The nettle passes though two different body forms during its life cycle. The most familiar form is the medusa, while the smaller form is the larval stage. Jellyfish are either male or female. A few steps are required in order for a jellyfish to reproduce. First, the reproductive organs in the male (the gonads) develop in the lining of the gut. Second, the male releases sperm through its mouth column. Third, the sperm has to swim into the mouth of the ...

Like other eusocial bees, a colony generally contains one breeding female, or "queen"; a few thousand males, or "drones"; and a large population of sterile female workers. The female workers mature from nurse bees to become foragers. The foragers die usually when their wings are worn out after approximately 500 miles of flight. Honeybee wings beat at a rate of 12,000 beats/minute. The population of a healthy hive in mid-summer can average between 40,000 and 80,000 bees. The workers cooperate to find food and are widely believed to use a pattern of "dancing" (known as the bee dance or w ...

The Bogong moth Agrotis infusa is common throughout southern Australia. These brown to blackish moths have a wingspan of approximately 45 millimetres. Adults make lengthy migrations to spend summer months in large congregations in caves and crevices of rocks in the Australian Alps notably to the region of Mount Bogong and the Bogong High Plains in Victoria. They are attracted to lights, such as those in the Sydney and Canberra areas, at night. Large numbers may enter houses or other buildings to rest during the day. In winter, adults disperse to pastures across in ...

Like other eusocial bees, a colony generally contains one breeding female, or "queen"; a few thousand males, or "drones"; and a large population of sterile female workers. The female workers mature from nurse bees to become foragers. The foragers die usually when their wings are worn out after approximately 500 miles of flight. Honeybee wings beat at a constant rate of 230 beats per second or 13,800 beats/minute. The frequency of the wing beats was much higher than expected for an insect of this size. Honey bees make up for carrying h ...

After the eggs of the human-dwelling parasite are emitted in the faeces and into the water, the ripe miracidium hatches out of the egg. The hatching happens in response to temperature, light and dilution of faeces with water. The miracidium searches for a suitable fresh water snail (Biomphalaria glabrata, B. straminea or B. tenagophila) to act as an intermediate host and penetrates it. Following this, the parasite develops via a so-called mother-sporocyst and daughter-sporocyst generation to the cercaria. The purpose of the growth in the sna ...

Gypsy moth egg masses are laid on branches and trunks of trees, but egg masses may be found in any sheltered location. Egg masses are buff colored when first laid but may bleach out over the winter months when exposed to direct sunlight and weathering. The hatching of gypsy moth eggs coincides with budding of most hardwood trees. Larvae emerge from egg masses from early spring through mid-May. Larvae are dispersed in two ways. Natural dispersal occurs when newly hatched larvae hanging from host trees on silken threads are carri ...

Main article: Nuclear fuel cycle A Nuclear Reactor is only a small part of the life-cycle for nuclear power. The process starts with mining. Generally, uranium mines are either open-pit strip mines, or in-situ leach mines. In either case, the uranium ore is extracted, usually converted into a stable and compact form such as yellowcake, and then transported to a processing facility. At the reprocessing facility, the yellowcake is converted to uranium hexafluoride, which is then enriched using various t ...

Chlamydophila psittaci is a small bacteria (0.5 micrometres) which undergoes several transformations during its life cycle. It exists as an elementary body (EB) in between hosts. The EB is not biologically active but is resistant to environmental stresses and can survive outside outside of a host. The EB travels from an infected bird to the lungs of a non-infected bird or person in small droplets and is responsible for infection. Once in the lungs, the EB is taken up by cells in a pouch called an endosome by a process called phagocyto ...

The Boston fern is a perennial in USDA plant hardiness zones 9 through 11. Although the fern may appear totally dead due to frost, it will re-emerge in the spring. In general, the Boston Fern likes damp, but not soggy soil that is rich in nutrients. Of the common cultivated ferns, the Boston Fern is the most tolerant to drought. The fern thrives best in humid conditions, so when grown as a house plant it becomes necessary to mist the plant when relative humidity falls below around 80%. Although outdoors this plant prefers partial shade or fu ...

Sandworms begin their life as simple creatures known as sandtrout, or "Little Makers" to the Fremen. These creatures are similar to the trocophore larvae of terrestrial annelids and molluscs: simple haploid ciliated creatures. Sandtrout are drawn to water in the open desert and together multiple sandtrout will gather to encapsulate water, creating deserts safe for the adult worms. Once they have done so, they begin to make chemical alterations to the water to produce pre-spice mass, a potential water-safe nourishment for adult worms. ...

In the wild, mountain goats usually live twelve to fifteen years, with their lifespan limited by the wearing down of their teeth. In zoos, however, they can live for sixteen to twenty years. Kids are born in the spring (late May or early June) after a six month gestation period. Nannies give birth, usually to a single offspring, after moving to an isolated ledge; post-partum, they lick the baby dry and ingest the placenta. Kids weigh a little over 3 kg (about 7 lb) at birth and begin to run and climb (or attempt to do so) withi ...

The following is Lavos' instinctual life process, as it is explained in Chrono Trigger. Lavos crashes onto a planet. Upon landing on the planet, Lavos buries itself into the planet's core at incredible speed, making a nest in the core. While it sleeps in its subterranean nest, it subconciously and forcefully evolves all life on the planet, while continuously collecting DNA from every living thing in the world. Because of humanity's dominance, this may be the reason Lavos' true, inner form is humanoid.See also:

Other temperate species (e.g. the yellow hornet V. simillima or the Oriental hornet V. orientalis) may have similar cycles. In the case of tropical species (e.g., V. tropica), life histories may well differ; and in species with both tropical and temperate distributions (such as the Asian giant hornet Vespa mandarinia), it is conceivable that the cycle depends on latitude. Such information could not be found on the web. In Vespa crabro, the nest is founded in spring by a fertilized female, known as th ...

Female house mice have an estrous cycle that is 4-6 days long, with estrus itself lasting less than a day. If several females are held together under crowded conditions, they will often not have an estrus at all; if they are then exposed to male urine, they will become estrous after 72 hours. Male house mice court females by emitting characteristic ultrasonic calls in the 30kHz - 110kHz range. The calls are most frequent during courtship when the male is sniffing and following the female. However, the calls continue after mating has b ...

There are two forms in which yeast cells can survive and grow, haploid and diploid. The haploid cells undergo a simple life cycle of mitosis and growth, and under conditions of high stress will generally simply die. The diploid cells similarly undergo a simple lifecycle of mitosis and growth, but under conditions of stress can undergo sporulation, entering meiosis and producing a variety of haploid spores (showing genetic variation), ...
