This disease in children is known as Rickets which is more severe. Which of the following characteristics first developed in reptiles - Toppr Therefore, returning it to the reduced state. Which hominid is considered to be the handyman by being the first to use tools? notochord A dorsal supporting rod that is located just below the nerve cord. warm-blooded (maintains a constant body temperature). two separate atria and one shared ventricle that allow oxygen-rich and oxygen-poor blood to mix. -well-developed brain. These characteristics allowed them to move more easily on land and to find food. This vitamin is an antioxidant and is important in having strong immunity and healthy skin. -Birds, unlike mammals, require no parental care. -having a bladder. Ch. 31 Flashcards | Chegg.com In powered flight, the animal uses muscular power to generate aerodynamic forces to climb or to maintain steady, level flight. b. hypnosis The largest group of vertebrates is the A. mammals. Which of the following is not a true statement? -hard, horny scales -internal fertilization by means of a penis -shelled egg -being cold-blooded -well-developed lungs. In contrast to gliding, which has evolved more frequently but typically gives rise to only a handful of species, all three extant groups of powered flyers have a huge number of species, suggesting that flight is a . The pulmonary veins are large blood vessels that receive oxygenated blood from the lungs.There are four pulmonary veins, two from each lung. Kieran can say that acquisition has occurred as soon as the parrot greets him in response to his entry. These animals are well-adapted to a wide variety of habitats, and they are able to take advantage of many different food sources. Reptiles first appeared during the late Carboniferous period, about 300 million years ago. Any object moving through air experiences a drag force that is proportion to surface area and to velocity squared, and this force will partially counter the force of gravity, slowing the animal's descent to a safer speed. b. (a) What is a vertebrate? List the major groups of extant (living) vertebrates, along with their distinguishing characteristics. -a larger brain (cerebral) volume. Animals having an amniotic shell are called as amniotes. a. The red blood cells give thebloodits characteristic color and carry oxygen from the lungs to the tissues. Pterosaurs were the next to evolve flight, approximately 228 million years ago. Successful flights for gliding animals are achieved through 5 steps: preparation, launch, glide, braking, and landing. [15] Soaring is very energetically efficient. The characteristics of child development stages. b.) Which Of These Characteristics First Developed In Reptiles? What is the main characteristic that is common in amphibians but not in mammals? To learn more about Artificial selection, refer to the link: Compare and contrast the characteristics of mosses and ferns. In the forests of Southeast Asia, the dominant canopy trees (usually dipterocarps) are taller than the canopy trees of the other forests. [11] Various factors produce these disparities. Reptiles are found in a wide variety of habitats, including deserts, rainforests, and even the Arctic. The first reptiles probably laid eggs. Which of the following vertebrate classes has the greatest number of species? This has made the flight of organisms considerably harder to understand than that of vehicles, as it involves varying speeds, angles, orientations, areas, and flow patterns over the wings. Which of the following is part of a male flower? -Birds lack a septum between the ventricles; mammals have such a septum. 2. The other body parts develop later on. Include several animal phyla. They play an important role in keeping populations of different species in balance, and their behavior affects a great number of other species. It acts a peroxyl radical scavenger which disables the production of free radicals in the tissues which are damaging to the body. [16] There are two basic aerodynamic models of insect flight. -adult is radially symmetrical -locomotion by muscles -endoskeleton of spiny, calcium-rich plates -larva is bilaterally symmetrical -both sexual and asexual reproduction, Sea stars and sea urchins operate their tube feet by. -dogfish shark. Following are the important characteristics of the animals belonging to Class Reptilia: These are creeping and burrowing terrestrial animals with scales on their body. What is an ancestral characteristic for all placental mammals? (e) Animals with lungs. As you might expect, etymology can help describe the animal group. Which characteristic is common to all the modern representatives of all major reptilian lineages (turtles, lepidosaurs, crocodilians, and birds)? Get access to this video and our entire Q&A library, What is an Amniotic Egg? 7.5336, The transit service may refuse transport of an individual with a disability if that person does not have a personal care attendant. What are the Child Development Stages? - CPD Online College This animal would best fit into the phylum: a. Chordata b. Mammals are characterized by the presence of milk-producing mammary glands for feeding their young, a neocortex region of the brain, fur or hair, and three middle ear bones. Powered flight is very energetically expensive for large animals, but for soaring their size is an advantage, as it allows them a low wing loading, that is a large wing area relative to their weight, which maximizes lift. The eggs would have been protected from the dry air and from predators. Forest structure and distance between trees are influential in the development of gliding within varying species. This occurred during the Devonian period, approximately 420 million years ago. Globally, smaller gliding species tend to have feather-like tails and larger species have fur covered round bushy tails,[10] but smaller animals tend to rely on parachuting rather than developing gliding membranes. These modes of locomotion typically require an animal start from a raised location, converting that potential energy into kinetic energy and using aerodynamic forces to control trajectory and angle of descent. they are dependent upon water for external fertilization. a) water vascular system b) notochord c) tube feet d) pentaradial symmetry in adult e) endoskeleton of calcium carbonate plates and spines. Which of the following sequences correctly represents vertebrate evolution? Most animals with backbones (vertebrates) have a similar body plan: skull, ribs, two pairs of limbs, and a tail. Reptiles are ectothermic, meaning that they rely on external sources of heat to regulate their body temperature. Which of These Characteristics First Developed in Reptiles? - Nahf The first reptiles were probably cold-blooded. Which statement is NOT true about echinoderms? -Osteichthyes -Amphibia -Reptilia -Aves -Mammalia, Vertebrates possessing a four-chambered heart are. This skin provided protection from the sun, predators, and the elements. There are four main characteristics that first developed in reptiles: the amniotic egg, lungs, legs, and scales. That is, what characteristic appeared in the evolution of mammals that makes this group of species share a common ancestor, most likely with that characteristic. What are the characteristics of the Phylum Chordata? Usually the development is to aid canopy animals in getting from tree to tree, although there are other possibilities. Although (b), scales on the skin, is a feature that differs between amphibians and reptiles, many insects are also considered to have scaly skin. Learn Test Match Created by natasha_fusilier Terms in this set (91) chordates Animals possessing a notochord, a hollow dorsal nerve cord, pharyngeal slits, an endostyle, and a post-anal tail for at least some period of their life cycle. What allosteric regulators are responsible for the reciprocal regulation of glycolysis and gluconeogenesis? Adult tunicates lack all the characteristics that distinguish chordates from members of other phyla. A third key characteristic of reptiles is the development of lungs. It reacts with the free radical and forms a tocopheryl radical which is reduced by a hydrogen donor. D. eels. The experiment involved the unconditioned and conditioned stimuli and responses of classical conditioning. reptiles, like amphibians, were successful in this transition due to a number of adaptations. At this time, the Earth was going through a major transition, as the forests that had covered the land for millions of years were gradually replaced by open plains. Protected from the harmful effects of free radicals, often referred to as reactive oxygen species (ROS). Reptiles | OpenStax Biology 2e - Lumen Learning Select one: a. amniotic egg b. scales on the skin c. a four-legged body d. a skull and vertebral column e. animals living on land Feedback The correct answer is: amniotic egg Question 2 The word "tetrapod" means "four feet" and includes all species alive today that have four feet but this group also includes many animals that don't have four feet. This will generate lift force vector pointing forwards and upwards, and a drag force vector pointing rearwards and upwards. Because the animal is in motion, there is some airflow relative to its body which, combined with the velocity of its wings, generates a faster airflow moving over the wing. B. antennae, six legs, and mandibles. (a) Amniotic egg. Which of the following characteristics is/are associated with amphibians? \\ A. amniotic egg: amphibians, reptiles \\ B. radial body plan: flatworms, Cnidarian medusae \\ C. embryonic notochord: bony fishes, larval amphibians \\ D. end. They also developed a more efficient respiratory system. The exoskeleton is made up of bony tissue. They can travel long distances without resting and can maintain a high level of activity for extended periods of time. A) lancelets B) tunicates C) amphibians D) mammals E) reptiles, Select the best answer. B. vertebral columns. while there were other groups of animals that were also successful in this transition, it was the unique characteristics of reptiles that allowed them to become the dominant group of terrestrial animals. As the reptiles evolved, they became better adapted to living on land. -opposable thumb and sometimes large toe. Unlike most air vehicles, in which the objects that generate lift (wings) and thrust (engine or propeller) are separate and the wings remain fixed, flying animals use their wings to generate both lift and thrust by moving them relative to the body. Paired lungs are characteristic of a. spiders b. all birds c. all fishes d. all amphibian life stages e. all insects. The lower abundance of insect and small vertebrate prey for carnivorous animals (such as lizards) in Asian forests may be a factor. Caroline's manager notices that she exhibits an internal locus of control when she speaks about her work. Biologists use two types of classification systems, the Linnaean and the phylogenetic. -rapid postnatal maturation. While amphibians were the first vertebrates to invade land, they still rely on fresh water for reproduction and to complete the larval portion of their life cycle. One suggestion is that wings initially evolved from tracheal gill structures and were used to catch the wind for small insects that live on the surface of the water, while another is that they evolved from paranotal lobes or leg structures and gradually progressed from parachuting, to gliding, to flight for originally arboreal insects.[13]. cough and cold medicines and diet and sleep aids. Based on the phylogeny of vertebrates below, which of the following statements are true? Larval tunicates differ from adults in all but one of the following ways. a. reptiles b. lancelets c. mammals d. bony fishes. Which of these characteristics first developed in reptiles? By this time . How did the development of certain characteristics in reptiles allow them to adapt to and thrive in different environments? After enough repetitions, Little Albert began to cry just by seeing the rat. -feathers -air sacs -variable body temperature -hard-shelled egg -four-chambered heart. a) hard, horny scales b) internal fertilization c) shelled egg d) ectothermic physiology e) more advanced skeleton. The first reptiles were probably descended from amphibians. What are some other adaptations the differentiate the reptiles from the amphibians (frogs, toads, and salamanders)? Learn Test Match Created by dansbyt Terms in this set (20) Which of these is NOT associated with a roundworm infection? Vertebrates without jaws would be the A. rays. Amniotic eggs are enclosed in a membrane, called the amnion, which protects the developing embryo from the environment. Animals that have evolved aerial locomotion. -opposable thumb -fingernails -usually single birth -extended period of parental care -expanded hindbrain, Which reflect(s) general trends in primate evolution? 1 Which of these characteristics first developed in reptiles Select one parental care of eggs. (a) What is the importance of the amniotic egg in vertebrate evolution? a. (b) Scales on skin. Identify the four distinguishing features that all chordates have. Scales are the tough, protective outer layer of skin that reptiles have. Although adult tunicates are stuck to the ocean bottom, they are considered early relatives of vertebrates because, Which of the following is NOT a distinguishing characteristic of vertebrates? -Mollusca. [11] In Australia, many mammals (and all mammalian gliders) possess, to some extent, prehensile tails. Due to these adaptations, reptiles were able to successfully compete with other terrestrial animals, and ultimately dominate the terrestrial environment. Within each lineage there are a range of gliding abilities from non-gliding, to parachuting, to full gliding. View Homework Help - SCIENCE 91161 Cell Biology Class Questions 17.pdf from SCIENCE 9116 at University of Technology Sydney. Once the armies were on the move, it became increasingly difficult to control them, and the war escalated rapidly. Shortcuts What characteristics first developed in reptiles that allowed them to be successful in terrestrial environments? a. classical conditioning Their eggs do not have an amnion which prevents them from drying out. Few of these features are obvious in adult chordates. -Chordates have bilateral symmetry. blood returns to the heart via the _____. [7] Mammals tend to rely on lower glide ratios to increase the amount of time foraging for lower energy food. It is callednaturalistic observation. Specifically in gliding mammals, there are 3 types of gliding paths respectively being S glide, J glide, and "straight-shaped" glides where species either gain altitude post launch then descend, rapidly decrease height before gliding, and maintaining a constant angled descent. -Sea squirts are invertebrate chordates. Evidence for evolution of amphibians supports the most common ancestor as a. a sturdy-finned, shallow-water lobe-finned fish b. an armored, jawed placoderm c. an early ray-finned fish d. a lizard with 4 limbs e. a lamprey without pectoral or pelvic fins. These characteristics allowed them to move more easily on land and to find food. This was perceived as a threat by the other European powers, who then started to mobilise their own armies in response.
