Final Study Day Flashcards
is ringworm difficult to treat?
no
are dominant or recessive alleles more likely to be passed to offspring?
recessive alleles
what is the leading cause of death in dogs in the US
cancer
how does the rabies virus replicate?
it enters through the muscle tissue and replicates in the nervous tissue
how does a mother dog’s need for food change throughout the pregnancy?
need for food increases throughout pregnancy, is highest during lactation, and decreases after lactation
what is the function of the pancreas?
produce digestive enzymes
advantage to inbreeding
increased predictability and homozygosity of traits
disadvantage to inbreeding
increased deleterious (harmful) recessive traits
fomite
non animal object that spreads disease
2 organs that use microorganisms to digest fibers
cecum and rumen
why is protein not a good energy source
excess nitrogen hard on kidneys
gall bladder function
bile production to break down fats
6 infectious diseases
bacteria
viruses
protozoa
fungi
parasites
prions
characteristics of amphibians
skin without scales
heterothermic
three chambered heart
fresh water and terrestrial
characteristics of reptiles
don’t go through metamorphosis
heterothermic
almost all have three-chambered heart
body covered with scales
air-breathing
terrestrial (secondarily aquatic)
6 non infectious diseases
nutritional deficiencies or excesses
metabolic disorders
inherited disorders
maladaptation
cancers
proestrus
FSH levels increase
follicles stimulated, start producing estrogen
estrus/heat
only time male and female will mate
high levels of FSH, estrogen
low levels of progesterone
LH surge
metestrus
ovulation, follicle opens and releases ovum
diestrus
period before next proestrus
corpus luteum forms in ruptured follicle, secretes progesterone
if no pregnancy, prostaglandin causes CL regression
estrogen
produced by cells in follicle
necessary for development of secondary sex characteristics in female
stimulates estrus
