General Science Flashcards
Living organisms that use sunlight, chlorophyll, water, and carbon dioxide to produce food
Autotrophs
Describe as the lifeline of the body. It is the body’s pick-up and delivery system.
Circulatory System
It carries the oxygen-rich blood to the head, arms, chest and down to the waist and legs.
Arteries
They are the transmitters of message from the different parts of the body to the brain and vice versa.
neurons
The part of the brain controls breathing, blood pressure, heart rate, alertness (involuntary)
brainstem
a sequence of organism in a community that constitutes a feeding chain
food chain
Agroup of interacting plants, animals, and human in a particular area
ecological community
excessive presence of carbon dioxide in air, trapping heat near the Earth’s surface causing a rise in temperature in the environment
Greenhouse Effect
The Earth’s shield against sun’s harmful radiation
Ozone layer
contributes to the depletion of the ozone layer
chlorofluorocarbon
causes high and low tides
Moon’s gravitational pull
Parallel to the moon (tide)
high tide
Perpendicular to the moon (tide)
Low tide
Corals growing around a volcanic island
coral atoll
movement of sand and shingles (pebbles) along the coast
long shore drift
cold front pushing warm air up the ground
occlusion
A distorted image resulting from the bending of sun’s light rays by changes in air temperature
heat haze
himalayas mountain ranges’ rock formation
fold eruptions
a force that wears down mountains
erosion
collision of two oceanic plates
volcanic island
the theory of plate tectonics by Alfred Wegener generally accepted
1950
The weathering away (transfer) of rocks by water, wind, and ice
erosion
controls cell chemistry (alter chemical composition)
hormones
male and female sex hormones
sperm cell and ovum
