3,500 calories = 1 pound, so 3,500 would be the answer.
The SA Node is the heart's normal pacemaker. When the SA Node depolarizes, electrical signal spreads through the atrial muscle causing contraction.
Explanation:
Inherent rhythmicity / automaticity - The property of the pacemaker cells of the heart to start electrical sequence of depolarization and repolarization.
SA Node or Sino-atrial Node generates the electrical signal.
The electrical signal passes through internodal pathways, atrial fibres, atrioventricular node (AV Node), the bundle of His, Purkinje fibres, right bundle branch, left bundle branch.
Systole - Contraction of cells when the electrical signal of depolarization reaches the contractile cells.
Diastole - Relaxation of cells when the electrical signal of repolarization reaches the myocardial cells.
Answer:
The option that best identifies the profession illustrated in the following scenario is;
Biologist
Explanation:
A biologist is a professional that study living things, including humans, animals, plants, as well as the environment in which the living things live in such fields as zoology, botany, and ecology
The study of agronomy, which is a sub branch of botany is focused on the science and technology of how plants are made use of for food production, fuel, fibrous material, to restore the land, and for fuel
It is part of the function of the biology profession to study the living things such as genetically modified food and interaction on humans, and also to identify and classify plants and other living organisms, thereby, outlining their differences.
Explanation:
Risk-Taking—Research shows the brain keeps developing well into the twenties, during which time it continues to establish important communication connections and further refines its function. Scientists believe that this lengthy developmental period may help explain some of the behavior which is characteristic of adolescence—such as their propensity to seek out new and potentially dangerous situations. For some teens, thrill-seeking might include experimenting with alcohol. Developmental changes also offer a possible physiological explanation for why teens act so impulsively, often not recognizing that their actions—such as drinking—have consequences.
Answer:
An electromyography
Explanation:
The patient should undergo an electromyography given that this kind of exam is going to be accurate regarding the kind and amount of electrical activity that is occuring in the muscles. This exam can show what is the specific deterioration level that the muscles are going through.
