Which of the following occurs when the moon is closest to the Earth?
periapsis
apogee
revolution
ellipse
Answer:
periapsis
Explanation:
Periapsis is the point when the orbiting object comes the closest to the thing it is orbiting around; for example, the moon is at periapsis when it is closest to the Earth.
Moon revolves around the earth in an elliptical pathway. At some point moon approaches earth at its closest point. This point is called perigee. This closest approach is called periapsis.
What is periapsis?Moon is the only satellite of earth. Moon revolves around earth along with rotating about its own axis. Earth have a gravitational pull into moon and this force will be different at different point of orbital revolution.
Moon's orbit is elliptical. The points of farthest approach to earth is called apogee and the closest point is called perigee. Every planet will have an apogee and perigee with sun as for earth and also with their satellites.
The farthest approach of moon from the earth is called apoapsis and the closest approach is called periapsis. Periapsis is also called perilunar, parselene, perilunar etc. Hence, option A is correct.

Describe the cycling of carbon in the carbon cycle as it passes through the living and non-living components of the ecosystem.
Answer: Photosynthesis, Decomposition, Respiration and Combustion
Explanation:
The cycling of carbon in the carbon cycle is released from animals and plants in form of carbon dioxide through respiration or released by decomposition and internalized by a process called photosynthesis in plants.
The carbon cycleIt initiates when a plant dies and gets buried turning into fossil fuel. This fossil fuel is burnt by humans converting most of the carbon into carbon dioxide.
Carbon dioxide is added to the atmosphere by respiration of animals and the plants. Plants again use this carbon dioxide to perform photosynthesis thus quickly adding it to their bodies from where the cycle continues.

Imagine that the climate in your region became extremely arid, and freshwater became a scarce and precious resource. Wasteful uses of water, such as watering lawns and filling swimming pools, would be strictly outlawed, and water from the municipal water supply would cost 100 times what it does now. Discuss how you would adapt to that situation.

One way to adapt to this situation would be by reducing water use to strictly necessary activities and collecting water from alternative sources such as rain.
What would change in this situation?Due to scarcity, in this situation, people could not use water for recreation such as water in pools, and in general water usage is limited.
How to adapt to this situation?Possibilities are restricted in this situation since it is not a good idea to continue using water excessively. Instead, the best is to:

A 100-pound bag of fertilizer is marked 0-15-15. How many pounds of nitrogen,
available phosphate, and potassium are there in the bag?
Fertilizers are the chemical element for improvement of productivity of plants. Here, 0-15-15 shows nitrogen 70 pounds, phosphorous 15 pounds and potassium 15 pounds.
Why to label fertilizer?Labeling of fertilizer is to show the content of major nutrients. They are usually labeled with three numbers i.e., N-P-K label, i.e., Nitrogen-Phosphorous-potassium label , such as, 0-15-15. the first number is the percentage of nitrogen, second is for phosphorus and third is for potassium.
Thus, here as per the marking, the quantity of the nutrients are: nitrogen 70 pounds, phosphorous 15 pounds and potassium 15 pounds.
