Beaks Battle post discussion

Write down your result in Table 1

Draw a natural selection graph based on the result you obtained from the Beaks battle activity

From the activity, which beak is not fit to survive with the environment?

• Small beak

• Medium beak

• Large beak

• All beaks

Give your reason for the answer in question 2

Name the type of Natural Selection that can be relate with the results of the feeding abilities.

• Stabilising Selection

• Directional Selection

• Disruptive Selection

Describe the potential impact on the bird population due to environmental changes.

State any other example that experience the same type of natural selection

• Black peppered moth during the industrial revolution

• Hair of animals at different temperature

• Baby birth weight

• Body size of black bear

Answer explanation

The correct choice, hair of animals at different temperatures, is another example of natural selection where the hair of animals adapts to varying environmental conditions.

Disruptive selection is favour towards ________ phenotypes and act against the ______ phenotypes

During a research study on human birth weight, scientists found that the intermediate phenotypes are favored and act against both extreme phenotypes. What is this phenomenon known as?

• Stabilising selection

• Directional Selection

• Disruptive Selection

Answer explanation

Stabilising selection favors intermediate phenotypes and acts against extreme phenotypes, maintaining the status quo.

Which of the following examples does not demonstrate natural selection?

• Black peppered moth during the industrial revolution

• Hair of animals at different temperature

• Body size of black bear

Answer explanation

The body size of a black bear is not a result of natural selection but rather genetic variation or environmental factors, unlike the other examples which directly involve natural selection.
