BIOLOGY FINAL EXAM REVIEW WITH 100%
VERIFIED ANSWERS LATEST 2024-2025
1. Abiotic: non-living
2. Autotroph: an organism that makes its own food.
3. Asexual reproduction: a reproductive process that involves only one
parent and produces offspring that are identical to the parent
4. Biotic: living
5. Biosphere: consists of all life on earth and all parts of the earth in
which life exists, including land, water, and the atmosphere.
6. Cell specialization: cells throughout an organism can develop in
different ways to perform different tasks.
7. Cell differentation: process by which cells become different types of
cells
8. Carbon cycle: cyclic movement of carbon in different chemical forms
from the environment to organisms and then back to the environment.
9. Cell differentiation: the process by which a cell becomes specialized
for a specific structure or function
10. Chemical bond: the attractive force that holds atoms or ions together
where the energy in a compound is stored
11. Chromosome pair: identical copies of a single chromosome copy of
mom chromosome 1 next to mom chromosome 1
12. Consumer: an organism that obtains energy by feeding on other
organisms
13. Deletion: the loss of a part of dna from a chromosome
14. Detritivore: an organism (like the earthworm) that feeds on decaying
matter after it has been broken down by decomposers.
15. Dna: deoxyribonucleic acid; the genetic material that carries
information about an organism that is passed from parent to offspring
and is used by an individual as the recipe for making proteins
16. Dna sequence: the sequence, or order, in which the nitrogenous bases
adenine (a), cytosine (c), guanine (g), and thymine (t) are arranged in a
gene or a dna fragment, or in an organism's genome.
17. Double helix: two strands of nucleotides wound about each other;
structure of
Dna
1/6
, .
18. Ecosystem stability: the total number of species is fairly consistant
from year to year---the same species were present each year--- the
population size of each species was approximately the same from year
to year
19. Endangered species: a species whose numbers are so small that the
species is at risk of extinction
20. Exponential growth: growth pattern in which the individuals in a
population reproduce at a constant rate
21. Food web: a community of organisms where there are several
interrelated food chains
22. gene: sequence of dna that codes for a protein and thus
determines a trait
23. Genetic diversity: the amount of variation in the genetic
material within all members of a popualtion
24. Genetic variation: the variety of different types of genes in a species or
population.
25. Genotype: an organism's genetic makeup, or allele combinations
26. Greenhouse effect: natural situation in which heat is retained in earth's
atmosphere by carbon dioxide, methane, water vapor, and other gases
27. Heterozygous: having two different alleles for a trait
28. Heterotroph: an organism that cannot make its own food and thus eats
other organisms
29. Homeostasis: process by which organisms maintain a relatively stable
internal environment.
30. Insertion: a mutation involving the addition of one or more nucleotide
pairs to a gene.
31. Inversion: (genetics) a kind of mutation in which the order of the genes
in a section of a chromosome is reversed
32. Logistic growth: growth pattern in which a population's growth rate
slows or stops following a period of exponential growth
33. Messenger rna: type of rna that carries genetic information from dna in
the nucleus to direct protein synthesis in the cytoplasm; process of
making it is called transcription
34. Phenotype: physical characteristics of an organism
35. Polygenic trait: trait that is controlled by two or more gene
combinations
36. Point substitution: when one nucleotide is substituted for another
37. Product: element or compound produced by a chemical reaction
