Answer:
Prokaryote/Bacteria.
Explanation:
The features of the cell which is mentioned in this question match with that of prokaryotic organisms like bacteria.
The salient features of a bacteria are mentioned as under:
1) Presence of nucleoid instead of nucleus: Bacteria do not have well defined nucleus like eukaryotes so their chromosomal material is freely scattered in the cytosol.
2) Plasma membrane: They have plasma membrane which surrounds their interior i.e. their cytosol and other organelles.
4) Cell wall: Outside their plasma membrane they have a rigid cell wall made up of peptidoglycan which provides them a specific shape.
3) Ribosomes: They have a lot of ribosomes in their cytosol.
Answer:
The correct answer would be carrying a box.
Work is done only when force is able to cause a displacement.
It can be calculated by multiplying the force applied (F) and the displacement (S) caused.
W = FxS
If the force applied and displacement are in the same direction then the value of work done is taken as positive.
In contrast, when the force and displacement are in opposite directions the value of the work done is taken as negative.
Lastly, when there is no displacement then the work done is zero.
In carrying the box, there is no displacement occur due to which work done is zero.

Disaccharides are formed by two monosaccharides joining together, for example, lactose. Polysaccharides are long chains of monosaccharides, including starch.</span>
