Why does refrigerant absorb heat? The refrigerant leaves the expansion valve at low pressure and temperature then heads straight into the evaporator. The temperature of the room air is higher than the temperature of the cool refrigerant this allows it to absorb more energy and boil the refrigerant completely into a vapour. What carries the […]

What is the important of muscle and bone activity? Your bones and muscles work together to support every movement you make on a daily basis. When you are physically active you strengthen your muscles. Your bones adapt by building more cells and as a result both become stronger. Strong bones and muscles protect against injury […]

Can females ever be color blind? Color blindness isn’t common in females because there’s a low likelihood that a female will inherit both genes required for the condition. However, since only one gene is needed for red-green color blindness in males, it’s much more common. Does color blindness skip generations? it can often skip a […]

What is a first limiting amino acid? The first-limiting amino acid is the essential amino acid that first become deficient in the diet. Lysine is typically the first-limiting amino acid in most swine diets because the requirement of lysine is greater relative to the amount provided in the diet. What is a characteristic of a […]

Does a hypothesis turn into a theory? A hypothesis is not a prediction. A theory is not necessarily a well-supported explanation. A (causal) hypothesis does not become a theory if it subsequently becomes well-supported by evidence. How is a theory proven? A scientific theory is a description of the natural world that scientists have proven […]

Is the force of gravity the same on all objects? Gravity acts on all masses equally, even though the effects on both masses may be different because gravity causes all objects to fall at the same constant rate of 9.8 m/s2. An object in free fall means that the only force acting on the object […]

What are the 10 locomotor movements? The key locomotor skills are walking, running, jumping, hopping, crawling, marching, climbing, galloping, sliding, leaping, hopping, and skipping. What kind of movement is jumping? Jumping or leaping is a form of locomotion or movement in which an organism or non-living (e.g., robotic) mechanical system propels itself through the air […]
