What are the cellular activities necessary for life?
incorrect
16.
Describe diffusion in cells?
incorrect
17.
What repackages proteins into forms the cells can use, expel, or keep stored?
incorrect
18.
Which variable is set by the experimenter, and influences the results of the experiment?
incorrect
19.
What is the impact of temperature and pH on cell function?
incorrect
20.
What is a protein that interferes with the replication of viruses?
A.
Interferon
B.
Modern health practices emphasize sanitation, the safe handling of food and water, aseptic techniques to keep germs out of the body, and the development of vaccinations and other chemicals and processes to destroy microorganisms
C.
Independent Variable
D.
mRNA
E.
Contains DNA and is the site where RNA is made?
F.
Schwann
G.
The double helix model explained how heredity information is transmitted and provided the basis for an explosion of scientific research in molecular genetics
H.
Hydrolysis
I.
Hypothesis
J.
Basic
K.
Acidic
L.
Golgi bodies
M.
Diffusion occurs in cells when substances (oxygen, carbon dioxide, salts, sugars, amino acids) that are dissolved in water move from an area of higher concentration to an area of lower concentration.
N.
Chemical reactions that facilitate acquiring energy, reproduction, and adaptation/maintaining homeostasis.
O.
Field study
P.
Chromatography
Q.
Rosalind Franklin
R.
Because every cell has a particular pH at which it functions best
S.
Contains the digestive enzyme.
T.
Most cells function best within a narrow range of temperature and pH. At very low temperatures, reaction rates are too slow. High temperatures or extremes of pH can irreversibly change the structure of proteins and alter their function.
