Why is the skin known to be the body's most important nonspecific defense ?

Biology
1 answer:
ziro4ka [17]4 years ago
4 0

Answer:

Explanation:

The body's most important nonspecific defense is the skin, because it acts as a physical barrier to keep pathogens out. Even openings in the skin (such as the mouth and eyes) are protected by saliva, mucus, and tears, which contain an enzyme that breaks down bacterial cell walls.

Describe the properties of the monomers and the type of bonds that connect the monomers in biological macromolecules. Structure
o-na [289]

Answer:

Peptidic bond (proteins), glycosidic bond (carbohydrates) and lipid bond (lipids)

Explanation:

1. Peptidic bond: this type of bond is exclusive for the aminoacids. These monomers create bonds between the carboxylic acid of first and the amino grupo of second (like a acid-base reaction). We have notice, some aminoacids monomers have groups acid or amino into the primary ramification, it groups cannot react to form peptidic bons.

2. Glycosidic bond: principally, this bond is form between the carbon alpha of one monomer (monosaccharide) and one hidroxyle group (-OH) of other monomer. The number of the cabron that has the -OH grupo will bring the name to the bond, for example, "glucose 1-4 fructose". Also, we have a direction of the bond before the firs number, alpha or beta, it depends on the geometry of the monomer.

3. Lipidic bond: usually, it bond type is a coballent and create an anphipathic zone, this is why some lipis are not soluble in water

How is carbon sequestration related to agricultural soil?
svetlana [45]

<u>Answer:</u>

<em>Carbon sequestration in agricultural land is the storage of carbon in the soil. </em>

<u>Explanation:</u>

<em>Carbon sequestration refers to the capture and storage of atmospheric carbon in the soil.</em> Carbon dioxide gas is the common form of atmospheric carbon . Sufficient amount of soil carbon is important for the proper growth of vegetation in the soil.  

<em>Through the process of photosynthesis plants and trees perform biological carbon sequestration.</em> When the number of plants and trees decreases the percentage of soil carbon decreases and percentage of carbon dioxide in the atmosphere increases. <em>Fossil fuels are reserves of carbon in soil. </em>

<em>It is when they are consumed carbon changes to carbon dioxide and reach the atmosphere.</em> When a land is converted to agricultural land the carbon content of the soil reduces.

Replenishing the carbon  content can be done by following several <em>methods like leaving the plant leftovers after harvest in the field itself, use of manure as fertilizer, planting perennial crops etc. </em>
