What deposits semen within the female reprotuctive tract?
the penis
what does parturition mean?
giving brith
What are the two signs of heat?
swelling of the vagina
Vaginal discharge
What hormone causes an animal to come into heat?
estrogen
What is the external (outside) portion of the female reproductive tract?
the vulva
What are the female reproductive parts?
vulva, vagina, urethra, cervix, uterus, infindibullum, ovary
What are the FUNCTIONS of the female reproductive parts?
to produce eggs, maintain pregnancy hormones, secret hormones, create eggs from sperm, hold the ovary, allow urination etc.
Cervix
the lower part of the uterus that connects to the vagina.
Ovary
the female reproductive organ that produces eggs.
Uterus
the organ where the fertilized egg implants and develops into a fetus.
Estrus
the period of sexual receptivity in female animals.
Fallopian tube
the tube that connects the ovary to the uterus and where fertilization occurs.
Define soil
the layer of natural materials on the earths surface containing organic and non organic materials capable of growing and supporting plant life.
What are the 3 major horizons?
surface of the horizon, subsoil, substratum
what are the five items included in soil?
living organisims, mineral matter, air, water, decaying organic material.
What is the purpose of living organisms in soil?
to break down organic matter and convert nutrients init forms that plants can use
how much volume does air make in soil?
1/2 soil mixture on volume basis
Explain the weatheing process of a rock .
water collects in rock cracks
freezes and expands; larger cracks
more water enters the crack
freeze cracks enlarge; breaking into smaller parts
cracks collect soil and seeds
a seed grows and roots break down the roots
What are the 4 functions of soil for plants?
Type of orginal or parent material
Climate temperature rainfall
Type of organisims living on land or not including plants
Topography steep or flat
length of time that parent material has been weatherd
Name the 10 uses for soil
road beds
concrete and asphalt
foundation for structures and bodies of water
crops
used in landfills
livestock
wildlife
praries
forests
filter systems for hydrolic cycles
Explain the relationshoip between particle size and permiability
The smaller particles are are not able to pass through because of the amount of space. Which delays the time water will take to pass through.
what are the four stomach compartments?
rumen - food gets regurgitated and into cud
omasum - many piles stomach absorbs water and other substances
abomasum - breaks down proteins
reticulum - metal accumulates. smallest stomach compartment
Explain the relationship between particle size and porosity
the relationship is both ending in being able to allow water to pass through and to absorb the water and the bigger or smaller the particles are will determine how long it will take the water.
