The skeletal system provides a frame to
support and protect the body and allows the
body to move.
Due to the overproduction of offspring with only finite resources, species begin to engage in competition for survival. In order to increase their chance of survival, certain species will begin to develop genetic variations that allow them survival advantages.

Answer:
individual organisms of the same species living in the same geographic location at the same time makes up a population.
Explanation:
Answer:
Explanation:
From the question, the total population = 171 i.e (80+71+21)
Genetic frequency therefore; BB = 71/171 = 0.42
Bb = 80/171 = 0.47
bb = 20/171 = 0.12
Allele frequency therefore;
Allele B = 0.42+(0.50×0.47) = 0.66
Allele b = (0.50×0.47)+0.12 = 0.36
Note all values were rounded up to two significant figures
