Answer:
B
Explanation: First degree only makes the skin turn red
Answer:
2n to n, n to 2n
Explanation:
Meiosis is known as reductional division because in meiosis the chromosome number gets reduced to half in daughter cells so when sperm and egg cells undergo meiosis than the chromosome numbers get reduced from 2n to n. In humans, the chromosome number is 46 and it gets reduced to 23 after meiosis.
When egg is fertilized by the sperm than the two chromosomes comes in the same cell and the number goes from n to 2n that mean in human it goes from 23 to 46.
Answer:
The sample most useful in identifying the person who committed the crime will be fingerprint. Fingerprints are the impression of finger ridges left on the surface of an entity or area in a crime scene. No two individuals can have same fingerprints. No two fingers of a same individual can produce same fingerprint. These are not found to be similar in identical twins. Fingerprints can be collected from porous and non--porous surfaces. These can be collected easily from crime scene. These fingerprints can be matched with specimens obtained from victims or offenders in order to establish the identity. The physical fingerprint analysis is more superior than DNA fingerprinting as in DNA fingerprinting the results obtained from twins could be similar but physical fingerprints cannot be similar because of different ridge characteristics. Therefore, valuable technique for identification of person who committed the crime.
A crystals shape is determined by the arrangement of the atoms or molecules inside the crystal.
