When cells come together they form tissues
Answer:
Option (B).
Explanation:
Genetic diversity may be defined as the number of total genetic characteristics of a species. Genetic diversity helps the population to adapt in the changing environment. Crossing over provides a source of genetic diversity.
Crossing over is the process of exchange of genetic material during the process of meiosis. Thus, crossing over increases the variation of genetic characteristic in the haploid gamete cells.
Thus, the correct answer is option (b).
Answer:
96000YEARS
Explanation:
Given that 1/28 = 8 half lives
this means that 8 half lives ,
and the given fossil should have 1/28 of the isotope
8 half lives = 1200 x 8
= 96000years
therefore the predicted Neandertal fossils is 96000years
