The lac operon consists of a coding region, which contains three genes that code for proteins needed to metabolize lactose, and a regulatory region, which regulates transcription of the coding region. a. True
b. False

True.

Explanation:

The lac operon consists of a coding region, which contains three genes that code for proteins needed to metabolize lactose, and a regulatory region, which regulates transcription of the coding region because The lac operon comprises of a coding region, that is made up of three genes . These genes code for proteins that is needed to metabolize lactose, and a regulatory region, which help to regulate transcription of the coding region.

The three enzymes are lacZ, lacY, and lacA . LacZ is responsible for encodinv an enzyme called β-galactosidase, which help to digest lactose and break it into two constituent sugars: glucose and galactose. lacY is a permease which move lactose into the cell.

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.

idk what the options are but

these is a strong electrostatic attraction between the ions hence a lot of energy is needed to overcome this attraction

this is why the boiling points are so high
