Diploid cells = 2n = 46
Haploid cells = n = 23
therefore, there are 23 chromosomes in haploid cells.
Answer: D. Galaxies show a red shift, indicating they are moving away from each other.
Explanation:
Galaxies seem to show a red shift which indicates that the galaxies are moving away from each other. This provides evidence for the Big Bang theory because the theory posits galaxies will keep moving away from each other.
This is because when an explosion happens, matter moves away from the point where the explosion happened. If the Big Bang happened therefore, galaxies will move away from the source which is why galaxies are moving away from each other.
Answer:
C. Organisms are now divided into three kingdoms.
Explanation:
In the early 1860s, a German scientist named Ernst Haeckel suggested using a three kingdom system of classification. Haeckel's three kingdoms were Animalia, Plantae, and Protista.
The only exception to the six chromosomes per cell rule for mosquitoes would be gametes or sex cells when cells in the ovary undergo meiosis the result is egg or sperm cells which haploid
