Cheetahs have been very close to extinction due to over hunting. There is little genetic diversity left in their species. Which of the following is a result of the limited diversity in current cheetah population?
a) Current cheetah populations are more resistant to disease.
b) The survival rate of young cheetahs will increase.
c) Current cheetahs are less likely to adapt to environmental changes.
d)
Put the following steps explaining the process of evolution in the correct order. Number each step appropriately (e.g. label the first step 1).
a) 1 Mutations produce variation 2 Organisms with better variations survive. 3. It builds up in the population. 4. New species.
b) 1. New species 2. Organisms with better variations survive 3. It builds up in population 4 Mutations produce variations
c) 1. Mutations produce variation 2. It builds up in the population 3. Organisms with better variations survive 4. New species
d) 1. Mutations produce variation 2. New species 3. Organisms with better variations survive 4. It builds up in the population
Individuals within a population have slightly different traits, called variations. How do variations improve the likelihood that a population will survive?
a) Variation enables individuals to produce offspring that will survive into adulthood.
b) Variation enables the population to create new genes, which help individuals survive a significant change in their environmen
c) Variation provides the raw material upon which natural selection acts in a population.
d) Variation enables individuals who are very different from the rest of the population to reproduce more successfully.
