It’s the release of harmful gases e.g. carbon dioxide into the environment due to human activity, therefore causing a rise in global temperatures, which is climate change. Warmer temperatures negatively impact our environment because it causes a decrease in biodiversity, allows more diseases to spread(most live in warmer temp.) and so on.
Selective logging—the practice of removing one or two trees and leaving the rest intact—is often considered a sustainable alternative to clear-cutting, in which a large swath of forest is cut down, leaving little behind except wood debris and a denuded landscape
Answer:
The correct answer will be- light independent reaction or Calvin cycle
Explanation:
The process of photosynthesis takes place in the two phases: light-dependent and light-independent phase.
The light-dependent phase form NADPH and NADPH which are utilized during the light-independent phase to synthesise glucose molecule.
The light-independent phase occurs in the cytosol or stroma of the chloroplast in dark conditions which help synthesize the glucose molecules. The light-independent reaction is also known as the Calvin cycle which forms the glucose molecules in three steps- carboxylation, reduction and regeneration.
Thus, the Calvin cycle is the correct answer.
The polysaccharide is the compound that is unlike wax, saturated fat, and the phospholipid. An example of a polysaccharide is starch.
Answer:
Fermentation is a chemical reaction that takes place in the cytoplasm and occurs when oxygen is low or absent. Byproducts of fermentation may include lactic acid or ethanol. Fermentation yields less ATP than the electron transport chain.
Explanation:
Fermentation is a chemical reaction that occurs under anaerobic or low-oxygen condition whereby the NADH produced during glycolysis is oxidized to NAD⁺ with the production of lactic acid as well as other products such as ethanol.
Since oxygen is lacking, pyruvate and NADH produced in glycolysis cannot be oxidized. In order to produce energy in the form of ATP for the cells and tissues,the NAD⁺ is regenerated from NADH by the reduction of pyruvate to lactic acid by the enzyme lactate dehydrogenase. In some other organisms such as yeast and microorganisms, pyruvate is converted to ethanol and carbon dioxide.
The net production of ATP in fermentation process is 2 molecules of ATp much lesser than that produced in aerobic respiration.
