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.

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:
Experiment:

Which surface is most likely to create an echo?
a room with hard, flat walls
a room with hard, bumpy walls
a room covered in soft, wavy curtains
a room padded with soft, flat cushions
Answers
A room with hard, flat walls surface is most likely to create an echo. Hence option A is correct.
What is echo?Echo is defined as a recurrence of sound caused by sound waves being reflected off of a wall, mountain, or other obstruction. Bats, dolphins, and fishermen all use echoes to find objects or obstructions. To find an obstruction, they are also utilized in SONAR (Sound navigation and ranging) and RADAR (Radio detection and ranging).
Buildings made of glass, metal, and concrete, the brick and metal interior of a warehouse, marble floors and buildings, or, if the room is designed in such a way that the acoustics produce an echo, plastered and painted interior walls, are examples of man-made materials that are smooth enough to produce an echo.
Thus, a room with hard, flat walls surface is most likely to create an echo. Hence option A is correct.

• Acceleration: change in velocity compared with the time it takes to change
- Average Acceleration: (Final Velocity - Starting Velocity) / Time
• Velocity: expressed in meters per seconds (m/s)
• Time: expressed in seconds (s)
• Acceleration is measured in meters per second per second
- meters per second squared (m/s²)
Picture #2:
• Acceleration is a vector
- magnitude
- direction
• Acceleration: increases and decreases in speed
• Positive Acceleration: increase in speed
- sliding down from a hill
- small velocity -> large velocity
• Negative Acceleration: decrease in speed
- car slowing then
- high velocity -> low velocity
- initial velocity is larger than final velocity
- (v2 - v1) will be negative
- acceleration “a = (v2 - v1) / t” will be negative
• Acceleration and velocity (rate of motion) in the same direction = speed will increase.
• Acceleration and velocity in opposing directions = speed will decrease
Picture #3:
• Acceleration: rate at which velocity changes
• Velocity is a vector: has magnitude & direction
- magnitude or direction changes = the velocity changes
• Object accelerates speed = direction of motion or both magnitude and direction changes
• Acceleration depends on amount of time for the change to take place and how much velocity changes
- Small change in velocity can be a large change in acceleration if the change occurred quickly.
- Large change in velocity can be a small change in acceleration if the change occurred slowly.
- Increasing speed by 5 m/s in 5 seconds is smaller acceleration to increase speed by 5 m/s in 1 second.
Picture #4:
• An object changing the direction of motion experiences acceleration even when not speeding up or slowing down
• An object is always turning.
• Centripetal Acceleration: acceleration in circular mode.

Certain actions and/or their method can affect the environment, such as leaving the sink on while brushing your teeth or not turning off a light when you leave the room. I personally make decisions to prevent my association with Greenhouse gases by turning off lights when I leave a room, using minimal water, recycling, etc.

Explanation:
There are every day decisions that may add carbon dioxide to the environment.
Problems:
Burning of fossils fuels. Example: Using cars as transportation. The average car releases around 4.6 metric tons of carbon dioxide per year.Deforestation. Carbon dioxide is released from dead organisms such as trees. Example: As of 2021, 15 billion trees are lost to deforestation.Solutions:
Instead of taking your car to work or school, carpool with a friend. Riding your bike and taking the bus are also good solutions that help minimize carbon dioxide releases.In spare your time, grab a couple of friends and plant some trees! Even planting just a few trees is a great start to help the planet.Have a great day!
