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

Biology
1 answer:
ziro4ka [17]3 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.

The opossum, which is native to North America, and the kangaroo, which is native to Australia, are marsupials.
timofeeve [1]

Answer:

Belong to the same species

Explanation:

Marsupials carry their young in "pouches", and are therefore related to <em>other</em><em> </em>marsupials, like the <em>kangaroo</em><em>,</em><em> </em><em>opossum</em><em>,</em><em> </em><em>wombats</em><em>,</em><em> </em><em>and</em><em> </em><em>koala</em><em> </em>to name a few.

What are the three main processes that make up aerobic respiration? Name each process, provide a brief description of the proces
IRISSAK [1]

Answer:  

Aerobic respiration is a process glucose produces energy in the presence of oxygen. In this process glucose is oxidized to produce carbon dioxide, water and energy in the form of ATP.

C₆H₁₂O₆ + 6O₂ = 6CO₂ + 6H₂O + Energy (ATP)

Three main processes that make up aerobic respiration are:

1. Glycolysis:  it takes place in the cytosol of the cell. Here, glucose is oxidized to form three carbon molecule pyruvate. This process produces energy in the form of 2 ATP molecules and 2 NADH molecules. These NADH molecules carries 2 energy electrons these electrons are utilized by the electron transport chain.

2. Kreb's cycle: it takes place in the cytoplasm and mitochondria of the cell. Here, the molecules of pyruvate produced during glycolysis is utilized to produce ATP.

3. Electron transport chain:  glucose is not entirely converted into ATP. The NADH molecules produce during glycolysis  produces 2 energy electrons these electrons are taken up by electron transport chain in the mitochondria inner matrix. A proton gradient develops across the matrix after donation of electrons to electron transport chain. This gradient in turn produces energy in the form of ATP.

What variables should the scientists control in the experiment
Drupady [299]

Answer:

It's important for a scientist to try to hold all variables constant except for the independent variable. If a control variable changes during an experiment, it may invalidate the correlation between the dependent and independent variable. When possible, control variables should be identified, measured, and recorded.

Roughly how many more atp’s can be produced via the complete aerobic oxidation of glucose compared to that produced by glycolysi
Lubov Fominskaja [6]

Roughly 15 times more ATP can be produced via the complete aerobic oxidation of glucose compared to that produced by glycolysis alone.

<h3>What is Glycolysis?</h3>
  • The metabolic process known as glycolysis turns the sugar glucose (C6H12O6) into pyruvate (CH3COCO2H). The high-energy molecules adenosine triphosphate (ATP) and reduced nicotinamide adenine dinucleotide are created using the free energy released during this process (NADH).
  • A series of ten enzyme-catalyzed processes make up glycolysis. the binding energy of carbs is captured. One metabolic route that doesn't require oxygen is glycolysis (In anaerobic conditions pyruvate is converted to lactic acid).
  • Glycolysis occurs frequently in various species, which suggests that it is an old metabolic route.
  • In fact, the events that makeup glycolysis and its companion process, the pentose phosphate pathway, take place in the oxygen-free environment of the Archean oceans, likewise in the absence of enzymes, and are catalyzed by metal.
