Examples of hormones include insulin, thyroxine, adrenaline, growth hormone, estrogen, progesterone, cortisol, and glucagon. Hormones are chemical messengers. They are produced by glands and released into the blood. The blood carries them to the target organs. A target cell is a cell that has a matching receptor for a hormone. … Continue Reading
Examples of neurotransmitters include Acetylcholine, dopamine, serotonin, GABA, glutamate, histamine, oxytocin, glycine, and endorphins. Neurotransmitters are chemical messengers in the nervous system. These chemicals control communication between brain cells and body functions. These are the signaling molecules secreted by a neuron to excite or inhibit the other neuron across synapse. … Continue Reading
Examples of biofuels include bioethanol, biodiesel, biogas, biojet fuel, wood waste, cellulosic ethanol, biomethanol, charcoal, and agricultural residue fuels. Biofuels are a type of energy. They come from biological materials. These materials are called biomass. Biomass includes plants as well as animal waste. Biofuels are different from fossil fuels such … Continue Reading
Examples of plants having rhizomes include ginger, turmeric, lotus, bamboo, iris, galangal, wasabi, snake plant, asparagus, rhubarb, alstroemeria, many ferns, Bermuda grass, poison oak, and Chinese lantern.A rhizome is an underground stem that grows sideways. A rhizome is not a root. It has nodes and internodes just like stems that … Continue Reading
Examples of Endocrine Disruptors include bisphenol A, phthalates, dioxins, PCBs, endosulfan, atrazine, lead, mercury, estrogenic drugs, and triclosan. Endocrine disruptors are chemicals that interfere with hormones in the body.Hormones control growth, development, metabolism, and reproduction. Endocrine disruptors can mimic, block, or change natural hormones, causing health problems in humans and … Continue Reading
Taproot is the main, central large root that grows vertically downward from the plant. It develops from the radicle of the seed during germination. The taproot gives rise to smaller lateral roots, called secondary and tertiary roots. Taproot is straight, thick, and usually tapers at the bottom. Taproot systems are … Continue Reading
Examples of nanomaterials include carbon nanotubes, graphene, nanoparticles, quantum dots, nanoclay, fullerenes, and nano-coatings. Nanomaterials are very tiny materials. These materials have at least one size between 1 and 100 nanometers. A nanometer is extremely small. It is one billionth of a meter. These can be stronger, lighter, and more … Continue Reading
Some common examples of innate immunity include skin, mucous membranes, cilia, tears, saliva, stomach acid, urine, skin oils, earwax, cough reflex, sneezing, neutrophils, macrophages, natural killer cells, dendritic cells, basophils, eosinophils, interferons, fever, inflammation, and normal microbiota. What is Innate Immunity? Innate immunity is the body’s first line of defense … Continue Reading
Turbidity means how cloudy or unclear the water is. Water becomes turbid when small particles float in it. These small particles are called suspended solids. These particles can be dirt, sand, algae, or even pollution. Because of these tiny particles, the water appears cloudy or muddy. Causes of turbidity in … Continue Reading
Common examples of analogous organs include wings of birds, butterflies, and bats; flippers of dolphins, penguins, and sharks; eyes of octopus and humans; storage organs like sweet potato and potato; climbing structures like pea and grapevine tendrils; protective spines of firethorn and barberry; and photosynthetic stems of opuntia. What are … Continue Reading
