The scientific word for germs are _________________
- A.
Bacteria
- B.
Microbes
- C.
Viruses
- D.
Antigens
Correct Answer
B. MicrobesExplanation
The correct answer is "microbes." Microbes is a scientific term used to refer to microscopic organisms such as bacteria, viruses, and fungi. These organisms are too small to be seen with the naked eye but can cause diseases and infections. The term "germs" is commonly used to describe these microorganisms in everyday language. Therefore, microbes is the appropriate scientific word for germs.Rate this question:

- 3.
The two parts of the immune system that rid the body of intruders are ______________ and white blood cells.
Correct Answer
antibodies
Explanation
The correct answer is antibodies. Antibodies are proteins produced by the immune system in response to the presence of foreign substances, such as bacteria or viruses, in the body. They help to neutralize and eliminate these intruders by binding to them and marking them for destruction by other immune cells, including white blood cells. Together, antibodies and white blood cells play a crucial role in defending the body against infections and maintaining overall health.Rate this question:

White blood cells surround the intruders ( microbes) and then _______ them.
Correct Answer
digest
digest
eatExplanation
White blood cells have the ability to engulf and destroy invading microbes through a process called phagocytosis. They surround the intruders and then digest them, breaking them down into smaller pieces. This enables the white blood cells to eliminate the microbes and protect the body from infection.Rate this question:

When antigens are deactivated the antibodies that were made to attack are execreted out the body.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
they remain in the body. If a similar invader reappears the antibodies are ready to attack!Rate this question:

Some antibodies can prevent a person from getting a disease more then once. This is called _________
Correct Answer
immunityExplanation
Immunity refers to the ability of the body to resist or protect against a particular disease or infection. It is achieved through the production of antibodies, which are proteins that recognize and neutralize pathogens. When a person is exposed to a disease for the first time, their immune system produces specific antibodies to fight against it. These antibodies remain in the body even after the infection is cleared, providing long-term protection against future infections by the same pathogen. This phenomenon is known as immunity, where the person becomes immune to the disease and is less likely to get it again.Rate this question:

How do antibodies prevent certain viruses from reoccuring?
- 12.
Viruses are considered non living because they reproduce by __________ living cells.
Correct Answer
invadingExplanation
Viruses are considered non-living because they reproduce by invading living cells. Unlike living organisms, viruses lack the ability to reproduce on their own. Instead, they rely on host cells to provide the necessary machinery and resources for replication. Once inside a host cell, viruses take control of the cellular machinery and use it to produce more virus particles. This process of invasion and hijacking of host cells for reproduction is a defining characteristic of viruses and sets them apart from living organisms.Rate this question:

___________________ made from small amounts of killed or weakened microbes are used to fight the diseases they cause
Correct Answer
vaccinesExplanation
Vaccines are made from small amounts of killed or weakened microbes and are used to fight the diseases they cause. By introducing these microbes into the body, the immune system is stimulated to produce a response, including the production of antibodies. This helps the body recognize and fight off the actual disease-causing microbes in the future. Vaccines have been proven to be highly effective in preventing the spread of various infectious diseases and have played a crucial role in reducing illness and mortality rates worldwide.Rate this question:
- 14.
___________________ are drugs that are used to slow the growth of bacteria or kill them without killing the bodies cells.
Correct Answer
antibioticsExplanation
Antibiotics are drugs that specifically target bacteria, either by slowing down their growth or by killing them. These drugs are designed to be effective against bacterial infections without harming the body's cells. By targeting the unique characteristics of bacteria, antibiotics can help to eliminate the infection and promote healing.Rate this question:

When we are young bones are made up of calcium rich phosphorus and ______________
Correct Answer
cartilage
Explanation
When we are young, bones are made up of calcium-rich phosphorus and cartilage. Cartilage is a flexible connective tissue that provides support and cushioning to the growing bones. It acts as a precursor to bone formation and helps in the development and growth of the skeletal system. As we age, the cartilage gradually gets replaced by bone through a process called ossification. This transformation is essential for the formation of strong and rigid bones.Rate this question:
- 16.
Tough strips of tissue called _____________ connect bones together.
- A.
Tendons
- B.
Cartilage
- C.
Ligaments
- D.
Muscles
Correct Answer
C. LigamentsExplanation
Ligaments are tough strips of tissue that connect bones together. Unlike tendons, which connect muscles to bones, ligaments specifically connect bones to other bones. Ligaments play a crucial role in providing stability and support to joints, preventing excessive movement and potential injuries.Rate this question:
-
- 17.
_____________ keeps bones from rubbing together.
- A.
Tendons
- B.
Cartilage
- C.
Muscles
- D.
Tendons
Correct Answer
B. CartilageExplanation
Cartilage is the correct answer because it is a tough, flexible connective tissue that acts as a cushion between bones, preventing them from rubbing against each other. It provides support and reduces friction in joints, allowing for smooth and pain-free movement. Tendons, on the other hand, connect muscles to bones and play a role in movement, but they do not specifically prevent bones from rubbing together.Rate this question:
-
- 18.
______________allows muscles to attach to bones and help muscles move bones when muscles contact.
- A.
Cartilage
- B.
Tendons
- C.
Ligaments
Correct Answer
B. TendonsExplanation
Tendons allow muscles to attach to bones and help muscles move bones when muscles contract. Tendons are strong, flexible connective tissues that connect muscles to bones. When a muscle contracts, it pulls on the tendon, which in turn pulls on the bone, causing movement. Tendons are essential for the functioning of the musculoskeletal system as they transmit the force generated by the muscles to the bones, allowing for coordinated movement and stability.Rate this question:

A soft tissue called _______ makes white and red blood cells.
Correct Answer
marrowExplanation
Marrow is a soft tissue found inside bones that is responsible for the production of both white and red blood cells.Rate this question:
