How do global winds influence local weather? The way the air moves affects the weather, because winds move heat and cold temperatures as well as moisture from one place to another, transporting conditions from one geographical zone to another. The way winds pass each other, and the direction they move, also affects what weather a […]
What is the best example of muscular strength?
What is the best example of muscular strength? Examples of muscle-strengthening activities include: lifting weights. working with resistance bands. heavy gardening, such as digging and shovelling. climbing stairs. hill walking. cycling. dance. push-ups, sit-ups and squats. Can muscle wasting be reversed? Your inability to move may be be due to an injury or an underlying […]
What do we call a covalent bond where electrons are shared unequally?
What do we call a covalent bond where electrons are shared unequally? A polar covalent bond is a covalent bond in which the atoms have an unequal attraction for electrons and so the sharing is unequal. In a polar covalent bond, sometimes simply called a polar bond, the distribution of electrons around the molecule is […]
Can Venus support human life?
Can Venus support human life? To date, no definitive proof has been found of past or present life on Venus. With extreme surface temperatures reaching nearly 735 K (462 °C; 863 °F) and an atmospheric pressure 90 times that of Earth, the conditions on Venus make water-based life as we know it unlikely on the […]
What two adaptations do animals have to avoid being captured?
What two adaptations do animals have to avoid being captured? Adaptations and Behavior Question mimicry and camouflage. hibernation and mimicry. camouflage and hibernation. What are two predator adaptations? Many predatory animals, both vertebrate and invertebrate, have sharp claws or jaws to grip, kill, and cut up their prey. Other adaptations include stealth and aggressive mimicry […]

What are the similarities between distillation and evaporation?
What are the similarities between distillation and evaporation? The similarity between evaporation, drying and distillation is that they all involve matter going from a liquid phase to a gas phase. In evaporation, this process can occurs at ambiant temperature (below the boiling temperature of the liquid). What is advantage of distillation over evaporation? This is […]
What is the pH color scale?
What is the pH color scale? Universal indicator and the pH scale This is measured using the pH scale , which runs from pH 0 to pH 14. Universal indicator has many different colour changes, from red for strongly acidic solutions to dark purple for strongly alkaline solutions. In the middle, neutral pH 7 is […]
Why does the kinetic energy of a charged particle moving in a magnetic field remains constant?
Why does the kinetic energy of a charged particle moving in a magnetic field remains constant? When a charged particle moves in a magnetic field, does its kinetic energy always remain constant? This means that a uniform magnetic field can do no work on charged particle although it can change its direction of motion. Hence […]
Can you see fat in an MRI?
Can you see fat in an MRI? Magnetic Resonance Imaging (MRI) As with CT, MRI imaging protocols provide not only detailed images of fat depots but can also characterize disease processes in other organs that may be associated with different types of obesity. What happens to T2 as the strength of the main magnetic field […]
