Answer:
A cell wall is a structural layer surrounding some types of cells, just outside the cell membrane. It can be tough, flexible, and sometimes rigid. It provides the cell with both structural support and protection, and also acts as a filtering mechanism.
Explanation:
A cell wall is a rigid, semi-permeable protective layer in some cell types. This outer covering is positioned next to the cell membrane (plasma membrane) in most plant cells, fungi, bacteria, algae, and some archaea.
From the options that factor that does not effect the rate of enzyme reaction is : ( D ) Amount of product.
Enzymes are substances found in organisms that catalyzes the rate of chemical reaction occurring in an organism. during the chemical reaction the enzyme remains intact and is not utilized during the process.
Some of the process that may Inhibit the performance of an enzyme(s) includes ;
- pH ,
- The substrate concentration,
- Temperature and
- The concentration of the enzyme.
The amount of the product does not affect the performance rate of the enzyme because enzymes functions in chemical reactions and not physical reactions
Hence we can conclude that the factor that does not effect the rate of enzyme reaction is the Amount of product

Answer;
-Phospholipids and protein
Explanation;
-The plasma membrane is composed of a phospholipid bilayer arranged back-to-back. It is also covered in places with cholesterol molecules and proteins. The plasma membrane is selectively permeable and regulates which molecules are allowed to enter and exit the cell.
- The membrane is an extremely thin layer of lipids and protein that forms outer boundary of every cell, It controls movement of molecules between the cell and its environment, Participates in joining cells to form tissues and organs and also plays important role in the ability of a cell to respond to changes in the cell's environment.
Answer:
Metaphase!
Explanation:
During metaphase, the sister chromatids line up where they will eventually be pulled apart during anaphase.
