Answer:

Osteochondral Progenitor cells

Explanation:

Osteochondral Progenitor cells are cells that can form a specific type of tissue. These cells form cells that can give rise to the bone and its components, especially fibers. These Progenitor cells originate from the mesenchymal stem cells.

The cells which form the bone are known as the osteoblasts and the cell which forms the fiber is known as the chondroblasts.

Thus, Osteochondral Progenitor cells is correct.

mezya [45]

Answer:

Adjustment knob (coarse) ---> Causes stage (or objective lens) to move upward or downward

Arm ---> Serves as a handle for carrying the microscope

Condenser ---> Concentrates light onto the specimen

Eyepiece (ocular) ---> Contains a lens at the top of the body tube

Field of view ---> Circular area seen through the eyepiece

Iris diaphragm ---> Increases or decreases the light intensity

Nosepiece ---> Part to which the objective lenses are attached

Objective lens system ---> After light passes through the specimen, it next enters this lens system

Explanation:

The microscope is an essential equipment used in science laboratories to view objects which are too small to be seen by the naked eye. Also certain processes which occur at the microscopic level can only be observed using a microscope.

There are many different types of microscopes. The compound light microscope is the one most commonly used in biological laboratories to view tissues and cells of organisms. It uses visible light which passes through two separate lens to magnify the image produced of a specimen.

The various parts of compound light microscope and their respective functions are given below:

Adjustment knob (coarse) ---> Causes stage (or objective lens) to move upward or downward

Arm ---> Serves as a handle for carrying the microscope

Condenser ---> Concentrates light onto the specimen

Eyepiece (ocular) ---> Contains a lens at the top of the body tube

Field of view ---> Circular area seen through the eyepiece

Iris diaphragm ---> Increases or decreases the light intensity

Nosepiece ---> Part to which the objective lenses are attached

Objective lens system ---> After light passes through the specimen, it next enters this lens system

Stage ---> Platform that supports a microscope slide

Stage (slide) clip ---> Holds a microscope slide in position

The government of a flood prone region wants to implement some measure to reduce risk of floods. Which method is likely to reduc

Sonja [21]

Answer:

The correct answer is "preservation of wetlands".

Explanation:

Wetland are areas of lands that are saturated with water, usually comprised by marshes or swamps. Preservation of wetlands help to reduce the risk of floods because wetlands temporarily store and slow the release of stormwater. It has been reported that areas where wetland have been lost, the chances of flood increases by as much as 80 percent. The government of a flood-prone region would likely reduce the risk of floods by preserving its wetlands.
