Answer:
last one
Explanation:
because they have no nucleus of any membrane bound organelles
Ionic bonding is a type of chemical bonding that involves the electrostatic attraction between oppositely charged ions, or between two atoms with sharply different electronegativities, and is the primary interaction occurring in ionic compounds
Hope this helped :)
Answer:
What is a monomer?
A monomer is a molecule that can react together with other monomer molecules to form a larger polymer chain or three-dimensional network in a process called polymerization.
What is a polymer?
Polymers are materials made of long, repeating chains of molecules. The materials have unique properties, depending on the type of molecules being bonded and how they are bonded. Some polymers bend and stretch, like rubber and polyester.The term polymer is often used to describe plastics, which are synthetic polymers.
Answer:
Explanation:
1) The simplest structure is cubic system like simple cubic, body-centered cubic and face-centered cubic in the crystal system.
2) Yes, all minerals have crystal structures because minerals have definite crystal structure. Minerals are solids that are formed naturally through the inorganic processes. Some mineral properties are density, shape, color and hardness.
3) Minerals are the naturally occuring inorganic substances which have ordered atomic arrangement, they are not made by humans that's why we can't predict the specific structure of majority of minerals.
