9TH GRADE BIOLOGY FINAL EXAM
QUESTIONS AND ANSWERS RATED A+
He though evolution was a fast process, and he thought through use and disuse of
organs, traits can be acquired and lost. Those new traits would then be passed to
offspring - ANSWER-Who was Lamark
He came up with the theory of evolution through studying fossils, finches and
turtles on the galapagos islands. - ANSWER-Who was Darwin
They figured out that the earth was millions of years old and that the geological
processes that changed/formed the earth in the past still occur now - ANSWER-Who
were lyell and hutton
When earth provides the genetic variation and nature breeds the animals with good
traits leading to evolution - ANSWER-What is natural selection
When earth provides the genetic variation and humans breed the traits they find
useful for survival - ANSWER-What is artificial selection
they did an experiment using lightening and compounds of the earth to make
amino acids which are an important component in life, to show that life could have
started from organic compounds - ANSWER-Who were urey and miller?
Point mutations are when one of the bases switches so it's not paired with the
correct base pair - ANSWER-Point mutations
When the mRNA reads the the bases, there is a problem and there is a shift that
skips over a sequence, or the nucleotide sequence is inserted or deleted - ANSWER-
Frame shift mutations
when there are too many or not enough chromosomes leading to diseases such as
down syndrome (caused by nondisjunction) - ANSWER-What are chromosomal
mutations
A double helix connected by base pairs - ANSWER-What is the structure of DNA
the old strands split and there is one old one and one new one in each DNA -
ANSWER-what is made from DNA replication
The nucleus - ANSWER-Where does transcription occur
