Ethan has been eating salads without first washing the lettuce. He risks ingesting E-Coli and Salmonella bacteria.

  • You could inhale dangerous bacteria from the soil or pesticides used on the produce in the fields if you eat unwashed produce. Furthermore, it's possible that you'll consume bugs that were collected with the produce.
  • Animal-based foods like meat, poultry, eggs, dairy products, and shellfish are frequently the cause of food poisoning in humans.
  • Fruits, vegetables, and other raw foods, however, can potentially be polluted and sicken people if they aren't rinsed beforehand.
  • Fruits and vegetables that are the safest are cooked; those that are the next-safest are washed.
  • Prevent eating unwashed fresh food. Fresh produce has many health benefits, but eating raw fruits and vegetables occasionally puts you at risk for food poisoning from pathogens including Salmonella, E. coli, and Listeria.

A farmer plants Bt cotton that is genetically modified to produce its own insecticide. Of the cotton bollworms feeding on these
-Dominant- [34]

Answer:

the frequency of the resistant allele after one generation is 0.989

Explanation:

Given that :

A farmer plants Bt cotton that is genetically modified to produce its own insecticide.

Of the cotton bollworms feeding on these Bt plants, only 5% survive

i.e the survival rate s  = 5% =0.05

unless they have at least one copy of the dominant resistance allele R that confers resistance to the Bt insecticide

Frequency of R allele = 0.01

In order to determine what will the frequency of the resistance allele be after one generation of cotton bollworms fed on Bt cotton; we need to first determine the frequency of the recessive allele r.

According to Hardy-Weinberg Equilibrium ;

p+q = 1

Let p = R and q = r

R + r = 1

0.01 + r = 1

r = 1 - 0.01

r = 0.99

Now; the  frequency of the resistance allele after one generation can be calculated as :

q' = \dfrac{q(1-sq)}{1-(sq^2)}

where ;

q' = R

q = r

q' = \dfrac{0.99(1-(0.05 \times 0.99))}{1-(0.05 \times 0.99^2)}

q' = \dfrac{0.99(0.9505)}{1-(0.049005)}

q' = \dfrac{0.940995}{0.950995}

q' = 0.989

Thus; the frequency of the resistant allele after one generation is 0.989

Organic sediment on lake bottoms and the ocean floor is broken down by microbes into inorganic forms of phosphorous in a process
murzikaleks [220]

Answer: Mineralization

Explanation: Phosphorous cycle moves through the rocks, water, soil, sediments and organisms.

The weathering of rock releases phosphate ions and other minerals. Plants take up the phosphate from the soil. Phosphorous is present in the form of organic phosphate which is broken down by the help of microorganism in the form of inorganic phosphate.

This process is known as mineralization.
