Homeostasis is <span>the body's tendency to maintain relatively stable internal conditions in spite of greater changes in its external environment. It is a process in which all body cells are involved and through which the body systems stays stable and keeps constant internal environment. Homeostasis enables the body to maintain its balance and stability. </span>

Answer: Homestasis

Maintaining blood temperature is one of homeostasis example. Mamalia is an animal group called warm-blood because their body temperature is maintained. By keeping the body temperature stable, the enzyme used in the body can work in optimal temperature. That makes them use energy more efficiently.

The lactose (lac) operon in E. coli is an example of a repressed gene when lactose is not available in a cell. In 3-5 sentences
irakobra [83]

Answer:

Please find the detailed explanation of this statement below

Explanation:

Firstly, a repressed gene is a gene whose expression has been inhibited or repressed. The lac operon in E.coli bacteria is a regulatory unit containing structural genes, a single promoter and operator regions. The promoter is the region where the transcription enzyme (RNA polymerase) binds to in order to transcribe the genes in the lac operon. The structural genes in the lac operon can only be expressed in the presence of lactose sugar.

However, in the absence of lactose, LAC REPRESSOR, which is a transcription factor (protein), prevents the binding of RNA polymerase to the PROMOTER region by binding to the OPERATOR region of the lac operon. This inhibits the expression of the lactose genes in the operon.

Note that, the structural genes in the lac operon (lacZ, lacY, lacA) code for proteins that help break down lactose sugar for energy in the E.coli bacteria. Therefore, a bacteria cell with a repressed lac operon will be unable to degrade lactose sugar.
