Once pollen lands on the stigma of a flower, the pollen germinates, creating a pollen tube that grows down the ovule. The sperm cell moves through the tube to fertilize the egg. Based on the evidence from the experiment above, explain how natural selection might have led to directional selection toward higher aperture number.

If a person scatters a handful of plant seeds from one species in an area, how would natural selection work in this situation?
Flowers whose throats (nectaries) are too long for hummingbirds to reach their nectar are unlikely to be pollinated (nectar reward isn't available) and therefore the flower is unlikely to reproduce. But if the nectaries are too short, hummingbirds can get their nectar without pollinating them because they don't reach in far enough to touch the pollen-carrying anthers, thus no reproduction for the flower. Flowers evolve with an intermediate length of nectaries. This is an example of what sort of selection? Group of answer choices Disruptive Stabilizing Directional Sexual
According to Darwin, why do certain traits become more common in a population over time? (Hint- consider why dome-shaped tortoises are found in Isabella Island but not in Hood Island)
In your own words, describe why the orange beetles survived in relationship to what you have learned about natural selection.
Darwin's concept of evolution "the theory of decent with modification through variation and natural selection" can best be demonstrated by which of the following examples? a. A giraffe stretches his neck to reach higher branches. The exercise of stretching up strengthens the muscles in the giraffe's neck and legs. This ability to stretch is also seen in the giraffe's offspring. b. A monkey accidentally drops her fruit in the salty water of a bay. She recovers the fruit and eats it. She discovers the fruit is cleaner and tastes better after it has been in the salty water. She continues to wash the fruit in the bay before eating it. Her offspring see what she has done and also wash their fruit in the salty water. Soon, the whole population of monkeys is washing their fruit. c. Several turtles hatch from a clutch of eggs buried in the sand on a beach. One of the turtles is the color of the sand; the others are darker in color. The turtles scurry toward the water,…
It is believed that trichomes give an evolutionary advantage to plants when herbivory is high because the trichomes may be irritating to the animals that feed on these plants. In these situations, the selection pressure would favor plants with more trichomes. The experiment described above mimics this condition. What type of selection is represented here? A. Stabilizing B. Disruptive C. Directional selection
Using Darwin's theory of Natural Selection write a paragraph which explains why resistance to herbicides has evolved in the pigweed plant. Your answer must include the following terms. Please put your terms in bold text for ease of reading. Individual variation Differential survival
What Darwin Never Knew. List all ways you can think of observations from nature ,development,etc that were important for Darwin when he developed his theory of evolution by natural selection. Why are the Galápagos Islands unusual? How were they significant for the formation of Darwin’s theory ? Why were the finches important to Darwin theory ? Why did the beaks of the finches look different?
In the US, many farmers regularly use the herbicide glyphosate to keep their fields free from weeds. Now, however, they are reporting the presence and spread of superweeds which are resistant to the said herbicide. Give a brief explanation of this using what you learned about natural selection (Modified from Hoefnagels,2016)
Some worms eat at night (meaning they are nocturnal) and some worms eat during the day (meaning they are diurnal.) Most birds eat only during the day, so they are only eating diurnal worms, due to the fact that the nocturnal worms are burrowing during this time. Each spring when the worms reproduce about 500 offspring are born but only 100 of them live long enough to reproduce themselves. Explain how natural selection will occur and include the 4 principals of natural selection.
During drought years on the Galapagos, small, easily eaten seeds become rare leaving only large, hard-cased seeds that only birds with large beaks can eat. If the drought persists for several years, then what should one expect to result from natural selection? Explain your reasoning based on the postulates of the Darvin natural selection theory.
What Darwin never knew . What did Darwin notice during his study of embryos? How did this influence his theory? How did artificial selection influence Darwin’s theory? During the time of Darwin how were the prevailing views of how species were created /behaved different from Darwin’s observations of nature?
