An object has a mass of 960 g and a volume of 15cm3 what’s the density?
Explanation:
density = mass ÷ volume
mass = 960g
volume = 15³ = 15 × 15 × 15
= 3375 cm
density = 960 ÷ 3375
= 0.28 g/cm³
List the communities in a successional sequence of secondary succession?
The given communities can be ordered in the secondary succession as grass, shrubs, small trees and large tress.
What is secondary succession ?The life cycle of a plant is characterized by secondary ecological succession. Secondary succession, in contrast to primary succession, is a process initiated by an occurrence such as a forest fire, harvesting, hurricane, etc. that reduces an already established ecosystem (such as a forest or a wheat field to a smaller population of species.
As a result, secondary succession occurs on preexisting soil, whereas primary succession typically takes place in a location lacking soil. Many elements, including trophic interaction, starting composition, and competition, might influence secondary succession. Trade-off with colonization
Therefore, the given communities can be ordered from the small level to higher level as grass, shrubs, small trees and large tress.

Answer: Below
Explanation:
Steal wool + oxygen (fire): The steel wool is a grayish color and has a rough surface. Oxygen is transparent It looks like a powder, and like if it was rusted steel wool but then broken apart and turned into a powder Well Iron oxide is 7 grams and steel wool combined is 7 grams so you can say that the mass was conserved Yes, this is a chemical change because the steel wool rusted and rust is a chemical change, so iron oxide is cause because if a physical change.
Egg + Heat : The egg has a yellow yolk in the middle while there is some type of liquid at the border of the yolk, but it is clear, the heat is hot but transparent The egg turned into a delicious food called an omelet what was yolk staid as a liquid but got a tad harder, but the transparent border around it turned white It was conserved because the eggshell was 4 grams and the fried egg is 41 grams It is a chemical change because it results in the formation of new particles, and the chemical bonds break up and new ones are formed.
Water + Heat The water is a clear liquid, while the heat is very hot but transparent The water turned into a type of oxygen -Water Vapor- If 5 g of water becomes a gas it becomes 5 g of water vapor. The mass of the liquid water is simply transferred into the mass of the newly formed water vapor. There was no chemical reaction because the water vapor can be turned back to water also it just changed from a liquid to a gas and did not change its composition
Zinc + Hydrogen Chloride Zinc: a white/silver metallic solid. Hydrogen chloride (dilute hydroelectric acid) a transparent, colorless liquid with a very low pH (acidic). Zinc "dissolved" in hydrogen chloride, while emitting a colorless gas. The liquid remains a colorless liquid, possibly still having a low pH from the unused acid. The colorless gas collected in a test tube gives a popping sound when ignited with a burning wooden splint, so it is not air embedded in the zinc, nor dissolved in hydroelectric acid. Well although the zinc chloride is 12 grams and not 15 the gas that was released was 3 grams and as we all know 3 + 12 is 15 so you could say that the mass was conserved The production of a new substance (most probably hydrogen) from the reaction of the two reactants. When a few drops of the liquid product are evaporated on a watch glass, a white residue is left.
When a few drops of the liquid hydroelectric acid are evaporated on a watch glass, there is no residue. This proves that a new product (hydrogen gas), (white powder, zinc chloride) is produced instead of zinc being physically dissolved in hydroelectric acid.
Sodium Hydroxide + Copper Sulfate Sodium hydroxide is a turbid solution and copper sulfate is in form of bright blue crystals. When their solutions are mixed with each other, a pale blue precipitate of basic copper hydroxide & a solution of neutral salt sodium sulfate will be formed. The sodium hydroxide and the copper sulfate combined make a total of 67 grams and the product is split because the sodium sulfate is 47 grams and the copper hydroxide is 20 grams but all together it is still 67 grams so you could say that the mass was conserved The proof of the reaction is the appearance of pale blue precipitates of basic copper hydroxide & a solution of neutral salt sodium sulfate.

Use each of these terms correctly in your description:
• community
• ecosystem
• biotic
• population
• individual
• abiotic
Answer:
this is an answer for YOU to answer. this is about YOUR ecosystem
Explanation:
just say what it's like, is it a community? is it populated? explain.
Through all the food chain, food web, chemical cycles, etc., biotic and abiotic forces interact within an ecosystem. Therefore, the functional and structural unit of nature is the ecosystem.
What is ecosystem?The functional and structural unit of nature is the ecosystem. This relationship between living and nonliving elements is handled by the ecosystem. All living things, including plants, animals, and microorganisms, rely on non-living substances to survive and keep the natural world in balance.
Individual, population and community play important role in running a ecosystem. Terrestrial Ecology: A terrestrial ecosystem is an ecosystem that is found on land. Grassland, desert, and tundra ecosystems, for instance.
Therefore, the functional and structural unit of nature is the ecosystem.
