how and why are organisms classified according to shared characteristic
Answer:
All living organisms are classified into groups based on very basic, shared characteristics. Organisms within each group are then further divided into smaller groups. This grouping system makes it easier for scientists to study certain groups of organisms

As sound waves travel through air, they cause air molecules to do what?
Answer:
To vibrate
Explanation:
When sound waves travel, they need to form vibrations so the air molecules vibrate
We run, play, work, study. We need energy to do all of this. In fact, one characteristic of living things is that they need and use energy. Two processes are needed in us humans to break down food to release the energy that is stored in our food. They are ____________ and cellular respiration.
A) circulation
B) digestion
C) excretion
D) photosynthesis
I think digestion would be the answer here. Humans can't do photosynthesis. Excretion is how we expel waste. And circulation is how oxygen gets to our cells.

Why does a larger quantity of water take longer to freeze ?
Answer:
If the water is initially hot, cooled water at the bottom is denser than the hot water at the top, so no convection will occur and the bottom part will start freezing while the top is still warm. This effect, combined with the evaporation effect, may make hot water freeze faster than cold water in some cases.
Explanation:
Answer:
As the quantity of liquid is bigger it will take longer to freeze because more energy will have to be used. There is a state of matter that water has which is called super cooling this is where the water is at a freezing tempture but ice crystals haven't be formed correctly. Different liquids freeze at different temperatures. Water will freeze faster than liquids with salt or sugar in them. Some liquids freeze faster than others because of viscosity, or thickness of the liquid. Thicker liquids will freeze more slowly and some will not freeze at all.

What type of organism really spread and diversified during the Cenozoic?
reptiles
fish
amphibians
mammals
Mammals really spread and diversified during the Cenozoic era. So, the correct option is D.
What was Cenozoic era?The Cenozoic Era is defined as the third of the major eras in Earth's history that began about 66 million years ago and extends to the present. This epoch was the interval of time during which the continents assumed their modern configurations and geographic positions during which the Earth's flora and fauna evolved towards the present.
The Cenozoic Era is called the "Age of the Mammals", while the typical landscapes of North America began to develop during the Cenozoic. Birds and mammals rose to prominence after the extinction of giant reptiles.
Thus, Mammals really spread and diversified during the Cenozoic era. So, the correct option is D.

Explanation:
An ion of aluminum has a charge of 3+. The ion contains 10 electrons. How many protons does a neutral atom of aluminum possess?
Answer:
13 protons
Explanation:
Aluminum, which has a symbol of Al, is an element in group 3 of the periodic table. It has a mass number of 27. Since the number of electrons and protons in a neutral atom are the same, a neutral/uncharged atom of aluminum contains 13 electrons, 13 protons and 14 neutrons. Note: Mass number = no. of protons + no. of electrons.
However, according to this question, an ion of aluminum has a charge of 3+, this means that an atom of aluminum has lost 3 electrons i.e. 13 electrons - 3 electrons = 10 electrons. Hence, aluminum atom with charge +3 will have 10 electrons. This doesn't change the fact that aluminum atom in a neutral state possesses 13 protons.

The phylogenetic tree shown shows the evolutionary relationships among finches
What can be concluded from this diagram?
A. Warbler finches and cactus finches are the most closely related.
B. Tree finches and warbler finches are the least closely related.
C. No finches have a common ancestor.
D. Tree finches and cactus finches have a common ancestor.
The phylogenetic tree shown shows tree finches and cactus finches have a common ancestor. So, the correct option is D.
What is Phylogenetic tree?A branching diagram that depicts the evolutionary relationships between a set of creatures, species, or genes is called a phylogenetic tree, sometimes referred to as an evolutionary tree. On the basis of the similarities and contrasts in their physical or genetic traits, it depicts the evolutionary history of these groups.
We can draw the conclusion that cactus and tree finches are more closely connected to one another than they are to any other finch species on the tree. The diagram does not indicate if tree finches and warbler finches are more or less closely related to one another, or whether cactus finches and warbler finches are.
Therefore, the correct option is D.

Based on the diagrams above, what is the percent change in the amount of runoff in urban areas compared to forested areas?
Answer:
It’s D
Explanation:
450 % change occur in the amount of runoff in urban area as compared to forest area.
Percent change450 % is the percent change in the amount of runoff in urban areas as compared to forested areas. We can see in the diagram that in forest area only 10% is runoff water while some is absorbed by the soil and other evaporated in the air.
While on the other hand, in urban area 55% of water leaves the area through runoff which is 45 % higher than forest area so when we put these values in the formula of percent change we get 450 % so we can conclude that 450 % change occur in the amount of runoff in urban area as compared to forest area.

Use your knowledge of the mechanism of photosynthesis and the data presented in the chart to determine which of the statements is a correct explanation for the students' data.Group of answer choicesCup 2 had the highest rate of photosynthesis because it had the highest ratio of disks floating to wattage of light.Cup 1 had a low rate of photosynthesis because 0.5 grams of baking soda did not provide a sufficient amount of CO2.Cup 3 had the same rate of photosynthesis as Cup 1 because they had the same ratio of disks floating to wattage of light.Cup 4 had the lowest rate of photosynthesis because it had the least CO2.
Answer:
D. Cup 4 had the lowest rate of photosynthesis because it had the least CO2.
Explanation:
Carbondioxide gas is the main reactant for the process of photosynthesis which decides the production of food in the leaves. If plants has high amount of carbondioxide gas and water so in the presence of sunlight it produces more food in the leaves in the form of glucose so we can conclude that the lowest rate of photosynthesis occurs due to presence of least concentration of carbondioxide gas in the cup 4.

How do the sun and moon affect the tides?
Answer:
The Sun causes tides just like the Moon does, although they are somewhat smaller. When the earth, Moon, and Sun line up—which happens at times of full Moon or new Moon—the lunar and solar tides reinforce each other, leading to more extreme tides, called spring tides.

Answer: Your answer is Sexual reproduction
Explanation:
The sperm and eggs produced with sexual reproduction provide genetic diversity because their gene combinations differ from those in the parent organisms. Asexual reproduction is called asexual reproduction because the person splits into two people that have the same genes, as opposed to sexual reproduction.
