Answer:
Natural selection is a adaptation process of evolution.
Explanation:
- As the battles are the most diverse type of insects on the planet they consist of about 400,000 or more species of them on the planet.
- They use camouflaged while others are easily visible and its due to this natural property that they acquired from the environment they can easily blend in with the natural features of the real world.
- Such as the barks or the branches of the tree. Some of them can chemically be camouflaged as well, mostly to avoid predators and keep them away.
ANSWER: Last one.
Explanation: Denitrifying bacteria are the agents of this process. These bacteria use nitrate instead of oxygen when obtaining energy, releasing nitrogen gas to the atmosphere. Please let me know if this helps you!
Forest biome: It gives us medicinal plants, woods for commercial purpose. Forests provides us rubber and fibers that is very important for the industries for making various products. They also contribute to perform ecological functions such as carbon storage, nutrient cycling, water and air purification. It also provides habitat to the wildlife.
Freshwater biome: We use fresh water for drinking water, irrigation, sanitation systems, and in industrial factories. Water used from groundwater, rivers and lakes is regained by rain and snowfall.
Marine biome: It serves huge amount of oxygen into the environment and absorbs the atmospheric carbon dioxide.
As a result of the activity of human there is a significant decrease in the number of trees. The products now used are synthetically made which were made up of natural fibers previously. The water source such as rivers, lakes, and ponds are polluted due to which many water borne diseases are increasing day by day. The accumulation of waste which are found in marine biome are reducing the number of flora present inside marine ecosystem.
Answer:
Use Phosphotransferase system where glucose is not available.
Explanation:
Streptococcus pyogenes uses its phosphotransferase system for the uptake and metabolism of non-glucose carbohydrate sources in the environment where glucose is not available. Streptococcus pyogenes also uses malate which is a dicarboxylic organic acid that is present in large amount in both tissue and in the external environment. This malate is a non-glucose carbohydrate source used by Streptococcus pyogenes for the production of energy.
