Motile structures such as flagella or pseudopods are present only in certain gamete stages.

Motile forms have two unequal flagella, which may have fine hairs and are anchored by a multilayered system of microtubules, both of which are similar to forms found in some green algae.

* Motile by polar flagella, or nonmotile

Motile sperm are also produced by many protists and the gametophytes of bryophytes, ferns and some gymnosperms such as cycads and ginkgo.

Motile sperm cells of algae and seedless plants.

Motile, with either unipolar or bipolar flagella, the organisms have a characteristic spiral / corkscrew appearance ( see photo ) and are oxidase-positive.

* Motile unicellular algae.

Motile cells typically have cilia restricted to the ventral surface, or some part thereof, arising from monokinetids with a characteristic ultrastructure.

At the end of May, John Motile, an acquaintance of Bernardo, also reported Bernardo as a possible murder suspect.

Motile marine animals are commonly called free-swimming.

Motile strains have a single flagellum & pili.

Motile sperm cells of algae and seedless plants.

Motile sperm cells typically move via flagella and require a water medium in order to swim toward the egg for fertilization.

It is an amazing fact that in some species this will happen while the summer is still in full swing, for instance, in August.

The loss of carnivorous species near the top of the food chain will upset the delicate ecosystem balance and may cause dramatic increases in opportunistic species.

This facilitation will not go so far as to protect an entire species, however.

Many defoliated forest areas were quickly invaded by aggressive pioneer species, such as bamboo and cogon grass, which make it unlikely the forests will be able to regenerate.

The amount of protection provided by any one antioxidant will also depend on its concentration, its reactivity towards the particular reactive oxygen species being considered, and the status of the antioxidants with which it interacts.

and reiterates in no uncertain terms: " Nothing, then, which is not a species of a genus will have an essence – only species will have it ...."

Many primate and bear species will adopt a bipedal gait in order to reach food or explore their environment.

" All will be released into the wild near Mount Kenya. In 2004 Woburn Safari Parks ' Dr. Jake Veasey ; the Head of the Department of Animal Management and Conservation at Woburn Safari Park and a member of the European Association of Zoos and Aquariums Population Management Advisory Group, with the assistance of Lindsay Banks took over responsibility for the management and coordination of the European Endangered species Programme ( EEP ) for the eastern bongo.

While most species of North American red oak are unsuitable for construction of bokken, there are some Asian species of red oak that have a significantly tighter grain and will be able to withstand repeated impacts.

The exact value of the concentration of a truly dissolved species will thus depend on the experimental conditions applied to separate it from the colloidal particles also dispersed in the liquid.

In reality, as actual combustion reactions come to equilibrium, a wide variety of major and minor species will be present such as carbon monoxide and pure carbon ( soot or ash ).

CITES Animals Committee 26: The 26th meeting of the CITES Animals Committee will address a number of agenda items, including sharks, snakes, sturgeons, corals, and listing criteria for commercially exploited aquatic species.

Whether or not a certain cycloaddition would proceed depends on the electronic orbitals of the participating species, as only orbitals with the same sign of wave function will overlap and interact constructively to form new bonds.

* Some crustaceans, such as the coconut crab, though mainly omnivorous, will prey on turtle hatchlings, smaller crabs species, rats, and carrion

The coyote will also target any species of bird that nests on the ground.

Both species will kill each other's pups, given the opportunity.

And find in the answer a license to be a variant of the human species.

It seems to me that the first human being to reach one of these planets may well learn what it is to be a truly great and noble species ''.

There must be several dozen species in the United States alone.

Finally, it is suggested that in many respects the horse lung may be anatomically more comparable to that of the human than any other presently known species.

They have a muscular tongue which in many species can be protruded.

The forelimbs may be partially developed and the hind limbs are rudimentary in pond-living species but may be rather more developed in species that reproduce in moving water.

The presence of a particular species in an area may be more easily discerned by its characteristic call than by a fleeting glimpse of the animal itself.

In 2006 there were believed to be 4, 035 species of amphibians that depended on water at some stage during their life cycle.

Of these, 1, 356 ( 33. 6 %) were considered to be threatened and this figure is likely to be an underestimate because it excludes 1, 427 species for which there was insufficient data to assess their status.

A number of causes are believed to be involved, including habitat destruction and modification, over-exploitation, pollution, introduced species, climate change, endocrine-disrupting pollutants, destruction of the ozone layer ( ultraviolet radiation has shown to be especially damaging to the skin, eyes, and eggs of amphibians ), and diseases like chytridiomycosis.

Note that the acid can be the charged species and the conjugate base can be neutral in which case the generalized reaction scheme could be written as HA < sup >+</ sup > H < sup >+</ sup > + A.

A more or less typical monocotyledon, the species can be recognized by its shortly branched inflorescence covered with branched hairs ( giving rise to the common name of Lamb's-tail ).

A number of species have come to be considered invasive, including, most notably in North America, dandelion, which was originally introduced by European settlers who used the young leaves as a salad green.

Flowers across the Apiaceae are fairly uniform and are usually perfect ( hermaphroditic ) and actinomorphic, but some are andromonoecious, polygamomonoecious, or even dioecious ( as in Acronema ), with a distinct calyx and corolla, but the calyx if often highly reduced, to the point of being undetectable in many species, while the corolla can be white, yellow, pink or purple.

( If the condition is thought to be cellulitis rather than abscess, consideration should be given to possibility of strep species as cause that are still sensitive to traditional anti-staphylococcus agents such as dicloxacillin or cephalexin in patients able to tolerate penicillin ).

A relation can be both symmetric and antisymmetric ( e. g., the equality relation ), and there are relations which are neither symmetric nor antisymmetric ( e. g., the " preys on " relation on biological species ).

These snails cling solidly with their broad muscular foot to rocky surfaces at sublittoral depths, although some species such as Haliotis cracherodii used to be common in the intertidal zone.
