Which of these changes to the cell would cause the greatest reduction in the activity of catalase? A. A decrease in the concentration of hydrogen and oxygen B. An increase in the concentration of hydrogen peroxide C. A strong bonds between carbon atoms that cannot be broken D. Ionic bonds between carbon atoms and oxygen atoms
Answer:
A. A decrease in the concentration of hydrogen and oxygen
Explanation:
Catalase's function is to catalyze the decomposition of hydrogen peroxide (H₂O₂), which is a toxic substance for cells, into oxygen (O) and water (H₂O).
The following chemical reaction can represent the catalase enzymatic action:
2H₂O₂ + Catalase → H₂O + O₂
Due to this, as oxygen and hydrogen (H) are structurally essential for the catalase reaction, the decrease in the concentrations of these substances would also reduce the enzyme's action potential.
What was Earth's early atmosphere like?
The sun shining on a tidal pool during a hot day heats the water. As some water evaporates, the pool becomes saltier, causing.
As water evaporates off salt water, the water gets saltier, and dissolved oxygen in the water reduces.
Dissolved oxygen and solute concentrationThere is an inverse relationship between the dissolved oxygen in water and the concentration of solute.
Thus, as water evaporates off the tidal pool, available free oxygen decreases accordingly just as the water becomes more salty.
In other words, the more water in a solution, the more free oxygen, and vice versa.

how can we conserve our natural resources in the environment?
Answer:
Switching to sustainable energy sources such as solar power, hydroelectric power and wind power can reduce the amount of fossil fuels being used up. Fossil fuels are natural resources from the environment, but when burned the waste product of it is released into the environment and can potentialy affect other natural resources. Switching to a renewable energy source can help conserve natural resources. Renewable energy sources can be used to harness the energy we need without producing harmful products that affect the environment and it's resources.

What are the effects of the mass extinction of permian on marine organisms and insects.
Answer:
At the end of the Permian, conditions became unsuitable for most life and about 95% of marine species were eliminated as well as 70% of terrestrial species in a very short period of time, in geologic terms. It was also one of the few known mass extinctions of insects. Many plant species also went extinct.Which is NOT a
benefit of
biodiversity?
A. climate change
B. control of pests
C. clean air and water
D. control of soil erosion
Answer:
C. clean air and water
Explanation:
The reason why this is NOT a benefit of biodiversity is because Plants and Animals really like to mess things up, you know, they really just don't care about what they're destroying, so if there is a crocodile in the water, then it won't care about just playing with some mud, that's why, they make the water dirty, specially while attacking land animals that come to drink the water. Another thing is that they can just p.o.o.p which will not make anything better.
so hence, your answer is C. Clean air and water

20. Does facilitated diffusion require energy for the cell?
Answer: no
Explanation: The solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. This process is called passive transport or facilitated diffusion, and does not require energy.
