Answer:
an investigation on how copper affects aquatic life in the reservoir
Explanation:
It was observed that there were two time periods represented in the sediment by larger levels of copper than is recommended in sediment quality guidelines at the San Carlos Reservoir in Arizona
The next things that will be on their mind is to investigate on how copper affects aquatic life in the reservoir
Answer: The three main rock types are igneous, metamorphic and sedimentary. The three processes that change one rock to another are crystallization, metamorphism, and erosion and sedimentation. Any rock can transform into any other rock by passing through one or more of these processes. This creates the rock cycle.
Explanation: thats the rock cycle.. yw
A. behavioral isolation is when the plant or animal acts a particular way to attract their counterparts, like mating rituals.
geographic isolation is the natural barrier preventing similar species from interacting. for example, Galapagos Islands are the only home of flightless cormorants because the islands are so far from any other land for them to invade.
Temporal isolation is when two of the same or similar species cannot reproduce as a result of mismatched sexual maturity.
B. the isolation of two frog species by mating call is behavioral isolation.
<span>Addition of an enzyme, for example amylase will increase the rate at which the starch is broken down into glucose. Amylase functions by rupturing the disaccharide bonds between glucose molecules releasing these into solution. If iodine had been added as an indicator of the presense of starch, the color will fade from brown to very light in a short time.</span>
Answer: C). biomagnification
Biomagnification is the phenomena in which toxic chemicals released from industrial and agricultural wastes flow into water bodies and contaminate them. These toxic chemicals causes diseases, genetic mutations, birth defects and death in organisms which indirectly or directly take them. These toxic chemicals enters into the food chain and affects mainly the organisms which are at higher trophic levels. They get settle at the bottom of the water body with sediments and organisms feed on these sediments. These toxic chemicals are not digested therefore they are transferred from one trophic level to higher trophic level in an undigested and unchanged form. In the highest trophic level the concentration of these toxic chemicals becomes highest and result in mortality of organisms. This shows magnifying and enlarged destruction of organisms in a food chain hence named biomagnification. It affects endangered species of predators like fishes, aquatic mammals and birds which eat fishes.
