Answer:
One mRNA.
Explanation:
In bacteria, genes which are related to each other are found in cluster on the chromosome and mostly transcribed in a single unit from one promoter.
There are three genes present in lac operon which are lac Z, lac Y, and lac A. Under the control of one promoter, these genes transcribed in a single mRNA.
Then mRNA translated into proteins which help in utilization of lactose.
Phospholipid Bilayer. The simple or basic building blocks of a cell membrane are phospholipids. Phospholipids contain a hydrophobic end, which is insoluble in water, made up of two fatty acid chains of nonpolar molecules such as carbons and hydrogens. The other end is hydrophilic, which is soluble in water, and contains polar phosphate molecules.
The answer is air or water <span>currents and other organisms.
The non-motile protists cannot move independently. Motile protists use </span>cytoplasmic projections or cilia and flagella made of microtubules, but non-motile protists must rely on air or water <span>currents and other organisms in order to change their location.</span>
