Evolution

Check the answers for the topic “Evolution” below:

Grade – 5 to12 Answers

Q. What is the theory of evolution?
Ans: a theory that explains how species change over time

Q. Does the Theory of Evolution explain how life first began?
Ans: No

Q. In science, what is a theory?
Ans: An explanation with massive amounts of evidence and facts to back it up.

Q. In selective breeding…
Ans: artificial selection of traits get passed on to many future generations, through the years

Q. Mutations are…
Ans: a genetic variation in a DNA sequence

Q. Is evolution an “accident?”

– can take millions of years
– is driven by natural selection
– can be difficult to understand because it takes a long time and many generations to see changes

Q. Why will there be more darker frogs over time?
Ans: There will be more darker frogs because they are not being eaten as much as the lighter frogs so more survive and pass on their genes (darker color) to their offspring.

Ans: Recessive (little g) alleles

Q. Mutations and variations are…
Ans: random

Q. Variations can be
Ans: positive, negative or neutral

Q. Natural selection __
Ans: selects those mutations that give an organism an advantage for survival
results in adaptations

Q. Bacteria are all the same and do not have variations within the species.
Ans: False

Q. Which type of bacteria have the greatest fittness?
Ans: Bacteria that become antibiotic resistant and are able to reproduce

Q. What makes bacteria dangerous when they undergo NATURAL SELECTION?
Ans: They can resist antibiotics and copy their genes to other bacteria to make people very sick

Q. What is a possible explanation for why an antibiotic would no longer work for someone?
Ans: The bacteria that survive pass on their resistance to their offspring so that over time all of the bacteria are resistant.
