What are three criteria that Thomas Hunt Morgan was looking for in a model organism for genetic studies?
Thomas Hunt Morgan looked for a model organism that had a short generation time, produced numerous offspring, and had easily observable traits that could be studied. These criteria were important for efficient genetic studies and observations of inheritance patterns. Morgan famously chose the fruit fly Drosophila melanogaster as his model organism due to its suitability based on these criteria.
Is a Stentor Multicellular or Unicellular?
Stentor is a multicellular organism. It is a type of protist that is composed of a large, single-celled body with complex internal structures that enable it to perform various functions within the organism.
What are the observable characteristics of an Elodea leaf when viewed under a microscope?
When an Elodea leaf is viewed under a microscope, observable characteristics include the presence of chloroplasts, cell walls, and a distinct cell structure with a central vacuole. The chloroplasts appear as green structures within the cells, and the cell walls are visible as thin, rigid boundaries surrounding each cell. The cells are typically rectangular in shape and contain a large central vacuole, which may appear as a clear space within the cell.
What Onion epidermis is a suitable tissue to use for observing cellular structures with a compound light microscope because this tissue is thin enough to?
Onion epidermis is a suitable tissue for observing cellular structures with a compound light microscope because it is transparent, allowing light to pass through easily, and the cells are thin enough to view individual cells and structures such as cell walls, nuclei, and chloroplasts. Additionally, the large size of onion cells compared to other plant cells makes it easier to study their internal structures.
How does the statement all for one and one for all apply to large multicelled organmisms?
In large multicellular organisms, the statement "all for one and one for all" emphasizes the idea of individual cells working together for the overall benefit of the organism. Each cell has a specific role and contributes to the functioning of the entire organism. Cooperation among cells is essential for maintaining homeostasis and ensuring the survival and well-being of the organism as a whole.
What is a macroscopic?
Observable by the nacked eye. Involving large units or elements.
What is an example of a large unicellular organism?
An example of a large unicellular organism is the xenophyophore, a deep-sea protist that can reach sizes of up to 20 centimeters in diameter. Xenophyophores are single-celled organisms that form intricate structures on the ocean floor.

How large is the known universe?
The observable Universe has a diameter estimated at 93 billion light-years.
What are two types of large structures created by the Egyptian architects?
Two examples of large structures constructed by the ancient Egyptians are pyramids and obelisks.
What large structures were built to stargaze?
Observatorys.
Can tornadoes pick up large buildings and move them?
Not large structures such as high rise and mid rise buildings, no. However structures as large as churches have been lifted. Most structures that go airborne in a tornado disintegrate either in the air or on impact with the ground.
What are the main structures you could have observed when you removed the exoskeleton of the abdomen of a crayfish?
The large feathery structures are the gills.
How does surface area to volume ratio affects an organism?
If the surface area of the organism is small, then there is no problem with getting all the oxygen needed. If the surface area of the organism is large, therefore a special respiratory surface is needed. An example is lungs, gills. The ratio of surface area to volume in a small organism is greater than the ratio in a large organism.
What are two types of large structures created by the Egyptians?
Pyramids and other large spiritually monuments.
