Explanation:
The lac operon is encodes multiple enzymes which catabolize lactose, for example beta-galactosidase
<h3>What is an operon?</h3>
An operon is a cluster of genes that are transcribed together to give a single messenger RNA (mRNA) molecule which which is used for the synthesis of multiple proteins.
An example of an operon is lac operon.

Answer:
meiosis you will have four haploid cells (half the number of chromosomes is a diploid cell) and after mitosis you will have two diploid cells
Explanation:
Mitosis you begin with a parent cell that is haploid, it copies all it's chromosomes and splits so each daughter cell have the same number of chromosomes as the parent cell so both being diploid
In meiosis the chromosomes fold over DNA and are put in pairs, in the first division the pairs are split up evenly into two cells randomly (diploid still) but the the cells split the chromosomes in half in them creating four grneticly different haploid cells
A biotic factor is a living thing that has an impact on another population of living things or on the environment. Abiotic factors do the same thing, but they are non-living. Together, biotic and abiotic factors make up an ecosystem. To survive, biotic factors need abiotic factors.
