What is the difference between the James-Lang theory, and the Cannon-Bard and Schachter-Singer theories?

Biology

GarryVolchara [31]3 years ago

Answer: The Cannon-Bard theory proposes that emotions and arousal occur at the same time. The James-Lange theory proposes the emotion is the result of arousal. Schachter and Singer's two-factor model proposes that arousal and cognition combine to create emotion.

Answer:

The Cannon-Brand Theory argues that we experience physiological arousal and emotion at the same time. The theory gives more attention to the role of thought or outward behavior than did James-Lang. He found that emotion occurs even if the brain was not connected to information about bodily responses, which is similar.

<h2>Koch's postulates </h2>

Explanation:

Koch formulated a set of criteria that could be used to identify the pathogen responsible for a specific disease and these criteria came to be known as Koch’s postulates:

The organism must be regularly associated with the disease and its characteristic lesions

The organism must be isolated from the diseased host and grown in culture

The disease must be reproduced when a pure culture of the organism is introduced into a healthy, susceptible host

The same organism must be re-isolated from the experimentally infected host

In the given hypothesis , Koch's postulates could be used as:

1) identify pathogen associated with disease 2) isolate or purify pathogen 3) test subject gets pathogen 4) same disease/ causes liver disease or not

The endocrine system acts through chemical messengers called- -
3241004551 [841]


The best answer is D.

Hormones are chemical messengers  secreted mostly into blood and also extracellular fluid by specialized tissue of the endocrine system and affect the functioning of other tissues or cells.

Most hormones circulate in blood and come in contact with essentially all cells, but a particular hormone will only affect a limited number of cells, which are termed as target cells to that hormone.

A target cell responds to a particular  hormone because it bears receptors for that hormone.

For example the red blood cells have receptors for the  hormone called insulin which is produced by the pancreas. The red cells are able to take in glucose  when their receptors bind to insulin.

4. Which of the following elements does not want to have eight valence electrons? a. magnesium c. hydrogen b. oxygen d. nitrogen
Cloud [144]

Answer:

Hydrogen.

Explanation:

Hydrogen is the simplest chemical element that exists. The symbol for the chemical element Hydrogen is "H" and it is a colourless, tasteless, odorless, and highly flammable gas.

Hydrogen is a chemical element found in group (1) of the periodic table and as such it has one (1) electrons in its outermost shell. Therefore, Hydrogen has an atomic number of one (1) and a single valence electrons because it has only one proton and one electron in its nucleus.

Based on the octet rule which states that atoms of chemical elements gain, lose or share electrons so as to have eight (8) electrons in their valence shell. Therefore, atoms of chemical elements bond in order to attain the electronic configuration of a noble gas i.e a full valence shell which comprises of eight (8) electrons.

However, the chemical element "Hydrogen" is an exception to the octet rule because it is only able to hold a maximum of two (2) valence electrons in its outermost shell to become full.

<em>Hence, Hydrogen is an element which does not want to have eight valence electrons. </em>
