Place the following events in the correct order. Rank the options below. Secondary ossification centers form in the epiphyses of long bones. open choices for ranking No answer Osteoblasts lay down bone matrix, forming spongy bone in the primary ossification center. open choices for ranking No answer A primary ossification center forms as blood vessels and osteoblasts invade. open choices for ranking No answer The cartilage model is almost completely ossified; the remaining cartilage becomes the epiphyseal plate and articular cartilage. open choices for ranking No answer The epiphyseal plate becomes the epiphyseal line, and all cartilage (except articular) has become bone. open choices for ranking No answer Chondroblasts produce a cartilage model that is surrounded by a perichondrium. open choices for ranking No answer The perichondrium of the diaphysis becomes the periosteum, and a bony collar is produced. open choices for ranking No answer Chondrocytes hypertrophy, die, and calcified cartilage forms. open choices for ranking No answer

Two male mice, which we will call male a and male b, are both phenotypically normal. male a was from a litter that contained half phenotypically normal mice and half dwarf mice. the mother of male a was known to be homozygous for the normal igf2 allele. male b was from a litter of eight mice that were all phenotypically normal. the parents of male b were a phenotypically normal male and a dwarf female. male a and male b were put into a cage with two female mice that we will call female a and female b. female a is a dwarf and female b is phenotypically normal. the parents of these two females were unknown, although it was known that they were from the same litter. the mice were allowed to mate with each other, and the following data were obtained: female a gave birth to three dwarf babies and four normal babies. female b gave birth to four normal babies and two dwarf babies. which male(s)mated with female a and female b? male a with both females male a with female b, and male b with female a male a with female a, and male b with female b could not be determined male b with both females
