PKU PKU is a genetic disorder that affects the ability to break down a certain amino acid.
transgenic organism Transgenic organism has genes from another species.
Artificial insemination Artificial insemination places sperm directly into the uterus.
In vitro fertilization In vitro fertilization (IVF) combines egg and sperm in a lab.
Vegetative propagation Vegetative propagation is asexual plant reproduction using parts like stems or roots.
Therapeutic cloning Therapeutic cloning creates stem cells to treat diseases.
Gene cloning Gene cloning copies a specific gene for research or therapy.
Reproductive cloning Reproductive cloning makes a genetic copy of an entire organism.
Reproductive technology Reproductive technology helps people have children using science.
MRI MRI uses magnets and radio waves to image soft tissues.
CAT scan CAT scan (CT) gives a detailed 3D view of body structures.
X-rays X-rays show bones using radiation.
Ultrasound Ultrasound uses sound waves to view soft tissues like babies in the womb.
Scanning technology Scanning technology lets doctors see inside the body.
negative feedback Negative Feedback maintains homeostasis and brings systems back to a set point (stabilizing).
positive feedback Positive Feedback amplifies a change or process, driving it toward completion (enhancing).
Temperature levels Temperature levels are controlled by sweating, shivering, and blood flow.
Water levels Water levels are controlled by kidneys and hormones.
Sugar levels Sugar levels are controlled by insulin and glucagon.
Oxygen levels Oxygen levels are controlled by breathing and circulation.
Homeostasis Homeostasis keeps the body’s internal conditions stable.
Digestive system Digestive system breaks down food and absorbs nutrients.
Excretory system Excretory system removes waste from the body.
Circulatory system Circulatory system moves blood, oxygen, and nutrients around the body.
Integumentary system Integumentary system includes skin, hair, and nails for protection.
Respiratory system Respiratory system allows breathing and gas exchange.
Organ systems Organ systems are groups of organs that perform body functions.
Difference between veins and arteries is veins Difference between veins and arteries is veins have valves and carry blood to the heart, arteries carry blood away.
Inferior and superior vena cava Inferior and superior vena cava bring deoxygenated blood back to the heart.
Heart pumps blood Heart pumps blood throughout the body.
Lungs exchange what Lungs exchange gases through small air sacs called alveoli.
Respiratory system brings in Respiratory system brings in oxygen and removes carbon dioxide.
Parts of the skin include what Parts of the skin include epidermis, dermis, and subcutaneous layer.
nimal organs include the Animal organs include the heart, lungs, brain, and skin.
Plant tissues include Plant tissues include xylem (water), phloem (sugar), and epidermis (protection).
Plants perform Plants perform photosynthesis and have roots, stems, and leaves.
Connective Connective tissue supports, connects, and holds parts together.
Muscle Muscle tissue contracts to allow movement.
Nerve Nerve tissue sends and receives electrical signals.
Epithelial tissue Epithelial tissue covers and protects surfaces.
Animal tissue includes four types epithelial, nerve, muscle, and connective.
Unipotent stem cells can Unipotent stem cells can become only one specific type of cell.
Pluripotent stem cells Pluripotent stem cells can become any body cell except placenta.
Totipotent stem cells can Totipotent stem cells can become any cell including placenta.
Regeneration is when Regeneration is when organisms regrow lost body parts.
Stem cells can Stem cells can become different types of body cells.
