Carbohydrates
Carbohydrates (also called saccharides) are molecular compounds made from just three elements: carbon, hydrogen and oxygen. Monosaccharides (e.g. glucose) and disaccharides (e.g. sucrose) are relatively small molecules. They are often called sugars. Other carbohydrate molecules are very large (polysaccharides such as starch and cellulose).
Carbohydrates are:
<span>1. A source of energy for the body e.g. glucose and a store of energy, e.g. starch in plantsbuilding blocks for polysaccharides (giant carbohydrates), e.g. cellulose in plants and glycogen in the human body components of other molecules eg DNA, RNA, glycolipids, glycoproteins, ATP</span>Monosaccharides
2. Monosaccharides are the simplest carbohydrates and are often called single sugars. They are the building blocks from which all bigger carbohydrates are made.
3. Monosaccharides have the general molecular formula (CH2O)n, where n can be 3, 5 or 6. They can be classified according to the number of carbon atoms in a molecule:
the answer is erosion agent
Answer:
Antibiotic Resistance
Explanation:
Antibiotic Resistance is when bacteria mutates or adapts to become resistant to antibiotics, wether by protecting the bacteria itself or limiting how the antibiotics can effect the body. This antibiotic Resistance can happen from using too many antibiotics, or using antibiotics but not having a high enough dose (so all the bacteria isn't killed). This can cause much more serious infections, like pneumonia and meningitis, to happen, and they can last longer, as they may not immediately respond to treatment. These can also spread to people who don't have a problem with antibiotic Resistance, but will get the antibiotic resistance bacteria which can mess with the other bacteria in their body, making them antibiotic resistant, which turns into a cycle of spreading bacteria and becoming resistant.
Answer:
Explanation:
By inserting human DNA into an animal such as a mouse, medical researchers are provided with important information which may help them in their efforts to conquer human disease.
<u>Human activity</u>. The sixth mass extinction of of organisms caused by human actions potentially could go as far back as the late Pleistocene era (over 12,000 years ago.)
