Answer:
Meiosis
Explanation:
Gene recombination refers to the mixture of genes from different individuals that occurs during sexual reproduction. Gene recombination is responsible for mixing between genes, which results in genetic variation in a bacterial population.
Genetic variability in a bacterial population occurs through three types of mechanisms: transformation, conjugation and transduction. However this genetic variation does not occur through Meiosis.
Transformation is the incorporation of free DNA by the bacterial cell. Conjugation is the process of transferring DNA from one bacterium to another, involving contact between the two cells. Transduction is the transfer of genetic material between cells, mediated by bacteriophages.
Answer:
It is usually associated with physical growth delays, mild to moderate intellectual disability, and characteristic facial features. The average IQ of a young adult with Down syndrome is 50, equivalent to the mental ability of an eight- or nine-year-old child, but this can vary widely.
Symptoms: Delayed physical growth, characteristic facial features, mild to moderate i...
Other names: Down's syndrome, Down's, trisomy 21

Answer:</h2>
<h3>In a fat molecule, the fatty acids are attached to each of the three carbons of the glycerol molecule with an ester bond through the oxygen atom. During the ester bond formation, three molecules are released. Since fats consist of three fatty acids and a glycerol, they are also called triacylglycerols or triglycerides.</h3>
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>
1). Thus, the syndrome is typically more severe in males because males have only one X chromosome, while females have two. It is unclear how changes (mutations) in the DNA structure of the gene lead to the clinical findings. There is no cure and no standard course of treatment for Coffin-Lowry syndrome.
