Answer: Cooking chicken to at least 165°F makes the chicken safe to eat.
Explanation: This kills all of the bacteria in the meat, leaving it safe to eat.
If you don't fully cook the chicken to at least 165°F, you may eat harmful bacteria which can cause unpleasant illnesses such as Salmonella.
It is advised to follow safe food handling practices.
Maybe, mosquitoes lay eggs in still water like a in pail or bucket
Answer:When two true breeding plants breed they produce an F1 generation. The genotype for the true breeding parents would be TT and tt. Each of the offspring in the F1 generation would have the genotype of Tt and would have the phenotype of being tall, since tall is dominant. Next, we breed the plants of the F1 generation to produce the F2 generation. We know that the phenotype of the parents are both Tt. From this you can create a punnet square:
T t
T TT Tt
t Tt tt
Explanation:TT is expressed as tall
Tt is expressed as tall
tt is expressed as short
The punnet square shows you that 75% would be tall and 25% would be short.
The 200 short plants in the questions would be 25% of 800. Take the 200 away from 800 and you get approximately 600 that would be tall.
Answer:
to add nucleotides to a DNA primer
Explanation:
The Polymerase Chain Reaction (PCR) is a technique widely used in molecular biology in order to amplify small segments of DNA (100 to 1000 bases). PCR uses a thermostable DNA Taq polymerase that adds nucleotides to the DNA template at the position specified by short single-stranded DNA primers that bind to this template by complementary base pairing during the annealing phase of the PCR cycle. Subsequently, the DNA polymerase adds deoxynucleotide triphosphates (dNTPs) to the opposite DNA strand, this phase of the PCR cycle is known as the elongation phase. Finally, the resulting double-stranded DNA fragment is separated by heat during the denaturation step and this 3-step PCR cycle is repeated many times to amplify the target DNA region.
