<span>The answer is nuclear imaging. A subject is asked to take in a radionuclide (radioactive isotopes) and as the radioactive material passes though the body, it continually emits radiation that is detectable by an instrument such as a gamma camera. Examples of nuclear imaging techniques are SPECT and PET.</span>

Answer:

Magnetic resonance

Explanation:

Images of the brain in action can be obtained by functional magnetic resonance imaging, a method of injecting into the glucose vein labeled with radioactive isotopes, and analyzing through resonance its distribution to different brain areas, while performing functions such as walking, laughing, looking. for figures that arouse compassion, anger, sexual attraction, solidarity. According to this reasoning, magnetic resonance imaging is a technique that allows brain activity to be assessed by measuring radioactive isotopes.

The two systems that work together to cause this reaction are the endocrine system that secretes the hormone and the
Simora [160]

Two control systems of the body

Endocrine and Nervous

Endocrine and nervous system similarities

-Work together to maintain homeostasis

-Release ligands (chemical messengers) that bind to cellular receptors on particular target cells

Endocrine and nervous system differences

Endocrine system: -Transmits hormones through blood

-Targets any cell in the body with the correct receptor

-Very widespread

-Exhibits longer reaction times and has longer-lasting effects

Endocrine System

-Composed of ducts and glands that synthesize and secrete hormones

-Hormones are released into the blood and transported throughout the body

Endocrine system regulation growth and development

-Changes measured from birth to puberty

-Hormones help regulate embryonic cell division and differentiation

-Hormones regulate metabolism

How does the endocrine system maintain homeostasis or blood composition and volume

-Hypothalamus

-Hormones regulate blood solute concentrations (ex glucose ions)

-Hormones regulate blood volume, cellular concentration, and platelet numbers

The endocrine system controlling digestive processes

-Trigger digestion when food is in the stomach

-Hormones influence secretory processes and movement of materials in the digestive tract

Endocrine System controlling Reproductive Activities

-Make sure sperm and egg make it to each other

-Hormones affect the development and function of the reproductive system and the expression of sexual behavior

Endocrine Glands

Contain epithelial tissue that makes and releases hormones within a connective tissue framework

Endocrine Organs

-Glands with solely endocrine functions

-Ex: Pituitary, pineal, thyroid, parathyroid, and adrenal

Endocrine Cells

-Found in clusters in organs with another function

-Examples in Hypothalamus, Thymus, Heart, Stomach, Liver, Pancreas, Small Intestine, Adipose Connective Tissue

-Pancreases is not an endocrine gland, but it does release hormones

Which of these best explains why mitochondria are called the "powerhouses" of the cell?
Sindrei [870]

<em><u>Answer:</u></em>

They generate chemical energy in the form of ATP.

<u><em>Explanation:</em></u>

Mitochondria are the powerhouses of the cell because they "burn" or break the chemical bonds of glucose to release energy to do work in a cell. This releases energy (ATP) for the cell. The more active a cell (such as a muscle cell), the more mitochondria it will have.
