Hi everyone!:) i just need help with this science question in my textbook!
Katyanochek1 [597]

Answer: In a simple sense, growth in population is a good thing as it means that a species is thriving and doing well in its environment as well as reproducing at desirable rates.  However, if population continues and continues to grow it will eventually reach a cap where an environment can no longer hold more members of that specific species because there is a limit on food and places of shelter.  This leads to natural rises and declines in a species over time (which can be very predictable as well.)  A downside to rapid and sustained population growth is that if a species keeps growing and growing without reaching its cap (which happens a lot with introduced species into an environment which were not there naturally) is that they can overrun and destroy a natural environment and damage the ecosystem.  Animals and species which are already there can have their population numbers drastically reduced because of this invasive species and may be forced to move to a new area.

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.
