Catalase is an enzyme which is present in every living organism that is exposed to oxygen. Catalase's activity is affected by temperature, pH and the concentration of substrate. In catalase's case, the substrate is the hydrogen peroxide. If any of these factors change, the effectiveness of the catalase to catalyze the decomposition of hydrogen peroxide will deteriorate. If the temperature and pH change, the shape of the enzyme will change as well. This denaturation of the enzyme will obstruct the hydrogen peroxide molecules to fit in the catalase's active site.

Answer:
A. outside plasma membrane:
1. cell wall 6. flagella
B. outside of the cell
4. fimbriae 5. pilus
C. in cytoplasm
2. nucleoid 3. ribosome
Explanation:
Bacteria is one of the three domains of cellular organisms. Bacteria are prokaryotes, cells that lack a true nucleus and membrane-bound organelle.
The plasma membrane is the outer membrane that enclosed the cytoplasm and cytoplasmic substance. The cell wall is covering the present out of the cell membrane or plasma membrane. Flagella are attached to the plasma membrane but it is present outside of the plasma membrane.
Fimbriae and pilus are the structure present outside of the cell wall and help to attach it to other cells or any surface. Nucleoid and ribosomes are present in the cytoplasm of the bacterial cell.
Answer:
Absolute

Answer:
D. 0.5 ft
Explanation:
Using the scale :
1 : 4000
This means that an altitude of 4000 feets is represented by 1 unit in the model.
Hence,
1 feet in model = 4000 feet actual altitude
Given an actual altitude of 2000 feets above ground level ;
Feets in the model will be x
1 feet = 4000 feet
x = 2000 feet
Cross multiply :
4000x = 2000
Divide both side by 4000
4000x / 4000 = 2000/4000
x = 0.5
Hence, 2000 feets above ground level corresponds to 0.5 feets in model
