Describe the differences between a fertilized egg and an unfertilized egg.
Answer: Microtubules are straight and hollow tubular structures with no limiting membrane arranged in different bundles which are made of globular protein called tubulin while microfilaments are long and fine thread like structures which are made up of non tubular contractile protein called actin and myosin.
Explanation: Microtubules may function alone or join with other proteins to form more complex structures like cilia, flagella or centrioles and perform various functions like
1) Act as conveyer belts which allow movement of granules, vesicles, protein molecules and other organelles like mitochondria to different part of the cell.
2) Form the spindle fibers which separate the chromosomes during mitosis and responsible for the movement of centrioles.
Microfilaments are present throughout the cytoplasm. They are responsible for:
1) Give structure strength and provide resistance to cell against the pulling forces
2) Responsible for cellular movements like contraction, gliding and cytokinesis (partition of cytoplasm during cell division)
According to Max Weber, what factor or factors are responsible for social stratification?
B. class, prestige, and power

He can see if they are green and he can also determine where they came from.
Answer:
Primary succession is the type of succession which occurs in areas where there was no form of life before or it occurs in areas where the previous form of life has fully been eradicated with not even the soil present from that ecosystem. For example, a land where lava eruption has occurred.
A secondary succession is the type of succession which occurs in areas where there was life before which was removed by natural disasters like fire, flood or by human activities. This kind of areas might have the soil texture and composition to support life again. But for primary succession, the rocks will eventually have to be broken down and soil particles would form with the passage of time. Then only the land will be able to support life. Hence, primary succession takes longer to occur.
