Definition: A small, flat, transparent larva of eels and some other fish, known for its long, narrow head.

Example: The leptocephalus drifts in the ocean currents before it matures into an adult eel.

Definition: A type of elementary particle that does not experience strong forces and includes particles like electrons and neutrinos.

Example: Electrons and neutrinos are examples of leptons, which play a crucial role in particle physics.

Definition: Relating to or made up of leptons, which are a type of elementary particle in physics.

Example: The leptonic interactions are fundamental to understanding particle physics.

Definition: A type of bacterium that is spiral-shaped and can live freely or as a parasite in mammals.

Example: Leptospire can cause various diseases in animals and humans.

Definition: A disease caused by bacteria that can affect both animals and humans, often leading to symptoms like fever and jaundice.

Example: Leptospirosis can be transmitted to humans through contact with contaminated water or soil.

Definition: A stage in the first part of cell division where chromosomes become visible as thin threads before they pair up.

Example: During leptotene, the chromosomes start to condense and can be seen under a microscope.

Definition: A specific area of damage or abnormal change in a part of the body, often due to injury or disease.

Example: The doctor examined the lesion on the patient's skin to determine its cause.

Definition: A lesion is an area of tissue that has been damaged or abnormal, often due to injury or disease.

Example: The doctor explained that the lesion on the patient's skin needed further examination.

Definition: Able to cause death or very serious harm.

Example: The snake's venom is lethal to small animals.

Definition: A condition or factor that causes death or is capable of causing death.

Example: The genetic mutation was found to be lethal to the developing embryos.

Definition: The quality or state of being able to cause death or serious harm.

Example: The lethality of the poison was higher than expected, leading to immediate medical intervention.

Definition: In a way that causes death or is capable of causing death.

Example: The poison was lethally effective, leading to immediate consequences.
