Answer:
Euglena have diversed nutritional requirements. They are autotrophic when kept in light and heterotrophic when deprived of light.
The Euglena contains chloroplast in it to perform photosynthesis in the presence of light.
When the Euglena is kept in the dark it starts deriving energy from the organic matter around it and shows heterotrophic mode of nutrition.
When light will be provided to Euglena it will start resynthesizes its photosynthetic pigment and it will start perform photosynthesis.
Re-exposure of Euglena to light after chloroplast destruction will not restore photosynthesis; instead, Euglena will continue to survive as a heterotroph until it possibly re-acquires chloroplasts through secondary endosymbiosis or other means.
When Euglena, a microbial eukaryote, is deprived of light and its chloroplasts are destroyed, reintroducing it to light will not prompt the immediate restoration of photosynthesis. Having lost their chloroplasts, they cannot simply regrow them upon exposure to light. Instead, Euglena will rely on its ability to behave as a heterotroph, acquiring nutrients and energy by ingesting or absorbing organic matter from its environment. Euglena is known as a mixotroph, which means it can switch between autotrophic (photosynthesizing) and heterotrophic lifestyles, depending on the available resources. Euglena stores energy in a glucose polymer different from typical starch, and this storage, along with other nutrients absorbed from the environment, can support them when photosynthetic capability is compromised.

Answer: flows through wires of flashlight.
Explanation: When the flashlight is turned on, the chemical energy stored in batteries is converted into electrical energy that flows through wires of flof the flashlightshlight. This electrical energy is then transformed first into heat energy and then light energy.
Answer:
A few isolated features of the stimulus.
Explanation:
Eliminate
B) plants.
C) the sun.
D) rodents.
Answer:
The correct answer is option D, rodents
Explanation:
Eagle is carnivore thus it feed on flesh of other animals. Thus among all the given options flesh can be obtained from rodents only. However the common diet of eagle includes mammal of sizes varying from small to medium. Mammals like squirrels, raccoons and rabbits are among the common diet of eagle. However, some eagle also feed on bird and fishes.

Answer;
To protect the rest of the esophagus from sharp food particles and stomach acid.
Explanation;
The mucosa is the innermost layer, and functions in absorption and secretion. It is composed of epithelium cells and a thin connective tissue.
It contains specialized goblet cells that secrete sticky mucus throughout the GI tract, that prevents the corrosion of the stomach walls and esophagus from sharp food particles and the acids from the stomach.
