If a flood occurs in the natural rubber environment, it will ruin the rubber production process. The flood would damage a huge percentage of rubber trees if there was a large quantity of restriction. This natural rubber is required for the production of synthetic polymers. Without the rubber, there would be a restricted supply and a significant decline in synthetic polymers due to ecological damage caused by the flood.
The classification system will soon need to be replaced with something new.

In an experiment, independent variables are those which are changed or manipulated to find the value of dependent variables. Here number of roses is dependent variable because its number depends on how many aphids are present. So option A is incorrect. Kinds of aphids killed is also dependent variable, because its population depends on how much chemical is sprayed to kill it. So, option C is also incorrect. Kind of rose is irrelevant, because aphids will eat any kind of rose. So the right answer is - <u>Option B, kinds of chemicals used</u>. This is because it will determine the number of aphids left and population of roses.
Answer AND Explanation:
The various organisms that surround and interact with a particular organism constitutes its biotic environment. Salinity is the amount of salts dissolved in a given volume of water. It varies widely in various aquatic habitats. Animals in the pond are affected by the salinity of the water since some organisms survive in marine and freshwater habitats.
The amount of carbon dioxide available which is important for photosynthesis by aquatic plants. In addition, oxygen concentration necessary for respiration by aquatic organisms.
Answer:
blood flow
Explanation:
An aqueous stagnant layer that overlies the apical membrane and the subepithelial blood flow are potential barriers to the absorption of drugs that readily penetrate the absorbing cell of the epithelium. The apical, basal, and basement membranes are potential barriers to the absorption of less permeable drugs.
