munaraku väljumine. erektsioon - peenise jäigastumine ejakulatsioon -seemnepurse kaksikud - ühemunaraku-sisse mitu spermatosoidi. erimunaraku-2 erinevat viljastatud munarakku. Viljastumine toimub munajuhas, kui seemnerakk tungib munarakku. Loode areneb emakas.Isast oleneb lapse sugu. Munarakul aint x kromosoonid. x+x=girl. x+y=poiss Korgaskeha sisse valguv veri -peenis jäigastub. Suguelundid- munandid(tootavad seemnerakke),eesnääre(toodab spermat),korgaskeha(jäigast.)

1) Behavior can be innate, because it is genetically based. Evolution may play a key role in behavior. 2) Animals may be studied as a means of understanding human behavior. 3) There are biological correlates of behavior. Cognitions, emotions and behaviors are products of the anatomy and physiology of our nervous and endocrine system. Explain how principles of the biological level of analysis may be demonstrated in research. 1) Correlational studies: Study by Buss, who hypothesized that across cultures, men will prefer to marry younger women because of greater reproductive capacity and women will place greater value on a potential mate's earning potential to provide survival advantages. This evolutionary hypothesis was tested in 37 cultures by sending out questione...
