Q180

Which concept did Darwin describe as “descent with modification”?

  • A) Branching inheritance
  • B) Evolutionary changes over generations
  • C) Sudden creation
  • D) Natural selection
AI Explanation
Darwin used the phrase “descent with modification” to describe how species change over generations while inheriting traits from common ancestors. It is a fundamental concept of evolutionary theory.

Q181

What type of evidence is provided by molecular homologies?

  • A) Molecular and biochemical
  • B) Environmental
  • C) Anatomical
  • D) Geological
AI Explanation
Molecular homologies compare DNA, RNA, and protein sequences among organisms. Similarities in these molecules provide evidence of common ancestry and evolutionary relationships.

Q182

What happens during gene duplication that can lead to new gene functions?

  • A) Genes are lost
  • B) Genes are copied and may take on new roles
  • C) Genes stop working
  • D) Genes mutate immediately
AI Explanation
Gene duplication creates extra copies of genes, allowing one copy to maintain the original function while another can accumulate changes. These changes may result in new gene functions over time.

Q183

How old is the Earth estimated to be?

  • A) 6 billion years
  • B) 2.5 billion years
  • C) 4.5 billion years
  • D) 12 billion years
AI Explanation
Scientific evidence indicates that Earth formed approximately 4.5 billion years ago. This estimate is based on radiometric dating of rocks and meteorites.

Q184

Why was there little or no oxygen in the early Earth's atmosphere?

  • A) Oxygen was locked in rocks
  • B) Because volcanoes consumed oxygen
  • C) Because of strong magnetic fields
  • D) There were no oxygen-producing organisms
AI Explanation
Early Earth's atmosphere lacked significant oxygen because organisms capable of oxygen production, such as cyanobacteria, had not yet evolved. Oxygen levels increased later through photosynthetic activity.

Q185

What do analogous structures have in common?

  • A) Similar function, different evolutionary origin
  • B) Identical DNA sequences
  • C) Similar origin and structure
  • D) Different function and origin
AI Explanation
Analogous structures perform similar functions but evolved independently from different ancestral structures. They are examples of convergent evolution rather than common ancestry.

Q186

What is microevolution primarily caused by?

  • A) Artificial selection
  • B) Natural disasters
  • C) Mutation in unrelated species
  • D) Changes in allele frequencies due to natural selection
AI Explanation
Microevolution refers to small-scale genetic changes within a population, mainly involving shifts in allele frequencies. Natural selection is one of the major mechanisms driving these changes.
BT201 Final Term AI Solved
Q187

What is the role of the Hardy-Weinberg principle in genetics?

  • A) Counts total alleles
  • B) Acts as a baseline to compare evolving populations
  • C) Identifies dominant genes
  • D) Measures mutation rates
AI Explanation
The Hardy-Weinberg principle describes genetic equilibrium conditions where allele frequencies remain constant. It provides a reference point for identifying whether evolutionary forces are affecting a population.
BT201 Final Term AI Solved
Q188

What does the fossil record help scientists determine?

  • A) Formation of crystals
  • B) Future evolution of humans
  • C) History of life and extinct organisms
  • D) How fossils look under a microscope
AI Explanation
The fossil record provides evidence about past organisms, their evolution, and extinction events. It helps scientists reconstruct the history of life on Earth.

Q189

What is the primary habitat of the spiny anteater?

  • A) Asia
  • B) Australia
  • C) South America
  • D) North America
AI Explanation
The spiny anteater, also known as the echidna, is native to Australia and nearby regions. It is a unique egg-laying mammal belonging to the monotreme group.

Q194

Which scenario is most likely to lead to speciation over time?

  • A) Introduction of dominant alleles to a large population
  • B) Migration of a few individuals followed by inbreeding
  • C) Mutation of recessive alleles
  • D) A stable population with high diversity

Q195

Fixation in terms of genetic drift means:

  • A) Mutation of all alleles
  • B) Inheritance of two alleles
  • C) An allele becomes the only one present at a locus
  • D) Dominance of all genotypes
AI Explanation
In genetic drift, fixation occurs when random changes in allele frequencies result in one allele becoming the only allele remaining at a particular genetic locus. The fixed allele is then present in all individuals of the population.

Q196

What are the two main effects associated with genetic drift?

  • A) Mutation and Selection
  • B) Founder effect and bottleneck effect
  • C) Natural selection and adaptation
  • D) Speciation and mutation
AI Explanation
The founder effect and bottleneck effect are the two major consequences of genetic drift. Both involve random changes in allele frequencies, especially in small populations.

Q197

What is the main element used in radiometric dating besides carbon?

  • A) Nitrogen
  • B) Potassium
  • C) Oxygen
  • D) Sulphur
AI Explanation
Radiometric dating uses the decay of radioactive isotopes such as potassium-40 to estimate the age of rocks and geological events. Carbon dating is another method mainly used for more recent organic remains.
BT201 Final Term AI Solved
Q198

What does the Hardy-Weinberg theorem primarily state?

  • A) Dominant alleles increase over time
  • B) Mutations are random events
  • C) Genotype changes occur in every generation
  • D) Allele frequencies remain constant across generations in the absence of evolutionary forces
AI Explanation
The Hardy-Weinberg theorem states that a population's allele and genotype frequencies remain unchanged when no evolutionary mechanisms are acting. It serves as a model for detecting evolutionary change.
BT201 Final Term AI Solved
Q199

Natural selection is limited because it acts on:

  • A) Phenotypes of individuals
  • B) Codominant alleles
  • C) DNA sequences directly
  • D) Environment only
AI Explanation
Natural selection acts on observable traits, or phenotypes, rather than directly on DNA sequences. Individuals with advantageous phenotypes tend to leave more offspring, affecting allele frequencies over time.
