How can using a dam as a source of freshwater also harm wildlife?
A. Dams help control floodwaters.
B. Dams provide drinking water.
C. Dams displace existing habitats.
Ο Ο
D. Dams provide water recreation.
Answer:
c
Explanation:
because its the only one that would be hurting wild life.
Using a dam as a source of freshwater can harm wildlife by displacing existing habitats. Therefore, option (C) is correct.
What are the negative impacts of dams?Dams often require the creation of reservoirs, which can submerge large areas of land and alter the natural flow of rivers and streams. This can lead to the loss of important habitats for fish, mammals, and other wildlife that rely on rivers and streams for food, shelter, and reproduction.
In addition, changes in water temperature, dissolved oxygen levels, and water flow can negatively impact aquatic ecosystems downstream from the dam.
These impacts can be mitigated through careful planning and management, such as the creation of fish ladders and other structures to help fish navigate past the dam, and the release of water at appropriate times to mimic natural flow patterns.

Answer:
Heterogeneous Distribution, ModularityHeterogeneity in statistics means that your populations, samples or results are different. It is the opposite of homogeneity, which means that the population/data/results are the same. ... For example, if everyone in your group varied between 4'3″ and 7'6″ tall, they would be heterogeneous for height.Explanation:
please brainlies me if you carry please #carry on learningIn the diagram of the human digestive system, what organ is labelled 5?
Answer:
The large intestine
Explanation:
The large intestine is a long, tube-like organ connected to both the small intestine and the anus. In an anatomy drawing, it looks almost as if it is wrapped around the small intestine.
As we can see in the drawing, the organ labelled with 5 is wrapped around another organ which is smaller and looks longer. This smaller organ is the small intestine. Since we know that the large intestine wraps around the small intestine, we can infer that the organ is the large intestine.
Hopefully that was helpful! :)
Why do cells become specialized in the human body?
Answer:
They can become any type of cell in the body.
Explanation:
They can transport molecules, metabolize nutrients, and reproduce within this one cell. ... Cell differentiation is the process by which cells become specialized in order to perform different functions. Specialized Cells in the Human Body. Multicellular organisms begin as just one single cell—a fertilized egg.
thinking about the components in pcr, do you think there are major differences in the process of dna replication between species?
The major difference in the process of DNA replication between species is the linear order of nucleotides, which can be amplified by PCR. This technique enables the amplification of specific DNA fragments.
The Polymerase chain reaction (PCR) is a technique widely used in molecular biology in order to amplify and thus identify small DNA fragments (approx. 1000 pb).
The PCR uses all materials required to carry out DNA replication: a thermostable DNA polymerase, primers (DNA oligonucleotides), deoxyribonucleotides (ddA, ddG, ddC, or ddT), and template DNA.
The template DNA indicates the linear order of nucleotides that will be added to the amplified DNA fragment, which is highly specific and may vary even between individuals of the same species.

4 Spheres Observation (Bio, Geo, Atmo, Hydro) : What did you see that represents each? How did they interact with each other? and pls be specific in ur answer, and pls no links!
Answer:
The spheres interact to effect Earth’s systems and processes, and they are constantly changing each other.
For example, ocean currents (hydrosphere) affect air temperature (atmosphere): The Gulf Stream is a powerful water current in the Atlantic Ocean. It’s warm water moderates the temperatures on the east coast of the USA.
Another example of how the spheres affect each other is through erosion. Erosion happens in the desert when wind (atmosphere) shapes the sand in the geosphere. Water (hydrosphere) can also shape land, such as in the formation of the Grand Canyon.
Humans have a huge impact on all spheres. Negative impacts, such as burning fossil fuels, pollute the atmosphere. Piling up our waste in landfills affects the geosphere. Pumping waste into the oceans harms the hydrosphere. And overfishing and habitat destruction can reduce the diversity of living things in the biosphere.
However, people everywhere are working to change things. Recycling efforts are increasing all over the world, and companies are finding new ways to reduce fossil fuels. In the US alone, people are recycling six times more than a generation ago.
