what are building blocks of polymers
Answer:
A monomer is a type of molecule that has the ability to chemically bond with other molecules in a long chain; a polymer is a chain of an unspecified number of monomers. Essentially, monomers are the building blocks of polymers, which are more complex type of molecules.

what two methods do scientists use to gather information
Answer:
Observation and Experimentation
People who tend to perceive the elements of their environment as
separate and distinct from one another are called
A Field-independent
B. Augmenters
C. Reducers
D. Field-dependent
Answer:
The correct answer is A.
Explanation:
Field independence is a cognitive style that people can manifest, it consists of the ability to isolate a certain trait that is perceived as relevant, from the context in which it is integrated, that is, field-independent people usually isolate the different parts that make up the objects or stimuli. Field-independent people are characterized by having analytical and organizational capacities, a more abstract and impersonal orientation and being autonomous in their social behavior.

Distinguish the difference between a scientific and non scientific question.
Answer:
A scientific question is one where an investigation can be designed and completed to find out the answer without having to do multiple, entirely different investigations to get there. In a word, a scientific question is testable, but a non scientific question is not.

Answer:
whats the name of the unit
Explanation:
What is the concentration of the CaCl2 (calcium chloride) salt solution if you are given 3.2g of CaCl2 and you add 4ml of water? The units for your answer should be mg/ml.
Answer:
800 mg/ml
Explanation:
Recall that: 1 g = 1000 mg.
Hence
3.2 g of CaCl2 = 3.2 x 1000 = 3200 mg CaCl2
mass concentration of CaCl2 = mass of CaCl2/volume of water
= 3200/4 (mg/ml)
= 800 mg/ml
Therefore, the concentration (in mg/ml) of CaCl salt solution formed by dissolving 3.2g of CaCl2 in 4 ml of water is 800 mg/ml.
The concentration of calcium chloride solution will be 800 mg/ml.
The calculation of the concentration of CaCl₂:Based on the given information,
The mass of CaCl₂ given is 3.2 grams. The volume of water is 4 ml.Now the concentration of CaCl₂ can be determined as,
Concentration = Mass/Volume
Now putting the values we get,
[tex]Conc = \frac{3.2 g}{4 ml} \\Conc = 0.8 g/ml\\Conc = 0.8 g * 1000 mg/ml\\Conc = 800 mg/ml[/tex]
Thus, the concentration of CaCl₂ is 800 mg/ml.

Choose the best description, definition for Uniformitarianism. Please help im failing badly
Answer:
The correct answer is b. The principle of Uniformitarianism is based on the idea that Earth´s physical landscape is the result of processes and forces that have happened uniformly since the earth formed.
Explanation:
Stated by the geologist James Hutton, this principle says basically that all the geological processes that currently occur had also occurred in the past. Based on this principle, many events might be explained, and not only geological events, but also biological events.
The Uniformitarianism or Uniformism principle states that all the processes that have occurred during the whole Earth history, have been uniform (that is why this principle is named Uniformitarianism) and similar to the current processes.
This principle is very important nowadays, but knowing that not all processes are completely uniform, they have been changing heir intensity and rhythm. Besides, there is a very important factor that is not repeatable, living organisms, that have been lineally changing throughout history.

What happens to the other organ systems if one organ system fail? How does this affect homeostasis? 5. What is one body system humans have? What is one body system humans DO NOT have?
Explanation:
No .because virus is molecule.
anti=against
bio=living
organ system is formed from the organs supporting each other process.
because they lost the connection.
immue system.
photosynthesis.
1. No
2. Antibiotics cannot kill viruses because viruses have different structures and replicate in a different way than bacteria.
Antibiotics work by targeting the growth machinery in bacteria (not viruses) to kill or inhibit those particular bacteria.
When you think about it structurally, it makes sense that an antibiotic could not work to kill a virus with a completely different set of replicating “machinery”.
3. An organ is a part of the body that performs a special task to help the organism live while an organ system is a collective group of organs.
4. The breakdown of a particular organ system is not supposed to cause the breakdown of another except it performs a function needed for the other organ system to function.
What was the original source of energy the earth has used?
Answer:
The energy of the sun is the original source of most of the energy found on earth.
I hope this helps you!
Answer:
The energy of the sun is the original source of most of the energy found on earth. We get solar heat energy from the sun, and sunlight can also be used to produce electricity from solar (photo-voltaic) cells. The sun heats the earth's surface and the Earth heats the air above it, causing wind.

true or false ? Cell membranes are selectively permeable, allowing only some materials to cross the cell membrane. This
property allows cells to maintain homeostasis.
Answer:
True
Explanation:
Cell membranes are selectively permeable because of the structure of the phospholipid bilayer.
This bilayer only lets certain things in because it depends on the polarity, size, and type of molecule.
For example, glucose molecules are too large to enter. But, carbon dioxide molecules can go in and out easily because of their small size.
Answer:
This statement is True
“One way that a cell maintains homeostasis is by controlling the movement of substances across the cell membrane. The lipid bilayer is selectively permeable to small, nonpolar substances. Proteins in the cell membrane include cell-surface markers, receptor proteins, enzymes, and transport proteins.”

Yosef is playing with a different kinds of rubber bands. Some are very narrow and some are quite wide. Yosef is curious about the rubber bands and develops the following scientific question: Does the width of a rubber brand affect how easy it is to stretch it?
He decides to develop a hypothesis to test this scientific question. What could Yosef’s hypothesis be?
Answer:
If the width of a rubber band is increased, then it will be more difficult to stretch because more force will be needed to stretch it.
Explanation:
Answer:
If a rubber band is narrow, then it will stretch more because it resists less.
