What else can I help you with?
How would you describe the difference in responsiveness between hydra and sponges?
Hydras typically exhibit faster responsiveness compared to sponges due to their ability to move and capture prey with their tentacles. Sponges, on the other hand, have a more limited response as they rely on water flow to filter feed and lack the ability to actively move to capture prey.
The absorption and circulation of materials in a hydra are most similar to the absorption and circulation of materials in a?
sponge. Both hydra and sponges are simple aquatic animals that rely on diffusion for nutrient absorption and lack a circulatory system. Nutrients are taken in through their body walls and transported within the body through simple diffusion rather than a dedicated circulatory system.

Can you give examples of organism that reproduce by budding?
Organisms, such as single-celled yeasts, sponges, and hydra can produce offspring by budding.
What are the differences between a hydra and a planarian?
The fertilization occurs externally
Which of the following creatures has no blood but respires 1 fish 2 earthworm 3 hydra 4 cockroach?
All animals respire, but some simple animals, such as cnidarians (anemones, jellyfish, and relatives), and sponges don't have blood.
Which animals does not have nervous system?
Sponges do not have a nervous system. They are simple aquatic animals that lack organs and have a decentralized network of cells for coordinating their activities.
What are organisms that use budding?
Examples of organisms that reproduce through budding include yeast, Hydra (a freshwater animal), and certain types of plants like cacti. Budding is a form of asexual reproduction where a new individual develops as an outgrowth from the parent organism.
How do hydras reproduce?
Budding
What is the scientific name for hydra?
Hydra or Hydra
Does hydra reproduce by fission budding mitosis or meiosis?
Hydra primarily reproduces by budding, a form of asexual reproduction where a new individual develops from an outgrowth or bud on the parent organism. This process allows hydra to rapidly increase their population size. While hydra can also reproduce sexually through meiosis, it is less common and typically occurs under specific environmental conditions.
Which two processes are most directly involved in the transport of materials in a hydra?
In a hydra, the two processes most directly involved in the transport of materials are diffusion and the movement of water through the gastrovascular cavity. Diffusion allows for the movement of nutrients and gases between the cells and the surrounding water. Additionally, the gastrovascular cavity facilitates the circulation of fluids, helping to distribute these materials throughout the organism. Together, these processes ensure effective nutrient uptake and waste removal in the hydra's simple body structure.
