Two advantages of SI units are:
- SI unit is rational system of units, that means one unit denotes one physical quantity.
- SI units are internationally accepted which makes researchers and scientist calculations
Answer:
1. Surface (substratum) is preconditioned by environment molecules.
4. Microbes attach and detach from the preconditioned surface.
2.Quorum sensing and the establishment of the extracellular matrix commences as microbes attach more stably.
3. Biofilm matures and some microorganisms escape to the plank-tonic state.
Explanation:
Biofilm is a process in which microorganism irreversibly attach and grow on the surface to produce extra cellular polymers that facilitate formation of matrix. The biofilm process takes three days for the formation after which thickness of plaque increases. There are 4 main steps in biofilm formation. Surface is preconditioned by environment molecules. The microbes attach the preconditioned surface. Establishment of extra cellular matrix and finally biofilm matures.
Answer:
The given muscles can be categorized into following categories:
Smooth muscles: These are involuntary muscles and non-striated muscles which are usually found within the walls of internal organs such as stomach, intestine, uterus et cetera.
Cardiac muscles: These are involuntary and striated muscles which are only associated with the heart.
Skeletal muscles: These are voluntary in nature and striated in structure. They are anchored to the bones with the help of tendons. They help in skeletal movement such as maintaining posture, locomotion et cetera. For example, hand muscles and neck muscles.
