In cell membrane phospholipids are formed in a bilayer , in which the non polar termed as hydrophobic are present in the interior of bilayer to shield it from water , and polar region termed as hydrophilic is present outward to interact with water inside or outside the cells.
3 is the answer.
Binary fission is a type of asexual reproduction and is the most common method of reproduction in prokaryotes. It may occur in some unicellular (single- celled) eukaryotes..
Eukaryotes use sexual recombination during reproduction to create or generate genetic variation and thus the resulting offspring will have a mixture of the parents' genetic characteristics.
Prokaryotes on the other hand will simply produce clones of themeslves through binary fisson. After the process of replicating its own genetic material, the prokaryote simply divides into two daughter cells that are almost identical in size and that concludes the process.
The white blood cell is called NEUTROPHIL. Neutrophils play important roles in the immune system; they move around the body via the blood stream and when they sense signals that foreign bodies are present, they move to the site of the infection and destroy them. They are among the first set of immune cells that defend the body against infection.
