Answer:
...
Explanation:
find density of salt solution 585g/500cc = 1.17g/cc
leaves density = 1.25g/cc, stars density = 1.12g/cc
Stars float, leaves sink. since everything is in g/cc, you do not have to worry about the info 1ml=1cc.
density = mass / volume.
density of salt solution = 585g(mass)/500cc(volume)

What patterns in the rock layer fossils helped you identify an extinction?
Answer:
Hope this helps!! :D
Explanation:
Often, the rock layers bookending the mass extinction are noticeably different in their compositions. These changes in the rocks show the effects of environmental disturbances that triggered the mass extinction and sometimes hint at the catastrophic cause of the extinction.

What role does gravity play in the water cycle?
Describe the flow of one molecule of water through the water cycle, beginning in the ocean.
Answer:
A and E.
Explanation:
When water evaporates, it leaves the salt. When rain falls, the salt is diluted. The sun causes the evaporation. The also the sunlight is the energy source, the greatest force propelling the water cycle is gravity. Gravity is the force of attraction between two objects, and Earth’s gravity pulls matter downward, toward its center. It pulls precipitation down from clouds and pulls water downhill. Gravity also moves air and ocean water. Also Water travels in a continuous path through Earth called the water cycle. The journey starts in the Earth's oceans. As the Sun heats the ocean, the water evaporates into a gas. The gas meets cooler air, and the gas changes into droplets of tiny water molecules. This process is called condensation. Little droplets of water fall back down to Earth again as precipitation. The precipitation fills up the rivers and various other things and the cycle begins all over again. Now with this being said, there is much more than just this!
Good luck!
Study the image of Earth’s layers. Cross section of layers of the Earth. Inner core equals 1,216 kilometers; Outer core equals 2,270 kilometers. Mantle equals 2,885 kilometers, and consists of lower and upper mantle. Upper mantle is made up by: Asthenosphere at 660 kilometers, Lithosphere at 100 kilometers, Oceanic crust at 5 kilometers, Continental crust at 30 to 40 kilometers. Which statement correctly compares the thicknesses of Earth’s layers? Earth’s mantle is thinner than its oceanic crust. Earth’s outer core is thicker than its mantle. Earth’s continental crust is thicker than its lithosphere. Earth’s lithosphere is thinner than its asthenosphereStudy the image of Earth’s layers.

How does this evidence help explain why the skin cancer rate is higher in Australia than in Brazil, even though the two countries get the same amount of sunlight?
Answer:
The Ozone layer
Explanation:
Ozone in the atmosphere can absorb ultraviolet light, which stops the light from reaching Earth’s surface, so people absorb less of it. Australia has less ozone than other places, like Brazil, and this is why Australia gets more ultraviolet light.
Terrence measures the amount of water displaced by various objects when they are dropped into a graduated cylinder of water.

“The use of fossil fuels by human’s is heating up the atmosphere” is an example of a law or theory? Explain your answer in at least 3 sentences.
Answer: Theory
It is a theory which is true because it is not a law. A theory by definition is “ a plausible or scientifically acceptable general principle or body of principles offered to explain phenomena.” A law is “a rule defining correct procedure or behaviour in a sport.“ Therefore since this a scientific fact and it is used/ not against the law it is a theory

what is found in the molecule dna?
Answer:
DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code.

Why is it necessary to see a similar pattern of change in fossils from several places in order to conclude that an extinction happened?
One can learn a lot about the history of life on Earth thanks to fossils. They can help us understand the origins of life and humanity, the evolution of the planet and its environment across time, and the once-connected nature of the continents that are now widely separated.
What are fossils ?Any surviving remnants, impression, or evidence of a once-living creature from a previous geological epoch is referred to as a fossil. Examples include fossilized bones, shells, exoskeletons, animal or microbe impressions in stone, amber-preserved artifacts, hair, petrified wood, oil, coal, and DNA traces.
Scientists use the fossil record to seek for patterns that may be used to infer which creatures are related to one another, how groups of organisms evolved through time, and how the Earth's climate affected the kinds of plants and animals that could survive for a very long time.
Thus, a lot about the history of life on Earth thanks to fossils. They can help us understand the origins of life and humanity.

Which set of coefficients would balance the following equation?
Mg + AlCl3 → Al + MgCl2
A. 2Mg + AlCl3 → Al + 2MgCl2
B. 3Mg + 2AlCl3 → 2Al + 3MgCl2
C. Mg + 2AlCl3 → 2Al + MgCl2
D. 3Mg + 4AlCl3 → 4Al + 3MgCl2
The chemical equation which is balanced according to law of conservation of mass is 3 Mg + 2 AlCl₃ → 2 Al + 3 MgCl₂.
What is chemical equation?Chemical equation is a symbolic representation of a chemical reaction which is written in the form of symbols and chemical formulas.The reactants are present on the left hand side while the products are present on the right hand side.
A plus sign is present between reactants and products if they are more than one in any case and an arrow is present pointing towards the product side which indicates the direction of the reaction .There are coefficients present next to the chemical symbols and formulas .
The first chemical equation was put forth by Jean Beguin in 1615.By making use of chemical equations the direction of reaction ,state of reactants and products can be stated. In the chemical equations even the temperature to be maintained and catalyst can be mentioned.
