What is adaptation example? Adaptation is the evolutionary process where an organism becomes better suited to its habitat. An example is the adaptation of horses’ teeth to grinding grass. Grass is their usual food; it wears the teeth down, but horses’ teeth continue to grow during life. Is sweating a human adaptation? The only mechanism […]
How do you find the largest radius?
How do you find the largest radius? Atomic radii vary in a predictable way across the periodic table. As can be seen in the figures below, the atomic radius increases from top to bottom in a group, and decreases from left to right across a period. Thus, helium is the smallest element, and francium is […]
Why is volume measured in cm3?
Why is volume measured in cm3? Volume is commonly measured in cubic units, such as cm3, because volume is a measure of an object’s length, width and height as shown below. A) Calculate the volume of the box. How much space does the box take up? Is capacity and volume the same? Volume and capacity […]
What is the circumference of a right circular cylinder?
How does the blood circulate in the body?
How does the blood circulate in the body? Blood comes into the right atrium from the body, moves into the right ventricle and is pushed into the pulmonary arteries in the lungs. After picking up oxygen, the blood travels back to the heart through the pulmonary veins into the left atrium, to the left ventricle […]

What is the difference between philosophy and scientific method?
What is the difference between philosophy and scientific method? The main difference is in the way they work and treat knowledge. 2. Science is concerned with natural phenomena, while philosophy attempts to understand the nature of man, existence, and the relationship that exists between the two concepts. Science also takes answers and proves them as […]
How does a roller coaster work without an engine?
How does a roller coaster work without an engine? As the roller coaster falls, it accelerates and builds up enough kinetic energy to propel it through the remainder of the ride. No engine is required because of inertia. As you ride a roller coaster, its wheels rub along the rails, creating heat as a result […]
What is the 3 second rule in lacrosse?
What is the 3 second rule in lacrosse? As you might imagine, the three-second rule gives offensive players three seconds to do one of two things: pass the ball or change her cradle, which is the manner in which she’s holding the ball. If the offensive player isn’t able to adhere to this rule, the […]
Why does a moving charge create magnetic field?
Why does a moving charge create magnetic field? A charged particle moving without acceleration produces an electric as well as a magnetic field. It produces an electric field because it’s a charge particle. All of a sudden when it starts moving, it starts producing a magnetic field. Why is B used for magnetic field? Originally […]
