Inborn behavioral characteristics such as activity level, emotionality, and sociability are known as:______.

xeze [42]

Inborn behavioral characteristics such as activity level, emotionality, and sociability are known as temperament.

Congenital behaviors are behaviors that are genetically integrated into an organism and can be performed according to clues without prior experience. Reflex behaviors, such as doctor-tested reflexes and sucking reflexes in human infants, are very simple innate behaviors.

Innate behavior is rigorous and predictable. All members of the species carry out actions in the same way. Congenital behavior usually involves basic living functions such as foraging and caring for offspring.

Examples of Inborn behavior include reflexes, taxis and motility, fixed behavior patterns and stereotypes, and circadian rhythms. Reflexes are automatic and rapid responses to stimuli. Common reflexes include knee reflexes, newborn suction reflexes, and cat arches when scratched.

The force of contraction (of the heart) can be changed by:

Dmitry [639]

The correct answer is letter A

Sinoatrial node (SA) or pacemaker or sino-atrial node: special region of the heart, which controls the heart rate. It is located near the junction between the right atrium and the superior vena cava and consists of a cluster of specialized muscle cells. The rhythmic frequency of these muscle fibers is approximately 72 contractions per minute, while the atrial muscle contracts about 60 times per minute and the ventricular muscle, about 20 times per minute. Due to the fact that the sinoatrial node has a faster rhythmic frequency in relation to the other parts of the heart, the impulses originating from it spread to the atria and ventricles, stimulating these areas so quickly, so that the rhythm of the SA node becomes the rhythm of the whole heart; that's why it's called a pacemaker.

sukhopar [10]

Answer:

True.

Explanation:

The daily use of marijuana really increases the possibility of an individual developing psychotic problems in the future.

Long-term use of marijuana can even triple the risk of psychotic outbreaks among its users, especially among those who start using the drug at an early age. In addition, continued use increases the possibilities for consumers to have other psychiatric and affective disorders, such as depression, anxiety and apathy.

Among the possible factors that influence the appearance of psychotic outbreaks are the dose of the drug consumed, age and genetic predisposition. High doses and consumption since the beginning of adolescence are described as the factors that contribute to a higher probability of psychotic attacks in adulthood.

What theory implies that you should allow another firm to perform work activities for your company if that company can do it mor

RUDIKE [14]

Answer:

b.theory of comparative advantage

Explanation:

Comparative advantage theory uses the concept of opportunity cost to measure the efficiency of each firm in producing a good or service. If Company A has a higher opportunity cost than Company B in producing a service, it is best to let Company B perform this service, while A must specialize in another activity. This may apply to companies that have the option of producing components of their final product or outsourcing these components. If the opportunity cost of a third party firm is lower, that firm will be more efficient in producing that component. Then the company can use its time and resources for other activities and purchase the outsourced firm's component. This way, the firm will be allowing another company to do part of the business because that other company is more productive in that particular service.
