Answer:
Once osteoblasts have surrounded themselves with the extracellular matrix of bone tissue, they remain inside little chambers called <u>lacunae</u>, where they carry on the metabolic functions that maintain bone tissue. At this point, they are called osteocytes.
Answer:
Keystone species
Explanation:
Keystone species are such species that had a large effect on the natural environment. Such species are very important species as they play key role in determining and maintaining the the structure of an ecosystem and also decide or fix which type of species will be there in that environment and what will be the number of those species in that particular community. Without these keystone species an ecosystem could completely cease or all species could not work in that same manner all-together. Wolf is one of an important keystone species in the ecosystem.

How do limiting factors affect population size?
Explanation:
Limiting factors are factors that affects the size of a population and slows down its growth rate or stop it in its entirety.
These factors include food, space, temperature, sunlight etc.
Limiting factor like food can affect a population greatly like not having enough preys in a forest, therefore the predators are starved to death or even in a fish pond where there is high competition for space (overpopulated) which leads to oxygen deficiency i.e they compete for oxygen as well, and this can lead to death as well.
Answer: Colonial organisms are the result of many identical individuals joining together to form a colony. These cells are partly dependent on each other to start with. But, later evolutionary events resulted in the obligatory relationships among them resulted in multicellularity.
