Characteristics acquired during an organisms life are not passed on through genes

During a stud session about evolution one of your fellow students remarks "a giraffe stretched a snack while reaching for higher leafs, it's offspring inherited longer necks as a result." How can you correct the students misconception

The population me involved because of population bottleneck will cause chance fluctuations in allele frequencies.

A population of film crickets have heritable phenotypic variation for fast and slow chirp song. The frequency of alleles for both chirp types is 0.5. If hurricane Ida hit this population of field crickets and reduced the population by 80% which of the following is most likely over the next two generations

Over generations, human jaw and teeth have shrunk

An example that exhibits one of Darwins inferences

This describes an individual that is likely to be most successful in an evolutionary sense

An organism that dies after five days of life but leaves 10 offspring all of whom survived to reproduce

A particular gene of interest is not undergoing any Mechanisms of evolution

Imagine you predict a particular frequency for a genotype based upon detailed knowledge of that genotype frequency in population X of the species. Then use the hardy Weinberg model you find that the observed genotype frequency in a different population named Y of the same species is not significantly different from what you predicted or expected based on population X. Which of the following should you conclude?

Island forms in mainland forms descended from a common ancestor

It has been observed that organisms on islands are different from, but closely related to, similar forms found on the nearest continent

Adaptation

The bill morphologically of Darwins finches are prime example of

It must lead to a testable prediction

What makes a good hypothesis

A male clown fish change sex when the dominant female dies

Which of the following examples does not provide evidence for the evolutionary patterns of unity and diversity of life? -A male clown fish change of sex when the dominant female dies -Sharks and raise both have cartilaginous skeletons inherited from a common ancestor -fossilized skulls of the neanderthal support the idea that the Neanderthals are closely related to modern humans

Heritable phenotypic variation among individuals

Which of the following must exist in a population before natural selection can act upon that population

The features of meiosis

Which of these is most likely a contributor to human heritable traits variation from one generation to the next

If turtles use solar radiation to heat themselves, then I will observe more turtle sitting on logs for longer when the mean daily temperature is low

You observe a turtle sitting on a log in the full sunlight... Give me a prediction for that
