Answer:
It wouldn't be able to pump oxygen to your body
Explanation:
One side goes to the lungs to collect oxygen and the other side pumps the oxygen to your body. If there was no chamber the blood would not be able to flow to its proper area and you would die
Most hydroelectric power plants have a dam and a reservoir. These structures may obstruct fish migration and affect their populations. Operating a hydroelectric power plant may also change the water temperature and the river's flow. These changes may harm native plants and animals in the river and on land. Reservoirs may cover people's homes, important natural areas, agricultural land, and archaeological sites. So building dams can require relocating people. Methane, a strong greenhouse gas, may also form in some reservoirs and be emitted to the atmosphere. Reservoir construction is "drying up" in the United States Gosh, hydroelectric power sounds great -- so why don't we use it to produce all of our power? Mainly because you need lots of water and a lot of land where you can build a dam and reservoir, which all takes a LOT of money, time, and construction. In fact, most of the good spots to locate hydro plants have already been taken. In the early part of the century hydroelectric plants supplied a bit less than one-half of the nation's power, but the number is down to about 10 percent today. The trend for the future will probably be to build small-scale hydro plants that can generate electricity for a single community. As this chart shows, the construction of surface reservoirs has slowed considerably in recent years. In the middle of the 20th Century, when urbanization was occurring at a rapid rate, many reservoirs were constructed to serve peoples' rising demand for water and power. Since Hydroelectric energy is produced by the force of falling water. The capacity to produce this energy is dependent on both the available flow and the height from which it falls. Building up behind a high dam, water accumulates potential energy. This is transformed into mechanical energy when the water rushes down the sluice and strikes the rotary blades of turbine. The turbine's rotation spins electromagnets which generate current in stationary coils of wire. Finally, the current is put through a transformer where the voltage is increased for long distance transmission over power lines.

Answer:
What exactly is CER, and how does it work?
CER all starts with a question asked by the teacher. This question is based on a phenomena or lab experience. The student’s explanation or answer, as you may have guessed, will consist of three parts: a claim, the evidence, and the student’s reasoning.
Claim
A claim is a statement that answers the question. It will usually only be one sentence in length. The claim does not include any explanation, reasoning, or evidence so it should not include any transition words such as “because.”
Evidence
The evidence is the data used to support the claim. It can be either quantitative or qualitive depending on the question and/or lab. The evidence could even be a data table the student creates. Students should only use data within their evidence that directly supports the claim.
Reasoning
The reasoning is the explanation of “why and how” the evidence supports the claim. It should include an explanation of the underlying science concept that produced the evidence or data.
Explanation:
The main characteristic that differs the kingdom Fungi from all other kingdoms is the presence of cell wall made of chitin. Kingdom Animalia has no cell wall, while plants, bacteria, and some protists have cell walls but made of different polymers. The members of the kingdom do not photosynthesise and they are heterotrophs, like animals. The kingdom of fungi includes yeast, mold, mildew, and mushrooms and all of those groups are heterotrophs and have chitin cell wall. Yeasts are unicellular fungi, while molds, mildew (which are certain kind of molds), and mushrooms are multicellular fungi,
The answer to this question is "Dendritic Cells". In addition to m cells, the "Dendritic cells" in the epithelium can capture pathogens directly from the lumen of the gut without disturbing other cells and processes in the epithelium of the epithelial layer.
