Are radioisotopes used in MRI scans? When used in medical practices, radioisotopes are used particularly for diagnosis and therapy of various medical conditions. In regards to diagnoses, the isotopes are used in conjunction with scanning machines such as MRI, CT scans, and others, to image and diagnose disorders that couldn’t otherwise be seen. What are […]
What is the formula for NH4 and O?
What are the problems with space exploration?
What are the problems with space exploration? Problem: Space travel can present extreme environments that affect machine operations and survival. Like humans, machines are impacted by gravity, propulsive forces, radiation, gases, toxins, chemically caustic environments, static discharge, dust, extreme temperatures, frequent temperature variations and more. How does space exploration affect the economy? “In this new […]
What is Fertilisation inside the body of a female called?
What is Fertilisation inside the body of a female called? Fertilization which takes place inside the female body is called internal fertilization in animals is done through the following different ways: Via spermatophore, a sperm-containing cap placed by the male in the female’s cloaca. What Animals use external fertilization? Many fish, amphibians, and other sexual […]
Why do we need replicates in an experiment?
Why do we need replicates in an experiment? The replication reduces variability in experimental results. Stop of variability increases their significance and the confidence level. Finally, the researcher can draw conclusions about an experimental. Scientists must replicate experiments to ensure validity and account for error. Why is repetition of experiment important? The repetition principle is […]
Why did I gain 5 lbs overnight?
Why did I gain 5 lbs overnight? What Makes You Gain Weight Overnight? Many different things, such as water retention due to sodium, hormones, meal timing, and stress can make you gain weight overnight. The reason people gain weight after a night of eating out is most likely due to increased sodium and carbohydrate intake. […]
What is the relationship between intensity?
What is the relationship between intensity? indicates the average value of the quantity q.) to describe the medium of propagation. What is the same for all types of waves, the main point here, is that the intensity is proportional to the square of the amplitude. Does voltage increase with light intensity? For the short-circuit current, […]
How gravity is created?
How gravity is created? Earth’s gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body. You exert the same gravitational force on Earth that it does on you. But because Earth is so much more massive than you, your force doesn’t really have an […]
Do microwaves have radiation?
Do microwaves have radiation? Microwaves are a form of “electromagnetic” radiation; that is, they are waves of electrical and magnetic energy moving together through space. Electromagnetic radiation spans a broad spectrum from very long radio waves to very short gamma rays. But the most common consumer use of microwave energy is in microwave ovens. What […]
What caused the 5 mass extinctions?
What caused the 5 mass extinctions? The most commonly suggested causes of mass extinctions are listed below. Flood basalt events. The formation of large igneous provinces by flood basalt events could have: Sea-level falls. Impact events. Global cooling. Global warming. Clathrate gun hypothesis. Anoxic events. Hydrogen sulfide emissions from the seas. Can global warming cause […]
