16 Questions
Why do organisms reproduce, based on the passage?
To create more individuals of the same species
How is the process of reproduction different from essential life processes like nutrition and respiration?
Reproduction is not necessary for individual organism's survival
How do we usually determine if two different individual organisms belong to the same species?
By their similar body designs
What brings organisms to our notice, according to the passage?
The large numbers of organisms belonging to a single species
Based on the passage, why is it important for an individual organism to reproduce?
To create new individuals of the same species
Why do reproducing organisms create new individuals that look very much like themselves, according to the passage?
To ensure the continuity of the species
What is the basic event in reproduction as mentioned in the passage?
Making copies of DNA
Why is simply pushing one copy of DNA out of the cell not feasible during reproduction?
The DNA copy would lack organized cellular structure
What is the basis for evolution according to the passage?
Variation in DNA copies during reproduction
What is the importance of consistency in DNA copying during reproduction?
It ensures survival in changing niches
Which cellular component contains the information for inheritance of features from parents to next generation?
Nucleus
What happens when information in DNA is changed?
Different proteins are made leading to altered body designs
Why is it expected that the process of copying DNA will have some variations each time?
Due to the unreliability of bio-chemical reactions
What will happen if the new DNA copy cannot work with the cellular apparatus it inherits?
The original cell will perish
Why are surviving cells similar but subtly different from each other according to the passage?
As a result of variations in the DNA copies generated during reproduction
What is the role of populations of organisms in an ecosystem according to the passage?
To fill well-defined places, or niches, and use their ability to reproduce
