Answer:

a. the coordinated control of gene expression in bacteria

Explanation:

An operon in bacteria is a collection/cluster of genes that are under the control of a single promoter. It includes 3 components: a promoter, the genes and an operator. The operator is where a repressor binds, and the promoter is where transcription begins.

Operons allow organisms to control the expression of multiple genes in response to environmental cues

When frying an egg, the protein albumin denatures and maintains only its ________ structure?
S_A_V [24]
When frying an egg, the protein albumin denatures and maintains only its primary structure. The simplest level of protein structure is the primary structure which is simply the sequence of amino acids in a polypeptide chain. The order of a protein is resolute by the DNA of the gene that encrypts the protein or that encodes a portion of the protein, for multi-subunit proteins. An alteration in the DNA of the gene sequence may principal to an alteration in the amino acid order of the protein. Even altering just one amino acid in a sequence of a protein can affect the protein general assembly and purpose.

Rus_ich [418]

Answer:

The correct answer is option B, that is, less genetic diversity in later generations.

Explanation:

A pandemic that spread across Europe between 1348 and 1350 was named as the Black Death. It has been predicted that of the total population of Europe at that time 30 to 60 percent died due to the pandemic. The geneticists are still trying to document the influence of Black Death on the population of Europe today.  

It has been found that in England, the genetic diversity is found much lower in comparison to what it was in the eleventh century, and is primarily due to so many people dying in the 1300s. However, the rest of Europe does not demonstrate a dropped amount of genetic variation, which maybe because of the enhanced patterns of migration in other places.

Which of the following terms are NOT used interchangeably? muscle tension - muscle force in vivo - in the body/ the living muscl
Karo-lina-s [1.5K]

Answer:

The correct answer is "motor unit - motor neuron".

Explanation:

Motor unit and motor neuron are related terms, however they could not be used interchangeably because a motor unit is not comprised only of a motor neuron. A motor unit is made of a motor neuron, skeletal muscle fibers and neuron's axonal terminals. Therefore motor unit is a more broadly term, and is referred to the units that coordinate the contractions of single muscles.
