This is defined as a type of solution which has a large amount of particles which are dissolved thereby making it have a high concentration.

High concentrations of salt applied to the outside of the meat means it is hypertonic and therefore causes the bacteria to shrink because water molecule leaves the cells thereby destroying their structure preventing metabolic reactions from occurring which leads to their death.

G you extracted your dna from cheek cells. the concentration of your dna sample is 250 ng/μl. the dna template for pcr should be

Karo-lina-s [1.5K]

You should mix 4µl of DNA sample and complete it with 96µl (100-4) of water.

You can figure this out by using C1.V1 = C2.V2
C1 = 250 <span>ng/μl (Sample Concentration)
</span>V1 = ? (the necessary volume to take from the DNA sample)
C2 = 10 <span>ng/μl (PCR concentration)
</span>V2 = 100 µl (total volume)

V1 = $\frac{C2 . V2}{C1}$ = $\frac{10 . 100}{250}$ = 4µl

For the water: 100µl (total volume) = 4µl + Water
Water volume = 96µl

Given the genotypes, what are the corresponding phenotypes? (Freckles or no-freckles)<br> 30 points!

Kisachek [45]

FF no freckles
Ff no freckles (F dominates over f so there are no freckles)
ff freckles
