Population Growth
What type of population growth can be seen when a population has limited resources?
logistic (s-curve)
What type of cell lacks a nucleus and membrane-bound organelles?
prokaryote
This cell organelle is the physical site where proteins are assembled.
ribosomes
Reproduction can be divided into these two categories.
asexual and sexual
This term describes an allele that always expresses its phenotype, even if only one copy is present in the genotype.
dominant
What is the term for the maximum number of individuals of a species that an environment can support long-term?
carrying capacity
By what asexual process do bacteria typically reproduce and divide?
binary fission
Name the two steps of protein synthesis.
What type of cells go through mitosis?
body cells/somatic cells
In this inheritance pattern, a cross between a red flower and a white flower produces pink offspring, showing a "blending" of traits.
List 3 things that could be considered limiting factors
food, water, space, diseas, natural disaster
What is the primary circular structure that contains the genetic material in a bacteria cell?
plasmid
If a DNA template strand reads T-A-C, the resulting mRNA strand will have this sequence.
A-U-G
A mouse has 15 chromosomes in it's sperm cells. How many chromosomes would be in the liver cell of the mouse?
30
In this type of genetic family tree, a shaded-in circle represents a female who expresses the specific trait being studied.
pedigree
If a non-native predator is introduced to a North Carolina wetland and has no natural enemies, what type of growth is its population most likely to exhibit initially?
exponential
While many people think antibiotics cause mutations, this biological process is what actually occurs when an antibiotic kills off weak bacteria, leaving only the naturally resistant ones to reproduce and dominate the population.
natural selection (evolution)
This is the specific three-base sequence on an mRNA strand that codes for a single amino acid.
codon
During fertilization, two haploid gametes meet to form a...
zygote
This error occurs during Meiosis when homologous chromosomes fail to separate, leading to gametes with too many (trisomy) or too few chromosomes (monosomy).
non-disjunction
If an apex predator is removed from an ecosystem, resulting in an overpopulation of herbivores that then deplete the primary producers, what ecological phenomenon has occurred?
trophic cascade
Which specific part of the bacterial cell does the antibiotic target to cause the cell to burst?
cell wall
This type of mutation, which causes Sickle Cell Anemia, alters the shape of the entire hemoglobin molecule by changing just ONE nucleotide.
point mutation - substitution
During Prophase I of meiosis, this event occurs where homologous chromosomes exchange segments of DNA.
crossing over
To determine if a dominant-looking organism is homozygous (BB) or heterozygous (Bb), a breeder should cross it with an individual that has this specific genotype.
homozgous recessive (bb)
