the cervix

What deposits semen within the female reprotuctive tract?

the penis

what does parturition mean?

giving brith

What are the two signs of heat?

1. swelling of the vagina
2. 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?

Explain the weatheing process of a rock .

1. water collects in rock cracks
2. freezes and expands; larger cracks
3. more water enters the crack
4. freeze cracks enlarge; breaking into smaller parts
5. cracks collect soil and seeds
6. a seed grows and roots break down the roots

What are the 4 functions of soil for plants?

1. Type of orginal or parent material
2. Climate temperature rainfall
3. Type of organisims living on land or not including plants
4. Topography steep or flat

Name the 10 uses for soil

1. road beds
2. concrete and asphalt
3. foundation for structures and bodies of water
4. crops
5. used in landfills
6. livestock
7. wildlife
8. praries
9. forests
10. 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.
