In typical amphibian development, eggs are laid in water and larvae are adapted to an aquatic lifestyle. Frogs, toads and salamanders all hatch from the egg as larvae with external gills. Metamorphosis in amphibians is regulated by thyroxin concentration in the blood, which stimulates metamorphosis, and prolactin, which counteracts its : Amphibia, Linnaeus,

Gills For many frogs, their life cycle includes a "tadpole" or larval stage of development. Eggs are laid into ponds or lakes, and upon hatching the tadpole uses internal and external gills in order to respire within their aquatic environment.
The Respiratory Rate of Developing Amphibian with Special Reference to Sex Differentiation Article in Journal of Experimental Zoology 73(3) - April with 9 Reads How we measure 'reads'. The eggs are placed in the brood chamber, which is located dorsally beneath the carapace and which is closed by the abdominal processes (Figures and ).
Development of eggs is direct (immediate). At 20ºC, the embryos hatch from the eggs after about 1 day but remain in the brood chamber for further development (Figure ).Cited by: 2. Loss of Tadpole Structures in Frog Direct Development.
Despite the dozen independent origins of frog direct development, the different groups tend to converge on a common embryo appearance. This is due in large part to the lack of a feeding tadpole, leading to the requirement for a greatly increased yolk content of the by: Boell, E.

The Amniote Egg A necessary part of the invasion of dry-land environments by the early reptiles was the development of an egg that could be laid out of water without drying up and that could "breathe" air rather than water.
This egg, developed by the first reptiles, was the amniote egg, so named because it contains a membrane called the amnion. While the eggs, and the spermatozoa also, are very resistant to cold, they are at the same time very sensitive to warmth, so that this slight elevation of temperature has the effect of hastening development an effect that may be quite important since the temperature of the water is often quite low at the time the eggs are laid, and the ponds in.

The brine shrimp eggs will not hatch in the stomach of the child. Strong enzymes and an acid pH in the digestive tract will metabolize the brine shrimp eggs as any other food. If the egg gets into a pupil' s eyes, wash immediately with running water. The students should wash their hands after handling the brine shrimp eggs — especially before.
As far as taxonomy, frogs and toads belong to the class Amphibia and order Anura. The three Anura suborders are Archaeobatrachia, Mesobatrachia and Neobatrachia.
True frogs are part of the family Ranidae, and true toads are members of the family Bufonidae. At least 5, frog and toad species are known to exist in the world. The general body plan of a damselfly is similar to that of a dragonfly.
The compound eyes are large but are more widely separated and relatively smaller than those of a dragonfly. Above the eyes is the frons or forehead, below this the clypeus, and on the upper lip the labrum, an extensible organ used in the capture of top of the head bears three simple eyes (), which may measure Class: Insecta.
A frog breathes by changing the volume and pressure of air in its mouth while either opening or closing nostrils. Air moves from the throat to the lungs through a slit-like passage called the glottis.
Oxygen can diffuse across the linin of the mouth and into the blood. Frogs use mouth breathing for a small amount of respiration.If the sound of Abraham Trembley's somersaulting polyps or Lazzaro Spallanzani's trouser wearing frogs sounds interesting, then this is a book you will love as much as I did.
The seven signs of life are movement, respiration, sensitivity, growth, reproduction, nutrition and excretion. There are three kingdoms - animal, mineral and vegetable/5(12). All living things use a process called respiration to get energy to stay alive.
Cellular respiration in plants is the process used by plants to convert nutrients obtained from soil into energy which fuels the plants’ cellular activities. On the other hand, photosynthesis is the process where light energy is converted into chemical energy stored in glucose that can later be used in respiration/5(25).
