Which of the Following Organisms Has No Specialized Respiratory Structures
Single-celled organisms exchange gases directly across their cell membrane. Which of the following organisms has no specialized respiratory structures.
These are tracheae book-lung in arthropods pulmonary sac in prosobranch and lung in pulmonate molluscs and accessory respiratory organs in fishes.
. All aerobic organisms require oxygen to carry out their metabolic functions. They respire by the process of diffusion through the skin surface. Sponges lack complex digestive respiratory circulatory reproductive and nervous systems.
Which of the following is a selective pressure that most likely led to the convergent evolution of these respiratory structures. Minute life-forms such as protozoans exchange oxygen and carbon dioxide across their entire surfaces. The LUCA is estimated to have lived some 35 to 38 billion years ago sometime in the Paleoarchean era.
Sponges despite being simple organisms regulate their different physiological processes through a variety of mechanisms. Following are some of the examples of unicellular organisms. An advantage of gas exchange in water compared with gas exchange in air is that _____.
Insects have a highly specialized type of respiratory system called the tracheal system which consists of a network of small tubes that carries oxygen to the entire body. Thus it is the most recent common ancestor of all current life on Earth. Countercurrent exchange in the fish gill helps to maximize.
Along the evolutionary tree different organisms have devised different means of obtaining oxygen from the surrounding atmosphere. Earthworms are organisms that have no special respiratory organs. Which of the following organisms has no specialized respiratory structures.
They do not have any respiratory structures for respiration. These mechanisms regulate metabolism reproduction and locomotion. Gases are exchanged through the moist skin and capillaries where the oxygen is picked up by the hemoglobin dissolved in the blood plasma and carbon dioxide is released.
However the slow diffusion rate of oxygen relative to carbon dioxide limits the size of single-celled organisms. The unicellular organisms respire aerobically or anaerobically. The main structures of the human respiratory system are the nasal cavity the trachea and the lungs.
See Concept 425 Page. Respiration in Unicellular Organisms. The last universal common ancestor LUCA is the most recent organism from which all organisms now living on Earth descend.
Organisms that exchange gas primarily through the skin are possible choices. Which of the following organisms has no specialized respiratory structures. Which of the following organisms has no specialized respiratory structures.
The earliest evidence for life on Earth is graphite found to be biogenic in. Earthworms have no special respiratory organs. Avail 25 off on.
See Concept 425 Page earthworms. Which of the following organisms has no specialized respiratory structures. Respiratory structures are tailored to the need for oxygen.
The oxygen is picked up by the hemoglobin dissolved in the blood plasma and carbon dioxide is released. Earthworms An advantage of gas exchange in fresh water compared with gas exchange in air is that _____. Specialized Respiratory Structures in Animals Zoology.
Multicellular organisms in which diffusion distances are longer generally resort to other strategies. Simple animals that lack specialized exchange surfaces have flattened tubular or thin shaped body plans which are the most efficient for gas exchange. Therefore the correct answer is option B.
Respiration takes place in these through the moist skin and capillaries. O salmon O alligators earthworms O ants O crabs. Aquatic worms for example lengthen and flatten their bodies to refresh the external medium at their surfaces.
Mar 07 2022 1202 PM. See Concept 425 Page View Available Hint s Hint 1. The tubes in the tracheal system are made of a polymeric material called chitin.
In some land invertebrates and some aquatic invertebrates and vertebrates respiratory structures to use atmospheric oxygen developed. Which of the following organisms has no specialized respiratory structures. Ants salmon crabs earthworms alligators.
The tracheal system is the most direct and efficient respiratory system in active animals. Cnidarian organisms also have no specialized resp. The organism below is found in kingdom fungi Solved The organism below is found in kingdom fungi aUsing structures X and Y onlywhy does the organism not qualify as a plant bWhat division does the moss and liverwort belong to in kingdom plantae.
