None of these suspects
A speciation in which new species evolve from a single ancestral species while inhabiting the SAME geographic region.
Sympatric speciation
Allopatric speciation
Complex speciation
Divergent speciation
What is genetic drift?
the changes in allele frequencies (genes) ,in a population, happening due to random events/circumstances.
It is an example of primary succession
Genetic drift are different organisms in a population due to inherited traits from their parents
It is part of symbiotic relationships such as mutualism, commensalism, parasitism
Using this picture, which statement is correct?
differences between species is a result
use and disuse of body parts
variation and natural selection
Which of the following best describes how natural selection results in insects that are pesticide resistant?
When a pesticide is sprayed on a crop, a few insects survive. These insects happen to have a random mutation that makes them resistant to the pesticide. These insects survive and reproduce, eventually resulting in pesticide-resistant population.
When a pesticide is sprayed on a crop, the insects respond by mutating their DNA, making them resistant to the pesticide. Therefore, a pesticide resistant population evolves.
When a pesticide is sprayed on a crop, it causes mutations in the insect DNA. Some of these mutations make the insects pesticide-resistant. These insects now form a pesticide-resistant population.
When a pesticide is sprayed on a crop, it kills the insects, which allows a new species to migrate into the habitat. Some of these species are pesticide resistant, thus a new population of pesticide resistant insects appears.
If you take antibiotics only the resistant bacteria survive and the non-resistant bacteria die. This is an example of...
Resistance
Survival of the fittest
How antibiotics work
Antibiotic resistant bacteria can
Survive
Reproduce
Pass on the resistant gene to their offspring
All of the above
In which ways can genetic engineering can improve crops
Make them pest or drought resistant
Make them more nutritious
Make them larger
All answers are correct
Scientists believe that frogs and butterflies evolved from a common ancestor over millions of years. Which of the following offers the most direct support for this theory?
