Science EOC

The layer of the atmosphere that contains the most water vapor.

Troposphere

What causes a Tropical storm

Warm water evaporating, rising quickly, and interacting with cold air.

What type of weather happens when barometric pressure falls?

Stormy or rainy weather.

What causes convection currents

Caused by warm air rising and cold air sinking.

Why are scientists concerned by ozone depletion?

It would allow UV rays to reach the Earth's surface.

How are air molecules different in troposphere vs thermosphere

Closer in troposphere, farther apart in thermosphere.

Why do most thunderstorms occur in summer?

Combo of warm, moist air and unstable atmospheric conditions.

What weather exists when cirrus clouds are present?

Calm weather

What 3 gases make most of Earth's atmosphere?

Nitrogen, oxygen, and argon

How are Euglena and Volvox different?

Euglena is an individual cell, Volvox is in a colony.

Nucleus function

Acts as the control center of the cell.

Why is muscle considered a tissue?

Group of cells working together to perform a specific function.

How do respiratory and circulatory systems work together

Respiratory takes in oxygen, circulatory delivers it.

Volvox and amoeba food intake

Volvox through photosynthesis, amoeba surrounds its food.

What is the fundamental unit or structure of all living organisms.

Cell

How do digestive and circulatory systems work together?

Digestive breaks down food, circulatory transports it.

How is gamete cell different from all others?

Has half the number of chromosomes compared to other cells.

If person X and Y smoked the same number of cigarettes for twenty years, why did only one develop severe health problems?

Some people have a specific genetic makeup that has a higher tolerance. 

How do amoebas reproduce?

Asexual

How do you determine if the vehicle you are sitting in is moving?

Compare your position to a fixed object.

Where is the kinetic energy of a marble on a rollercoaster the greatest?

At the bottom of a loop or slope where marble is moving the fastest

What does increase in potential energy lead to?

Leads to an increase in mechanical energy.

When you enter a room and turn a light switch…a lamp turns on because?

The circuit is open. Turn it off and the circuit is closed. 

What is the simple machine for moving objects over a flat surface.

Cart with wheels

How does the mechanical energy of a falling rock change?

Transforms into kinetic energy as it falls.

How does a wind turbine produce electricity?

Converts wind's kinetic energy to mechanical energy.

As a ball is dropped, its potential energy will decrease and kinetic energy increases when?

Potential energy decreases, kinetic energy increases the closer it gets to the floor
