I need help with these questions from 8th Grade science, Specifically Chemistry.
Answers should be detailed, 3-4 sentences.
List at least 3 different physical properties or changes of a substance.
List at least 3 different chemical properties or changes that a substance can experience.
EXPLAIN YOUR ANSWER! NO LINKS! PLEASE DON"T ANSWER JUST TO GET POINTS!
I will report your answer if you do any of those things.
Thx in advance!
Answer:
Physical properties of a substance can include color, temperature, and mass. These are physical properties because they can be measured without changing a substance's chemical identity. Chemical properties of a substance can include flammability, acidity, and reactivity. These are chemical properties because they can be measured only by changing a substance's chemical identity.

Answer:
Threatened Species: A threatened species is a species at risk but not yet endangered. California sea otters were classififed as a threatened species. Laws were passed to protect the otters and now they have increased their population size.
Invasive Species: One of the main causes of extinction and endangered species is the introduction of an exotic species. New exotic species are called invasive species. Invasive species can disrupt food chains, carry disease, prey on native species directly, and out-compete native species for limited resources, like food.
Extinction: If a population decreases too much in numbers, they disappear. Extinct species mean that the species has died out and no individuals left. An example of extinction: New Zealand was once home to a bird called the Giant Moa. Humans settled as their population increased the Moa population decreased. The species is now extinct.

What causes changes in ecosystems?
Factors that change the ecosystems are called drivers.
There are direct and indirect drivers.
Direct drivers straightforwardly influence ecosystem process.
Indirect drivers operate more diffusely, By altering one or more direct drivers.
Some direct drivers:
Habitat change Climate change Pollution Invasive speciesOverexploitationSome indirect drivers:
Population change Change in economic activity Sociopolitical factorsCultural factors Technological changesIn the process of precipitation, liquid water changes into water vapor and enters the atmosphere.

Answer:
- The amount of space affects a population's size.
- Available water, food, sunlight and temperature are limiting factors
- Space is also a limiting factor.
- If there are too few resources, populations may migrate to new areas.
Limiting
Factors
- Environmental factors, such as the amount of water, food, sunlight and temperature available, are limiting factors for a population.
- A limiting factor is something that restricts the size of a population. Limiting factors might affect the number of individuals in the ecosystem can support.
Resources affect
populations
Living and nonliving things are both found within the same ecosystem. the living things require the non living things for survival.

The following table shows the distance from the sun of some unknown planets of equal mass.
W 1.5 AU
X 0.723 AU
Which of the following best explains which planet revolves at a faster speed?
A.) Planet X, because the sun pulls it with a greater force.
B.) Planet W, because the sun pulls it with a greater force.
C.) Planet W, because the gravitational force is weakened by distance.
D.) Planet X, because the gravitational force is strengthened by distance.
Answer:
Option D.) Planet X, because the gravitational force is strengthened by distance.
Explanation:
As we know from Kepler's law , the planets that are closer to the sun move at a faster rate in comparison to those planets that are far because of high gravitational force.
According to the question,
both planets have equal mass. Plant W is at 1.5 AU and planet X is at 0.723 AU distance from the sun.
So, planet X revolves at a faster speed because it's shorter distance from the sum as comparison to planet W, strengthened the gravitational field.
Thus, Option D is the correct answer.

Write a paragraph (5-8 complete sentences) using the prompt below:
An ecosystem has many living and nonliving things. Choose one producer, one consumer, and one decomposer. Explain how they work together.
Answer:
The producer is a plant. It produces vegetables and fruits for the consumer to eat. The consumer is an human. It eats the fruits and vegetables that came from the plant. Lastly the decomposer would be for example fungi. It breaks down dead plants and tree trunks. It helps the producer produce and the consumer comsume.
what is the function of tunnels and passageways in subsurface mining?
a. to reach mineral ore deep below the surface of the earth
b. to reach mineral ores on the surface of the earth
c. to drain underground lakes where minerals are found
d. to create strip mines and quarries below the surface of the earth
The function of tunnels and passageways in subsurface mining to drain underground lakes where minerals are found. option C is correct.
What is subsurface mining?Subsurface mining is the process in which mineral ores are too deep to extract at with this mining techniques, subsurface mining methods are used .
An advantage and good thing of subsurface mining is that it will not disturb land than surface mining it only disturbs less than one-tenth the surface amount of land as surface mining and the method.
Therefore, the function of tunnels and passageways in subsurface mining to drain underground lakes where minerals are found. option C is correct.

Explain the flow of energy in the food chain and why stored energy is an important concept of it.
Answer:
"The process of transfer of energy to various trophic level of food chain is known as flow of energy. Energy flow in ecosystem from energy source to autotrophs to heterotrophs."
Explanation:
The energy flow from the primary members, plants to the other level of organism in food chain. Storage of energy is very important because, the stored energy in plants are distributing to all other levels in food chain and utilizing for activities.
What is energy distribution in food chain ?The sun is the main source of energy for practically all ecosystems on earth. Energy moves from one trophic level of the food chain, to the next as primary producers take energy from the sun to make their own food in the form of glucose.
Primary producers are then consumed by primary consumers, who are in turn eaten by secondary consumers, and so on. The sun is the main source of energy for practically all ecosystems on earth.
Energy moves from one trophic level, or level of the food chain, to the next as primary producers take energy from the sun to make their own food in the form of glucose. Only 10% of energy is distributed to the other level and 90% are lost to the surroundings.
