Answer: A. is a measure of energy

Explanation:

Heat is one of the easiest forms of energy that man can detect in your environment because we have the sensation of cold, hot, sweat, drink liquids when we feel hot, see the engine of a car heat up, take a bath of water heated by an electric shower or a boiler, etc.

Heat transfer occurs until the moment bodies reach the same temperature (thermal equilibrium). Heat is the energy transferred between a system and its surroundings because of the differences in temperatures.

Answer:

It's the internal energy of matter.

Explanation:

All matter is made of atoms and molecules. These particles are always in motion, whether it is a slow vibration or a rapid movement. The internal motion of matter is a type of energy called heat. In other words, heat is the kinetic energy of matter.

Define the 3 signals for activation and the 3 outcomes of the complement system.\
sp2606 [1]
* More than 40 proteins and glycoproteins involved in the complement system are synthesized by the liver, macrophages, epithelial cells, they are present in the blood in plasmatic form, membrane, some have an enzymatic activity, regulator or membrane receptorThese are elements of the humoral innate immune response, they fight infections, purify immune complexes and apoptotic bodies.
<span>There are indeed three ways to activate the complement:</span>
Classical pathway: Activated by Immunoglobulins in immune complexes, aggregated Immunoglobulins, DNA, CRP, apoptotic bodies .......it involves nine fractions, starting with C1, then C4, C2, C3, to form a classical C5 convertase, then, activation of C5, C6, C7, C8, C9.

Alternative pathway: activated by polysaccharides (bacterial endotoxin), vascular wall poor in sialic acid, aggregated IgE ...C3b like is the first component in the alternate channel cascade, it will create an amplification loop, and form an alternative C5 convertase.

Lecithin pathway: Activated by mannose, fucose (carbohydrate of microorganisms)The first component is the complex MBL / MASP1 / MASP2: "mannose-binding protein": works according to the same principle as the complex C1 of the classical way (MASP2 cleaves the C4 and the rest of the cascade is equivalent to that of the classical way).

the three ways have the same outcome: A C5 convertase (formed by one of the pathways) cleaves C5 into C5a and C5b: C5b is deposited far from other fractions on the antigenic surface. The fixation of C5b in the cell is followed by that of C6, C7, C8, and C9 (9 molecules of C9): formation of the membrane attack complex (MAC) ==> Death of the cell by osmotic shock

Deer’s Point of View


What would you do if you did not have clean oxygen to breathe?  The air is being polluted because of your factories and car fumes. It’s causing global warming and even negatively affecting the Polar Bears. You need to be aware of the other living organisms and environments. Remember, you can’t turn back time, so don’t wait until many more species are extinct, act now.
