Oviparity ex

All birds

Oviparity eggs fertilized ____ and _____ complete development

internally, depostited outside

Evolution amniotic egg let land animals to reproduce outside water

Oviparity

Ovovivipairty ex

Bony fish

Ovovivipairty fertilized _____ retain in _____ development

internally, mom

Viviparity ex

mammals

Viviprity devolp + nourishment

in mom + moms blood

Evolved only in mammals

Viviparity

4 seminal fuild

sperm, 3 glands (Seminal vesicles, Prostate gland, Bulbourerthal gland)

Seminal vesicles

fluid w/nutrients for sperm

Prostate gland

milkly alkiane fuild active sperm

bulbourethral gland

mucous w/lubricating effect

Proximate

What behavoir/mechanism

Hydrolgic cycle

water in ocean evaporates,wind distribute water (vapor), water condeneses in rain/fog/snow, organism emit moisture thru respiration/perspiration, mosisture reneters atmosphere, back in ocean

3 types of feriltization

ovipaorty,oviviparity,vivparity

Menstrual cycle 1-5 day

low horomes, endometrium disinterges, menstruation

Menstrual cycle 6-13

increase estrogen, endomertium thickens

14-28

Ovulation

15-28

increase progestrone, endomertium doubles thickness, utering glanda prep for embryo,low hormones, repeat

Nitrogen cycle

Plants get nitrogen from nitrogen-fixing bacteria in roots, bacteria combons w/H + N2, make NH3 and NH4+,baeria combo w/NH3 w/O, form NO2-,baceria NO2- to NO3-, plants aborb, turn to amion acids, protein

Realized niche + fox

species adpat physical tolracte + limit resources

Fundmental niche + bird
