What are some types of organisms that no longer live today?
Some examples of organisms that no longer exist today include dinosaurs, woolly mammoths, and passenger pigeons. These species have gone extinct either due to natural causes or human activities.
Did organisms that require oxygen exist before photosynthetic organisms?
It would be impossible for oxygen requiring organisms to exist before photosynthetic organisms because there was not oxygen in the atmosphere for these organisms to breathe. Photosynthetic organisms take carbon dioxide and water in and create oxygen as waste. Before these photosynthetic organisms existed there was not enough or any oxygen in the atmosphere for organisms requiring oxygen to survive.
What is the small unit of life that can exist as a separate entity?
The small unit of life that can exist as a separate entity is called a cell. Cells are the basic building blocks of all living organisms, capable of performing essential life functions independently. They can exist as single-celled organisms, like bacteria and protozoa, or as part of multicellular organisms, where they work together to form tissues and organs.
Which layer supports living organisms?
The layer that supports living organisms is the biosphere, which encompasses all regions on Earth where living organisms can exist. It includes the atmosphere, hydrosphere, and lithosphere where life is found.
Explain why no organism can exist alone?
No organism can exist alone because all living organisms are interconnected and interdependent within their ecosystems. Organisms rely on each other for resources such as food, shelter, and in some cases, as part of their life cycles. This interconnectedness is vital for the balance and sustainability of ecosystems.
What organisms that exist as either a medusa or polyp form.?
Organisms that exist in both medusa and polyp forms belong to the phylum Cnidaria, which includes jellyfish, corals, and sea anemones. In this life cycle, the medusa form is typically free-swimming and reproduces sexually, while the polyp form is usually sessile and can reproduce asexually. Examples include the common jellyfish (Aurelia aurita) and various coral species, which exhibit these two forms at different stages of their life cycle.
When did Medusa exist?
She never existed; Medusa is a myth.
Does Medusa exist?
Short answer: No.
Did madoosa really exist?
No, Medusa does not really exist. She is a fictional character from mythology.
Did Medusa exist?

Can a woman be turned into stone if she looked into Medusa's eyes?
That is what the myth says, but it is only a myth since Medusa does not exist.
What type of cnidarians has no Medusa stage?
Anthozoans are cnidarians that do not have a Medusa stage. This class includes organisms like corals and sea anemones, which exist solely in the polyp form throughout their life cycle. Unlike other cnidarians such as jellyfish, anthozoans are primarily sessile and have a more complex body plan adapted for their specific habitats.
Can unicellular organisms exist independently?
Yes, single-celled organisms can exist independently.
Does Pegasus exist?
According to most modern beliefs, no, Pegasus does not exist. In Greek mythology, Pegasus was a winged horse that came out of Medusa when she was beheaded by Perseus.
What most freshwater hydrozoa exist only as what?
Most freshwater hydrozoa exist only as the polyp form. They never switch to the medusa form, or sexual form. This means they exist only in the asexual form.
What are some types of organisms that no longer live today?
Some examples of organisms that no longer exist today include dinosaurs, woolly mammoths, and passenger pigeons. These species have gone extinct either due to natural causes or human activities.
What are Organisms that exist only as a group of cells?
tissues
