A life cycle is a period involving one generation of an organism, whether through asexual reproduction or sexual reproduction. In regard to its ploidy, there are three types of cycles: haplontic life cycle diplontic life cycle diplobiontic life cycle (also referred to as diplohaplontic, haplodiplontic, or dibiontic life cycle) These three types of cycles feature alternating haploid and diploid phases (n and 2n). Th ...

A zygotic meiosis is a meiosis of a zygote immediately after karyogamy, which is the fusion of two cell nuclei. This way, the organism ends its diploid phase and produces several haploid cells. These cells divide mitotically to form either larger, multicellular individuals, or more haploid cells. Two opposite types of gametes (e.g., male and female) from these individuals or cells fuse to become a zygote. In the whole cycle, zygotes are th ...

Anisakis pegreffii Anisakis physeteris Anisakis schupakovi Anisakis simplex Anisakis typica Anisakis ziphidarum Anisakis is a genus of parasitic nematodes, which have a life cycle involving fish and marine mammals. They are infective to humans and cause Anisakiasis, and fish which have been infected with Anisakis spp. can produce an anaphylactic reaction in people who have become sensitized to Immunoglobulin E.

A zygote (Greek: ζυγωτόν) is a cell that is the result of fertilization. That is, two haploid cells—usually (but not always) an ovum from a female and a sperm cell from a male—merge into a single diploid cell called the zygote (or zygocyte). Animal zygotes undergo mitotic cell divisions to become an embryo. Other organisms may undergo meiotic cell division at this time (for more information refer to biological life cycles). Twins and multiple births can be mono ...

The progression of a product through these stages is by no means certain. Some products seem to stay in the mature stage forever (e.g., milk). Marketers have various techniques designed to prevent the process of falling into the decline stage. In most cases however, one can estimate the life expectancy of a product category. Marketers' marketing mix strategies change as their products goes through their life cycles. Advertising, for example, should be informative in the introduction stage, persuasive in the growth and maturity stages, ...

Queens complete development in 15.5 days, drones in 24 days and workers in 21 days for larvae and pupae stages. Only one queen is usually present in a hive. New virgin queens develop in enlarged cells through differential feeding of royal jelly by workers. When the existing queen ages or dies or the colony becomes very large a new queen is raised by the worker bees. The virgin queen takes one or several nuptial flights and once she is established starts laying eggs in the hive. A fertile queen is able to lay fertilized or unfertilized eggs. ...

Like in other Pacific salmon, its life cycle is subdivided into marine and freshwater periods; in rivers, this species lives from 1 to 3 years and can form living fresh-water forms. The sea life cycle, depending on the age of the young, continues for 2-3.5 years. In the sea, the cherry salmon feeds intensely on crustaceans, less often on young fish. On attaining sexual maturity, in its third through seventh years of life it enters rivers to spawn. Its spawning run starts earlie ...

Saturniid larvae come in a variety of shapes, sizes, and colors-- they may be smooth, fuzzy, or covered with tubercles or spines. All larvae feed on the foliage of trees and shrubs. They molt at regular intervals, usually four to six times before entering the pupal stage. Most larvae spin a silken cocoon in the leaves of a preferred host plant or in leaf litter on the ground. However, larvae of the regal moth (Citheronia regalis) and imperial moth (Eacles imperialis) burrow and p ...

The life cycle of O. volvulus begins when a parasitised female Black fly of the genus Simulium takes a blood meal. Saliva containing stage three O. volvulus larvae passes into the blood of the host. From here the larvae migrate to the subcutaneous tissue where they form nodules and then mature into adult worms over a period of one to three months. After the worms have matured they mate, the female worm producing between 1000 and 1900 eggs per day. The eggs mature internally to form stage one microfilariae, which are r ...

The life of a liverwort starts from a haploid spore, which germinates to produce a protonema, which is either a mass of filaments or thalloid (flat and thallus-like). This is a transitory stage in the life of a liverwort. From the protonema grows the gametophore ("gamete-bearer") that produces the sex organs of the liverworts. The female organs are known as archegonia (singular archegonium) and are protected by the perichaetum (plural perichaeta). The archegonia have necks called venters which the male sperm swim down. The male organs are known as antheridia (singular antheridium) and are ...

Most kinds of plants have a double portion of chromosomes in their cells (diploid, i.e. each chromosome exists with a partner that contains the same genetic information) whilst mosses (and other bryophytes) have only a single set of chromosomes (haploid, i.e. each chromosome exists in a unique copy within the cell). There are periods in the moss lifecycle when they do have a full, paired set of chromosomes but this i ...

Dinoflagellates have a peculiar form of nucleus, called a dinokaryon, in which the chromosomes are attached to the nuclear membrane. These lack histones and remained condensed throughout interphase rather than just during mitosis, which is closed and involves a unique external spindle. This sort of nucleus was once considered to be an intermediate between the nucleoid region of prokaryotes and the true nuclei of eukaryotes, and so were termed mesokaryotic, but now are cons ...

Orthopterans develop by incomplete metamorphosis. Most orthopterans madona lay their eggs in the ground or on vegetation. The eggs hatch and the young nymphs resemble adults but lack wings and at this stage are often called hoppers. Through successive moults the nymphs develop wings buds until their final moult into a mature adult with fully developed wings. The number of moults varies between species; growth is also very variable and may take a few weeks to some months depending on ...
