What was early Autotroph called? Photoautotrophs What is an example of an Autotroph? Algae, along with plants and some bacteria and fungi, are autotrophs. Autotrophs are the producers in the food chain, meaning they create their own nutrients and energy. Kelp, like most autotrophs, creates energy through a process called photosynthesis. Why are humans referred […]
How do I make sure everyone has clean water?
How do I make sure everyone has clean water? 5 ways to improve water quality and access to water Improve sanitation facilities by providing toilets and latrines that flush into a sewer or safe enclosure. Promote good hygiene habits through education. Implement rainwater harvesting systems to collect and store rainwater for drinking or recharging underground […]
What is the use of Natrium 24?
What is the use of Natrium 24? Sodium 24 is used as an electrolyte tracer to follow the path sodium takes in a person’s body to see if their uptake levels are within normal ranges, while sodium 22 is used in nuclear medicine imaging for positron emission tomography. Sodium -24 can also be used in […]
How many red blood cells and white blood cells are in a single drop of blood?
Can two persons have same voice?
Can two persons have same voice? Although some people might sound quite a bit alike, no two voices are ever exactly alike. We each have a unique voice because so many factors work together to produce that voice. The pitch of your voice is largely determined by the length and tension of your vocal cords. […]
What is the difference between the bell and the diaphragm of a stethoscope?
What is the difference between the bell and the diaphragm of a stethoscope? The bell effect is created by light pressure on the stethoscope. Firm pressure makes the stethoscope behave like it should with a diaphragm. The difference between the diaphragm and the bell is that the bell allows low frequency sounds, which permits hearing […]
What happens to form an ionic bond quizlet?
What happens to form an ionic bond quizlet? An ionic bond is the force of attraction that holds together oppositely charged ions. It forms when atoms of a metal transfer electrons to atoms of a nonmetal. When this happens, the atoms become oppositely charged ions. As a result, ionic compounds are brittle solids with high […]
What is the difference between SAR and radar?
What is the difference between SAR and radar? SAR uses the motion of the radar antenna over a target region to provide finer spatial resolution than conventional beam-scanning radars. Additionally, SAR has the property of having larger apertures for more distant objects, allowing consistent spatial resolution over a range of viewing distances. What is the […]
Is current directly proportional to voltage?
Is current directly proportional to voltage? The relationship between current, voltage and resistance is expressed by Ohm’s Law. This states that the current flowing in a circuit is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit, provided the temperature remains constant. What is relation between voltage and current? […]
Who is known as the father of modern astronautics?
Who is known as the father of modern astronautics? For his ideas, careful research, and great vision, Tsiolkovsky has been called the Father of Modern Astronautics. Early in the 20th century, an American, Robert H. Goddard (1882-1945), conducted a variety of practical experiments in rocketry. When did Russia put a man in space? A Is […]
