Yes the following statements about her trout is likely true Because the ponds are different and the populations are likely to experience different mutations, the populations will likely diverge evolutionarily, but only over many generations.
Explanation:
The effect of genetic drift can be seen in all populations but the most is seen in small population. The change in allele frequency due to the sampling error would lead to evolution of the species.
Bottleneck effect is when a population gets reduced due to some natural disaster. Her friends were not right about bottleneck effect.
So it is clear that no bottleneck effect will occur as each pond have different chance or rate of mutation and the change in alleles will be different. The trouts will evolve independently in the different ponds and pass on the traits to their progeny.
Genetic drift does not take into account for the harm or benefit of the alleles that are passed on.
Answer:
I think that birds have different bill lengths because of their habitats and their diet. Also natural selection and evolution has also played a factor due to the fact that birds have not always looked the way that they do now, for example the Archaeopteryx a bird that lived around the time of the dinosaurs had a shorter and more powerful bill to grind insects and small mammals
Explanation:
Answer:
In a research there are two variables independent and dependent variable. independent variable is defined as the variable which is controlled and changed in a scientific experiment and evaluate the effects on the dependent variable while the variable which are tested and measured in experiment are called dependent variable.
When antibiotic is sprayed at one side of the petri dish, the bacterial growth on that side will eventually decrease in comparison to other side.
So, the independent variable in this experiment will be antibiotic because it is used to understand the growth of bacteria by decreasing their numbers and the dependent variable in this experiment will be bacteria as they vary according to the change in independent variable that is antibiotic.
A successful food web needs to have all of the organisms mostly bigger than the ones that they are eating otherwise the food web wouldnt neccessarily work properly and then the food webs would all be messed up.
