Answer:
Structure of a leaf
The cuticle helps retain water inside the leaf cells. The epidermis houses the guard cells which regulate the movement of water into and outside the cell. Guard cells do so by controlling the size of the pores also called stomata. Mesophyll: This forms the middle layer of the leaf.

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.

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.

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

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.
