asexual reproduction - ANSWER ✅all of the genes in a cell are passed to its
daughter cells. Resulting cells are clones, identical copies of the parent cell
sexual reproduction - ANSWER ✅genes of two parents are combined resulting in
genetic variability
Gamets - ANSWER ✅reproductive cells, sperm cells and egg cells
Meiosis 1 - ANSWER ✅(reduction division) during this stage the number of
chromosomes in the parent cell are divided in half because of homologous
chromosomes are separated.
Meiosis 11 - ANSWER ✅sister chromatids separate
gene - ANSWER ✅is a region of a chromosome that has a specific function
phenotype - ANSWER ✅An organism's or visible traits.
genotype - ANSWER ✅genetic makeup of an organism
Homozygous - ANSWER ✅cells that have the same allele
heterozygous - ANSWER ✅cells that have different alleles
, Punnettt square - ANSWER ✅A chart that shows all the possible combinations of
alleles that can result from a genetic cross
Law of Segregation - ANSWER ✅Mendel's law that states that the pairs of
homologous chromosomes separate in meiosis so that only one chromosome from
each pair is present in each gamete
Dominant - ANSWER ✅Describes a trait that covers over, or dominates, another
form of that trait.
recessive - ANSWER ✅trait of an organism that can be masked by the dominant
form of a trait
monohybrid cross - ANSWER ✅A cross between individuals that involves one
pair of contrasting traits
dihybrid cross - ANSWER ✅a cross between two individuals. both f who are
heterozygous for two traits
law of independent assortment - ANSWER ✅Mendel's second law, stating that
allele pairs separate from one another during gamete formation
deoxyribonucleic acid (DNA) - ANSWER ✅houses the genetic material for all
living organisms
ribonucleic acid (RNA) - ANSWER ✅mRNA, is a copy of DNA to be used as a
template to make protein
DNA replication - ANSWER ✅the process of making a copy of DNA
Biology - ANSWER ✅the scientific study of life
Biologists - ANSWER ✅study how humans and other living organisms interact
with their environment.
Biology - ANSWER ✅is the scientific study of life and is the branch of science
that studies living organisms and the way organisms interact with their
environments.
, To be considered alive, something must be made up of 5 distinct qualities: -
ANSWER ✅-Be made of materials organized in a hierarchical pattern.
-Use energy and raw materials to survive.
-Sense and respond to changing environments and maintain internal stability, or
homeostasis.
-Grow, develop, and reproduce.
-Be part of a population that evolves.
cell - ANSWER ✅smallest living organism that shows all 5 characteristics of life
Matter - ANSWER ✅any substance that has mass and takes up space.
All matter can be classified in one of two categories: - ANSWER ✅biotic (living
or having lived) or abiotic (nonliving and never having been alive).
biotic - ANSWER ✅living or having lived
abiotic - ANSWER ✅nonliving and never having been alive
Atom - ANSWER ✅basic unit of matter
molecule - ANSWER ✅a chemical structure consisting of at least two atoms held
together by a chemical bond
Macromolecules - ANSWER ✅biologically important molecules that are
technically polymers
When macromolecules are used as building blocks to form a membrane-bound
sphere - ANSWER ✅you have a cell
two main types of cells - ANSWER ✅prokaryotes and eukaryotes
prokaryotes - ANSWER ✅small and simple; they do not have any clearly defined
compartments inside of them
eukaryotes - ANSWER ✅include membrane-bound organelles
, organelles - ANSWER ✅compartments inside the cell that contain specific groups
of macromolecules and carry out specific cellular functions
microorganisms - ANSWER ✅Single-celled life forms
Tissues - ANSWER ✅formed when similar cells work together to fulfill the same
detailed function
Organs - ANSWER ✅collections of tissues that work together to carry out a
common general function
organ system - ANSWER ✅a higher level of organization that consists of
functionally related organs
Organisms - ANSWER ✅individual living entities that survive and reproduce as a
unit
population - ANSWER ✅consists of all the individuals of a species living within
a specific area
populations can interact with each other in positive and negative ways, and
together they form a - ANSWER ✅community
ecosystem - ANSWER ✅consists of all the living things in a particular area
together with the abiotic, or nonliving, parts of that environment
biosphere - ANSWER ✅the collection of all ecosystems on Earth
emergent properties - ANSWER ✅characteristics of a system that do not appear
in any one of its component parts alone, but that appear when all parts are
combined.
Biome - ANSWER ✅Areas of the earth with similar characteristics of living and
nonliving things
What is the first level of organization that is alive? - ANSWER ✅The cell
