What is half-life in the context of radioactive decay?

Back

Half-life is the length of time required for half of the radioactive atoms in a sample to decay.

Front

Why are rhinos with shorter horns increasing in number?

Back

Rhinos with short horns have a greater chance to reproduce due to the overhunting of the long-horned individuals.

Front

Back

The correct order is E, B, C, D, A.

Front

Why is DNA important?

Back

DNA serves as the blueprint for traits of all living things.

Front

What is genetic diversity?

Back

Genetic diversity refers to the variety of genes within a species, which is crucial for a population's adaptability and survival.

Front

How does natural selection work?

Back

Natural selection is the process where organisms better adapted to their environment tend to survive and produce more offspring.

Front

What is the role of mutations in evolution?

Back

Mutations are changes in DNA that can lead to new traits, contributing to genetic diversity and evolution.

Front

Define evolution.

Back

Evolution is the change in the heritable characteristics of biological populations over successive generations.

Front

What is the significance of fossils in understanding evolution?

Back

Fossils provide evidence of past life forms and show how species have changed over time.
