hey mate ....ur answer
1.The differences are-Bacterial cell (Prokaryotic Cell)- Nucleus with nuclear membrane is absent.Genetic Material is present as Nucleoid Animal Cell (Eukaryotic Cell)-A well-defined nucleus with nuclear membrane is present.Genetic material- Present inside the nucleus.
3.The husk of a coconut is made up of sclerenchyma tissue.
4.A bone is a hard connective tissue, while cartilage is soft connective tissue. Bones form the skeletal structure of the body, whereas cartilage is present in nose, ear, ribs, larynx, and joints and also act as a shock absorber in these joints.
6.hybridization results from the combination of the s orbital and all three p orbitals in the second energy level of carbon. It results in four hybrid orbitals and occurs when a carbon atom is bonded to four other atoms. This kind of hybridization occurs when a carbon atom is bonded to three other atoms.
