Choose the correct sequence of the prokaryotic operon. A) gene, operator, promoter B) promoter, operator, gene C) operator, promoter, gene D) operator, gene, promoter
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.

B. The reptile species produces few offspring with some unique traits, and the vegetation remains constant.
C. The reptile species produces few offspring with no unique traits, and the vegetation changes quickly.
D. The reptile species produces many offspring with some unique traits, and the vegetation changes slowly.
Answer:
i think its b
Explanation:
Final answer:
Option C, where the reptile species produces few offspring with no unique traits, and the vegetation changes quickly, would most likely result in the extinction of the reptile species over a period of twenty thousand years.
Explanation:
The most likely scenario that would result in the extinction of the reptile species over a period of twenty thousand years is option C. This is because if the reptile species produces few offspring with no unique traits, and the vegetation changes quickly, the species will not have the ability to adapt to the new environment and may struggle to find enough food to survive.
Without the ability to adapt and thrive in the changing vegetation, the reptile species would likely face extinction over time.

What happens when molecules diffuse across the cell membrane? The molecules diffuse until all of them are outside the cell. The molecules move from areas of low concentration to high concentration. The molecules move from areas of high concentration to low concentration. The molecules diffuse until all of them are inside the cell.
Answer: The correct answer is from areas of high concentration to low concentration.
Explanation: Diffusion, by definition, is the process of molecules (any molecule) going down their concentration gradient (i.e. they are going from higher concentration to lower concentration). Hope that helped!
When molecules diffuse across the cell membrane, molecules move from areas of high concentration to low concentration.
Diffusion of molecules?In facilitated diffusion, molecules diffuse across the plasma membrane with the help of membrane proteins such as channels and carrier proteins. The concentration gradient of these molecules exists, so they have the potential to diffuse into (or out of) the cell.
With this information, we can conclude that when molecules diffuse across the cell membrane, molecules move from areas of high concentration to low concentration.
