Question

what is the best definition of a population?
a group of individuals of two different species that interact with each other
a group of interbreeding individuals from different geographical regions
a group of potentially interbreeding individuals of the same species regardless of where they live
a collection of different species living in the same area at the same time
a group of interbreeding individuals of the same species in a given area
question 11 (2.5 points)
which group represents the oldest living plant lineage?
hornworts
liverworts

Explanation:

A population is defined as a group of interbreeding individuals of the same species in a given area. This is a fundamental concept in biology. The other options are incorrect because:

• A group of individuals of two different species is a community (not a population).
• Interbreeding individuals from different geographical regions (if they are not in the same area) do not form a population.
• "Potentially interbreeding regardless of where they live" is too broad; a population is in a specific area.
• A collection of different species is a community.

For the second question, liverworts are considered one of the oldest living plant lineages.

Answer:

For the first question: a group of interbreeding individuals of the same species in a given area.
For the second question: liverworts.
