Sex refers to physical or physiological differences between males and females, including both primary sex characteristics (the reproductive system) and secondary characteristics such as height and muscularity. Gender is a term that refers to social or cultural distinctions associated with being male or female.

2. Sexual intercourse that sometimes has the outcome of offspring. Most species do it to reproduce and only 2 species in the whole world do it to have pleasure.

In general terms, “sex” refers to the biological differences between males and females, such as the genitalia and genetic differences. “Gender” is more difficult to define, but it can refer to the role of a male or female in society, known as a gender role, or an individual's concept of themselves, or gender identity.

A lung cell maintains homeostasis. Of what is this an example?
hodyreva [135]

The right answer is A: intercellular communication.

An example of intercellular communication is the one between the kidney, liver and lungs to preserve water-soluble homeostasis.

Angiotensinogen, an inactive protein produced by the liver, circulates in the blood. It is the precursor of the active peptides angiotensin I and II, and the only substrate of renin.

In the event of a drop in the pressure in the renal artery, renin (an enzyme sometimes considered as a hormone) is secreted in the kidney by differentiated myoepithelial cells of the arteriole afferent of the juxtaglomerular apparatus. There are also other stimuli promoting renin secretion: decreased natremia in the distal convoluted tubule, ß-agonists, hyperkalemia, PGI2 and stimulation of juxta-glomerular cells by the sympathetic nervous system)

The angiotensinogen is cleaved by the renin and forms a decapeptide called "angiotensin I", inactive.

Angiotensin I will then be converted primarily to angiotensin II by a carboxypeptidase, the angiotensin converting enzyme. This enzyme, secreted by the liver, acts at the pulmonary level.

gogolik [260]

Answer:

The correct answer is : The opponent process theory

Explanation:

The opponent process theory states that one color of the color pair dominant over the other color and suppresses it. German physiologist Ewald Hering proposed it for the first time in late 18th century.

The opponent process theory of color vision suggests that our ability to perceive color is controlled by three receptor complexes with opposing actions. According to this theory the human eye perceive color is regulated by the 3 antagonist or opposing systems or channels in the eye.

For example, when red color hits the specific region of cones it activates the specific bipolar cells but when the cones stroked by the green color the bipolar cells are inhibited due to the members of different color channel or pair.

Thus, the correct answer is : The opponent process theory
