Answers

1
Which statement best describes the relationship that exists among proteins, DNA and cells?
proteins combine to produce cells, which produce DNA
DNA is made of proteins, which tell a cell how to function
Cells contain DNA, which controls the production of proteins
proteins are made of DNA, which determines the cell produced
2
What will most likely happen if the human population continues to grow at current rates?
Fewer natural resources available for future generations
there will be a decrease in water pollution
there will be an increase in strong hurricanes
there will be an increase in nitrogen in the atmosphere
3
Which technique would most likely be used by forensic scientists?
gene cloning
karyotyping
DNA fingerprinting
gene therapy
4
Two kinds of birds live in the same area and eat the same food. What is there relationship?
predator-prey
competition
mutualism
parasitism
5
During exercise, temp increases. The body sweats to reduce temperature. Which is demonstrated?
homeostasis
synthesis
metabolism
excretion
6
Which is one reason scientists produce transgenic organisms?
to control microorganisms in the soil
to create new species of organisms
to treat certain types of diseases
to prevent habitats from being destroyed
7
What is the difference between the full classification of organisms and their scientific names?
classification and sci names differ in different countries
sci names include single nomen, full class has various nomen
sci names include order and family; full class is species
full class will include more categories than sci names
8
A strand of DNA has these bases: AGC CAT GTA TAC What is the complementary DNA strand?
TCG GTA CAT ATG
ACG GAT CTA TAG
UCG CUA CAU AUG
TGC CTA GAT ATC
9
Which process produces the most variation within a species?
sexual reproduction
asexual reproduction
cloning
mitosis
10
Before mitosis, which happens before the nucleus starts dividing?
homologous chromosomes cross over
The cytoplasm separates
The sister chromatids separate
The DNA replicates
11
A sea turtle washes up on a beach. Why should it be reported immediately to local authorities?
Can be useful to tourists who want to keep them as pets
Can be useful to protect sea turtles from predators
Could be useful to biologists trying to protect them
Can be useful to local fishermen who catch fish turtles eat
12
What are the subunits of DNA and their function?
monosaccharides that provide quick energy for the cell
proteins that are building blocks for organisms
nucleotides
lipids that store energy and provide insulation
13
How does the amount of energy from fermentation compare with that of aerobic respiration?
aerobic results in less energy
aerobic results in more energy
each results in equal energy
each results in variable amounts of energy
14
What is the effect of natural selection through the use of pesticides on insect populations?
pesticides alter natural selection by causing DNA to mutate
altered because the insects and predators are killed
rate decreased because pesticides kill only young insects
increased; pesticides do not kill those naturally resistent
15
What process explains how nerve cells and muscle cells develop from the same fertilized egg?
natural selection
differentiation
genetic engineering
selective breeding
16
What type of organic molecules are enzymes?
proteins
nucleic acids
carbohydrates
lipids
17
What is the function of autotrophs in the carbon cycle?
to use oxygen to produce glucose
to use carbon dioxide to produce glucose
to take in excess water
to feed on herbivores
18
Why is meiosis important for sexual reproduction?
allows zygote formed to have triple the chromosome number
allows the zygote to have half the original chromsomes
allows gamete to have twice the number of chromosomes
it allows gametes to have half the number of chromosomes
19
What will most likely be the result if all of the mitochondria are removed from a plant cell?
it will be unable to carry out respiration
it will break down the ribosomes in the cell
it will be unable to photosyntesize
it will lose water through osmosis
