Do antenna signal boosters work? TV aerial amplifiers and signal boosters do work. They can help overcome signal losses because of cable resistance and because of the splitting of signals to multiple TV’s. They won’t however miraculously convert a poor or weak TV signal, into a good reliable signal. But when used right they can […]
What are the disadvantages of parallel circuit?
What are the disadvantages of parallel circuit? The major disadvantage of parallel circuits as compared to series circuits is that the power remains at the same voltage as the voltage of a single power source. Other disadvantages include the split of an energy source across the entire circuit, and lower resistance. Why is parallel circuit […]
Is the sun a primary producer?
Is the sun a primary producer? This is how energy flows from one trophic level to the next. Living things need energy to grow, breathe, reproduce, and move. Energy cannot be created from nothing, so it must be transferred through the ecosystem. The primary source of energy for almost every ecosystem on Earth is the […]

Is aluminum foil a good insulator of cold?
What causes rubber bands to deteriorate?
What causes rubber bands to deteriorate? Most elastomers undergo rubber degradation over time and the most common rubber deterioration causes are exposure to light, oxygen (ozone) and heat. Oxidative and thermal ageing of rubber are accelerated by stress and reactive gases, like ozone, resulting in cracking, charring and colour fading. How long does rubber last? […]
Why is homeostasis important to the human body?
Why is homeostasis important to the human body? Homeostasis maintains optimal conditions for enzyme action throughout the body, as well as all cell functions. It is the maintenance of a constant internal environment despite changes in internal and external conditions. What 4 conditions in the body are related to maintaining homeostasis? Maintaining homeostasis The body […]

What must you do in fog or restricted visibility?
What must you do in fog or restricted visibility? All operators should navigate with extreme caution if visibility is restricted. Every vessel must proceed at a safe speed given the conditions of restricted visibility. A power-driven vessel must have its engines ready to manoeuvre immediately. What does a rapidly ringing bell every minute signal? According […]
