⏺Autotrophs--these are living things that use sunlight, chlorophyll,water and carbon dioxide to produce food.
⏺Circulatory System--it is best described as the lifeline of the body, the body's "pick up" and delivery system.
⏺arteries--carries the oxygen-rich blood to the head, arms, chest, and down to the waist and legs.
⏺neorons or nerve cells--are transmitters of messages from the different parts of the brain and vice versa.
⏺brainstem--part of brain controls the following activities: breathing,blood pressure,heart rate and alertness.
⏺Food chain--refers to a sequence of organisms in a community that constitutes a feeding chain.
⏺Ecological community--is a group of interacting plants,animals,and human in a particular area.
⏺Greenhouse effect--excessive presence if carbon dioxide in the air trapping heat near the earths surface causing a rise in temperature in the environment.
⏺moon's gravitational pull--causes high and low tides.
⏺Ozone layer--the Earth's shield against sun's harmful radiation.
⏺long shore drift--movement of sand and shingles along the coast.
⏺1950's--Theory of plate tectonics generally accepted.
⏺Erosion--the weathering away of rocks by water, wind and ice.
⏺calorie--the unit of measurement of energy in a given amount of food.
⏺amino acids--the building block of protiens.
⏺DNA--deoxyribonucleic acid.
⏺parthenogenesis--the development of egg without fertilization.
⏺Light--source of energy needed for photosynthesis.
⏺scientific theory--is a hypothesis not yet subjected to experimental test.
⏺mass--it is the measure of the amount of matter in an object.
⏺speed--is the distance traveled by the body by per unit time and tell how fast or slow the body moves.
⏺acceleration--the rate of change of the distance traveled per unit time in a stated direction.
⏺motion--is the reluctance of the object to change either it's state of rest or uniform motion in a straight line.
⏺Law of conservation energy--this law states that energy cannot be created nor destroyed but only changes form to another.
⏺kinetic theory--this law states that matter is made up of a large number of molecules which are continuous motion.
⏺ absolute zero--the lowest possible temperature that a substance can reach.
⏺specific heat capacity--is the amount of heat required to raise the temperature of kg. Of a substance by degree C.
⏺symbiotic relationship--the relationship of give-and-take of living organisms in a biosphere is a balanced of nature.
⏺aeration--process of removing excess odor in water.
⏺jupiter--is one of the planets has the greatest gravitational pull.
⏺law of enertia-- is the law which explains why one pull a piece without tapping a glass in a quick motion.
⏺work--application of energy.
⏺precipitation--the falling of any form of water from the air to the Earth's surface.
⏺ozone layer--the part of atmosphere that filters the ultraviolet rays of the sun.
⏺Perihelion--the point in the Earths orbit nearest to the sun.
⏺aphelion--the point in the Earths orbit farthest to the sun.
⏺phosphorescence--a property of minerals which gives off rays of light when exposed to ultraviolet light.
