holding structures deflate, the surfactant prevents the structures from sticking together. Since Serpentes have an air sack that gets completely collapsed when swallowing prey, the surfactant needs to be more fluid than what is commonly found in vertebrates to prevent the air sack from gluing itself together permanently. The surfactant would need to reduce the surface tension be below that of water. Therefore the surfactant for the air sack would require less of the disaturated phospholipids and…

properties one being their habitat, and second being they have backbones.Which is also known as vertebrates. Fish are cold blooded,water-dwelling, vertebrates. The combo of gills, fins, and factor of living in water differentiates them from other creatures. Researchers believe that there are more than 24,000 types of fish. Researchers have grouped about 22,000 breeds of these cold blooded vertebrates. I will be discussing 5 types of fish out of tons. Pollock is one type of fish that is domestic…

Frog? I believe they’re so fascinating! I have never learned about a frog more interesting than this. The Coqui is only able to live in Puerto Rico and Hawaii. The genus of the Coqui with over 700 species is one of the most species geneses of vertebrates! These frogs have quite a unique way of living. I can’t wait to teach you more! Coqui Frogs originated in the lands of Puerto Rico. They can be very sensitive frogs when having to do with humidity and temperature. Puerto Rico has the right…

The two different types There are two types of eyes in the world of today. There are what one calls compound eyes and there are vertebrate eyes. Compound eyes also known as Arthropod eyes, can be traced back to an arthropod called trilobite. These ancestors didn 't have complex lenses like those of today but instead, their eyes and lenses were made of the same rock that made their skin - calcite. Compound eyes today contain many ommatidia (singular: ommatidium) which consist of a corneal lens,…

into Vermes, Insecta, Pisces, Amphibia, Aves, and Mammalia. This system was broken up by Jean-Baptiste de Lamarck, who by 1809 had identified 14 animal phyla. In 1817 Georges Cuvier created four major branches with different body plans, namely vertebrates, molluscs, articulated animals, and zoophytes. In 1874, Ernst Haeckel divided the animal kingdom into the multicellular Metazoa and the single-celled Protozoa (no longer considered to be animals). Today the classification of animals relies on…

the role of thermoregulation in tetrapods as an adaptation for life on land. [6] Enzymes serve as catalysts for chemical reactions in the body, and they function more efficiently within select temperature ranges. As such, it is advantageous for vertebrates to maintain a body temperature that is consistently within this ideal range. Thermoregulation is the maintenance of this ideal body temperature range. Aquatic habitats are naturally thermoregulatory due to the ability of water to resist…

Many of the tasks that multi-cellular organisms perform are truly inspiring, from embryogenesis to organogenesis and other developmental processes. Developmental biology covers some of the most interesting procedures of the formation and transformation of living beings. One question in particular that sparked my interest in the vast field is how certain species of animals are able to completely reform a limb after it has been entirely severed. Such a feat is completely and utterly astonishing.…

The notochord is the defining structure of the chordates, and has essential roles in vertebrate development. It is a flexible, rod-shaped structure that is in the embryonic stage of all chordates. It gives the skeletal support and is found in between the digestive tube and nerve cord. In some animal chordates lifetimes it is the main axial support in the body. The dorsal hollow nerve cord is the only feature unique to all chordates. It is located at the top of the animal, above the notochord.…

Most people are familiar with the Venus flytrap. Small and ominous-looking, the plants are commonly sold as novelties, and many a curious child (or adult) has triggered its ..……. (baneful, sinister, doomful, malevolent) traps with a pencil to see its amazingly rapid response. However, carnivory in plants is not limited to the famous Venus flytrap. In fact, there are more than 600 carnivorous plant species, and the ability to catch and digest ………(dupe, prey, victim, quest) has evolved…
