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.

solid water is less dense than liquid waterdiscuss one way this property is important for living organisms:
Answers
Explanation:
When water freezes, water molecules form a crystalline structure maintained by hydrogen bonding. Solid water, or ice, is less dense than liquid water. Ice is less dense than water because the orientation of hydrogen bonds causes molecules to push farther apart, which lowers the density
Solid water, or ice, is less dense than liquid water. Ice is less dense than water because the orientation of hydrogen bonds causes molecules to push farther apart, which lowers the density.
What do you mean by density?Density is the measure of how much “stuff” is in a given amount of space. For example, a block of the heavier element lead (Pb) will be denser than the softer, lighter element gold (Au). A block of Styrofoam is less dense than a brick. It is defined as mass per unit volume.
Density is an important concept because it allows us to determine what substances will float and what substances will sink when placed in a liquid. Generally, substances float so long as their density is less than the density of the liquid they are placed in.
Density is a measure of how much mass there is in a given volume or amount of space. The density of any substance is calculated by dividing the mass of the matter by the volume of the matter.

All of the variables that are kept the same between the experimental
group and control group in an experiment are called
A. independent variables
B. dependent variables
C. experimental variables
D. controlled variables
Answers
Answer:
controlled :variables
An experimental design includes the independent, dependent, and controlled variables. The variables that are kept constant are called controlled variables. Thus, option D is correct.
What are controlled variables?Controlled variables are part of scientific experimentation that are kept constant and remain unchanged through the research and experiment. It is important to control some variables as they might limit and influence the other variables.
They are the same in the experimental group and control group to establish the relationship between the dependent and the independent variables. They are kept at the same rate throughout the groups. For example humidity, temperature, light, etc.
Therefore, in option D. the controlled variables are kept the same in the test and control groups.

As carbon dioxide concentration soar over 400 ppm, what do you expect to see as far as how the earth is responding?
Answers
Answer:
The correct answer would be - increase in green house effect, increase in temperature and rise in sea level are some major response.
Explanation:
Carbon dioxide concentration soar over 400 ppm which means there are 400 particles of carbon dioxide in a million particles of air. It is on the highest level of all time from the beginning. Carbon dioxide is a green house gas which means it is able to absorb heat and trap it in air which leads to increase in temperature of the earth.
Increase in earth temperature will lead to melting of ice lands which result in rise of sea level and cities will drown in sea. Other effect will be pollution in atmosphere and warmer climate and change in pattern of climate. There are many other direct and indirect response in accumulation of carbon dioxide concentration.
Why is the fossil record biased
Answers
Answer:
We don't have every organism that existed identified in the fossil record.
Explanation:
The fossil record is biased because we don't have a complete record of every organism that lived on Earth. It also favors organisms that had structures capable of being preserved.
From Penn Foster
Due to the fact that many early forms of life had soft bodies, the fossil record has gaps, soft creature components do not make good fossils.
What is the fossil record?This indicates that little is known about how these creatures appeared, any fossil remains that may have existed have likely been obliterated by geological processes.
One analysis of the fossil record, which revealed that a staggering 97% of palaeontological data originate from experts in high- and upper-middle-income nations, cautions that our knowledge of the history of life on Earth is biased towards the opinions of wealthier countries.
Therefore, due to geological, physical, chemical, and biological considerations, the fossil record is not only inaccurate, but it also has intrinsic biases.

Paul Snelgrove: A census of the ocean Both in Unit 1 and in Snelgrove’s talk, emphasis is placed on the importance and massiveness of the world’s oceans. Identify some of the facts from both the unit and the video that support this claim. During his talk, Snelgrove comments that we know more about the Moon or Mars than we do about the deep-sea floor and marine habitat as a whole. Why is this surprising and even ironic? Snelgrove describes a fishing disaster that occurred where he grew up in Canada in an effort to explain how we are now experiencing “shifting baselines.” Explain what he means by this term. According to Snelgrove, if you were to suck all of the water out of the ocean, what would you be left with? Describe what Snelgrove discusses in terms of how the oceans play a part in global collaboration. Discuss the concerns Snelgrove has regarding the health and safety of our oceans and ocean life. As he concludes his talk, Snelgrove says, “And as the oceans go, so shall we.” Explain what he means by this statement.

Compare and contrast two of the plazas principales listed above. Consider their location, size, how old they are, the buildings around them, and the events that take place there.
Answers
Hello. You have not shown the plazas to be compared, which makes it impossible to answer that question.
However, I can help you by giving you general guidelines on how to make this comparison.
First of all, you should look at the region around the plazas and assess whether the region has luxurious buildings and high purchasing power, or if it has simple and modest houses, common in middle and lower class communities. This analysis says a lot about the public that frequents these plazas, their location and the events that take place there.
If the plaza is located in a region of more luxurious, unusual buildings and close to tourist spots, it is worth mentioning that this is a plaza frequented by people from higher social classes and that frequents more elitist and restricted events. In addition, these plazas tend to be larger than the others.
If the region, however, has more common and less luxurious buildings, it means that this plaza is in a more accessible place, its audience is middle class people and presents more accessible events, but of general interest to the population and less elitist. In addition, these plazas are usually smaller.
