Answer:
Animal? Bacteria? Plant? Fungi? What do these figures represent?
2
None of the above! These organisms may be single-celled like bacteria, and they may look like a fungus. They also may hunt for food like an animal or photosynthesize like a plant. And, yet, they do not fit into any of these groups. These organisms are protists!
What are Protists?
3
Protists are eukaryotes, which means their cells have a nucleus and other membrane-bound organelles. Most protists are single-celled. Other than these features, they have very little in common. You can think about protists as all eukaryotic organisms that are neither animals, nor plants, nor fungi.

Although Ernst Haeckel set up the Kingdom Protista in 1866, this kingdom was not accepted by the scientific world until the 1960s. These unique organisms can be so different from each other that sometimes Protista is called the “junk drawer" kingdom. Just like a junk drawer, which contains items that don't fit into any other category, this kingdom contains the eukaryotes that cannot be put into any other kingdom. Therefore, protists can seem very different from one another.

Answer:
5.112 grams of simple sugar glucose is produced by the reaction of 7.50 g of carbon dioxide.
Explanation:
Moles of carbon dioxide =
According to reaction 6 moles of carbon dioxide gives 1 mole of glucose.
Then 0.1704 moles of carbon dioxide will give:
of glucose
Mass of 0.0284 moles of glucose:
0.0284 mol 180 g/mol =5.112 g[/tex]
5.112 grams of simple sugar glucose is produced by the reaction of 7.50 g of carbon dioxide.
Answer:
The difference between the energy of the reactants and the energy of the products is called the enthalpy change (∆H) of the reaction. For an exothermic reaction, the enthalpy change is always negative. In an endothermic reaction, the products are at a higher energy than the reactants.
Explanation:
Answer:
Sound waves enter the outer ear and travel through a narrow passageway called the ear canal, which leads to the eardrum. The eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear. These bones are called the malleus, incus, and stapes.
