The right answer is the promoter.
• The promoter is a nucleotide sequence that allows the transcription of the gene into mRNA. It is recognized by the RNA polymerase that initiates transcription. During the synthesis of the RNA, the promoter indicates which gene must be expressed and therefore which proteins the cell must produce. In an operon it is common to all genes.
• The operator is a segment of DNA and / or messenger RNA to which a chemical signal (a regulatory molecule) binds. It can be either a repressor signal or a transcription activating signal (DNA operator) or translation (RNA operator) of the genes of the operon. The RNA polymerase does not recognize this structure.
Ozonosphere would be the answer because its basically asking what is the layer that protects earths radiation.
Answer and Explanation:
The plant cell has a cell wall, chloroplasts, plastids, and a central vacuole—structures not found in animal cells. Plant cells do not have lysosomes or centrosomes.
Answer:
One example of a harmful mutation is an animal's different coloring than others in its species. If a deer was albino, it would have a much harder time blending in, escaping predators and most likely have trouble finding a mate.
Explanation:
Answer:
Seed germination starts with imbibition when the seed takes in water from the soil. This triggers root growth to allow the seed to get more water. Then, the shoots develop and grow towards the sun above ground. After the shoots reach the ground, leaves form, allowing the plant to harvest energy from the sun.

I've taken lots of science classes in my day lol
Mostly bio
Anywho hope this helps :)
