A factory that has not followed pollution control standards has been operating in an area that did not have such a factory before. Plants that used to grow well are not doing well. Fish in a nearby river are dying at a higher rate than usual. Why?
A Pollution from the factory is getting into the rain, which is making the pH levels in the soil and water rise.
B It hasn't rained enough and the plants aren't getting enough water.
C The factory has increased the temperature in the area.
D Pollution from the factory is getting into the rain, which is making the pH levels in the soil and water become lower.
Answer:
D
Explanation:
If the pH levels are becoming low then the water and dirt becomes acidic killing fish and plants

Earthworms, small insects, and microorganisms live in the soil and break down dead plants and animals. What would happen to an ecosystem if this process was compromised?
A.
The population of green plants in the ecosystem would increase.
B.
There would be more energy available to consumers in the ecosystem.
C.
The soil quality of the ecosystem would dramatically improve.
D.
The carrying capacity of the ecosystem would be limited.
Answer: D
Explanation:
Since the Earthworms, small insects, and microorganisms live in the soil and break down dead plants and animals. They end up playing a vital role in the ecosystem, if this were to be compromised nothing good would come form it Disease, competition, predator-prey interaction, resource use and the number of populations in an ecosystem all affect carrying capacity. If Earthworms, small insects, and microorganisms couldn't break down the the dead material and return it to the soil, then surely the carrying capacity would be drastically effected.

True
False
Answer:
true

explain how gas is compressed into liquid in a gas barrel
Explanation:
A gas can be converted into a liquid by increasing the pressure & decreasing temperature. So that the condensation occurs. You must also make the molecules closer so that it is a phase change from a gas to liquid. In liquids, the molecules are very near than that of gases.
What would happen if the distance of a planet from the Sun was doubled?
Answer:
Hey! Here are your answers!
1) The Earth would make a double orbit * in terms of time duration of 365.25 days * meaning there'd be about 730.5 days in a year ( a leap year therefore would be every 2 YEARS )
2) Because SOLAR RADIATION (light and heat) takes about 8 mins to reach Earth, this would be double to 16 mins
3) The planet as a whole would cool down significantly to the extent that life cannot exist!
Explanation:
HOPE THIS HELPS!!
According to Kepler's third law, T2 R3, the cube of the mean distance between the planet and the Sun (R) and the square of the time period (T) are exactly related. As a result, the planet's orbital period lengthens by a factor of two.
How does the distance of a planet from the Sun affect it?The orbital period increases and the gravitational pull decreases with a doubled distance from the sun. Depending on how far away from the Sun a planet is, it will have a different orbital speed.
A planet moves more quickly and experiences a stronger gravitational attraction as it gets nearer to the Sun.
It moves in its orbit more slowly the further it is from the Sun because of the Sun's weaker gravitational attraction.
Therefore, the planet's orbital period lengthens by a factor of two.

What are the differences between parents and offsprings ?
Answer:
Offspring is a person's daughter(s) and or son(s); a person's child. While a parent is one of two persons from whom one is immediately biologically descended; a mother or a father.
Answer:
Parents have offspring
Explanation:
Offspring is the result of sexual or asexual reproduction by parents.
The pattern of natural selection where BOTH of the extreme versions of a trait are more advantageous than the average, so a population evolves in both directions away from the average.
Answer:
Stabilizing Variation.
Explanation:
This is the type of variation that occurs when genetic diversity decreases as the population of organism in a particular population based on a specific trait.
Organisms with varied or specific traits within the population are selected against by the selection pressure, with little chances of reproduction, while organisms in between, ( with least variation of this particular traits) which are within the narrow range, survive to reproduce.Thus, this gives rise to narrow population of these particular organisms,(stabilizing variation) which are therefore naturally selected.
Therefore, the variation of the organisms in this population is kept close to the centre of the same mean value.

When the motion energy of an object changes, there is inevitably some other change in energy at the same time. If
an object is slowing down, where is the energy going? (Check all that apply)
The potential energy could be increasing, like a ball thrown into the air.
The kinetic energy could be lost to friction or airfmsistance.
The ball could be returning to its natural resting state.
Due to the conservation of energy, the kinetic energy must stay the same.
Please help
When the motion energy of an object changes, there is inevitably some other change in energy at the same time. If the object is slowing down, where is the energy going?
1. The potential would increase since when the ball is slowing down, its kinetic energy is being transformed into potential energy and when the ball gets hit or kicked again, it releases the potential energy and it transforms into kinetic energy.
2. The kinetic energy wouldn't exactly be lost to friction or air resistance, it's merely being converted into potential energy when the ball is slowing down due to those factors.
3. The ball returning to its natural resting state is correct since according to Newton's 1st Law in which an object that is at rest or is moving will not change unless there is another force acting upon it. in this case, the ball was kicked and there are other forces acting upon it like friction and air resistance, those factors cause the ball to slow down. Eventually the ball will stop and return to its original resting state.
4. This one is incorrect since kinetic energy is not staying the same as the person or any other force that is exerted on it be increased therefore increasing the kinetic energy.
