"Eukaryote" roughly translates as "truly nucleated" and refers to organisms with a membrane-bound nucleus.
Such membrane-bound organelles are thought to have arisen via the invagination of the cell's own plasma membrane.
Other organelles such as the mitochondria and the chloroplast are believed to have once existed as separate organisms, but which were engulfed by other cells, forming a symbiotic relationship.
Include grand parents.
Nuclear family is a family group with 2 parents and their children. This is a type of family structure. It typically centered on married couple. This is in contrast to other family group such as single parent, extended types. Extended family extends beyond the nuclear family usually extended by grand parents. Usually they live under one roof.

Option C Habitat.... Polar bears are only found in the Arctic. The most important habitats for polar bears are the edges of pack ice where currents and wind interact, forming a continually melting and refreezing matrix of ice patches and leads (open spaces in the ocean between sea ice).
<h2>
Answer:</h2>
Antagonistic.
<h2>
Explanation:</h2>
- Muscles generally work in groups or pairs.
- Muscles are connected to bones via tendons, these tendons and muscles help in movement of a joint.
- When a muscle is put in contraction, usually only one bone moves. For example on contraction of biceps of the arm contracts then the radius moves but the scapula does not move.
- This type of muscle action is called antagonistic muscle action. In which the muscle which is working is called the prime mover or agonist and the relaxing muscle is called the antagonist.
Result: The muscle action in which a muscle works against another muscle is called antagonistic.
