Carbon Monoxide has 2 atoms total - one atom of carbon (C) and one atom of oxygen (O) chemical formula is CO
Ethylene has 6 atoms total, 2 atoms of carbon (C) and 4 atoms of hydrogen (H), chemical formula is C2H4.
Ethylene has four more atoms than carbon monoxide (6-2) = 4
A barn owl is a bird that feeds on small mammals like rats and mice.
1. The right answer is biological.
The nonspecific response, which constitutes innate immunity, works by not taking into account the type of disease it is fighting. It is the first line of defense against an infection. Several types of mechanisms intervene during this response:
* physical barriers (skin, mucous membranes, tears...)
* inflammation;
* cells of innate immunity:
* complement: it is a group of proteins that plays a role in immunity.
2. The right answer is proteins.
The complement system is a group of 25 known serum proteins, part of the innate immunity. Twelve (12) of these proteins are directly involved in the mechanisms of elimination of pathogens, the others finely regulate the activity of the former to avoid an autoimmune reaction.
3. The right answer is inflammation.
Inflammation is the body's stereotyped immune system reaction to external aggression (infection, trauma, burn, allergy, etc.) or internal (cancerous cells). Inflammation is a universal process, involving all tissues (called ubiquitous); it involves innate immunity as well as adaptive immunity.
Answer: According to the first law of thermodynamics, energy can be transferred from place to place or changed between different forms, but it cannot be created or destroyed. For instance, light bulbs transform electrical energy into light energy, and gas stoves transform chemical energy from natural gas into heat energy.
