Organs are the structures composed of specialized tissues designed to perform specific functions in plants and animals.
Organs are the structures made up of similar types of tissues, These work in coordination to perform a similar type of function. The heart, kidney, lungs, stomach are all examples of organs. These are differentiated structures that perform a specific task.
Tissues are the mass of cells that are of similar type. The differentiated cells combine together to form a tissue. These cells also work in coordination so that the tissue can perform a certain type of function. Tissues can be plant tissue or animal tissue depending upon whether they have plant cell or animal cell.

Answer:
D. The ability to allow materials to cross a membrane
Explanation:
It all has to do with the size of the materials trying to pass through. All other options do not make sense. Thickness, flexibility, and amount of molecules do not describe permeability.
Answer:
Black-(I) 22-(F) 38-change was +16 degrees
White-(I) 22-(F) 24-change was +2 degrees
Green-(I) 22-(F) 29-change was +7 degrees
Red-(I) 22-(F) 31-change was +9 degrees
Blue-(I) 22-(F) 33- change was +10 degrees
Explanation:
I= initial temp, F=final temp
Answer:
C. lack the enzymes to reduce N2 and NO3- to NH4+
Explanation:
Nitrogen fixation is a process by which atmospheric nitrogen (N2) is converted into ammonia (NH3) so that can be used in metabolic pathways (e.g. biosynthesis of macromolecules). Nitrogen fixation is performed by Archea and bacteria such as Azotobacter (usually in symbiosis with Leguminosa plants).
Nitrogen assimilation is a process in which organic compounds are made from inorganic nitrogen.
