CNIH Entrance Exam Study Questions
with 100% Correct Answers | Expert
Graded A+
1. cell membrane - ANSWER controls what goes in and out of the cell, filled
with proteins and enzymes
2. Endoplasmic Reticulum - ANSWER Transports proteins and materials
throughout the cell
3. Atoms - ANSWER Smallest whole unit of matter. Protons and neutrons
located in nucleus, electrons located in energy shells
4. Cell membrane - ANSWER Filled with proteins and enzymes- controls
what comes in and out of the cell.
5. Endoplasmic Reticulum - ANSWER System of tubes made from
membranes- transports proteins and other material throughout the cell
6. Ribosome - ANSWER Very small structures made of DNA and protein-
found in ER
7. Golgi body - ANSWER Membrane tubes in a bundle with buds of
membrane coming off- sorts, packages and ships proteins.
8. Mitochondria - ANSWER Powerhouse of the cell. Produces energy from
food. Performs cellular respiration.
,9. Nuclear membrane - ANSWER Allows genetic code to communicate with
ribosomes. Controls what comes in and out of the cell.
10.Nucleus - ANSWER Control center of cell, has a membrane which holds
and protects chromatin.
11.Nucleolus - ANSWER Circular structure inside nucleus- makes ribosomes
12.Chromatin - ANSWER DNA bundled in nucleus with proteins- code for
proteins (genetic code)- chromosomes allow for DNA to be packaged.
13.Centriole - ANSWER 2 perpendicular bundles of tubes- involved in cell
division (In animals ONLY)
14.Chloroplast - ANSWER Oval-shaped organelle filled with stacks of protein-
main site of photosynthesis (In plants ONLY)
15.Cell wall - ANSWER Outer coverings of cell- maintains structure (In plants
ONLY)
16.Cell Cycle - ANSWER Entire period of cells life (Interphase, G1, G2,
Mitosis)
17.Independent variable - ANSWER Variable that is manipulated- should only
be one
, 18.Dependent variable - ANSWER Measure variable- responds to changes in
independent variable
19.Biological diversity - ANSWER Number and variety of species and
ecosystems on earth (Species, Structural, Genetic)
20.Biodiversity importance - ANSWER More biodiversity= more resistant to
change
More feeding relationships- ensure food supply
Nutrient cycling
21.Biodiversity threats - ANSWER Habitat loss
Climate change
Over-exploitation
22.Taxonomy - ANSWER The science of classifying all organisms (living and
fossil)
23.Dichotomos key - ANSWER Sort organisms into smaller and smaller
groups based on characteristics
24.Carl Linnaeus - ANSWER The father of taxonomy who classified
organisms based on similarities
25.Binomial Nomenclature - ANSWER Formal system of naming species
where each species is assigned a genus name
26.Genus - ANSWER Group of species that share similar characteristics
