Answer:
The correct answer is a. domain Eukarya.
Explanation:
Bacteria archaea and eukarya are considered as the three domains of life. Bacteria and eukarya lack a membrane-bound nucleus and other membrane bound organelle therefore they are considered in prokaryotes and organisms having membrane-bound nucleus comes under domain eukarya.
So the organism which have eukaryotic cell comes under domain eukarya. These organisms can be single cellular or multicellular and their genetic material is packed in a double membranous structure called the nucleus. So the correct answer is a. Eukarya.
<u>Answer</u>:
- The term refrigerate once opened is found in preserved foods (canned or processed) and this basically means to cool the container after opening it along with its contents.
- The rationale behind this is that once the container gets opened for consumption, it is immediately exposed to the oxygen present in the atmosphere and the dust particles.
- Further, the contents are also exposed to the various bacteria and mold spores present in the environment. Due to such exposure, all protection offered by canning and processing the food is lost.
- It is important to know that when the contents are kept at room temperature, the mold and bacteria start growing immediately and multiplying in number and this leads to the degradation of the food product as well as toxicity.
Therefore, it is important to refrigerate the contents as cooler temperatures <em>slows the growth of these microorganisms and inactivates them</em>. Thus, increasing the shelf life of the food.
