as insects became exposed to pyrethroids, toxicity of pyrethroids weakened over time. which means that Most insects had the allele for pyrethroid resistance, but it remained masked. The allele for said pyrethroid resistance, evidently increased throughout the population.
has this helped?
<em>A. 11.0 L is the researcher's volume measurement to the SL units of liter</em>
<u>Explanation:</u>
Given that a researcher recorded that the chemical reaction has water = 2.90 gallon.
We have to convert the researcher's volume into the SL units of liter.
<em>So, we know that 1 gallon = 3.875 liters</em>.
Then we have to convert 2.90 gallons of water in to liters.
Then , volume in L =
= 
= 
<em>Then the required volume in 
</em>
I believe he is looking for an allele
An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosomes. Humans are called diploid organisms because they have two alleles at each genetic locus, with one allele inherited from each parent.
