Why is cloning wrong? Human beings should not be cloned for several reasons that are going to be further discussed in this op-ed: cloning is a risky, imperfect procedure, it does not create an exact copy of an individual, and it poses ethical concerns by using human beings as a means to an end, opening […]
What is a controlled variable in science?
What is a controlled variable in science? A control variable is anything that is held constant or limited in a research study. It’s a variable that is not of interest to the study’s aims, but is controlled because it could influence the outcomes. What does control mean in science examples? A scientific control is an […]
What happens if you fly too soon after diving?
What happens if you fly too soon after diving? The concerns of heading to altitude too soon after diving are the same as those when you ascend from your dive too quickly because the same scientific principles apply: going to altitude takes you to an area of lower outside pressure, meaning residual nitrogen still dissolved […]
What is the best angle for a propeller?
What is the best angle for a propeller? around 2 to 4 degrees What is the greatest force on a propeller? Centrifugal force is a physical force that tends to throw the rotating propeller blades away from the hub. This is the most dominant force on the propeller. Torque bending force, in the form of […]
What is Coriolis effect and how does it affect weather?
What is Coriolis effect and how does it affect weather? Outside storm systems, the impact of the Coriolis effect helps define regular wind patterns around the globe. As warm air rises near the Equator, for instance, it flows toward the poles. In the Northern Hemisphere, these warm air currents are deflected to the right (east) […]
Which is more elastic veins or arteries?
Which is more elastic veins or arteries? In arteries, the tunica media, which contains smooth muscle cells and elastic tissue, is thicker than that of veins so it can modulate vessel caliber and thus control and maintain blood pressure. Larger arteries are typically elastic and smaller arteries are more likely to be muscular. What are […]
What is the purpose of synaptic gap?
What is the purpose of synaptic gap? A synaptic cleft is a space that separates two neurons. It forms a junction between two or more neurons and helps nerve impulse pass from one neuron to the other. What occurs in synaptic gap? At a synapse, one neuron sends a message to a target neuron—another cell. […]
What is the difference between the time constant in RC circuit and RL circuit?
What is the best example of producer?
What is the best example of producer? One example of producers found in food chains include plants. They use photosynthesis to make their own food. Examples of plants include trees, grass, moss, flowers, and weeds, to name a few. What’s an example of producer? Diatom Is a cow a secondary consumer? In an ecosystem’s food […]
What do both primary and secondary succession begin with?
What do both primary and secondary succession begin with? The stages of secondary succession are similar to those of primary succession; however, primary succession always begins on a barren surface, whereas secondary succession begins in environments that already possess soil. What are some causes of secondary succession? Examples of disturbances that cause secondary succession include […]
