Assume that you found an object that looks like a dead twig. You wonder if it might be a stick insect. How could you determine if it is a living thing?
Answer:
I determine if the object is a living thing by checking to see if it responds to the environment
Could determine if it is a living being by checking if it responds to stimuli
Living beings or organisms are all complex structures that are characterized by carrying out activities such as:
feeding.development.reproduction.interaction with other organisms.respond to the environment.Some of the most common classifications of living organisms are:
animals.plants.fungi.According to the above, to know if that object is a living organism the best option would be to activate stimuli in it such as vision, touch, smell, hearing, or taste to see if it has any reaction to these stimuli.
For example, you can touch the object and if it moves it shows a response and therefore it is alive.
According to the above, the correct answer is checking if it responds to stimuli
Why can water pass through the semipermeable membrane, but not salt or sugar?
There’s no answers it’s just space to write but I don’t know what to write can someone please help?
Answer:
no
Explanation:
because water doesn't need to flow through salt and water because it will mix with water
Answer:
due to large size of salt and sugar
Explanation:
Some molecules, such as hydrocarbons and oxygen can cross the membrane. Many large molecules (such as glucose and other sugars) cannot. First, imagine a semipermeable membrane, one that will allow water to pass through but keeps in dissolved molecules

Copy/Make the table of Claim-Evidence- Reasoning found on page xiii, in your digital notebook; Homework section. Then write down your answers.
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.

Why is the fossil record biased
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.

solid water is less dense than liquid waterdiscuss one way this property is important for living organisms:
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.

Answer:Environmental servers build dams to keep water out of areas were animals safe.
Explanation:i just did this one and got it right!
Environmental science helped the trust decide that some dams should be removed dams reduces the complete ecological benefits that can be derived from the free-flowing rivers.
What are Dams?Dams may be defined as a type of barrier that is significantly constructed in order to hold back water and enhance its level that forms a reservoir that is utilized to generate electricity or as a water supply.
Environmental science believed that dams tend to synthesize numerous environmental impacts like alteration in wildlife patterns, destruction of wildlife habituation, interference with the natural flow of water, etc. Dams are also associated with the mechanism of ecological restoration and remarkably interfere with the natural characteristics of water and deteriorate it.
Therefore, environmental science fundamentally supports the trust decide that some dams should be removed.

As carbon dioxide concentration soar over 400 ppm, what do you expect to see as far as how the earth is responding?
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.

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.
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.
Many fishes that inhabit the sub-freezing Arctic and Antarctic waters posses antifreeze proteins; we now know that there are at least five different kinds of antifreeze protein genes that have evolved independently in different species to perform the same function. This is an example of:
Answer:
convergent evolution
Explanation:
This is an example of the term known as convergent evolution. This term refers to the process in which organisms that are not related to one another are still able to independently evolve similar traits. This is all due to both of the species having to adapt to very similar environments thus needing to develop these certain traits in order to survive and pass them on to the next generation in that species line.
