The answer for the above question is Mutation.
Mutations are random spontaneous changes that occur suddenly in the DNA. A single mutation can have a large effect, however in may cases evolutionary changes are based on the accumulation of many mutations. The gene flow is any movement of genes from one generation to another and is an important source of mutation
Explanation:
Conjunctivitis is the inflammation of the transparent mucous membrane, that covers the white part of the eye.
- Bacterial conjunctivitis can be cure with the help of antibiotics, but viral cannot.
- The discharge from eye is clearer and less thick in viral conjunctivitis as compared to bacterial.
- Viral conjunctivitis is self-limited, while bacterial is not.
- Viral can cause painful swelling in lymph node nearest the ear, which is not there in bacterial conjunctivitis.
Answer:
Using irrelevant sites for the task
Explanation:
1. C
2. C
3. In elastic deformation, the deformed body returns to its original shape and size after the stresses are gone. In ductile deformation, there is a permanent change in the shape and size but no fracturing occurs. In brittle deformation, the body fractures after the strength is above the limit.
4. Normal faults are faults where the hanging wall moves in a downward force based on the footwall; they are formed from tensional stresses and the stretching of the crust. Reverse faults are the opposite and the hanging wall moves in an upward force based on the footwall; they are formed by compressional stresses and the contraction of the crust. Thrust faults are low-angle reverse faults where the hanging wall moves in an upward force based on the footwall; they are formed in the same way as reverse faults. Last, Strike-slip faults are faults where the movement is parallel to the crust of the fault; they are caused by an immense shear stress.
DNA is tightly packed in the nucleus. DNA molecule wraps around histone proteins to form tight loops called nucleosomes. Nucleosome is a structure formed by two molecules of each H2A,H2B,H3&H4. They associate to form an elliptical bead like structure. One nucleosome is covered by a H1 protein and 1 3/4 of DNA wraps around one nucleosome. These nucleosomes coil and stack together to form fibre called chromatin which constitutes the genetic material inside the nucleus.
