As human populations have changed over the years, people have altered the course of rivers and other waterways to better suit their needs. one approach has been through the damming of certain rivers. over time, many people question whether this effort has been beneficial. what are the negative impacts of damming a river that are being assessed?
dams allow more water to flow into nearby reservoirs, increasing the chances of disease transmission.
dams cause increases in salmon populations because more water is available for them to live in.
dams reduce salmon stocks, which reduces revenue and overall whale populations.
dams allow for invasive species to move around more easily, which reduces biodiversity.
Dams allowing more water to flow into nearby reservoirs thereby increasing the chances of disease transmission is its negative impact and is denoted as option A.
What is a Dam?This is a form of barrier which restricts the flow of water for different reasons such as reservoirs, electricity generation etc.
Since the water flows to reservoirs in close proximity, it increases the risk of disease transmission such as malaria etc.

Water from a small stream on a mountain in North Carolina can affect an estuary that is hundreds of miles away so that pollution can accumulate and damage the estuary from the small stream.
What is an estuary and why is it important?The importance of estuaries is very relevant. Estuaries provide food and habitat to a very wide range of living beings with a decisive role in the marine food chain, where we can highlight several species of fish with commercial value.
With this information, we can conclude that water from a small stream on a mountain in North Carolina can affect an estuary that is hundreds of miles away so that pollution can accumulate and damage the estuary from the small stream.

Based on the hypothesis (Big Bang theory) that the universe is expanding, an analysis of light wave would indicate: A. a decrease in frequency and a red shift.
What is a redshift?A redshift can be defined as a displacement (shift) of the spectral lines of an astronomical (celestial) object toward longer wavelengths and a corresponding decrease in frequency, as a result of the Doppler effect.
Basically, a redshift occur when observing an astronomical (celestial) object from planet Earth because it's receding (moving away) from planet Earth.
In conclusion, we can infer and logically deduce that an analysis of light wave would indicate a decrease in frequency and a red shift based on the hypothesis (Big Bang theory) that the universe is expanding.

Which of the following best describes why in general there are more hares in the ecosystem than foxes.
In 1945 there was a major event that caused the number of hares to dramatically increase. That is why there continues to be more hares than foxes here.
Hares are a lot smaller than the foxes, so more of them can fit into different niches. They can hide better in all of the bushes and behind rocks.
This is because if only 10% of the energy gets passed on to the next trophic level, then you need to have more lower level animals available to support the animals higher up the food chain. The fox must eat several hares to gain enough energy for growth and development
Answer:
C
Explanation:
The reason why there are more hares than foxes in the ecosystem is because if only 10% of the energy gets passed on to the next trophic level, then you need to have more lower level animals available to supports the animals higher up the food chain.

What is aquarium?
An aquarium (plural aquariums or aquaria) is a vivarium, usually contained in a clear-sided container (typically constructed of glass or high-strength plastic) in which water-dwelling plants and animals (usually fish).
According to this question, the aquarium contains water, plants and fish. The glass of the aquarium is transparent and allows the passage of light. Plants are unique set of organisms that have the ability to produce their own food (organic molecule) using the energy from light which they absorb via the Chlorophyll pigment in their Chloroplast. This process carried out by plants is called PHOTOSYNTHESIS.
The amount of carbon in form of carbondioxide (CO2) decreases when the light was switched on in the aquarium due to the process of photosynthesis carried out by the plants.

How does global climate change impact coral growth? (4 points)
Global climate change does not impact coral growth.
Climate change decreases the overall temperature of the ocean, preventing coral growth due to the lack of acidic waters.
Greenhouse gases trap solar radiation, which decreases the temperature of the ocean, causing algae to bloom and prevent coral growth.
Greenhouse gases trap solar radiation, which raises the temperature of the oceans, preventing algae growth that is needed for coral growth.
Climate change impacts coral growth through a rise in the temperature of the oceans which limits the growth of algae.
Climate change and coralsClimate change is brought about by a rise in the global temperature as a result of an increase in the concentration of greenhouse gases. The gases trap reflected solar radiation and cause an increase in the temperature of the globe.
An increase in the temperature of the globe also causes an increase in the temperature of the various oceans of the world. Thus, the growth of algae which are the major components of coral reefs is impacted negatively.
