Why are carbon reservoirs important in the carbon cycle?
Answer: Carbon compounds regulate the Earth's temperature, make up the food that sustains us, and provide energy that fuels our global economy. Most of Earth's carbon is stored in rocks and sediments. The rest is located in the ocean, atmosphere, and in living organisms. These are the reservoirs through which carbon cycles.
Carbon compounds govern the Earth's temperature, provide food for us to eat, and provide energy to power our global economy.
What is carbon cycle?The carbon cycle is nature's method of recycling carbon atoms, which travel from the atmosphere into organisms on Earth and then back into the atmosphere.
Carbon is found in carbon dioxide, a greenhouse gas that works to trap heat near the Earth.
It assists Earth in retaining the energy it receives from the Sun, preventing it from escaping back into space. The Earth's ocean would be frozen solid if it weren't for carbon dioxide.
The ocean, geologic reserves of fossil fuels, the terrestrial surface, and the atmosphere are the primary carbon reservoirs. Reservoir sizes are estimated in trillions of kilograms of carbon.
Thus, the carbon reservoirs are important in the carbon cycle.

Engineers use pieces of metal, called heat sinks, to conduct heat away from computer chips so that the chips do not melt. A newly designed computer chip produces too much heat and requires a new type of heat sink to remove the excess heat. What type of heat sink could the engineer build to keep the new chip cool?
Answer:
the engineer should build a water-cooled heatsink
Explanation:
If a regular full metal heatsink is not working due to the computer chip producing too much heat then the engineer should build a water-cooled heatsink. These are usually metal heatsinks that are filled with water. Since water has a great heat capacity it is able to retain heat very efficiently without actually warming up the water (to a certain degree). Therefore, a water heat sink is able to take the heat produced from the CPU and cool down the CPU by dissipating that heat in the water.

Which type of plant life would be present in a climax community but would NOT be present in the early stages of succession?
Grasses
Trees
Wildflowers
Shrubs
A climax community is composed of a wide variety of plant species, among which many of them are trees of varying heights. The correct option is B. Trees.
What is the climax community?
The climax community is the designation used to name communities at their maximum level of stability. It is also the highest level in ecological succession.
These communities have a wide diversity of species and complex trophic nets. However, they do not have extents in the production of organic matter. This is because most of it is consumed by the community. This makes them stable.
Vegetable species composing these communities are usually big-sized, and they characterize by their long life cycle, slow growth, and high survival that make them resist many adverse situations. These species exhibit stratification of canopy cover, existing different levels such as herb plants, shrubs, and trees of varying heights.
Trees are the type of plants that usually compose the climax community but are hardly a component of the early stages.

The extra energy is the minimum amount of extra energy which required by reacting molecule to convert into the product and it is also known as activation energy.
What is activation energy?The extra energy is the minimum amount of extra energy which required by reacting molecule to convert into the product.
Factor at which activation energy depends are as follows:-
1: Activation energy depends upon the nature of reactant if reactant is ionic then required activation energy is less and if reactant is covalent then required activation energy is high.
2: Nature of catalyst if catalyst is positive then required activation energy is less and if catalysts is negative then required energy is high.
3: Activation energy doesn't depend on pressure, temperature, volume etc.
Temperature is one the important factor at which any reaction is depend. In any reaction if temperature is increases the rate of reaction is increases and if temperature is decreases the rate of reaction is decreases.
Here, is the Arrhenius Equation which shows the temperature dependence of the rate of a chemical reaction.
k=Ae^−EaRT
Where,
k= rate constant of the reaction
A= Arrhenius Constant
Ea= Activation Energy for the reaction (in Joules mol^-1)
R= Universal Gas Constant
T= Temperature in absolute scale (in kelvins)
Therefore, The incident that happen before a chemical reaction can begin the activation energy must be reached. The extra energy is the minimum amount of extra energy which required by reacting molecule to convert into the product and it is also known as activation energy.
