After hatching the chick is brooded by a parent until it is large enough to thermoregulate efficiently, and in some cases defend itself from predation.

After hatching, the larvae swim for a short time and then settle on a surface.

After hatching, the ducklings jump down from the nest tree and make their way to water.

After hatching, chicks leave the nest with their mother within 24 hours ; they are already able to dive and feed themselves, although they remain with their mother for another five weeks.

After the last egg has been laid, both parents incubate for about 19 – 21 days until hatching, and feed the young birds.

After hatching, they are led away from the nest and may move to habitats such as sewage farms, lake edges, marshes and mudflats.

After hatching the chicks are dependent on getting warmed by the hen.

After hatching, the female cares for and feeds the chicks for the first 8 – 14 days of life, and also during bad weather after that.

After hatching, young require 4 – 6 weeks before fledging the nest.

After hatching, some species overwinter in the subterranean nest, emerging the following spring.

After hatching both parents feed the young, which fledge 10 to 12 days later and are dependent on parental care for about another month.

After hatching, the caterpillars tend to wander around before finally settling on eating the particular plant they are on.

After hatching, the parasite larva kills the host larva, unless the female parasite has already done so, and then consumes the provisions.

After hatching, young remained in the family group and were fed by the adults for three months, by which time they appeared adult.

After hatching, the young are brooded for 16 to 23 days by the female, while the male defends the territory and catches food.

After 28 to 35 days, the eggs hatch over 2 to 4 days ; the nestlings are altricial at hatching.

After hatching the female broods the young for a few days, and for up to two weeks at night.

After hatching, they transform into frogs and are ready to leave the water in about eight weeks.

** After the supply of war-surplus frogman's drysuits ran out, free-swimming diving suits were not readily available to the general public, and as a result many scuba divers dived with their skin bare except for swimming trunks.

After the asexual reproduction stage cercaria ( another free-swimming larva ) are generated in large quantities, which then leave ( shed into the environment ) the snail and must infect a suitable vertebrate host.

After the formation of the endometrial cups and early placentation is initiated ( 35 – 40 days of gestation ) the terminology changes, and the embryo is referred to as a fetus.

After fertilization, an embryo develops, nourished by nutrients contained in the egg.

After fertilization, the newly formed zygote then begins to divide through meiosis, forming an embryo, which implants in the female's endometrium.

After the Reformation the skull was taken to the exhibition rooms of king Frederik III in Copenhagen, where it was on exhibit along with the petrified embryo a woman had carried inside her for 28 years, as well as other monstrosities the king had collected — until it was transferred to Copenhagen's National museum.

After the 1950s, with the DNA helical structure being unravelled and the increasing knowledge in the field of molecular biology, developmental biology emerged as a field of study which attempts to correlate the genes with morphological change, and so tries to determine which genes are responsible for each morphological change that takes place in an embryo, and how these genes are regulated.

After many mitotic divisions, this single cell forms a blastocyst ( an early stage embryo with about 100 cells ) with almost identical DNA to the original organism.

After fertilization ( joining of the sperm and egg cell ), the zygote develops into an embryo ( young sporophyte ).

After circulating through the capillaries of the villi, the blood is returned to the embryo by the umbilical veins.

After fertilization, the ovule contains a diploid zygote and then embryo of the next sporophyte generation.

After fertilization, the nucellus may develop into the perisperm that feeds the embryo.

After two months, the embryo measures long and has well-developed external gills.

After rallying the inmates and preparing the defense against the creature, Ripley discovers the embryo of an Alien Queen growing inside her, thus realizing why she had not been attacked.

After nine days, the eggs are held to a light to reveal the embryo inside.

After embryo loophole was closed, Coburn lifted his hold on the bill.

After fecundation, this gamete will generate an embryo with three copies of chromosome 21.

After 22 failed attempts at reconstituting the DNA using a duplicate X chromosome, the 23rd sample yields a viable sample to combine with an embryo.

After Kaufman left, Evans continued his work, upgrading his laboratory skills to the newest technologies, isolated the embryonic stem cell of the early mouse embryo and established it in a cell culture.

After their four-year old son dies, a couple take part in an experiment to clone a new embryo from their dead son's brain and nerve cells, and implant it as a new pregnancy.

After retrieval, the ova are fertilized by the sperm of the male partner ( or sperm donor ) in the laboratory, and, after several days, the best resulting embryo ( s ) is / are placed in the uterus of the recipient, whose uterine lining has been appropriately prepared for embryo transfer beforehand.

After the formation of the third quartet, one of the macromeres initiates maximum contact with the overlying micromeres in the animal pole of the embryo.

After mating, the embryo enters a state of delayed implantation through the winter, so that a single young is born in the summer.

After early research on the development and histogenesis of muscles, professor Godlewski's scientific interests focused on regeneration and mechanisms regulating the process of fertilization, as well as early embryo development, blastulation and gastrulation.
