Parasitology Exam 2 and answers
Transmission✔✔Fundamental, mode depends on parasite
-Fecal/oral
-Trophic (consumption)
-Direct Penetration
-Vector Transmission
-Sexual
-Vertical
Broadcast Reproduction✔✔A reproductive strategy in which reproductive propagules
are released into the environment to be dispersed by water or wind. Many eggs are
released.
Complex migration✔✔ascaris suum- migrate also through respiratory system.
Maintaining Position✔✔Used to cope with movement
-Adhesive discs
-Hooks
-Sinusoidal motion
-Acetabula
-Membrane proteins
-Morphology (claws)
Monoecious (hermaphroditic)✔✔male and female reproductive systems in one
animal
dioecious✔✔Having male and female reproductive organs in separate plants or
animals. Need a mate to reproduce
allele effect✔✔individuals in a population may have a hard time surviving or
reproducing if population size is too small. individual fitness decreases as population
density decreases
Phenology✔✔the study of cyclic and seasonal natural phenomena, especially in
relation to climate and plant and animal life.
Epigenetics✔✔the study of environmental influences on gene expression that occur
without a DNA change. Methylation is most common
restriction modification system✔✔A system used by bacteria to cleave exogenous
DNA at specific sites using a restriction endonuclease, and protect the sites on its
own DNA by methylation.
Phage Counter strategies✔✔Evolution with unusual nucleotides, cloaking, and
hijacking to avoid the immune system of the host.
CRISPR✔✔Clustered Regularly Interspaced Short Palindromic Repeats
