A balanced polymorphism (maintenance of multiple genotypes) exists through disruptive selection in seedcracker finches from Came

roon in which small- and large-billed birds specialize in cracking soft and hard seeds, respectively. If long-term climatic change resulted in all seeds becoming hard, which type of selection would then begin to operate on bill size in the finch population?
A. directional selection
B. disruptive selection would continue to operate
C. stablilizing selection
D. no selection will operate on bill size following the climate change

Answer:

The correct answer is option A. "directional selection".

Explanation:

Directional selection is a type of natural selection at which traits with extreme characteristics are selected over traits with medium characteristics. In this case,  a long-term climatic change resulted in all seeds that are the fountain of food for finch becoming hard. This will result in a directional selection on bill size in the finch population, where large-billed birds will be selected over small and medium-billed birds.

A GeoChart is a tool used to visualize data on a map. The size of the circular
7nadin3 [17]

Explanation:

We know that the larger the circle, the more large the diameter of the circle the more the quantity being studied.

We can clearly see that the South eastern coast of Australia has more number of people diagnosed with cancer.

The South western and the Northern part also records a sizable amount of skin cancer cases.

  • In the middle part of the map where the circles are small, the number of people diagnosed  with cancer is very low
  • Other areas without the circle did not record any case of skin cancer.

Which of the following correctly compares Ornithischian and Saurischian dinosaurs?
kumpel [21]

Answer:

The option c is partly correct.

Explanation:

None of the statements is completely accurate because:

a. Saurischian dinosaurs include theropod and sauropod dinosaurs, and their common ancestors. Ornithischians comprise neornithischians (ornithopods and ceratopsians), thyreophorans (ankylosaurs and stegosaurs) and heterdontosaurids.

b. Capability to fly has only been documented in fossils belonging to Saurischia (where the birds are also classified in). Feathers, on the other hand, do appear in the two clades. Feathers, however, are not a trait exclusively associated to flight.

c. This is a correct comparison between ornithischians and saurischians in the sense that the attributes do belong to these clades, but when comparing animals there most be a comparison that reflects a pattern. Ornithischians have leaf shaped teeth suited to eat plant material, whereas saurischians have teeth for a carnivore and herbivore diet.

d. Sauropods are saurischians and they evolved herbivory from a meat-eater ancestor.

Kruka [31]

Answer:

The law of segregation is the Mendel’s laws or principles explain that traits are passed from parents to offspring individually instead of as pairs, groups or sets.This is a law or principle which states that during the formation of gametes, two copies of each heredity factors separate out so that the new offspring can get one factor of both the parents. This law was the first law in this direction.
