Answer:
A contractor who hired two sub-contractors to help work on the house would be most like to osteoblast.
Explanation:
Osteoblasts are cells that build bone, just like contractors build a house. They are cells capable of synthesizing the bone matrix, allowing the formation and growth of bone.
As bone-forming cells, osteoblasts have a large number of mitochondria and a developed Golgi apparatus. They can multiply until they are covered by the bone matrix, becoming known as osteocytes.
The other options are not correct because:
- <em>Osteogenic
: related to bone.</em>
- <em>Osteocycle
: bone cell in its mature shape.</em>
- <em>Osteococlast : cells capable of remodeling the bone, breaking it and allowing the action of the osteoblasts.</em>
The first line of defence (or outside defence system) includes physical and chemical barriers that are always ready and prepared to defend the body from infection. These include your skin, tears, mucus, cilia, stomach acid, urine flow, 'friendly' bacteria and white blood cells called neutrophils. Hope this helps.
