4
The bond between two amino acids is called
a peptide bond
an ionic bond
a hydrogen bond
a carboxyl bond
5
Which of the following is an example of a genetically engineered organism
A new plant variety created by cross-pollination
A plant that naturally possesses medicinal properties
Seedless fruits made from grafting of one plant onto another
Plant received external DNA to produce natural insecticides
6
Which of the following best describes the process of the cell cycle
The interphase is the shortest phase in the cell cycle
Chromosomes are made up of coiled DNA
During the interphase, chromosomes are duplicated
Meiosis creates four new daughter cells
7
Based on the graph, which of the following can be said about enzymes
enzymes break down proteins
enzymes only work after a period of time goes by
enzymes need high temperatures to work
enzymes increase the rate of digestion
8
To determine paternity or criminals at a crime scene of investigation, which technique is used
recombinant DNA
invitro fertilization
stem cell therapy
DNA electrophoresis
9
How does using killed or weakened bacteria in an immunization help the body prevent infections
bacteria-fighting viruses are activated
antibodies are formed that fight those types of bacteria
bacterial reproductive cycles are disrupted
the body develops a fever that kills beneficial bacteria
10
Which is the best explanation for why the chromosome number is an even number in organisms
diploid chromosomes # is even so new cells gets same number
diploid chromosome # represents pairs, one from each parent
its only a coincidence, some organisms have odd numbers
chromosomes double every time cell divides so number is even

replace the beaker with a larger container
move the light source closer to the beaker
reduce the amount of water
use fewer plants
15
Which of the following is not part of the current modern cell theory
all living things have DNA
all living things come from other living cells
all cells including bacteria and viruses can reproduce
cells are the basic unit of all life
