A population of insects is sprayed with a new insecticide. Most of the

Biology
1 answer:
zepelin [54]2 years ago
4 0

Answer: This shows that over time, some insects can become "pesticide-resistant" meaning that pesticides don't affect them anymore. And this only happens every few generations. Therefore, each generation is being naturally selected and accumulating variations that make them resist the chemicals. This shows that each cockroach's genes are changing to give them variation from the rest of the population.

I hope this helps!

kolezko [41]

Answer:

  • Random dispersion occurs with dandelion and other plants that have wind-dispersed seeds that germinate wherever they happen to fall in a favorable environment.
  • Clumped dispersion is seen in plants that drop their seeds straight to the ground, such as oak trees, or animals that live in groups, such as schools of fish or herds of elephants.
  • Clumped dispersions may also result from habitat heterogeneity. If favorable conditions are localized, organisms will tend to clump around those, such as lions around a watering hole.

A species of fly has two alleles for the length of their legs. The allele for long
stira [4]

Answer:

According to Hardy Weinberg law (p+q)2=1 where p is fequency of one allele and q is the frequency of another allele.

According the question

 q represent the short legs and 33 of 100 organism have short legs.

   As a result the frequency of q with respect to the 100 organism is 33/100

                                                                                                                  =0.33

Therefore q=0.33

 we all know that

            (p+q)2=1

             ∴  p+q= 1

             ∴  p=1-q

               p= 1-0.33

                   p=0.67

The frequency of p is 0.67
