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)
Answer:
The lac operon in E.coli regulates genes that code for enzymes required
for breakdown of lactose. The lac operon is an inducible operon that is
activated in the presence of lactose.

This topic is very variable in mammals this typically lasts from ten hours it to ten days.
I think the type of epithelial tissue is the simple columnar epithelium.
The Vermiform appendix is a blind-ended tube connected to the cecum, from which it develops in the embryo. The cecum is a pouch like structure of the colon, located at the junction of the small and the large intestines. A simple columnar epithelium is a columnar epithelium that is uni layered. It lines most organs in human of the digestive tract including the stomach, small intestine and large intestines.
