Answer:
Euglena is a single celled organism. It belongs to Kingdom Protista. Euglena is a eukaryotic organism that exhibit characteristics of both plants and animals. Some species of Euglena are photoautotrophs like plants which means they have ability to trap sunlight to produce food by the process of photosynthesis. Whereas, some species are heterotrophs like animals which means they obtain food by feeding on other organisms.
If scientists remove all of the chloroplasts from a Euglena, it will not be able to perform photosynthesis because chloroplast is an organelle that contains light sensitive pigments named as chlorophyll. Chlorophyll traps light energy from sun. Sunlight energy, along with carbon dioxide and water produces food in the form of glucose in plants and other photoautotrophs.
The correct answer is archaea which is last choice above. It
is because archaea is a microbe in which they have the property of not
exhibiting any nucleus or an organelle which they are to be considered more to
be a bacteria because of it.
Chemical energy may be released during a chemical reaction, often in the form of heat; such reactions are called exothermic. Reactions that require an input of heat to proceed may store some of that energy as chemical energy in newly formed bonds.
True. Especially if you are a visual learner. The models help explain the world in a easier way. Words is another method teachers and people use. But models make it fun and more understanding
I've actually learned something similar recently so your best bet is to go with B.
