The skeletal system protects the internal organs as it gives the body shape, form, and mobility while providing protection for internal organs.Bones/the skeletal system also protect internal organs from injury by covering or surrounding them. For example, the skull(cranium) protects the brain
401 of these offspring are expected to have long plumage.
To calculate the number of these offspring that are expected to have long plumage the following cross multiplication calculation must be performed:
- Total birds = 72 + 252 = 324
- Long plumage birds = 55 + 75 = 130
- 324 = 130
- 1000 = X
- 1000 x 130/324 = X
- 130000/324 = X
- 401.23 = X
Therefore, 401 of these offspring are expected to have long plumage.
