Answer:
The correct option is A) Stratified epithelium.
Explanation:
Stratified epithelium is characterized by being formed by more than one layer of epithelial cells. According to the morphology of the cells of the outermost layer, they are classified as keratinized stratified flat epithelium when it has several layers and the outermost are flattened cells and with keratin. The most prominent location of this epithelium is in the skin, forming the epidermis. Its function is to protect and cover surfaces that are in direct contact with the outside or with irritating or traumatic substances.
The correct answer is (B) they travel faster than S waves
As the interior of the earth is incompressible, the P-waves moves much faster and transmit their energy through the medium and travel very fast as compared to the S waves. In case of S waves, they are slow because the movement of medium is perpendicular to the direction of propagation of waves’ waves travel 60 times faster than S waves. The variation in speed of travel is because the earth reacts differently to both the waves.
Answer:
mutation in DNA
Explanation:
Mutations are changes in the genetic code that can occur in many ways. Each time a cell divides, say, DNA must be copied into two copies, one copy for each new cell. Although this copying is very precise, it is still not perfect - for about every billion accurately copied databases, one is mistranslated.
Another source is DNA damage, which can occur spontaneously through the normal life of the cell, or through external toxins or negative influences (ultraviolet radiation, for example). Through evolution, cells have developed a very complex system for repairing changes in DNA, but these systems not only have limitations but can sometimes cause additional errors themselves.
