These specialized plant structures are often brightly colored, produce sweet nectar, and help plants transfer pollen from one flower to another, often with the help of animals.

A population of moth-pollinated flowers suddenly loses its main moth pollinator species. Using evidence and reasoning, explain how this could affect the plant’s reproductive success and what might happen to the population over time.
The plant’s reproductive success would likely decrease because fewer flowers would be pollinated. Over time, the plant population might decline unless another pollinator adapts to fill the role.

In cattle, the allele for solid coat color is dominant (R) and the allele for white-spotted coat is recessive (r). A rancher crossed two cows, both solid color. What combination of genes in the solid-coat parents could result in offspring with the white-spotted phenotype?

Two scientists are debating why a certain bird species has developed a unique dance during mating season. One claims it’s random behavior; the other argues it evolved to improve reproductive success. Using empirical evidence and reasoning, support the scientist you agree with.
Support the second scientist: The mating dance is a characteristic behavior that increases reproductive success by helping birds attract mates and ensure their genes are passed on. Evidence from many bird species (like peacocks or cranes) shows such behaviors are linked to higher mating rates.

Jeffrey is a carrier of the disease and has just found out that his wife, Shannon, is also a carrier. They are concerned about having a child with Tay Sachs. What is the probability that they will have a child with Tay Sachs?

Many plants can reproduce both sexually and asexually. For example, rose bushes reproduce asexually when cuttings planted in the ground grow roots and become a new rose bush. They can also reproduce sexually when their flowers are pollinated. What is the primary advantage of sexual reproduction in roses?
What is genetic variation

A genotype with two different alleles?
What is heterozygous?

How can an asexually reproducing organism get a mutation?

Some plants, like dandelions and maple trees, have lightweight seeds that are carried by the wind, while others, like berries, rely on animals to eat and spread their seeds.
Explain how these different seed dispersal methods increase the chances of successful reproduction.
Both methods help spread offspring to new locations where they can grow without competing with the parent plant. Wind dispersal allows wide spreading over large areas, while animal dispersal often places seeds in nutrient-rich soil (from animal waste), increasing the likelihood of germination and survival.
