Characteristics of Life
What the smallest unit of life?
Cell
What type of joint allows for movement in only one plane?
Hinge Joint
What is the largest artery in the body?
Aorta
This part of the circulatory system pumps blood throughout the body.
Heart
In Kwajalein, local athletes and people participating in sports like volleyball or soccer need flexible joints. What type of joint is found in the elbow, allowing it to extend and flex?
hinge joint
One example of a Characteristic of Life
CELLULAR ORGANIZATION, HOMEOSTASIS, ADAPTATION & EVOLUTION, REPRODUCTION, GROWTH & DEVELOPMENT, ENERGY (METABOLISM), RESPONSE TO STIMULI
What type of joint allows movement in two planes, but not in a full rotation?
Condyloid Joint
What is the primary function of arteries?
Blood vessels that carry oxygenated blood away from the heart to organs.
This major sporting event, held every four years, often highlights the wear and tear on joints, with athletes suffering from knee and shoulder injuries, particularly in high-impact sports.
Summer or Winter Olympics
The local tradition of weaving baskets in the Marshall Islands requires precise hand movements. What type of joint in the thumb allows for gripping and manipulating objects?
Saddle Joint
Define homeostasis
The ability of organisms to maintain a specific internal environment.
What joint is found between the carpal bones and allows sliding movements?
Gliding (Plane) Joint
How do veins differ from arteries in terms of structure and function?
Carry deoxygenated blood into the heart with valves
Tinner & Stretchy Walls-With low pressure contracts slightly to help push blood back to the heart.
In 2020, a group of researchers discovered how some species of bacteria could survive in extreme conditions. What characteristic of life does this show?
Adaptation
During the dry season on Kwajalein, many plants use less water to survive, showing their ability to maintain balance with limited resources.
homeostasis
Give an example of how organisms respond to stimuli.
Animals: Touching a Hot Surface (Reflex Response), Pupillary Response to Light , Predator Avoidance (Fight or Flight), Salivating at the Smell of Food, Hibernation in Cold Weather, Sweating to Cool Down, Shivering to Generate Heat
Plants - Phototropism (Response to Light), Gravitropism (Response to Gravity), Thigmotropism (Response to Touch), Closing of Leaves (Mimosa Plant), Flowering Based on Day Length
What joint allows the widest range of motion?
Ball and Socket Joint
What is the role of capillaries in the circulatory system?
Exchanges oxygen and nutrients to cells and carbon dioxide moves from cells into capillaries to be transported to the lungs for removal.
In 2020, this condition, often associated with high blood pressure, became a major focus of health campaigns aimed at preventing strokes and heart disease.
hypertension (high blood pressure)
When someone on Kwajalein exercises outdoors in the warm climate, their heart rate increases. This causes blood to flow more rapidly through these large blood vessels.
arteries
What is scientific term for how organisms obtain energy from food?
Cellular Metabolism
What is the purpose of the immovable joints in the skull?
Protect the Brain, Provide Structural Support, Allow for Growth in Infants
What major vein carries blood from the lower body to the heart?
Inferior Vena Cava
This condition, affecting the cartilage in joints, often leads to pain and swelling, and it worsens with age.
osteoarthritis
On Kwajalein, the tropical heat can cause people to sweat, which helps cool the body by regulating blood flow to the skin. What blood vessels are involved in this process?
capillaries
