I really need answers of following questions..Could you help me?


1.What are the four different types of vertebrate tissues? List examples, functions, and distinguishing features of each class of tissues.




2.How many layers of cells are there between the top of the epithelia and the basement membrane? Are the layers of skin distinct, or is there a gradual change in cellular shape from the basal membrane to the surface layers?




3.Can you observe the striations and nuclei in the skeletal muscle? How many muscle fiber widths do you count across the diameter of your microscope when viewed and high power?




4.What are the three main parts of a neuron? Why are the neurons shaped in this way?




5.Connective tissue is always made of two parts; what are they and give examples of them in bone and blood.




6.What is the approximate ratio of leukocytes to erythrocytes?




7. A theme in biology is the idea that “form follows function.” Describe the structure and function for each type of tissue that you examined and explain the correlation between the two.
