Answer:

Biologists measure the number of trophic levels in an ecosystem so as to check its stability and health.

Trophic levels are the feeding position in a food chain such as primary producers, consumers, etc. They are positions that an organisms occupies in a food chain (series of steps in which organisms transfer energy by eating or being eaten);- what it eats and what eats it.

Three cells each contain a 98% water wash were soaked in different solutions cell number one is so funny solution containing 100
stepladder [879]

Answer: Cell number one is an hypotonic solution, cell number two is an isotonic solution, and cell three is an hypertonic solution.

Explanation:

Cell number one which is a 98% water content is added the 100% water solution, water moves from low to high concentration. Therefore, the water moves from the solution into the cell, which is hypotonic.

Cell number two which is a 98% water content added with a 98% water solution. These two solutions are equal to one another, so the water does not move. This is isotonic.

Cell number three which is a 98% water content added with a 80% water solution. Water moves from high to low concentrations, so water moves from the cell to the solution. The water leaves the cell, which is an hypertonic.

What are Intramembranous and endochondral ossification?
erma4kov [3.2K]

Answer:

The direct conversion of mesenchymal tissue into bone is called i<u><em>ntramembranous ossification</em></u> .The process by which a cartilage intermediate is formed and replaced by bone cells is called <em>endochondral osssification.</em>

Explanation:

Intramembranous ossification  is one of the two essential process during the fetal development  of the gnathosome skeltal system by which rudimentary bone tissue is created. It is the process of bone development from fibrous membranes. It is involved in the formation of the flat bones of the skull, mandible and the clavicle. This type of ossification also helps in healing of bone fractures.

Endochondral Osssification: Method of forming a bone through cartilage intermediate. It is also involved in the formation of long bones.
