• The general functions of the Skeletal system include giving shape to the body, serving as a framework of the body, protecting the internal organs of the body, and converting energy, which enables the body to move.
• Justine's muscles, which include the arm muscle, leg muscle, facial muscle, and heart muscle, help her reach the prize during the game.
• The muscular system allows us to move, supports and makes our skeleton in the hands and other body parts steady, provides the structural framework for the body, and gives shape to the body.
• Gina's stomach takes 3-7 hours to be emptied, hence the best time for her to take her lunch is at 11:30 o'clock in the morning.
• Digestion occurs through the mouth, esophagus, stomach, small intestine, large intestine, rectum, and anus.
• It is important to promote healthful habits for our organs to function properly, avoid death, and keep our body away from diseases.
• Dynamite fishing, if continued, will lead to a decrease in marine life.
• Mangrove swamps are important components of the ecosystem and are usually found along tropical and subtropical coastlines.
• Coral reefs are important to marine life as they are the habitat of some marine animals, they make the oceans and seas look blue, they filter and purify the water, and they make the seawater salty.
• A tropical rainforest ecosystem is located in tropical places, caters to few plants and animals, and has diverse plant and animal species.
• The greatest variety of organisms and the longest period of time for their survival are supported by a wide variety of organisms, animals, bacteria, minerals, and other elements.
• Coral reefs are important to man and other marine organisms and can be protected by collecting corals, cleaning coral reefs, preventing dynamite fishing, and throwing oil into waterways.
• Crustaceans like crabs play a role in the mangrove ecosystem by attaching themselves to the roots of mangroves, helping break down leaf litter through grazing, serving as food of other animals, and finding food in the mud.
• The correct path that a nerve impulse will follow in a reflex arc is: Motor neuron—sensory neuron—interneuron.
• Some worms are harmful because they grow very long.
• Bat, dolphin, whale, penguin are examples of animals grouped as mammals.
• The respiratory system is linked to the circulatory system because the oxygenated blood passes through the arteries.
• The skin regulates the body temperature by increasing sweat production.
• The skin is one of the first defense mechanisms in the immune system because it secretes oils that increase the function of the skin to protect against microorganisms.
• Sensory neurons carry signals from the central nervous system to the outer parts of the body.
• When a person gets cold or frightened, the skin contracts.
• The integumentary system works with the nervous system by protecting the nerves.
• Reptiles have distinct characteristics such as legs for crawling, being warm blooded animals, having gills and fins, and dry scaly skins.
• The blood from the lungs travels back into the heart through the pulmonary veins, left atrium, and left ventricle.
• Four animals identified as vertebrates are sheep, dog, lion, and tiger.
• Cnidarians get their food through food and water flowing through a small opening.
• Birds are vertebrates that lay eggs with shells and take care of their young.
• Mammals have four legs, creep and live on land, feed their young with milk, and have scales and live on water.
• Animals acquire food in different ways.
• Sponges and cnidarians are sessile or stationary.
• Conifers use seeds to reproduce.
• Ferns and mosses are alike in that they have vascular bundles and roots, stems and leaves.
• Plants undergo a process of reproduction.
• Mollusks have soft bodies and may be covered with hard shells.
• Fishes are animals that can move easily in the water.
• Ferns and mosses are non-flowering plants that produce spores.
• Cnidarians capture prey with stinging cells on their tentacles.
• Pine, mahogany, fern, and moss are cone-bearing plants.
• Mollusks live in bodies of other animals.
• Sponges absorb food through suckers.
