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.
This model suggests that the cell membrane is a dynamic structure, because the proteins and phospholipids move laterally within the lipid bilayer ( so it is more of a fluid than solid)

Answer:
There would be no production of high energy sugars in the plant.
Explanation:
Plants produce their food (autotrophism) in a process unique to them called PHOTOSYNTHESIS. Photosynthesis is the process whereby plants produce energy-storing sugars (glucose) in the presence of light from sun.
This photosynthetic process combines Carbon dioxide (CO2) and water (H2O) as reactants to form sugar (C6H12O6) and oxygen (O2) as products. The equation for photosynthesis is as follows:
6CO2 + 6H2O → C6H12O6 + 6O2
This means that water and carbon dioxide are strictly needed for the process of photosynthesis to occur in plants. Hence, if water or carbon dioxide were not available to plants, there would be no photosynthetic process and ultimately no production of high energy sugars.
Answer and explanation:
The theory of chemical evolution is one of the most important theories for understanding the origin of life.
This theory admits that life is the result of reactions envolving inorganic compounds that have combined and formed some organic molecules, such as amino acids, nitrogenous bases and fatty acids.
The organic molecules were then combining, until the first particles with some type of metabolism appeared.
Answer:
A scientific theory is a well-substantiated idea or hypothesis which is supported by the facts obtained from the repeated experiments and the observation related to the natural phenomenon.
The theories are not permanent rather they change or modified with time, they could be even rejected. The reason for the rejection of old theories or replacement of the old theory with new theories is done as more information is gathered and the new theory which could explain the natural phenomenon more accurately will be accepted.
Since the theory gets modifies and rejected at any given time, therefore, they are always considered current theory which could be changed later when new data is gathered.
