This week, 300 tickets were sold to the school play. this is 120 percent of the number of tickets sold last week. how many tickets were sold last week for the school play?

300=120/100* number of tickets sold last week.

So last week's number of tickets=300÷(120/100)=300*100/120=30*100/12=5*100/2=5*50=250 tickets

Step-by-step explanation:

homozygous. one is homozygous, while two is heterozygous.

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
