Answer:

C) perspiration

Explanation:

Living organisms are characterized by certain processes they undergo. These processes makes them defined as living. Mollusks are a group of invertebrate animals that are often protected by hard shells. They undergo characteristics of living things like respiration (gaseous exchange), excretion (pass out waste substances) and even the circulation of fluid within their body system but they do not perspire.

In other words, animals of the mollusk group do not sweat or exude water from their skin because they do not possess sweat glands considering the fact that they are cold-blooded animals and externally regulate their temperature.

In eukaryotic cells, the message from the DNA must be removed from the nucleus before it can be read and used to make proteins.

Veronika [31]

Answer:

Protein production in prokaryotes begins even before the completion of transcription. This means that ribosomes attach to the mRNA being generated even before transcription process is terminated. Therefore translation occurs in concurrence with transcription. This is because there is no definitive boundary between the nucleoid and cytoplasm.

In eukaryotic cells, the nucleus is separated from the cytoplasm by the nuclear membrane. This means transcription has to complete before the translation of proteins occurs. This is because the ribosomes are located in the cytoplasm while the DNA is in the nucleus.

This difference is part of the reason prokaryotic cells are able to respond really fast to an environmental stimuli as compared to eukaryotes. Remember in addition mRNA in prokaryotes do not need splicing (as required in eukaryotes) adding to quick protein production.
