Cartilage connects the sternum and ribs. There are 7 true ribs, 3 false ribs, and 2 floating ribs. They are all connec
ted to the sternum using cartilage.
Answer:
B) 300
Explanation:
There are two types of alleles present for wing type in this population of Drosophila, c and c+. Various combinations of these two alleles will produce different phenotypes.
c+c+ : straight wings = 45
c+c: straight wings = 70
cc: curly wings = 35
Total flies = 150
Each fly has one gene with two alleles for wing type. Hence 150 flies will have 300 alleles in the gene pool.
The four reasons are
1) There is an over population.
2) There is a genetic variation in certain offspring that is helpful to survival.
3) The species struggle for survival.
4) The ones that lives will reproduce and pass on their genetic variation.

Rising sea levels would consume coastal islands/nations cause over population since everyone would move inland and raising food costs?
