Question 2 (2 points)
Which of the following best explains why matter must travel through cycles?
a
There is an unlimited amount of matter in the universe, so it can take on any form at
any time.
b
There is a fixed amount of matter in the universe, so it must take on different forms
at different times.
Elements flows within ecosystem in various ways. It is important for matter to travel through cycle as there is a fixed amount of matter in the universe, so needed to be recycled.
What is cycling of matter?Matter cycling is movement of matter from one form to another or from one place to another on the Earth, inside its ecosystems.
Matter is constantly cycling from place to place, and this can have both positive or negative effects. Matter also cycles naturally, or can be due to human activity.
As there are only finite number of nutrients on the Earth, so, it is necessary for them to be recycled in order to ensure the continued existence of living organisms.
Thus, option b is correct.

1)Chad’s family just moved into a new home. The sun went down as Chad was moving boxes into the house, so he had to turn on a light to see. Which statements are true about the power Chad used? Choose the two statements that apply.
A. The power he used to move the boxes can be found by determining the rate at which work was done on the boxes.
B. The power Chad used to move the boxes is the force he used times the distance he moved them.
C. The power of the light Chad turned on is the amount of energy changed from electricity to light.
D. The power of the light Chad turned on is the amount of energy transferred per time.
2)Raul dug a hole in his yard to repair a water pipe. It took him 2 seconds to apply a force of 50 Newtons to push the shovel 0.25 m into the ground. How much power was used?
A. 0.01 watts
B. 6.25 J/s
C. 25.00 N•m•s
D. 100.00 watts
Answer:
1.) A and D
2.) B
Explanation:
The power he used to move the boxes can be found by determining the rate at which work was done on the boxes. The power of light Chad turned on is the amount of energy transferred per time. So the correct options are A and D. In 2nd, the power used was 6.25 J/s. So the correct option is B.
What is power?
The watt, denoted by the letter W, is the common unit used to measure power. James Watt, a Scottish businessman and inventor, is honoured with the unit's name. The watt is certainly a term you frequently encounter in daily life. Electrical devices like light bulbs and stereos commonly advertise their power output in watts. One watt is equivalent to one joule of work performed each second by definition.
Horsepower is another power unit that is still extensively used. This was first used to describe the ability of a regular horse to spin a capstan in the 17th century and is often represented by the sign hp. Since then, a metric horsepower has been defined as the force needed to raise a 75 kg mass a metre in one second, where 75 kg is the mass's weight in kilogrammes.
Therefore, for 1) the correct option is A and D and for 2) the correct option is B.

What is the purpose of greenhouse gases?
Answer:
A greenhouse gas (sometimes abbreviated GHG) is a gas that absorbs and emits radiant energy within the thermal infrared range. Greenhouse gases cause the greenhouse effect[1] on planets. Without greenhouse gases, the average temperature of Earth's surface would be about −18 °C (0 °F),[2] rather than the present average of 15 °C (59 °F).[3][4][5] The atmospheres of Venus, Mars and Titan also contain greenhouse gases.

Answer and explanation:
An ecosystem that is highly resilient is one that has the capacity to resist subjected damage by maintaining its normal patterns of biomass production and the cycling of nutrients. This damage can be anything from fires to deforestation.
A highly resilient ecosystem can be expected to adapt well to change, sometimes permanently, to survive indefinitely. For an ecosystem to be resilient, it has to be flexible and be able to adjust to uncertainty. Highly resilient ecosystems tend to have reproductive cycles, trophic cascades, and population connectivity - all of these characteristics give these ecosystems better chances of surviving different types of disturbances.
