Cnidrians such as jellyfish and sea anemones control their bodies with a nevous system structure called a spinal cord true or false?
False. Cnidarians, including jellyfish and sea anemones, do not have a spinal cord; instead, they possess a simple nerve net that allows for basic responses to stimuli. This decentralized nervous system enables them to coordinate movements and react to their environment without a centralized brain.

What is a movable structure which allows access to a house?
A door is a movable structure that allows access to a house. It can be opened or closed to control entry into the building.
What is the structure that coordinates the complex activities of a cnidarian's body?
Cnidarians like jellyfish use muscles to contract their central bell, lightly propelling them through the water. Coral polyps and sea anemones catch food in their tentacles. When the tentacle is full of food, it curls inward toward the mouth, which sucks up all the food. Cnidarians who live in long strands in the open ocean coordinate their movement by feel. If you were a cnidarian and the cnidarian in front of you started to move left, then you would follow it left, and the one behind you would do the same. A lot of times, a larger, head cnidarian leads long strands of its friends through the water in search of food. Enjoy your day! :)
Can a program be made of only one type of control structure?
Yes, a program can be made using only one type of control structure, such as only using if statements for control flow. However, this may limit the program's functionality and readability, as different types of control structures are often needed to handle various situations and logic.
How can a jellyfish attack?
Jellyfish typically defend themselves by stinging with venom-filled tentacles when they feel threatened or accidentally come into contact with something. The stingers on their tentacles release toxins that can cause pain, irritation, and even serious reactions in humans.
What is an impounding structure?
An impounding structure is a hydraulic structure built to store water temporarily for various purposes such as flood control, irrigation, or water supply. These structures are typically dams or reservoirs that impound water in a controlled manner, releasing it as needed.
Do animals with nerve nets only have motor neurons?
Animals with nerve nets, such as jellyfish and sea anemones, do not exclusively have motor neurons. They possess a decentralized network of neurons that includes sensory neurons, which allow them to detect environmental stimuli, in addition to motor neurons that control movement. This simple neural architecture enables them to respond to their surroundings without a centralized brain.
How do jellyfish control their body temperature?
Jellyfish do not actively control their body temperature, their body temperature is that of the water surrounding them. However, they can swim and could move to, or keep themselves in, a body of water where the temperature suites their needs.
Basic control structure available in c plus plus?
The basic control structure in C++ is the if statement.
How does a jellyfish know what they are doing with no brain?
Essentially, we would presume that a jellyfish would not know or think about what it's doing. A jellyfish would go on its instincts. You have to remember that a jellyfish still has neurons, but it will not have a center of control of these neurons (which we call the brain). Thus, the jellyfish would not think to attack another fish and eat it, its neurons will simply react to the closeness of a fish and engage the jellyfish in this behaviour of killing and eating its pray. It is done pretty automatically. However, I do not know if the jellyfish would be able to learn with no brain. It can adapt to the environment, but can we make it learn specific behaviours?? So basically jellyfish are like robots, they run on autopilot.
