A. Adaptations
A behavioral adaptation is a change affecting the way an organism naturally acts. This type of adaption could be caused by a change in the surrounding environment or the actions of another species. For example, predatory animals might start hunting in packs -- giving them an evolutionary advantage over solo hunters.
Answer:
Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules or nutrients into adenosine triphosphate (ATP), and then release waste products. The reactions involved in respiration are catabolic reactions, which break large molecules into smaller ones, releasing energy because weak high-energy bonds, in particular in molecular oxygen, are replaced by stronger bonds in the products. Respiration is one of the key ways a cell releases chemical energy to fuel cellular activity. The overall reaction occurs in a series of biochemical steps, some of which are redox reactions. Although cellular respiration is technically a combustion reaction, it clearly does not resemble one when it occurs in a living cell because of the slow, controlled release of energy from the series of reactions.
Saccharides are a former generic name of carbohydrates.Carbohydrates are the fuel of the body: they are our main source of energy.On the other hand, unlike proteins and lipids, they are not essential nutrients, since our body knows how to make them from other nutrients.
<u>ABOUT THE EXERCISE:</u>
-The first proposition is false because: Maltose = glucose + glucose
-The second proposition is correct, Sucrose is also called table sugar (it is the that are used for pastry and bakery
-The third proposition is false because glycogen is a polysaccharide
-The fourth proposition is false too, the correct equation is glucose + galactose yields lactose.
The breakdown of molecules by food enzymes and acid in the stomach
