Answer:
The correct answer is option B, that is, promoter, operator, gene.
Explanation:
In a prokaryote, just in front of the operator, the promoter is located, and just in front of the structural genes, the operator is located. All these in combination give rise to an operon.
Any gene, which codes for an enzyme or a structural protein is termed as a structural gene, in the lac operon, a structural gene codes for three distinct kinds of enzymes. A short sequence of DNA is situated just in front of the structural gene, which is known as the operator. An operator functions as a switch for transcription, that is, it monitors whether the process of transcription will take place or not.
Just in front of an operator, a sequence of a promoter is present, and for the transcription and translation of all the structural genes, the RNA polymerase needs to combine first with the promoter. In case, if no transcription is to take place, then the operator allows the repressor to bind with it and prevent the attachment of RNA polymerase with the promoter. Hence, the correct sequence of a prokaryotic operon is a promoter, operator, and gene.
Heat, light, sound and fire may have been involved when the Bunsen burner was lit with the spark from the Van de Graaff generator. Bunsen burner is a common device in the lab.
<h3>What is a Bunsen burner?</h3>
Bunsen burner is a laboratory device (gas burner) that generates a single open gas flame.
The gas most commonly used in Bunsen burner is generally natural gas, i.e., methane gas.
This device (Bunsen burner) can be used to generate a heat source during a lab experiment.

Answer: see explanation
Explanation:
A. substrate
B. Active site
C. Enzyme binds with substrate
D. Active site of enzyme
E. Products leaving active site
Simplified enzymatic reaction. The substrate reversibly binds to the active site of the enzyme, forming the enzyme-substrate (ES) complex. The bound substrate is converted to product by catalytic groups in the active site, forming the enzyme-product complex (EP). The bound products are released, returning the enzyme to its unbound form, ready to catalyze another round of converting substrate to product.
The huckleberry patches will provide a very high level of consumption efficiency.
<h3>What is consumption efficiency?</h3>
Consumption efficiency refers to the ability of a consumer to be able to derive the maximum level of consumption from a given resource or group of resources.
The huckleberries depend on the animals such as Bears as well as other herbivores for seed dispersal and propagation. These plants have therefore, develop efficient means to encourage dispersal by these animals. The seeds of the Huckleberries are enveloped in sweet, nutritious fruit that is comparatively undefended.
Therefore, the Bears and other herbivores will derive a very high level of consumption efficiency from the Huckleberry patches.
In conclusion, consumption efficiency measures the ability of a consumer to derive maximum consumption. High consumption efficiency implies that the resource provides a great deal of benefit and satisfaction to the consumer.

The longest day of the year isn't the hottest day of the year because the phenomenon of the hottest weather following the summer solstice by a month or two is called the lag of seasons.
