These 543-million-year-old embryos support the emergence of some aspects of arthropod development earlier than previously thought in the late Proterozoic.

These embryos had defects similar to those treated with thalidomide.

These injected blastocysts are then implanted into a pseudo pregnant female surrogate mouse which will bring the embryos to term and give birth to a mouse whose germline is derived from the donor mouse's ES cells.

These in their turn would have collided to create a third generation of fewer but even larger embryos.

These female sharks are speculated to be taking advantage of the warmer water to speed their growth or that of their embryos.

These include egg-laying, ovoviviparity, and true vivipary where the mother is connected to the developing embryos via a placenta-like structure.

These studies showed that the gene is required for normal development of the brain and spinal cord and that the morphological defects seen in mutant embryos, such as failure to close dorsal regions of the neural tube during development, appeared secondary to expansion of ventral and reduction of dorsal identities in the developing neural tube.

These screens, which led to her winning the Nobel Prize in 1995 along with developmental geneticist Edward B. Lewis, identified genes that control the segmentation pattern of Drosophila melanogaster ( fruit fly ) embryos.

These embryos are sedentary for 3 – 7 days, and in that time grow to about 4. 5 to 5 mm in length.

These endophytes are asexual, seed-borne symbionts of cool-season grasses, and grow intercellularly throughout the aerial tissues of their hosts, including shoot apical meristems, leaf sheaths and blades, inflorescences, seeds and embryos.

These embryos can be harvested for patient matching embryonic stem cells.

These hormones are commonly believed to be created in the testes, but they nevertheless still appear to be produced in male embryos lacking testes.

John Paul II states, " These techniques, insofar as they involve the manipulation and destruction of human embryos, are not morally acceptable, even when their proposed goal is good in itself.

:" These techniques, insofar as they involve the manipulation and destruction of human embryos, are not morally acceptable, even when their proposed goal is good in itself.

These dead embryos then serve as food for their sisters when they emerge from their eggs.

These can also move a short distance but at right angles to the tappets.

These are not used in amoeboid movement, but are stiff skeletons on which organelles are supported or can move on.

These infections may appear from the patient not being able to move around, and being confined to the bed.

These bacteria move by spinning the whole cell, which is shaped like a corkscrew.

These conflicts forced him into an anachronistic itinerant existence, as he had to move his court between various places through the years, residing in Graz, Linz and Wiener Neustadt.

These four ' Quadruplex ' signals are then sent to the control surface actuator, and the surface begins to move.

These include the choice over whether to adopt a current standard, or move towards a more neutral, but artificial one.

These ions move through the channel pore single file nearly as quickly as the ions move through free fluid.

These cyclonic disturbances generally move eastward from over the Mediterranean Sea several times a month and result in sporadic precipitation.

These first engines were used to power pumps and produced only reciprocating motion to move the pump rods at the bottom of the shaft.

These angels are described as having solid black eyes, having a shoulder span measured in miles, and carrying hammers " so large, that if all of mankind tried at once to move them a single inch, they would fail ".

These functions allow the Amiga to move GUI windows around the screen rapidly as each is represented in graphical memory space as a rectangular block of memory which may be shifted to any required screen memory location at will.

These shows might travel through country towns or move from corner to corner along busy London streets, giving many performances in a single day.

These weakly bound electrons can move about in the crystal lattice relatively freely and can facilitate conduction in the presence of an electric field.

These young mites move about on the skin and molt into a " nymphal " stage, before maturing as adults, which live three to four weeks in the host's skin.

These channels are specific to calcium and only allow the passage of calcium to move through.

* To All Who These Presents Shall Come, Greeting: Know Ye, that in consequence of propositions of peace, or cessation of hostilities, being submitted to me, as Commandant of the California Battalion of the United States forces, which have so far been acceded to by me as to cause me to appoint a board of commissioners to confer with a similar board appointed by the Californians, and it requiring a little time to close the negotiations ; it is agreed upon and ordered by me that an entire cessation of hostilities shall take place until to-morrow afternoon ( January 13 ), and that the said Californians be permitted to bring in their wounded to the mission of San Fernando, where, also, if they choose, they can move their camp to facilitate said negotiations.

These close defenders always position themselves relative to the disc, meaning that they have to move quickly as it passes from handler to handler.

These contacts usually consist first of the bump or pass so that the ball's trajectory is aimed towards the player designated as the setter ; second of the set ( usually an over-hand pass using wrists to push finger-tips at the ball ) by the setter so that the ball's trajectory is aimed towards a spot where one of the players designated as an attacker can hit it, and third by the attacker who spikes ( jumping, raising one arm above the head and hitting the ball so it will move quickly down to the ground on the opponent's court ) to return the ball over the net.

These typically move slowly, only several meters per year, but occasionally move faster.

These chains can move independently relative to each other, which lets the material change shape.

These ghosts are particularly bothersome since they move and behave like the normal targets ( which they echo ), and so the receiver has difficulty in isolating the correct target echo.

These electron-hole pairs can only move along the surface.

These birds can raise 1-2 broods of 12-16 eggs per brood annually.

These cells then become vacuolated and are known as brood capsules, which are the parts of the parasite from which protoscolices bud.

These adaptations include brood cycles synchronized with the bloom period of local flora, forming a winter cluster in colder climates, migratory swarming in Africa, enhanced foraging behavior in desert areas, and numerous other inherited traits.

These eggs then hatch into larvae, which cause the wax cells to expand isometrically into a clump of brood cells.

These species then brood the young inside their mantle cavity, eventually releasing them into the water column as veliger larvae or as crawl-away juveniles.

These species are obligate brood parasites, meaning that they only reproduce in this fashion.

These fledge after 40 – 50 days, become independent usually a few weeks thereafter, and may raise their first brood the next spring.

These fledge after 40 – 50 days, become independent usually a few weeks thereafter, and may raise their first brood the next spring.

Outside the breeding season they form compact flocks of 3 to 30 birds, composed of family parties ( parents and offspring ) from the previous breeding season, together with any extra adults that helped to raise a brood ( see below ) These flocks will occupy and defend territories against neighbouring flocks.

These insects are normally referred to as " kleptoparasites ," rather than as " brood parasites.

These cells collectively are called " capped brood.

These birds do best in the forest interior, where they are less exposed to predators and brood parasitism by the Brown-headed Cowbird.

These birds will often lay their large eggs overtop the existing brood, causing the parents to feed the cowbird which will ultimately starve the infant Vireos.

These new females take up most of the colony's work duties, foraging, caring for brood, and maintaining the structure of the nest.

These fish are mouthbrooders ; the female lays her eggs on the surface of rocks and then scoops them into her mouth where they brood for 18 days before being released.

These were probably the descendents of Longhorn brood cows and Hereford bulls.

These pots are often arranged around a central set of horizontal brood combs, where the larval bees are housed.
