Answer:
Phosphatidylcholine and phosphatidylserine
Explanation:
A reasonable conclusion supported by these observations is that the animal was endothermic and had a high metabolic rate.
<u>Explanation:</u>
With reference to warm-blooded species is preferred the endothermic are the species that preserve a steady body temperature regardless of the ambient temperature. Endothermic species mainly include animal kingdom birds and mammals. Many shrimp, however are endothermic too.
If a variation occurs, i.e. if the heat produced is less than the heat loss, the metabolic rate increases to compensate for that loss. Shivering is another method used by people and many other warm-blooded organisms to boost their body temperature. But in case the heat loss is smaller than the heat produced, the process of panting or suddening occurs to increase the heat loss.
The correct answer is: a. A site in DNA that recruits the RNA Polymerase
Promoters are regions of DNA molecule located near the transcription start codons of genes, usually upstream on the DNA with the function to initiate DNA transcription. Promoters contain specific DNA sequences (e.g. TATA boxes) that are binding sites for the enzyme RNA polymerase and transcription factors that recruit RNA polymerase. Transcription factors can regulate gene expression and act as activators or repressors depending on sequences that attach to specific promoters.
