The answer to the blank i think is bond im not 100% sure though..
The mechanoreceptor that is located deeper in the skin and responds continuously to stimulation and is associated with perceiving stretching of the skin is called Ruffini corpuscle.
Mechanoreceptor is a sensory receptor that responds to mechanical pressure. They are connected with sensory neurons that convert this mechanical pressure into electrical signal. It is of four types-
1. Merkel corpuscles- detect pressure and roughness on skin.
2. Ruffini corpuscles- detect deep tension in skin, skin stretch.
3. Meissner corpuscles- perception of light touch and slip on skin.
4. Pacinian corpuscles or Vater-panician corpuscles- detect rapid vibrations.
When these receptors sense a stimuli they gets excited and generates an impulse that travels through the nerve cells into the brain.

Answer:
None of the choices would lead to all identical gametes.
Explanation:
Gametes are sex cells produced by sexually reproducing organims via a process of cell division called MEIOSIS. Meiosis is a cell division process which produces four (4) daughter cells (gametes), which are genetically different from the parent cell.
The difference in genetical content is as a result of a process unique to only meiosis called CROSSING-OVER OR RECOMBINATION. This process ensures that the genetic content of the gametes are altered. Hence, since gamete formation is done via meiosis, none of the scenarios in the option will lead to all identical gametes.
Answer:
Damaged muscle tissue is replaced by fibrous scar tissue. This is called as 'Fibrosis'. Thicker than the surrounding tissue, scar tissue is paler and denser because it has a limited blood supply; although it takes the place of damaged or destroyed tissue, it is limited in function, including movement, circulation, and sensation.
Dense irregular connective tissue contains fibroblasts scattered amongst randomly oriented collagen fibers, whereas muscular tissues contain multinucleated muscle cells that are able to contract upon stimulation. Because the connective tissue cells cannot contract, the muscle will lose strength, and so muscle function will become impaired.
