Is there multiple choice answer to the question?
Answer:Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels.
Explanation:
Answer:
, tree rings usually grow wider in warm, wet years and they are thinner in years when it is cold and dry.
Explanation:
Explanation:
Alcoholic Fermentation is a biological fermentation process in the absence of oxygen (- O2), caused by the activity of some microorganisms that process carbohydrates (as a rule, sugars: for example, glucose, fructose, sucrose , that is, any substance that has the empirical form of glucose, that is, a hexose) to obtain as final products: an alcohol in the form of ethanol (whose chemical formula is: CH3-CH2-OH), carbon dioxide ( CO2) in the form of gas and adenosine triphosphate (ATP) molecules consumed by the microorganisms themselves in their anaerobic energy cellular metabolism. The resulting ethanol is used in the production of some alcoholic beverages, such as wine, beer, cider, cava, etc. At present, ethanol has also begun to be synthesized through large-scale industrial fermentation to be Used as a biofuel.
Alcoholic fermentation has the biological purpose of providing anaerobic energy to unicellular microorganisms (yeasts) in the absence of oxygen from glucose. In the process, yeasts obtain energy by dissociating glucose molecules and generate alcohol and CO2 as waste. The yeasts and bacteria that cause this phenomenon are very common microorganisms in fruits and cereals and contribute greatly to the taste of fermented products (see sensory evaluation) One of the main characteristics of these microorganisms is that they live in completely lacking environments of oxygen (O2), especially during the chemical reaction, and that is why alcoholic fermentation is an anaerobic or anaerobic process.
Your answer is correct. Chitin provide the strength to insect exoskeletons. Cellulose is the strength for plant. Starch and glycogen are energy sources for life.
