Lorico [155]

Explanation:

1. У умных птиц у них только очень хорошо развит мозжечок.

U umnykh ptits u nikh tol'ko ochen' khorosho razvit mozzhechok.

2.  Это не правда; В случае самок птиц у нее один яичник, у них единственный - левый (правый атрофируется во время развития вместе с соответствующим яйцеводом), чьи соответствующие протоки открываются в клоаку или в половые отверстия.

V sluchaye samok ptits u neye odin yaichnik, u nikh yedinstvennyy - levyy (pravyy atrofiruyetsya vo vremya razvitiya vmeste s sootvetstvuyushchim yaytsevodom), ch'i sootvetstvuyushchiye protoki otkryvayutsya v kloaku ili v polovyye otverstiya.

3.Так и есть; зародышевый диск медленно растет на поверхности желтка с образованием бластодермы. Часть бластодермы, которая образует органы, является лишь частью бластодиска: zona pellucida; таким образом, инвагинация сводится к этой области в центральной первичной депрессии.

Tak i yest'; zarodyshevyy disk medlenno rastet na poverkhnosti zheltka s obrazovaniyem blastodermy. Chast' blastodermy, kotoraya obrazuyet organy, yavlyayetsya lish' chast'yu blastodiska: zona pellucida; takim obrazom, invaginatsiya svoditsya k etoy oblasti v tsentral'noy pervichnoy depressii.

4. Большинство видов гнездятся на земле, и их гнезда содержат от 4 до 12 яиц, окруженных пухом, сорванным с груди и живота самки. Птенцы плавают и кормятся самостоятельно вскоре после вывода из яйца. Некоторые виды, такие как североамериканская утка, гнездятся в дуплах деревьев и без проблем используют гнезда из искусственной древесины. Их птенцы могут без вреда выпрыгнуть из гнезда и вскоре войти в воду.

Bol'shinstvo vidov gnezdyatsya na zemle, i ikh gnezda soderzhat ot 4 do 12 yaits, okruzhennykh pukhom, sorvannym s grudi i zhivota samki. Ptentsy plavayut i kormyatsya samostoyatel'no vskore posle vyvoda iz yaytsa. Nekotoryye vidy, takiye kak severoamerikanskaya utka, gnezdyatsya v duplakh derev'yev i bez problem ispol'zuyut gnezda iz iskusstvennoy drevesiny. Ikh ptentsy mogut bez vreda vyprygnut' iz gnezda i vskore voyti v vodu.
