Plant Cells and Carbon Cycles
Chlorophyll can be found in this part of a plant cell
The chloroplast
This environmentally harmful form of industrial extraction has led to the loss of massive green lands and made it harder for carbon dioxide in the air to be absorbed by trees.
Deforestation
These type of metals are the most reactive on the periodic table and easily form ionic bonds due to weak outer electron shells.
Alkali Metals
In this first stage in the creation of the solar system large clouds of interstellar gas and cosmic dust collapses under the weight of its own gravity.
The Nebular Stage
A surge of water used to spin a turbine that generates electricity represents what type of energy transfer?
Mechanical to Electrical
Carbon dioxide from the atmosphere is absorbed by plants in this form of carbon flux.
Photosynthesis
The last one of these extended periods of global cold weather was approximately 2 billion years ago.
Ice Age
Water (H2O) is an example of this type of molecular bond that share electrons in their outermost shell.
Covalent Bond
Ahmed takes a trip to the moon with a 100kg bag of limes. Once he lands he notices that the gravitational constant on the moon is 1/6 of that on earth. When he lifts the bags of limes should it feel heavier or lighter?
Lighter.
This type of energy is often produced as a form of waster in electrical appliances.
Thermal Energy
This largest of carbon pools is rich with dissolved organic carbon and sediments.
Deep Ocean
Methane and Nitrous Oxide is emitted from an industrial factory contributing to the warming of the atmosphere. What type of gases are these two compounds commonly known as?
Greenhouse Gases
An atom of Calcium has 20 protons, 20 neutrons, and 20 electrons. What is its atomic mass?
40 atomic mass units
An astronaut has a mass of 80 kg. On Jupiter, the gravitational field strength is 24 N/kg.
1920 N
Sound travels fastest through this medium
Solids
This form of carbon flux occurs due to factories burning fossil fuels which emit tons of carbon dioxide into the atmosphere.
Combustion
This was 650 million years ago where planet earth was completely frozen.
Snowball Earth
When you combine a positively charged sodium atom with a negatively charged chlorine atom you produce NaCl (table salt). What type of chemical bond does this represent?
Ionic Bond
On a windy day at the beach Yusuf notices that the tide is unusually high beyond even the normal high tide. What astronomical phenomenon is occurring to explain this surge of water?
Spring Tide.
What property of a table lamp am I measuring if I am calculating the ratio of the useful energy output over the total energy input as a percentage?
Efficiency
This is the rigid outer layer surrounding the plasma membrane in a plant cell. It is made of cellulose and animal cells don't have them.
Cell Wall
This is the result of melting ice caps and glaciers due to increased sea temperatures.
Rising Sea Levels
An atom of Lithium has 3 protons, 4 neutrons, and 3 electrons. What is its atomic number?
3
These miniature planets are formed by pebbles concentrated due to gas drag, collapsing under their own gravity.
Planetesimals
Sound travels slowest through this medium
Air
