Definition: A heavy, shiny mineral that contains uranium and radium, often used as a source of these elements.

Example: Uranite is an important mineral for extracting uranium for nuclear energy.

Definition: A heavy, silvery-white metal that is radioactive and toxic. It is used in nuclear energy and weapons and occurs naturally in certain minerals.

Example: Uranium is used as fuel in nuclear power plants.

Definition: This term describes something that is connected to uranium, particularly when it has a lower valence than other compounds of uranium.

Example: The chemist studied the properties of uranous compounds in the laboratory.

Definition: A chemical ion consisting of uranium and oxygen, specifically with a charge of +2.

Example: The scientist studied the properties of uranyl in the laboratory.

Definition: A type of enzyme that helps break down urea into ammonia and carbon dioxide, commonly found in certain bacteria and plants.

Example: The urase enzyme is essential for the nitrogen cycle in soil.

Definition: A colorless compound that is produced when the body breaks down proteins. It is found in urine and is important for removing nitrogen from the body.

Example: The doctor tested the patient's urine for urea levels to assess kidney function.

Definition: Relating to a chemical compound found in urine and used in fertilizers and some medicines.

Example: The scientist studied the ureal properties of the new fertilizer.

Definition: A type of enzyme that helps break down urea into other substances, specifically ammonium carbonate.

Example: Urease is important in the nitrogen cycle as it helps convert urea into usable forms of nitrogen for plants.

Definition: A type of spore that is produced by a specific structure in certain fungi, particularly those that cause plant diseases.

Example: The urediniospore is crucial for the life cycle of some plant pathogens.

Definition: A type of spore produced by certain fungi, particularly those in the order Uredinales, which are involved in the life cycle of rust fungi.

Example: The urediospore is crucial for the reproduction of rust fungi, allowing them to spread and infect plants.
