Lauren makes an art piece using the densities of various liquids to create layers of colors. She first determines the density of each liquid. Then she pours them into a glass container and watches them separate into layers.
Answers
Answer: you need to divide mass by volume, the honey will sink to the very bottom and the corn oil will float to the top
Explanation:
Lauren needs information like the mass of each substance with respect to its volume in order to estimate the density of each liquid specifically.
What is Density?Density may be defined as a type of physical property that significantly deals with the description of how much space an object or substance takes up with respect to the amount of matter in that object or substance.
In a more simple sense, it is characterized as the measurement of quantity or mass per unit of volume in a particular substance.
According to the question, Lauren calculates the densities of each liquid with the help of the following formula:
Density = Mass/Volume.According to the densities given in the question, the liquid that has a density less than that if water, it will float in water. While the objects or liquids that have a density more than that of water, it will sink to the very bottom.
So, corn oil will float over the surface of the water, while honey will sink to the very bottom.
Therefore, Lauren needs information like the mass of each substance with respect to its volume in order to estimate the density of each liquid specifically.

Answers
(1) Use complete sentences to explain the advantage of using binomial nomenclature in the system of classification. Also explain what kind of information you can get about the organism from its scientific name.
(2) The diagram below shows the branching tree diagram for humans. The text box below it shows the set of derived shared characteristics for the branching tree.
A slanting, horizontal line is shown. On the extreme left, there is a label that says Common Ancestor. Along the slanting, horizontal line there are five dots labeled from left to right as 1, 2, 3, 4, and 5. There is one vertical line between each of the consecutive five dots. The lines are labeled from left to right as Perch, Frog, Pigeon, Rats, and Human. A text box below the branching tree diagram is labeled Derived Shared Characteristics. In the box it says from left to right, Terrestrial during all stages, Jaws, Walking on two legs, Mammary glands and hair, and Four limbs.
Look at the possible derived shared characteristics, shown in the text box. Think about where these should be placed along the branching tree diagram. From the text box, select a shared derived characteristic that frogs and pigeons have. Explain why you think frogs and pigeons share this characteristic.
Answers
Answer:
The advantage of using a binormal nomenclature in the system of classification is it formally names animals of a species of living things by giving a two-part name which either is based on Latin or other languages. One Part is used to classify the genus and the second part of the specific name. An example of this would be ( for humans ).

Temperature can affect density in certain ways. If the temperature decreases, what effect can that have on the density of a substance?
Answers
Liquid water at 25 deg is so rapidly breaking bonds between H2O units and reforming them that extra water molecules get trapped inside the water lattice. This is the reason why liquid water is more dense than solid water.
The bonds in water break more slowly as temperature decreases and the structure tend to trap fewer extra water molecules. At low temperature, more of the water has the same lattice as ice.
Wikipedia, Water Density
It is possible to have liquid water at temperatures well below 0 deg C. Molecules in this supercooled water are free to move. Bonds are made and broken. The long range structure is not perfect but the short range structure of supercooled water is very much like ice. Adding a crystal to supercooled water causes instantaneous ice formation.

Explain homeostasis and why it’s important to the body
Answers
Answer:
Homeostasis regulates your body. When you are too hot, your body produces sweat to cool you down. When you're cold, you muscles shiver to generate warmth. When you have high glucose levels in your blood, your pancreas excretes insulin, and when blood glucose is too low, then it excretes glycogen. Homeostasis basically keeps your body from losing control and it helps you survive.

Answers
Answer:
Explanation:
The cell theory basically just tells you that all living things have more than one cell and that cells are made from other cells. It basically just tells you that cells are our foundation for life, without cells we can't live.
For, example, blood cells. If we didn't have blood cells our body's organs can't get the oxygen and nutrients they need to survive. Without blood cells we could get weak or we could just die instantly.
Hope this helps!!!
The basic tenets of cell theory are that all living things are made up of cells and that cells are the basic units of life. However, cell theory dives deeper than that. ... In other words, everything is made up of cells. Cells are the basic building blocks of organisms and of life.

Availability of waterTemperatureNatural DisasterWhat is Natural Selection?
Natural selection is a set of characters that deal with the most favorable variations that are promoted by nature.
As predators, the height of legs, fur, the color of the body, size of the body, and size of the beak is not related with environmental changes. It can also be said that these characteristics lead to natural selection depending on the conditions, such characteristics are not linked with environmental changes directly.
Therefore, the three examples of environmental changes that can influence natural selection are the availability of water, temperature, and natural disasters.
