(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 ).

Between which of the following points would we be able to calculate the displacement of the butterfly? a. A-B b. A-F C.AG
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.

If all of the characteristics of life are required to classify something as “alive”, how can we account for those individuals who are definitely alive, but that do not reproduce (for example, people without children or a sterile mule)?
Answer:
Here is the answer key. Just scroll down to the question and the answer is there.
Explanation:
These organisms are still alive. Reproduction is not important for survival but for the survival of a species.
What is the importance of reproduction?The only way to ensure that the kind of species survives and keeps flourishing on the planet is through reproduction. The process by which organisms give rise to new offspring is called reproduction. It is one of the many defining characteristics of life and loving organisms.
There are some organisms that look and act exactly like their parent/parents. Whereas, other kinds of organisms share similar traits with their parents but are not completely like them. These organisms are unique individuals in their various characteristics.
Some species have two parents, whereas others have just one. It is determined by the method of reproduction by these organisms. It also determines the percent of similarity of the organism with its parents.
Reproduction is basically of two types: asexual reproduction and sexual reproduction. Asexual reproduction involves the development of new organisms by a single parent. Sexual reproduction involves two parents and their fusion of gametes.
Therefore, Reproduction is essential for the survival of a species and not for the survival of an organism.

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.

Kim learns how rocks can change from one type into another over a long period of time. She knows that a rock that undergoes extreme heat and pressure below the surface of Earth can be turned into a metamorphic rock. What processes could cause a metamorphic rock to return to the surface of Earth to be worn down again? Choose the two that apply. A. deposition B. plate movement C. chemical changes D. wind or water erosion
Answer:
i think its a. and d.
Explanation:
Answer:
Option B and Option D
Explanation:
Plate movement responsible for the exposure of the metamorphic rock to the surface of the earth: The collision of the tectonic plate of the earth produces tremendous pressure and heat which initiates the process of regional metamorphism. Due to which huge portions of rock are exposed to such pressure which ends up in the formation of metamorphic rock above the earth's surface. Many mountain ranges with active plate movements are, therefore, metamorphic rocks.Wind and water erosion responsible for pushing metamorphic rock on the earth surface: One of the main reasons for the exposure of metamorphic rock above the surface of the earth is due to weathering and erosion. The top layer of the earth's crust is severely harmed and exposed due to continuous erosion as water takes away loosely bound sand and soil whereas wind sweeps up the sand in desert areas resulting in exposure of rocks on the surface.For more information:
