both are single cells that carry out the functions of life
Explanation:
Both eukaryotic and prokaryotic cells are single cells according to the cell theory and they carry out the functions of life.
- The cell theory postulates that all living organisms are made up of cells and that the cells are the basic organizational unit of life.
- It also proposes that all cells arise from pre-existing cells.
Eukaryotic cells differs from prokaryotic cells in that they have true nucleus and membrane bound organelles.
Despite this seeming different, both cells are able to carryout different life functions as unit and when they combine together, they advance into higher organization of life.

Passive transport is the movement of biochemicals and other atomic or molecular substances across cell membranes without need of energy input. On the other hand, active transport <span>is the movement of molecules across a cell membrane from a region of their lower concentration to a region of their higher concentration which needs energy input. </span>
Answer:
The correct answer is (b) 1%
Explanation:
Represented in an ecological energy pyramid, the seals would be in the third position from the bottom as <em>secondary consumers</em>.
In this example, the <em>base of the pyramid </em>will be represented by the coconut palms, the primary producers, also known as autotrophs, which create their food by <em>taking their energy from non-living sources</em> of energy, like the sun.
The second level consists of primary consumers. Herbivores feed solely on <em>primary producers</em>, in this case, the coconut crabs.
The third level would be the secondary consumers, usually carnivores and omnivores, in this case, the seals.
In this example, as seals would be the secondary consumers located at the third level of the pyramid from the bottom, they will receive about 1% of energy.
