Question 8

In a remote island ecosystem, a population of a particular bird species exhibits varying beak sizes. A sudden and prolonged drought drastically reduces the availability of small, soft seeds, leaving primarily large, hard seeds as the food source. Over several generations, the average beak size of the bird population is observed to significantly increase. Which of the following evolutionary mechanisms best explains this change in the bird population?

Accepted Answer

C. Natural selection — This scenario describes natural selection. The drought acts as a selective pressure, favoring birds with larger beaks that are better adapted to crack the available large, hard seeds. These birds are more likely to survive, reproduce, and pass on their genes, leading to an increase in the average beak size over generations. Genetic drift involves random changes in allele frequencies, gene flow is the movement of alleles between populations, and mutation introduces new alleles, but none of these mechanisms primarily explain the directed change in response to an environmental pressure as effecti

Answer

A. Genetic drift

Answer

B. Gene flow

Question 10

An unknown element 'Z' is found to have its last electron entering a p-orbital, and it readily forms an anion with a -1 charge. Based on this information, which of the following statements is most likely true about element 'Z'?

Accepted Answer

C. It is a halogen, typically found in Group 17 of the periodic table. — An element with its last electron entering a p-orbital belongs to the p-block. Forming an anion with a -1 charge signifies that the element needs one electron to achieve a stable octet configuration. This characteristic property belongs to Group 17 elements, also known as halogens. Noble gases are chemically inert and do not readily form ions, s-block elements typically form cations, and d-block elements (transition metals) usually form cations with variable valencies.

Answer

A. It belongs to the s-block and is a highly reactive metal.

Answer

B. It is a noble gas, characterized by its chemical inertness.

Answer

D. It belongs to the d-block and exhibits variable valency.
