C.500 g that should be the answer I hope I helped :)
Answer:
Genetic drift is a mechanism of evolution in which allele frequencies of a population change over generations due to chance (sampling error).
Genetic drift occurs in all populations of non-infinite size, but its effects are strongest in small populations.
Genetic drift may result in the loss of some alleles (including beneficial ones) and the fixation.
Genetic drift can have major effects when a population is sharply reduced in size by a natural disaster (bottleneck effect) or when a small group splits off from the main population to found a colony (founder effect).
Answer:
fibrous root because they form a wide network of thin roots that originate from the stem and stay close to the surface of the soil.
No they cant be mechanical because then something would have to generate their rays through the inventing of a machine.
