Answer:
The correct answer is option B, that is, promoter, operator, gene.
Explanation:
In a prokaryote, just in front of the operator, the promoter is located, and just in front of the structural genes, the operator is located. All these in combination give rise to an operon.
Any gene, which codes for an enzyme or a structural protein is termed as a structural gene, in the lac operon, a structural gene codes for three distinct kinds of enzymes. A short sequence of DNA is situated just in front of the structural gene, which is known as the operator. An operator functions as a switch for transcription, that is, it monitors whether the process of transcription will take place or not.
Just in front of an operator, a sequence of a promoter is present, and for the transcription and translation of all the structural genes, the RNA polymerase needs to combine first with the promoter. In case, if no transcription is to take place, then the operator allows the repressor to bind with it and prevent the attachment of RNA polymerase with the promoter. Hence, the correct sequence of a prokaryotic operon is a promoter, operator, and gene.
I believe it would be the reptile kingdom!
The correct answer to your question is B. Glycine-Tyrosine-Glycine-Histidine-Histidine.
You can find this by taking groups of codons starting with the first group (GGC). GGC is located under Glycine so Glycine will therfore be an amino acid found in the protein. Continue doing this with the next codons to come up with the answer.
I hope this isn't too late and still helps!

Answer:
Biotic: Plants
Abotic: Rocks
Explanation:
A biotic factor is something in an ecosystem or environment that is living. Some examples that could be found in a park are grass, flowers, trees, squirrels, pigeons, fish or people.
An abiotic factor is the exact opposite of a biotic factor: something in an ecosystem or environment that is not alive. Some examples that may be found in a city park include a park bench, a trash can, rocks, a playground, a pool, basketball court, temperature, and humidity.
Answer:
The fight-or-flight-or-freeze or the fight-flight response (also called hyperarousal or the acute stress response) is a physiological reaction that occurs in response to a perceived harmful event, attack, or threat to survival.
