External cephalic version is a way to try to turn a baby from breech position to vertex (head-down) position while it's still in the mother's uterus. In other words, external cephalic version means turning the baby from outside of the abdomen so that it's in the head-down position.
No , sea animone is not cephalized . It lacks head and brain .
cephalized means the formation of a head, so definitely yes.
It is a vertebrate, it is ectothermic, it is bilateral, and it is cephalized. :)
it means a concentration of nerves like having a brain. Jellyfish have an equally distributed nerve net, without a specific concentration of nerves. They are not cephalized.
At some stage of their life they all have: notochord dorsal hollow nerve cord pharyngeal pouches post anal tail endoskeleton highly cephalized highly developed sense organs and brain most possess segmented vertebrae most have paired appendages closed circulatory system
No, flatworms do not have a skeletal system. They belong to a group of animals called invertebrates, which lack a true skeleton. Instead, they have a soft body that is supported by a network of muscles.
"Cephalization" means that the animal has a defined "head" region in which there is a lot of nervous tissue (such as the brain in humans). Sponges are not cephalized because they do not have defined head region nor do they have a central location for their nervous system. The nervous system in sponges is very loose because their cells generally work more individually as opposed to being commanded by a nervous system.
Mammals: Have hair or fur, and usually give birth to live young. Birds: Have feathers, beaks, and lay eggs. Fish: Have scales, fins, and gills for respiration. Reptiles: Have scales, lay eggs, and are cold-blooded. Amphibians: Have moist, permeable skin, lay eggs in water, and undergo metamorphosis.
Being bilaterally symmetrical means that an organism's body can be divided into two mirror-image halves along a central axis, while cephalization refers to the concentration of sensory organs and nerve cells at one end of the body, typically forming a head. For Dugesia, a type of planarian, these traits enhance its ability to navigate and interact with its environment efficiently. Bilateral symmetry allows for streamlined movement, while cephalization enables the organism to better detect and respond to stimuli, improving its chances of finding food and avoiding predators.
It mean what you don't what does it mean.
Mean is the average.
Bilateral symmetry allows for the animal to have directed movement, which can help when searching for food or escaping predators. Also, it allows for quicker and precise response to stimulation, since the nervous system is cephalized and much more complex than in organisms without bilateral symmetry.
