Answers

The correct answer is option B, that is, Cannon-Bard theory.

The Cannon-Bard theory of emotion also called the Thalamic theory of emotion. It is a physiological illustration of emotion created by Walter Cannon and Philip Bard. The theory states that one feels emotions and encounter physiological responses like trembling, sweating, and muscle-tension at the same time.

The Cannon-Bard theory suggests that one encounters physiological arousal and emotion at the similar time. The theory offers more attention to the role of outward behavior or thought that than was done by James-Lange.

Vitamin toxicity is more of a concern with which type of vitamins? question 20 options: fat-soluble vitamins because they are stored more readily in body tissues water-soluble vitamins because they are readily absorbed and circulate in the blood water-soluble vitamins because they are the main type found in vitamin supplements fat-soluble vitamins because they are found in higher amounts in foods bvitamins because they are highly abundant in many types of foods

Answers

The correct answer is: fat-soluble vitamins because they are stored more readily in body tissues. Our bodies commonly counteract toxins by storing them in the fat cells. In this way, the harmful toxins are not circulated around the body in the blood stream. The accumulation of vitamins can cause health problems, such as hypervitaminosis which is the ingestion of too much vitamin A, the. symptoms of which are altered bone metabolism and altered metabolism of other fat-soluble vitamins.

The right answer is fat-soluble vitamins because they are stored more readily in body tissues.

Vitamins are substances with a vital role whose needs are met by a

exogenous intake, the body is unable to synthesize them. Diagrammatically, two groups of vitamins are distinguished by their physicochemical, metabolic and functional properties: the fat-soluble vitamins A, D, E and K, and water-soluble B and C.

Excessive intake of fat-soluble vitamins (mainly A and D, which are fat-soluble vitamins) causes hypervitaminosis, which is very toxic to the body.

When training all major muscle groups in a single strength-training workout, a person should complete when training all major muscle groups in a single strength-training workout, a person should complete single-joint exercises before multiple-joint exercises. large-muscle group exercises before small-muscle group exercises. low-intensity exercises before high-intensity exercises. small-muscle group exercises before large-muscle group exercises?

Answers

I think the answer is large muscle group exercises before small group exercises. In most training of muscles, the high intensity exercises are done before low intensity exercises, the small joint exercises before the large joint exercises and finally the large muscle groups before the small muscle groups.

There are times when the intensity of the exercise is done in stages.

Further Explanation

Single-joint (single exercise) is an exercise used to train only one part of the body, such as the biceps, legs, and others. Each set of exercises is focused on 1 or 2 body parts only. If arm training, start from light training such as push-ups, then gradually proceed to the intensity of strenuous exercises such as pull-ups or weight lifting. Remember, the intensity of the exercise must be gradual. This is intended to reduce the risk of muscle injury. If the intensity of the exercise is heavy then every wants to "push to the limit" must be carried out with caution, with more coercion then the muscles will spend a lot of energy and can reduce oxygen levels in the blood that can cause injury or muscle fatigue. If this happens the risk is great and the time to recover is likely to be rather long. All forms of exercise can be done but must understand your own abilities to avoid risks. Even a professional bodybuilder is also still at risk of injury. Therefore, the level of exercise intensity must be considered.

Rest and recovery have an equally important role in boosting the volume and intensity of your exercise program. For that, do not force to train all parts of your body so that muscle and energy are not concentrated. Make a proper training schedule. Remember, to train small body parts but using extreme weights will spend a lot of energy. For that, you need to take adequate rest and adequate nutrition.

Why do we classify lionfish populations near the eastern united states as an invasive species? what suggests that these new populations are not an expansion of the lionfish's natural range? view available hint(s) why do we classify lionfish populations near the eastern united states as an invasive species? what suggests that these new populations are not an expansion of the lionfish's natural range? lionfish are native to the tropical pacific. there are no natural water routes of warm water between the pacific and atlantic oceans. lionfish are native to cold waters near the tip of south america. they could not survive in the warmer waters between their native areas and the colder waters of the east coast of the united states. so, it is very unlikely that these south american populations naturally spread north. lionfish are not good swimmers and have no other mechanisms to spread their populations over great distances. lionfish eat only a few specific types of algae that live in isolated regions of the pacific. if lionfish spread much beyond their native pacific home, they would have nothing to eat?

Answers

The answer is Lionfish are native to the tropical Pacific. There are no natural water routes of warm water between the Pacific and Atlantic oceans.

Invasive species is a species that colonizes an environment in which it is not a native species and tends to upset the natural balance of that environment. Lionfish are naturally found in the indo-pacific, which is their native environment. However, their presence in the eastern United States has have threatened the ecosystem of the region. The fish has decimated fisheries and reef ecosystem since they also don’t have natural predators in the region. Therefore, their population explodes unchecked.

Final answer:

Lionfish populations near the eastern United States are classified as invasive species because they are not native to that region and have been introduced there by human activity.

Explanation:

Lionfish populations near the eastern United States are classified as invasive species because they are not native to that region and have been introduced there by human activity. Several factors suggest that these new populations are not an expansion of the lionfish's natural range. First, lionfish are native to the tropical Pacific and there are no natural water routes of warm water between the Pacific and Atlantic Oceans. Second, lionfish are native to cold waters near the tip of South America, and they could not survive in the warmer waters between their native areas and the colder waters of the East Coast of the United States.

Explain why cellular respiration is more efficient when oxygen is present in cells.

Answers

Oxygen is required for cellular respiration, it is an aerobic process. When no oxygen is present, the anaerobic process(a process that doesn't require oxygen) called fermentation begins creating ATP in smaller amounts. In cellular respiration, Oxygen is used to move electrons through the electron transport chain, and remove excess hydrogen and electrons in the form of water,

Cellular respiration is more efficient when oxygen is present in cells because, in presence of oxygen, a living organism can break down the molecule of glucose into carbon dioxide. This liberates a sufficient amount of energy in order to derive approximately 38 molecules of ATP.

What is Cellular respiration?

Cellular respiration may be defined as a type of biological process which utilizes oxygen in order to break down the foodstuff molecules of glucose for the purpose of the derivation of energy, i.e. required for metabolic activities.

When it comes to the absence of oxygen, a molecule of glucose can convert into pyruvate which gives the energy of only two ATP. This demonstrates the efficiency of oxygen during cellular respiration.

Therefore, the process of cellular respiration is more efficient when oxygen is present in cells.
