Temperature can affect density in certain ways. If the temperature decreases, what effect can that have on the density of a substance?
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.

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.
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.

Steffan set up an experiment to test out his theory. He set up a test to compare bees that were exposed to fungicide to a control (bees that were not exposed). What did he find?
There was no effect at all. His prediction was not correct
He could not keep the control population from going to plants sprayed with fungicide, so his experiment did not work
90% of the bees in exposed to fungicide got Colony Collapse disorder
Significantly more bees died who were exposed to the fungicide.

The sun gives off ____energy, which enters the atmosphere. Plants absorb some of the energy
and perform photosynthesis to convert it into____energy in the form of sugars. Plants and the
animals that eat them then turn that energy into a different form of ____
energy, in the form of
ATP. When plants and animals use the energy, it becomes ____ energy
Explanation:
Solar
light
Chemical
Kinetic
The sun gives off HEAT energy. Plants convert it into CHEMICAL energy. Plants and animals turn that energy into a different form of CHEMICAL energy. When plants and animals use energy, it becomes KINETIC energy.
Photosynthesis refers to the chemical reactions by which plants use heat energy from the sun to create chemical energy in the form of chemical bonds of sugars.
Both animals and plants perform a series of metabolic reactions collectively known as cellular respiration.
Cellular respiration refers to the reactions by which plants and animals produce chemical energy in the form of ATP, the energy coin of the cell.
Finally, kinetic energy is the energy associated with motion both in plant and animal cells, which is required to carry out metabolic functions (e.g., reproduction, growth, differentiation, etc).
In conclusion, the sun gives off HEAT energy. Plants convert it into CHEMICAL energy. Plants and animals turn that energy into a different form of CHEMICAL energy. When plants and animals use energy, it becomes KINETIC energy.

(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.
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 ).

Answer:
neptune
Explanation:

Among the gas giants, Neptune has the lowest number of known natural satellites orbiting around it. Neptune has 14 satellites which revolve around it.
What are gas giants?
A gas giant is a giant planet which is composed mainly of hydrogen and helium gases. Gas giants are also known as failed stars because they contain the same basic elements which are present in the stars. Jupiter and Saturn are the gas giants of the Solar System. The gas giants can also be called as giant planets.
The four gas giants in the solar system are Neptune, Uranus, Saturn, and Jupiter. These are also known as the Jovian planets, it refers to the Roman god Jupiter and was intended to indicate that all of these planets were similar to Jupiter god. Among these gas giants. Neptune contains the least number of satellites i.e., 14 orbiting around it.

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.
