1) Would a person's weight on Earth be the same as it would be on the moon? Explain using the key words weight, mass & gravity.
Answers
Answer:
The force gravity exerts on a person determines the person's weight. Even though your mass would be the same on Earth and the moon, if you weigh 132 pounds (60 kilograms) on Earth, you would weigh about 22 pounds (10 kilograms) on the moon.

Buffalo, New York is a city located near a large lake called Lake Erie. Buffalo receives an average of nearly 94 inches of snowfall a year. Using your knowledge of temperature and what you have read, explain why Buffalo receives so much snow.
Answers
Answer: it is further away from the equator
Explanation:
The simple answer to why Buffalo receives so much snow, and why it is is often confined to a specific area, is lake effect snow. Lake effect snow occurs most frequently during cold snaps in early winter. It happens when the transfer of heat and moisture from the warm waters of the Great Lakes to the cold air creates a shallow layer of atmospheric instability, causing air to rise quickly. As the moisture rises and condenses, it begins to fall as snow–and often, a lot of snow. Depending on which direction the winds are blowing, areas in the snow belts near the Great Lakes (including Buffalo) can see several feet of snow in just a few days. According to the National Weather Service, in the Buffalo area, when cold air from Canada moves over the still unfrozen, relatively warm Great Lakes, the lake moisture and instability from this temperature contrast build one or more bands of snow. These bands are then deposited over locations downwind from the lakes, with some areas receiving much more snow than others, depending on their location and the wind direction.

Which interaction occurs when light goes into an object as heat energy?
Answers
Answer:
Absorption. Absorption occurs when photons from incident light hit atoms and molecules and cause them to vibrate. The more an object's molecules move and vibrate, the hotter it becomes. This heat is then emitted from the object as thermal energy.

A rock is taken from the Moon back to Earth. Which of the following correctly
describes the changes to its mass and weight?
a. Its mass has no change, and its weight decreases.
b. Its mass has no change, and its weight increases.
c. Its mass decreases, and its weight has no change.
d. Its mass increases, and its weight increases
Answers
The mass of the rock remains unchanged, and its weight increases.
What is Weight ?
Weight is the force exerted by the earth on an object at the surface of the earth. Mathematically -
W = m x g
where -
m is the mass of object
g is acceleration due to gravity
Given is a rock is taken from the Moon back to Earth.
Mass and weight are completely different from each other. Mass is the amount of matter present inside the body whereas weight is the force exerted by earth on any object on its surface. Mathematically -
W = mass x acceleration due to gravity
W = Mg
The ratio of Weight to mass is [g] (9.8).
W/M = g
Mass of a body remains constant throughout the universe but its weight depends upon the value of acceleration due to gravity of the environment of the planet or any other celestial body in which it exists. Hence, because of this only, the mass of rock remains same but its weight increases as it is brought back to earth since the acceleration due to gravity on earth is greater than that on moon.
Therefore, the mass of the rock remains unchanged, and its weight increases.

Answers
Answer:
The two types of cell are:
-Eukaryotic cell
-prokaryotic cell
Description:
Eukaryotic cell: These are organisms who have a nucleus enclosed within a nuclear envelop. It does not have a cell wall unlike prokaryotes. It has mitochondria and other cell organelles.
Prokaryotic cell: Organisms with no distinct nucleus and other major cell organelles.
We humans are made up of Eukaryotic cell type as we have membrane bounded nucleus and all the essential major organelles to perform vital body function. Humans have complex organization of cells. Cells have cytoskeleton and organelles surrounded by cytoplasm.
Bacteria are prokaryotic, as they have cell wall made of peptidoglycan, they lack nucleus and membrane bounded organelles. Hence considered to be unicellular life forms.
Similarities between prokaryotes and Eukaryotes:
-Both have cell membrane
-Both have genetic material
- Both have ribosome
-Both have cytoplasm
-Both have vacuole
5. The cell wall is like House because it protects the family members inside as cell wall protects the substance inside the cell.
6. The cell membrane is like airplane because it allows passenger to come in and go out the way cell membrane allows substances to enter and leave.
7.The vacuoles is like a basketball because both acts as storage, basket ball stores air and vacuole store other substance.
8.nucleus
9.Vacuole
10.Cytoplasm
11. Cell wall
12.Chloroplast
13. Nucleus
14.Cheek will have greater number of Mitochondria as great function and more energy required which will be released in form of ATP.
15. Differences:
1.Animal cell do not have cell wall whereas plant cells have cell wall.
2. Animal cells have several small vacuoles whereas plant cells have one large nucleus.
3.Plant cells have chloroplast but Animal cells don not.
16.Plants have single large vacuole as it performs two main function
i)To keep the plant upright
ii)To store water
Large vacuole protect cell from potential harm.
17.In plants chloroplast main function is to synthesis food whereas in humans there is no such need as they get sugar from the food they eat.
18. components of cell theory:
1. All living things are composed of cell.
2.Cells are basic units of structure and function for two living beings.
3.All cells come from pre existing cells.
19. All living things are composed of cell:
