Answer:

D). Four haploid cells.

Explanation:

Meiosis is a type of cell division, which leads to formation of four daughter cells from a single parent cell, having half of the number of chromosomes as present in parent cell.

Cells formed by meiosis are haploid cells as they contain half of the amount of genetic material as present in diploid parent cells.

Meiosis takes place in germ cells (gamete forming cells) and forms haploid male gametes (sperms) and female haploid gametes (ova) that combine together during fertilization to form diploid zygote.

Thus, the correct answer is option (D).

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.

Suppose you have identified a type of lizard that seems to have acquired a mutation in which hindlimbs are absent. Which gene, a
slavikrds [6]

Answer:

Sonic Hedgehog.

Explanation:

Sonic hedgehog is a secreted protein that in humans is encoded by the SHH gene. It is the best studied ligand of the hedgehog signaling pathway, others being desert hedgehog (DHH) and Indian hedgehog (IHH). It plays a key role in the development of animals, from insects to mammals. In vertebrates, it is involved in organogenesis, including the growth of digits on limbs and the organization of the brain.

Sonic hedgehog has also been shown to act as an axonal guidance cue. It has been demonstrated that SHH attracts commissural axons at the ventral midline of the developing spinal cord. Specifically, SHH attracts retinal ganglion cell (RGC) axons at low concentrations and repels them at higher concentrations
