-revenue items

Answers

the answer is C. Suppression of the fight or flight response.

Answer:

A release of stress hormones

Explanation:

In moments of stress, the body releases stress hormones that elevate blood pressure, quicken heartbeat, tighten the muscles, make a person more alert so as to escape that particular strenuous moment.

After the period of stress has passed, the effects of the hormones die down and the chain reactions to the stress are gone. This brief period of release of stress hormone is vital as it is the body's way of trying to fight off stress

Which sport makes you taller?

Answers

Typically Basketball is the main sport that can make you taller, but sports like swimming and cycling are attributes to making you taller as well.

Basketball is a great sport to increase your height naturally.  Playing basketball requires you to run as well as jump.  When you jump up high, your body is no longer fighting the pull of gravity. So your growth plates will gain important extra centimeters in height.  Furthermore, the more you move, the more growth hormones you will produce.  Swimming is another sport that helps you grow taller effectively.  When you swim, all the muscles of your body come in motion, especially, muscles in legs, arms, and chest.  Swimming will help you increase the length of the spine to improve your height.  According to scientists, cycling can stimulate your growth height as well.  If you ride a bike regularly, the joints in the legs will be stretched. This helps you to stimulate the growth and development of height.

D. does not account for one's body frame size or muscle content

Answers

The answer is B. measures the percentage of one's body fat directly.

Hope I helped :)

The statement which is not true about the body mass index is that it measures the percentage of one's body fat directly. Thus, the correct option for this question is B.

What is Body mass index?

Body mass index may be characterized as the weight of an individual in kilograms divided by the square of height in meters. It is an approximate measure of whether someone is overweight or underweight.

The body mass index (BMI) is a measure that significantly utilizes your height and weight in order to work out if your weight is healthy. The BMI calculation divides an adult's weight in kilograms by their height in meters squared.

BMI uses statistical data on weight and height across the population. It depends on the correlation between weight and body fat. It does not account for one's body frame size or muscle content.

Therefore, the statement which is not true about the body mass index is that it measures the percentage of one's body fat directly. Thus, the correct option for this question is B.

Final answer:

Griffin can refuse negative peer pressure by being direct, offering an excuse or reason, using delay tactics, or suggesting alternative activities.

Explanation:

Griffin can handle negative peer pressure to use drugs in several healthy and assertive ways. Here are some refusal strategies that he could use:

Direct refusal: Griffin can simply say "No, thanks" or "I'm not interested in trying that." Being direct shows that he has made a decision and is sticking to it.

Excuse or reason: He can provide a plausible excuse, such as having a health concern, or say that he needs to stay clear-headed for a responsibility like driving or studying.

Delay tactics: Griffin might say he's not feeling well at the moment or is preoccupied with another task, indicating that now is not a good time.

Alternative suggestions: He could suggest an alternative activity that does not involve drugs, like watching a movie or playing a sport.

Using these strategies, Griffin can stay true to his values and avoid succumbing to the pressures of drug use and its associated risks.
