Comprehensive Science Vocabulary and Evolution Concepts for Biology

What is the primary function of antibodies?

To bind to specific antigens, inactivating pathogens and flagging them for destruction.

What type of white blood cells produce antibodies?

B lymphocytes.

What is an antigen?

A surface structure on cell membranes that identifies cells.

What are the two types of immunity?

Active immunity and passive immunity.

What is active immunity?

Long-term immunity developed through exposure to live pathogens or vaccinations.

What is passive immunity?

Short-lived immunity acquired through the transfer of antibodies, such as from mother to child.

How do antibodies recognize pathogens?

Antibodies have a specific shape that matches the shape of their corresponding antigen.

What happens when a new pathogen enters the body?

The body needs to build a specific antibody to match the new antigen introduced by the pathogen.

What is the role of memory cells in the immune system?

Memory cells allow the immune system to remember past pathogens for quicker responses in future exposures.

What is the significance of the shape of antibodies?

The shape of antibodies is specific to each antigen, allowing them to bind effectively.

What is the difference between active and passive immunity in terms of longevity?

Active immunity is long-lasting, while passive immunity is short-lived.

What is the function of phagocytic white blood cells?

To engulf and destroy pathogens.

What are the components of blood involved in the immune response?

Red blood cells (RBCs), white blood cells (WBCs), and platelets.

What is the role of platelets in the blood?

To aid in blood clotting and stop bleeding.

What is the relationship between antibodies and vaccines?

Vaccines expose the immune system to weakened or killed pathogens to stimulate antibody production.

What is the purpose of tissue donation in relation to the immune system?

To understand potential tissue rejection due to immune responses against foreign antigens.

What are leukocytes?

Another term for white blood cells, which help control pathogens.

What is the role of eosinophils in the immune system?

To respond to allergies and parasitic infections.

What is the significance of maternal immunity?

Maternal antibodies are transferred to the unborn child through the placenta, providing early protection.

How do antibodies provide quick immunity?

Through the infusion of pre-made antibodies, offering immediate but temporary protection against pathogens.

What is the importance of the shape-specific binding of antibodies?

Each antibody can only bind to its specific antigen, ensuring targeted immune responses.

A medicine that kills bacteria.

Define bacteria.

Single-celled organisms without a nucleus.

What does 'beneficial' mean?

Helpful or advantageous.

What are biofilms?

Complex structures of multiple microorganisms.

What is camouflage?

Hiding by changing looks to blend in with surroundings.

What causes cholera?

Infection caused by microorganisms in contaminated water.

What is competition in biology?

Fighting for resources among organisms.

Define cooperation.

Helping together to achieve a common goal.

What is differential survival?

Some organisms live because they are better suited for their environment.

What is an ecosystem?

A community of interacting organisms and their environment.

Define immunity.

Resistance to infection.

What is the immune system?

The organ system involved in fighting infection.

What is an infectious disease?

A disease that spreads through contact.

What is a microbiome?

A community of symbiotic microorganisms, usually in the gut.

What is a mutation?

A change in DNA sequence.

What does it mean to observe?

To notice with your senses.

What is an outbreak?

A widespread occurrence of disease.

What is a pandemic?

Global spread of illness.

Define population density.

The amount of organisms in a specific area.

What is a predator?

A hunter or carnivore that preys on other organisms.

What does it mean to reproduce?

To produce an offspring.

What is selective pressure?

A force that impacts a population size based on some feature.

What does symbiotic mean?

Relying on another organism for survival.

What is a trait?

Physical features or characteristics of an organism.

What is transmission in biology?

The spreading of disease from one organism to another.

What is a fecal transplant?

Putting a tissue or organ from one organism into another.

What does variation refer to?

Different types of the same thing.

What is the primary method of prevention for bacterial diseases?

Do not shave water bottles, vaccinations, wash hands.

What type of medication is used to treat bacterial infections?

Antibiotics (effective only against bacteria).

What are the symptoms of Lyme disease?

Bull's-eye rash at the tick bite site, fever, fatigue, headache.

How is Lyme disease transmitted?

Ticks transmit the bacterium Borrelia burgdorferi.

What are the symptoms of Tetanus?

Lockjaw, stiffness in neck and abdomen, difficulty swallowing, fever, elevated blood pressure, severe muscle spasms.

What are the symptoms of Tuberculosis?

Fatigue, weight loss, night sweats, chills, appetite loss, bloody sputum from lungs.

What are the symptoms of bacterial meningitis?

High fever, headache, stiff neck, nausea, fatigue.

How is bacterial meningitis transmitted?

Spread in respiratory droplets from coughing and sneezing; close contact with an infected person.

What are the symptoms of strep throat?

Fever, sore throat, headache, fatigue, nausea.

How is strep throat transmitted?

Direct contact with mucus from an infected person or infected wounds.

What is the primary method of prevention for viral diseases?

Vaccinations, washing surfaces, distancing when sick.

What are the symptoms of the common cold?

Sneezing, sore throat, fever, headache, muscle aches.

What are the symptoms of influenza?

Body aches, fever, sore throat, headache, dry cough, fatigue, nasal congestion.

What are the symptoms of AIDS (HIV)?

Destruction of Helper T cells, leading to compromised immune function.

What are the symptoms of chicken pox?

Skin rash of blister-like lesions.

What are the symptoms of Hepatitis B?

Jaundice, fatigue, abdominal pain, nausea, vomiting, joint pain.

How is the common cold transmitted?

Contact with contaminated objects; droplet inhalation.

How is influenza transmitted?

Spread in respiratory droplets from coughing and sneezing.

How is AIDS transmitted?

Sexual contact, contact with contaminated blood or body fluids.

What is Darwin's theory of natural selection?

Survival of organisms best adapted to their environment.

What is the definition of adaptation in the context of natural selection?

A characteristic that helps an organism survive and reproduce in its environment.

What is the role of the environment in natural selection?

Acts as a selective pressure that chooses variations.

What is the significance of variation in a population?

More variation increases the chance of survival in changing environments.

What is the process of evolution in bacteria when exposed to antibiotics?

Bacteria with favorable variations survive and reproduce, leading to antibiotic resistance.

What is the difference between punctuated equilibrium and gradualism in evolution?

Punctuated equilibrium involves periods of stability followed by rapid changes; gradualism involves small changes over time.

What is a gene pool?

All the genes in a given population.

What is the significance of mutations in evolution?

Mutations provide the source of variation that selective pressures act upon.

What happens when a population of bacteria becomes resistant to antibiotics?

The resistant bacteria survive and reproduce, necessitating the use of new antibiotics.
