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
The probability of the female child of Charles and Marie suffering from hemophilia is 50% or 0.5.
<h3>What is the probability of hemophilia?</h3>
Hemophilia is a disease that is linked to the X-chromosome.
The probability of having female who suffers from hemophilia depends on the genotype of the parents.
Assuming that the genotype of the parents are as follows:
Father: XcY --> hemophilic
Mother: XXc --> carrier
A cross between the parents will produce two female offspring with genotypes, XcXc and XXc.
Therefore, the probability of the female child of Charles and Marie suffering from hemophilia is 50% or 0.5.

The answer that apply is:
<span>They carry energy
</span><span>They travel from the epicenter.
</span><span>They vibrate throughout the lithosphere.
</span>
Reason why the following the false:
<span>They move in one direction- seismic wave do not only move in a direction but spread out through the plate,that's why a large area would be affected.
</span><span>They are produced by earthquakes. - seismic waves are not produced by earthquake but the opposite,earthquake occurs due to the release of seismic wave when the ground break and vibrates.</span>
