The right answer is sea star living deep in the ocean

In general, the majority of starfish species live in temperate or cold waters (including under pack ice and in the deep sea). Several families are subservient to the abyss like Freyellidae and Brisingidae, which are found up to 6,000 m deep.

The starfish has no real ability to regulate its temperature. The only option he has for this is to amputate a limb to reduce its internal temperature. But since in this case we speak of starfish living deep in the ocean, the animal will not have to resort to this option.

Further Explanation: Endotherms Endotherms are animals that can control their internal body temperature. Their body temperature is normally warmer than the temperature of the environment and remains constant. They are also known as warm-blooded animals. They include mammals and birds. Mammals and birds have a body temperature that remains constant irrespective of the temperature in their environment. Endotherms have adaptations to help them regulate their body temeperature for example, sweat glands keeps them cool, fur and feathers which helps endotherms to stay warm. EctothermsEctotherms are animals whose temperature vary depending on the surrounding or environment. In other words, their body temperatures are the same or close to the temperature of their environment, such that when the environment is cold then the animal must move to a warmer place. They include, reptiles, amphibians, and fishes. Ectotherms are therefore more limited in their choice of environment because they are dependent on the environmental temperature. Ectotherms depend on their behavior to regulate their body temperature such that they have to move their bodies into the shade or sun to cool down or warm up. A sea star is an example of an ectotherm whose body temperature is determined by its environment

transcription is a process in which information is rewritten. it is something our cells must do, in a more specialized and narrowly defined way. in biology, transcription is the process of copying out the dna sequence of a gene in the similar alphabet of rna. it needs to happen in the nucleus because that's where the dna is. dna is always inside the nucleus unless the cell is dividing.

transcription is the first step in gene expression, which involves copying a gene's dna sequence to make an rna molecule. transcription is performed by rna polymerases. it has three stages: initiation, elongation, and termination. rna molecules must be processed after transcription in eukaryotes.

explanation:

long version:

the protein synthesis consists two processes which are, transcription and translation. transcription takes place in the nucleus. it uses dna as a template to make an rna molecule. rna then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. transcription is the first part of the central dogma of molecular biology: dna → rna. it is the transfer of genetic instructions in dna to messenger rna (mrna). during transcription, a strand of mrna is made that is complementary to a strand of dna.

these three stages are:

initiation: in which is the beginning of transcription.occuring when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

elongation: in which is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

termination: in which is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
