Think of another science topic you studied earlier. How might considering scale be useful when investigating that topic? How is that similar to and different from how the crosscutting concept of Scale is useful in this unit?

Answers

Scale can be extremely important to consider when applying the conclusions of an investigation to a larger group.

Scale is defined as a series of measurements in a given ratio, in order to compare two objects or groups. Some examples include:

Scale modelsScale populations

In the case of scale models, one example may be creating a 1:100 scale model of a building. What this means is that the model created will be one hundred times smaller than the original.

The idea of scale is very important to consider when performing experiments. For example, if we were to take a sample of 10 people and test for a specific bacteria, which gives us a result of 1 in 10 (or 10%) of the people that test positive for the bacteria, it would seem as though it is a very small number of people. However, if we take scale into consideration we can apply this 10% to the global population, which will result in hundreds of millions of people who will test positive for the bacteria.

Scale is important to consider when performing any experiment or drawing conclusions because it offers a method to calculate and make an educated assumption as to the impact of the results on a population that would otherwise be impossible to test.

The chemical formulas are aluminum bromide (AlBr₃), magnesium bromide (MgBr₂), sodium sulfide (Na₂S), and the chemical compound formula of the sodium nitride is Na₃N.

What is the significance of the chemical formulas?

Chemical formulas are important to identify the chemical composition of the mixture as they provide important information about the types and numbers of atoms present in a molecule or compound and also predict the properties of a substance, such as its melting point and boiling point. This is useful in industries such as manufacturing, agriculture, etc which has significant importance in the field of medicine, as it helps researchers understand how the human body interacts with the drug.

Hence, the chemical formulas are aluminum bromide (AlBr₃), magnesium bromide (MgBr₂), sodium sulfide (Na₂S), and the chemical compound formula of the sodium nitride is Na₃N.

True/ False: Substances will diffuse more rapidly through a dense substance. Explain

Answers

Answer:

I'd say true

Explanation:

Mass of the molecules diffusing: Heavier molecules move more slowly; therefore, they diffuse more slowly. The reverse is true for lighter molecules. ... Because cells primarily use diffusion to move materials within the cytoplasm, any increase in the cytoplasm's density will inhibit the movement of the materials.

Answer:

False

Explanation:

As the density of a solvent increases, the rate of diffusion decreases. The molecules slow down because they have a more difficult time getting through the denser medium. If the medium is less dense, diffusion increases.

d. Views could be used to make topographic maps of the area.

Explanation:

Satellite views helps the planners in choosing  a location for the airport because it provides topographic maps of the area which contains all information about natural features of that area such as roads, railways, power transmission lines, contours, elevations, rivers and lakes. So the satellite images provides a great help to the planners to find out suitable place for the airport.

Many aquatic birds secrete waxy organic substances that repel water. The birds use these substances to coat their feathers. An analysis of these substances would reveal that they are composed mostly of…




•Lipids


•Carbohydrates


•Nucleic Acids


•nucleic Acids

Answers

Answer:

The correct answer would be - lipids.

Explanation:

Many aquatic birds secrete a waxy organic substance which coats their feathers and this substance allows their feathers to repel the water which is helpful for their flying even after floating in the water.

An analysis of these substances would tell that these substances are composed of lipids as lipids are the only macromolecules that are hydrophobic which means they try to avoid water and not allow water to pass through them.

________
10. Which arrow or arrows represent reactions that demonstrate a conservation of mass and energy? Explain your answer.
________

Answers

6. Is false because the factory uses mechanical energy and when carbon is released into the atmosphere it is the process of chemical energy.

7. Is true because Solar energy is created when it is used in the process of photosynthesis in a plant. Then chemical energy is used when the plants create glucose.

8. Arrows C + F represent a release of carbon dioxide. Arrow C shows carbon being released into the air from the factory. Arrow F shows respiration and carbon being released.

9. The cycle would be made by process C and E. The process E happen when the organism dies and become a fossil. The organism could be a cow that eats grass(plants) that takes carbon from the atmosphere by doing photosynthesis.
The process in C happens when the factory (nonliving) using fossil fuel and produce carbon. The factory takes the fossil, use it as fuel, and return the carbon to the atmosphere.

10. The process of photosynthesis and cellular respiration can represent the law of conservation of mass and energy. In photosynthesis, you need sunlight(arrow A), carbon dioxide(arrow B) and water. The process will produce glucose which can be used in cellular respiration.
In cellular respiration, the glucose will produce energy which was made from sunlight. It will also produce water and carbon dioxide that will be released back into the atmosphere (arrow F)

Read this passage from chapter 5 of The Prince.There are, for example, the Spartans and the Romans. The Spartans held Athens and Thebes, establishing there an oligarchy: nevertheless they lost them. The Romans, in order to hold Capua, Carthage, and Numantia, dismantled them, and did not lose them. They wished to hold Greece as the Spartans held it, making it free and permitting its laws, and did not succeed. So to hold it they were compelled to dismantle many cities in the country, for in truth there is no safe way to retain them otherwise than by ruining them. And he who becomes master of a city accustomed to freedom and does not destroy it, may expect to be destroyed by it, for in rebellion it has always the watchword of liberty and its ancient privileges as a rallying point, which neither time nor benefits will ever cause it to forget. And whatever you may do or provide against, they never forget that name or their privileges unless they are disunited or dispersed, but at every chance they immediately rally to them, as Pisa after the hundred years she had been held in bondage by the Florentines.What is Machiavellis primary purpose in writing this passage?A. to inform readers about the history of Rome and Sparta and how they built their empiresB. to inform readers about the fates of the cities conquered by the Spartans and the RomansC. to persuade readers that a conquering prince must destroy a former republic if he hopes to hold itD. to persuade readers that a republic will remember freedom and someday rebel against a conqueror If someone could please help me I really need help me with geometry Type the missing number in this sequence:1, 2, 5, 10, , 26, 37, 50 The coordinates of a triangle are P(1, 4), Q(3, 6), and R(5, 2).
