Answer:
an increase in availability of food
Explanation:
deltas
loess hills
kettle lakes
sand dunes
Answer:
I believe it is loess hills and sand dunes
Answer:Loess Hills and Sand Dunes
Friend me!!!!
Explanation:Loess is made of silt that were wind blown from vertical cliffs.
Sand dunes are basically hills of sand. They form when wind is impeded by a rock and it drops some of the sand as it hits the rock. Slowly the deposited sand builds up to form bigger dunes.
Hills since sand dunes are hills also, this is also considered a formation made by wind deposition.
B) chlorophyll.
C) cytochrome a.
D) cytochrome c.
hail
rain
snow
all of the above
Precipitation includes all forms of atmospheric water vapor that falls under gravity, including hail, rain, and snow.
In meteorology, precipitation refers to any product of the condensation of atmospheric water vapor that falls under gravity. This includes forms such as rain, snow, and hail. So, the answer to your question - Precipitation includes hail, rain, snow, or all of the above - is indeed, all of the above.

B. by decreasing the pressure of a chemical reaction
C. by increasing the concentration of reactants in a reaction
D. by decreasing the activation energy of a reaction
Answer: D) By decreasing the activation energy of a reaction
A catalyst is a substance that speed up the rate of chemical reaction without affecting the product of the reaction. They only affect the rate of reaction not the yield of reaction.
Catalyst provide an alternative reaction pathway that has lower activation energy than that of uncatalysed reaction. It increases the frequency of collision and because of these greater collision which lowers the activation energy of the reaction.
A catalyst works by decreasing the activation energy of a reaction, providing an alternative pathway for the reaction to occur with lower energy barriers. Therefore, the correct answer is option is d.
A catalyst works by D. by decreasing the activation energy of a reaction.
A catalyst is a substance that speeds up a chemical reaction without itself being consumed or permanently changed in the process. It achieves this by providing an alternative reaction pathway with a lower activation energy. The activation energy is the minimum amount of energy required for a reaction to occur.
Here's how it works:
In a chemical reaction, reactant molecules need to overcome an energy barrier, represented by the activation energy, to transform into products.
Catalysts provide an alternative route for the reaction that has a lower activation energy. This lower activation energy pathway is often referred to as the catalyzed pathway.
By reducing the activation energy, the catalyst allows more reactant molecules to possess the required energy to overcome the barrier and react, thus increasing the reaction rate.
Importantly, the catalyst itself remains unchanged at the end of the reaction and can be used repeatedly for other reactions.
In summary, a catalyst facilitates a chemical reaction by lowering the activation energy required for the reaction to proceed, making it easier for reactant molecules to convert into products and increasing the reaction rate.
Therefore, the correct answer is option is d.
