Answer:

It's a little difficult to see the difference between the finch 1 and finch 2 population lines, but their trends should match those of the food. This answer is assuming the finch 1 population aligns with the seeds line and the finch two population lines up with the fruit line: <u>The finch 1 population has a beak adapted to eating seeds and the finch 2 population has a beak better adapted to eating fruit</u>

Explanation:

Since we are given data for both the food source and the finch population, the answer will most likely reflect that. Therefore eliminating choices A (disease) and C (feathers). Again, this answer is assuming the finch 1 population aligns with the seeds line and the finch two population lines up with the fruit line. The lines for the finch population will match with the availability of food, so less seeds mean less finch 1 and when the amount of seeds rise up you can see the population of finch 1 also rises.

Bone formation begins when ____________ secrete the initial semisolid organic form of bone matrix called ____________ .
butalik [34]

Answer:

a. osteoblasts

b. osteoid

Explanation:

Osteoblasts are the fundamental cell of bone tissue. They are the cells that synthesize the bone matrix called osteoid from which it is made from the skeleton of bone fish, to the skeleton of humans. Since the bone skeleton is an evolutionary paraphiletic characteristic (it is present in several taxonomic groups that have evolved from the same ancestor).

Osteoblasts are responsible for the development and growth of bones during the juvenile stage of individuals and are also responsible for maintaining adult bone and regenerating bone when it breaks.

Osteogenesis is the process of differentiation of osteoblasts. The cells from which osteoblasts differ are called osteoprogenitors. The differentiation of osteoprogenitor cells, which come from the mesoderm, periosteum or bone marrow, is induced by growth factors called bone morphogenetic proteins (BMPs), capable of inducing the growth of bone, cartilage or connective tissue. When an osteoprogenitor cell receives a BMP signal, it quickly begins to express the genes to generate collagen, osteonectin and alkaline phosphatase, among other compounds necessary for bone growth. When the bone grows, it ends up wrapping some of the osteoblasts and they lose their ability to replicate, at that time they are dedicated to bone maintenance and not to their synthesis and are called osteocytes.
