Answer:
They speed up chemical reactions and are denatured by high temperatures and high pH.
Explanation:
Enzymes speed up chemical reactions. They have specifc conditions that allow them to work effectively. Temperature and pH affects how enzymes work. The optimum temperature is the temperature at which enzymes will function best. In most instances they are around 37-40°C (in the human body). Temperatures above this will denatured (destroy) the enzymes therefore they cannot do their task. At Temperatures below the optimum temperature the enzymes activity is decreased to the point where they may not be active.
Optimum pH is the pH at which the enzymes works best. These vary based on the type of enzyme. Any pH above the optimum will denatured the enzymes (destroy). pH below the optimum will decrease the ezymes activity to the point where they may not be active

Explain the Carbon cycle in 3 paragraphs or more.
Answer:
Carbon cycle is the process where carbon compounds are interchanged among the biosphere, geosphere, pedosphere, hydrosphere, and atmosphere of the earth.
1) Carbon present in the atmosphere is absorbed by plants for photosynthesis.
2) These plants are then consumed by animals and carbon gets bioaccumulated into their bodies.
3) These animals and plants eventually die, and upon decomposing, carbon is released back into the atmosphere.
4) Some of the carbon that is not released back into the atmosphere eventually become fossil fuels.
5)These fossil fuels are then used for man-made activities, which pumps more carbon back into the atmosphere.
Carbon in the atmosphere is present in the form of carbon dioxide. Carbon enters the atmosphere through natural processes such as respiration and industrial applications such as burning fossil fuels.

2. In July, a student tested the soil in two plots and calculated the
concentration of nitrogen compounds present in each plot. The student
then planted 20 seedlings in the first plot and allowed them to grow.
Nothing was planted in the second plot. The student tested the soil in both
plots again after one month. The concentration of nitrogen compounds
had decreased in the first plot but had remained the same in the second
plot. Which of the following best explains the decrease in nitrogen
compounds in the first plot? *
A. The nitrogen compounds had broken down into elements.
B. The nitrogen compounds were absorbed by the seedlings for their growth.
C. The nitrogen compounds escaped through air pockets created by the seedlings'
roots.
D. The nitrogen compounds had evaporated because of the warm summer
temperatures.
Answer: B. The nitrogen compounds were absorbed by seedlings for their growth.
Explanation:
For the plant to have energy accessible when and where it needs it to maximize yield, nitrogen is essential. As proteins and enzymes control water and nutrient intake, this important nutrient is even present in the roots. Thus, option B is correct.
What nitrogen compounds were absorbed by the seedlings?Plants absorb ammonium and nitrate during the assimilation process, and these substances are then converted into organic molecules containing nitrogen, such as DNA and amino acids.
Plants may absorb substances from soils like nitrate, nitrite, ammonia, and ammonium, which are subsequently utilized to create proteins in both plants and animals.
Therefore, The nitrogen compounds were absorbed by the seedlings for their growth. After they reach three inches in height, seedlings should be fertilized; after that, they can get weekly fertilization until being transplanted.
