I would say false
Approximately 80 percent of drugs smuggled into the border are from mexico so that's probably where they get the '80%' from.
Not sure what you mean by dangerous. Charles Darwin had a theory on evolution called Natural Selection. This theory of his essentially states that the organisms that adapt best and most successfully to changes in their surroundings are more likely to survive. A coloration change in beetles would explain this because the color change may help them blend in with their surroundings better, thus escaping predators and having a greater chance of survival. These beetles, due to their success, will become prevalent, meaning that the other beetles will phase out because they have not adapted well to the environment.
From the principle of mass conservation in a chemical process, the total mass of the reactants should be the same as the total mass of the products. So, the best answer here would be the first statement.
This is entirely theoretical as photosynthesis is neither a completely efficient process nor does it take place in an isolated system.
The second statement is incorrect since the products of photosynthesis are glucose and oxygen gas, which are completely different compounds from the water and carbon dioxide reactants.
The third statement is incorrect not only because it contradicts the principle of mass conservation, but because—if anything—mass is lost in the course of an inefficient chemical process like photosynthesis in the form of energy wasted as heat.
The last statement is incorrect for the same reason as the second statement is incorrect; the products are completely different substances from the reactants. For example, one of the products—glucose—can undergo combustion. One of the reactants, water, cannot combust.
Answer:
Biodiversity conservation
Explanation:
<em>Biodiversity conservation means the protection of different species of organisms present around the world due to their potentials to be a source of drug, food, industrial materials or other important human use.</em>
Several important species that could have been a source of food or other important materials have gone extinct either naturally or due to direct/indirect human actions.
Assuming rosy periwinkle has gone extinct, there is no way its extract would have been discovered to be a good treatment for cancer.
<em>Hence, biodiversity conservation or preservation are efforts put in place to preserve organisms that will serve as our future heritage.</em>
