Answer: Free nerve endings

Explanation:

A free nerve ending can be defined as the bare nerve endings that are unspecialized afferent nerve fibers which sends its signal to sensory neuron.

The main function of these nerve endings is to being the signals to the brain from the periphery of the body. They can sense itch, hair movement, temperature, pain et cetera.

The free nerve endings can detect pain, temperature, itch and hair movement. Merkel's disks can detect pressure, position and static touch features. Pacinian corpuscles are sensitive to vibration while Meissner's corpuscles are sensitive to light and touch.

Metabolites are small molecules that:

Pavlova-9 [17]

Answer:

C) generally consist of 1,000 different substances

Explanation:

Metabolites are compounds, usually organic, that participate in the chemical reactions that take place at the cellular level. The set of these biochemical reactions, together with the intracellular physical-chemical processes, constitutes the cellular metabolism, the molecular basis of life. The metabolism includes the degradation of molecules for obtaining energy (catabolism) and the synthesis of molecules necessary for growth, reproduction and repair (anabolism).

The succession of metabolic reactions that transform a given initial substance into another is known as a metabolic pathway. The starting substance is known as a substrate or raw material. The final substance is usually known as the final product or metabolite (a metabolic pathway can generate several final products) and the intermediate substances as intermediate metabolites. An intermediate or final metabolite in one metabolic pathway may be the substrate in another, which makes the vast majority of metabolic pathways interconnected.

Metabolites can be classified into two large groups, primary and secondary. Primary metabolites are defined as those that are directly involved in the normal growth, development and reproduction of an organism with an important physiological function. On the contrary, secondary metabolites are not directly involved in these processes. The absence of a primary metabolite usually leads to immediate or short-term death while the absence of a secondary metabolite does not.

What is not a contribution of the cardiovascular system to other body systems?

Vinvika [58]

OPTIONS:

a) Blood delivers calcium and phosphate ions that are needed for building bone extracellular matrix.

b) Blood carries carbon dioxide to body tissues and removes oxygen for use by other organs.

c) Blood carries newly absorbed nutrients and water to the liver.

d) Blood circulates cells and chemicals that carry out immune functions.

e) Blood delivers clotting factors and WBCs that aid in hemostasis when skin is damaged

Answer:

b) Blood carries carbon dioxide to body tissues and removes oxygen for use by other organs.

Explanation:

Options a, c, d, e are all true statements about the contributions of the cardiovascular system to other body systems except option b which states that “Blood carries carbon dioxide to body tissues and removes oxygen for use by other organs”.

Actually, the cardiovascular system works together with the respiratory system to supply oxygen to body tissues as blood is circulated in the body, while carbon dioxide is removed from the body at the lungs. <em>In order words, carbon dioxide is removed, while oxygen is picked up as blood is transported through the capillaries of the lungs. </em>

An examination of racial classifications from around the world indicates that Group of answer choices the best racial classifica

Vikki [24]

Answer:

the classification of racial types is an arbitrary, culturally specific process.

Explanation:

Racism can be defined as an act, practice or policy by an individual, group of people or institutions which typically involves promoting the ideas and belief that a race is superior in comparison with another. Thus, it simply means the believe that a particular race has dominance over another (an inferior race).

An examination of the classifications of races from around the world indicates that the classification of racial types such as Africans, Americans, Indians, Asians, Black-Americans, Hispanics, etc., is typically based on individual perception, not objective and an impulsive (arbitrary), culturally inclined or specific process.

This ultimately implies that, the classification of racial types is considered not to be based on any form of objective distinction but may be defined by a person's culture.

A culture can be defined as the general way of life of a group of people living together in a particular location or society.

Basically, culture comprises of beliefs, values, behaviors, language, dressing, cuisine, music, symbols, arts, social habits, knowledge, customs, laws pertaining to a particular group of people living together in a society.
