Answer:
<u>Skin:</u> The skin acts as a barrier against external agents that could affect such as microorganisms, changes in temperature, etc.
<u>Excretes waste:</u> The excretion process, is done mainly by lungs (release of carbon dioxide), kidneys (elimination of excess compounds such as nitrogen) and the skin (sweat regulates temperature but also regulates the concentration of salts within the body)
<u>Nails:</u> It protects the soft tissues surrounding the distal phalanx, but it also exerts pressure over on the digits which allows more precission in the movements.
<u>Kidneys:</u> Eliminate waste from the blood and regulate body fluids, by generating urine.
<u>Bladder:</u> In charge of storing the urine produced by the kidneys, for the urination process to be controlled and not so frecuent.
Answer:
White. Although we can't see it, and it may look yellow, or sometimes orange, it is white.
Answer:
Thrombocytes. Thrombocytes (platelets) play an important role in hemostasis, by plugging and repairing damaged blood vessels, thus preventing blood loss. They also participate in a cascade of events that leads to blood clotting by triggering the release of a series of coagulation factors
Answer:
If you are referring to the image below, the answers would be:
Monosaccharides:
- Galactose
- Glucose
- Ribose
- Deoxyribose
- Glyceraldehyde
- Fructose
Disaccharides:
Storage Polysaccharides:
Structural Polysaccharides:
Explanation:
Monosaccharides are simple sugars, typically having 3 to 7 carbons in its structures. Aldoses and ketoses are forms of monosaccharides. If a monosaccharide has a aldehyde, it is an aldose. If a monosaccharide has a ketone, it is a ketose. You also have other forms, depending on te number of carbons. (e.g. Tioses, hexose and pentose)
Disaccharides are two monosaccharides bonded covalently through a glcosidc bond. They form through a condensation reaction, specifically through dehydration synthesis. Thus, the name "di" saccharides.
Polysaccharides are complex carbohydrates that are made up of many monosaccharides. Their functions are mainly storage and make up the structure of tissues.
Storage polysaccharides are polysaccharides that act as food reserves or energy reserves. They are called storage because they are stored away for later use. Starch is a storage polysaccharide that is found in plants and glycogen on the other hand, is found in animals.
Structural polysaccharides help form the structures of cell walls in plants and skeletons in animals. The most common ones are chitin and cellulose.
