Step 1:
The bacterium cell must copy its DNA so the new cells will have DNA. DNA or, deoxyribonucleic acid, has all of the information the bacterium will need to survive, so it is important it gets copied. The DNA is tightly wound so it is in a neat package called a chromosome.
Steps 2 and 3:
The bacterium now grows larger. This allows for some separation between the two DNA copies that are inside the cell. A division develops in the middle of the bacterium. This division eventually completely divides the bacterium in half. This is called cytokinesis.
Step 4:
Each cell is now called a daughter cell and they separate.
The steps of binary fission
binary fission
Binary fission results in two identical daughter cells. This is a type of asexual reproduction, or creating genetically identical offspring. If humans were able to reproduce using binary fission, it would look something like this: your mother or father would grow larger, and inside all of his or her DNA would be copied. Eventually your parent would split in half creating an identical clone.
Answer: If you have an excess of enzyme but not enough substrate, the reaction will be limited by the substrate availability.
Explanation: Once you add more hydrogen peroxide to the solution, the reaction rate will increase as more substrate molecules can collide with the enzyme, forming more product.
Answer: A variety of substances will dissolve oil, including gasoline and carbon tetrachloride -- both of which have non-polar molecules. Acetone is a special class of solvent called “dipolar aprotic” that, depending on the circumstances, can act as a weak acid or base; it dissolves oil and mixes with water as well.
Explanation:
Hemoglobin has tetrahedral structure containing four heme groups that surround a globin group.
Heme is ringlike organic compound also known as a porphyrin to which an iron atom is attached. There are four iron atoms that bind four oxygen atoms and transport them to tissues.
<h2>a) is the correct option </h2>
Explanation:
The extracellular domain of the transmembrane receptor protein acts as binding site for primary messenger molecule whereas the transmembrane domain holds the receptor within membrane and the cytosolic domain has intrinsic tyrosine kinase activity, all these helps in proper cell signaling
If because of any mutation there is change in shape of the extracellular domain then that molecule that normally binds to the receptor protein will no longer attach hence cellular response will be deactivated
