Answer:
[tex]\boxed {\boxed {\sf Choice \ B }}[/tex]
Explanation:
First, let's think about what a greenhouse is. It's a building made of glass that plants grow in. The glass traps heat, so the plants can continue to grow, even in the cold and harsh winter months.
The Greenhouse Effect is like that, but on a much greater scale.: planet Earth! Gas particles, infamously carbon dioxide and methane, trap the heat. The sun heats up our planet during the day and it cools at night. The heat goes back into space, but some is trapped by the gases.
This is why many scientists are concerned about global warming. They worry that burning fossil fuels releases carbon dioxide, which traps heat and warm the planet.
So, based on what we learned about the greenhouse effect, choice B is correct.

Drinking water has two sources. It can come from surface water, such as reservoirs or rivers. Or it can come from groundwater where it either naturally surfaces in a spring or where it must be pumped to the surface from a well. Where does your drinking water come from?
Answers
82% of drinking water supplies in Ireland are sourced from surface water (rivers and lakes) and 18% comes from groundwater - it depends where you live (quick g00gle search should answer you question)
Our drinking water comes from the underground sources like wells, hand pumps, etc.
What are the sources of water?Sources of water are the places from where the water comes to earth for the uses.
In our houses drinking water comes from the underground sources, through the wells, hand pumps, etc. From that source we get natural water for the drinking purposes.
Hence we get water from underground sources.

Answers
Explanation:
need points bye have good day
Answer:
CH4+2O2→CO2+2H2O
Explanation:
Start with the least common atoms and leave things like H and O to the end.
You need to have the same number of methane reactants as carbon dioxide products because there is one carbon in each. I’ll set them both to 1 for now. O see two things with oxygen on the product side so we will have to juggle numbers a bit to figure out those. There is only H in the water so we’ll go there next. One CH4 gives 2 water molecules so we have that done now. At last we can tackle the O atoms. In two waters there are 2 and in the CO2 there are two more so a total of 4 O atoms in the products so we need two O2 molecules in the reactant side.
Hope this is useful.

describe what is happening to rock climbers’ body systems and cells at the small scale.
Answers
Answer:
It is being pressured!
Explanation:
The pressure point changes so people aren't used to that certain pressure
As a rock climber climbs higher, the systems and cells experience a decrease in pressure.
Pressure decreases with height. Hence, the higher you go, the lesser the pressure becomes and this may have obvious implications on the cells and systems of a rock climber.
As air pressure decreases at higher altitude, a rock climber may find it difficult to breathe because of the sudden decrease in air pressure hence the respiratory system is affected.
Prolonged exposure to high altitudes may lead to a decrease in the amount of oxygen in blood causing the heart to pump harder.

What role does gravity play in the water cycle?
Describe the flow of one molecule of water through the water cycle, beginning in the ocean.
Answers
Answer:
A and E.
Explanation:
When water evaporates, it leaves the salt. When rain falls, the salt is diluted. The sun causes the evaporation. The also the sunlight is the energy source, the greatest force propelling the water cycle is gravity. Gravity is the force of attraction between two objects, and Earth’s gravity pulls matter downward, toward its center. It pulls precipitation down from clouds and pulls water downhill. Gravity also moves air and ocean water. Also Water travels in a continuous path through Earth called the water cycle. The journey starts in the Earth's oceans. As the Sun heats the ocean, the water evaporates into a gas. The gas meets cooler air, and the gas changes into droplets of tiny water molecules. This process is called condensation. Little droplets of water fall back down to Earth again as precipitation. The precipitation fills up the rivers and various other things and the cycle begins all over again. Now with this being said, there is much more than just this!

If two people attempt the same maneuver, what determines the amount of force that each is required to exert?
Answers
Answer:
Explanation:
you need to change either the turn of the jump or push off higher or lower from the wall
If the two individuals start at the same position and time, the amount of force exerted by each person is determined by mass of the person.
The amount of force exerted by each person is given by Newton's second law of motion, which states that the force exerted by an object is directly the proportional to the product of mass and acceleration of the object.
F = ma
where;
F is the applied forcem is the mass of the objecta is the acceleration of the objectThus, If the two individuals start at the same position and time, the amount of force exerted by each person is determined by mass of the person.

What happens to the motion of an object if forces acting on the object are equal and balanced?
A. The object begins to move
B. The object begins to slow down
C. The motion of the object does not change
Answers
Answer:
When the forces acting on an object have equal strength and act in opposite directions, they are balanced. These forces cancel out one another, and the motion of the object they are acting on remains unchanged. The object may change its speed (speed up or slow down), or it may change its direction.
So I think its C
You see this is because if the forces were different the object would either speed up or slow down but in this case the forces are equal so the motion of the object does not change.

In an exothermic reaction, chemical energy is converted to _____.
1.thermal
2. mechanical
Answers
Because exothermic is having to do with energy
The chemical reactions are generally of many types. The exothermic and endothermic reactions are important among them. In an exothermic reaction the chemical energy is converted to thermal energy. The correct option is 1.
What is exothermic reaction?The chemical reactions which proceed with the evolution of heat energy are defined as the exothermic reactions. The chemical reactions which proceed with the absorption of heat energy are called endothermic reactions.
In an exothermic reaction, system loses heat to surroundings. Since heat is given out in exothermic reactions, the enthalpy of the products will be less than that of the reactants.
In exothermic reaction, q will be negative and the enthalpy change will be also negative. In this reaction chemical bonds are broken and new bonds are formed. The chemical energy is converted to kinetic energy which is released as heat.
Thus exothermic reaction releases thermal energy.
