Hello there,
<span>Euglenas are protists, so they are eukaryotes.
</span>Euglena is classified as eukaryotic organism because some of its cell organelles are clearly defined, that is, they are surrounded by membranes.
Hope this helps :))

Answer:
In a scientific experiment, an independent variable is the one which can be changed or manipulated in an experiment. A dependent variable is one which depends upon the independent variable in the experiment. In a experiment if independent variable changes or manipulated, the effect is observed and measured on the dependent variable.
The food being filled to the top for the first day till consumed up to 10 days can be considered as the independent variable, to determine the number of birds come to feed in different time periods (6.am and 6pm) is the dependent variable.
Analogy, in biology, similarity of function and superficial resemblance of structures that have different origins. For example, the wings of a fly, a moth, and a bird are analogous because they developed independently as adaptations to a common function—flying.
Analogies are the result of convergent evolution. Interestingly, though bird and bat wings are analogous as wings, as forelimbs they are homologous. Birds and bats did not inherit wings from a common ancestor with wings, but they did inherit forelimbs from a common ancestor with forelimbs.
Convergent evolution is the independent evolution of similar features in species of different lineages. Convergent evolution creates analogous structures that have similar form or function but were not present in the last common ancestor of those groups. The cladistic term for the same phenomenon is homoplasy.
Hope this helps.
