1 answer:

5 0

It is a natural acceptable fast process of cleaning contaminated materials in the environment. It is cost effective in cleaning hazardous wastes compared to other methods.This method can easily be done without disrupting normal activities. Residues for this kind of treatment are usually harmless products.

Which property is used to identify the origin of an igneous rock?

slega [8]

Answer: Hardness

Igneous rock derives it's name from the Latin word ignis which means fire. It is formed when the magma after volcanic eruption gets cool and solidified either on the surface of earth crust or inside the earth crust. These rocks are characterized by their hardness. These rocks undergoes no chemical weathering but exhibit very low mechanical or physical weathering may occur. Therefore, hardness is the property which can be used to identify the origin of an igneous rock.

Interpret the model. Drag "True" or "False" to the end of each statement. ResetHelp True False The two lines on the outside of t

Aleonysh [2.5K]

(see attached image)

Answer:

The two lines on the outside of the chloroplast indicate a double membrane: True
The Golgi apparatus is not shown in this cell but this does not mean that this organelle does not occur in the cell: True
The relative dimensions and placement of the membranes and organelles in this model are exact representations of those structures in a living cell: False
The large structure in the center is a nucleus: False
This cell is capable of photosynthesis: True

Explanation:

Chloroplast, like mitochondra, have double membrane called the chloroplast envelope. Hence the first statement is true.
Golgi apparatus is found in all plant and animal cell. It is usually located close to endoplasmic reticulum. Hence this statement is true.
The relative dimensions and placement of the membranes and organelles in this model are not an exact representation of those structures found in living cell. Hence its a false statement.
The large structure in the centre is vacuole and not nucleus. Hence its a false statement.
Since its a plant cell so it is capable of photosynthesis. Hence its a true statement
