Which is an example of genetic drift?
A. Artificial selection creates vegetables resistant to insects.
B. Allele frequencies change randomly each generation.
C. Females choose mates, resulting in large males.
D. Polygenic traits change due to directional selection.
Answer:
i think the answer is b
Explanation:
B. Allele frequencies change randomly each generation
Answer:
B
Explanation:
Genetic drift is the alteration of different genotypes in a small population which can cause individuals and organisms getting wiped out, not being able to reproduce, and disappearance. Allele frequencies change randomly each generation in a gene pool (collection of different genes present in a particular population: species in this gene pool have a choice to leave the gene pool or die out).

Answer:
alright bet I got this
Explanation:
Have you ever wondered what can happen to those plastic bottles you toss away? How do they decompose? What happens to them? Its simple really, they get eaten! No, not by people of course they are eaten by a tiny critter called a wax worm. The wax worms earn their name because they are often found living in beehives where they eat the beeswax.
Wax worms much like mealworms are used to break down things that would normally be endangering to our environment. These seemingly useless little animals do a whole lot for our environment especially with the amount of waste we produce! They really are a tiny secret hero to todays pollution problem.
After quite a few studies scientists are still unsure on how was worms can breakdown plastic with their tiny bodies but they appreciate the work these little recyclers do. They have a lot of theories on how these worms do this one of the theories is that bacteria can break it down, another theory is that enzymes in the worms intestines break down plastics. Though scientists believe it will take a while to figure this out they enjoy studying and learning more about this tiny helper.

Which organism are primary consumer in this food web?
Beavertail cactus
:-- they are primary consumer because they produce the material and store the energy at the bottom of the food chain. In other words, all animals are dependent, either directly or indirectly on the food materials stored in plants.
It is necessary to have limitations in an environment because if not:
Traits from species would get crossed.
Water and shelter would be automatically created by extra species that are new.
The populations of the world would soon crowd one another out and make conditions unlivable.
The world would balance itself out without problems.
animals.
Plants would take over the space of animals
Best guess is "The populations of the world would soon crowd one another out and make conditions unlivable."
witch best describs the theroy of evlotion
Charles Darwin’s theory of evolution states that evolution occurs by natural selection. Individuals in a species shows variation in physical characteristics. This variation is because of the differences in their genes.
What is evolution?Evolution is the process by which species adapt over time in response to their changing environment.
Individuals with characteristics best match to their environment are more likely to survive, finding food, avoiding predators and resisting disease. These individuals are more likely to reproduce and pass their genes on to their children.
