Why do we need replicates in an experiment? The replication reduces variability in experimental results. Stop of variability increases their significance and the confidence level. Finally, the researcher can draw conclusions about an experimental. Scientists must replicate experiments to ensure validity and account for error. Why is repetition of experiment important? The repetition principle is […]
Why is the sodium potassium pump so important to the human body?
Why is the sodium potassium pump so important to the human body? In the kidneys the Na-K pump helps to maintain sodium and potassium balance in our body. It also plays a key role in maintaining blood pressure and controls cardiac contractions. What human body system depends on the sodium potassium pump? nervous system Why […]
How gravity is created?
How gravity is created? Earth’s gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body. You exert the same gravitational force on Earth that it does on you. But because Earth is so much more massive than you, your force doesn’t really have an […]
Whats does screw mean?
Whats does screw mean? The Oxford English Dictionary defines screw as “to tighten; to press or force by means of a screw; or to extort by pressure.” The most common image or gesture that one thinks of when first hearing this word usually deals with the repeated motion that one uses to tighten a screw […]
What particle size is the easiest to erode?
What particle size is the easiest to erode? In a stream, the most easily eroded particles are small sand grains between 0.2 mm and 0.5 mm. Anything smaller or larger requires a higher water velocity to be eroded and entrained in the flow. What increases the size of particles carried increases? The average velocity (speed) […]
Why must I forgive?
Why must I forgive? Forgiveness is for our own growth and happiness. When we hold on to hurt, pain, resentment, and anger it harms us far more than it harms the offender. Forgiveness frees us to live in the present. Our anger, regret, hatred, or resentment towards someone means that we are giving up our […]

Scholarly, peer-reviewed articles or books -written by researchers for students and researchers. Original research, extensive bibliography. Why is it important to evaluate sources? Evaluating information encourages you to think critically […]
How do you classify archaea?
How do you classify archaea? Archaea, (domain Archaea), any of a group of single-celled prokaryotic organisms (that is, organisms whose cells lack a defined nucleus) that have distinct molecular characteristics separating them from bacteria (the other, more prominent group of prokaryotes) as well as from eukaryotes (organisms, including plants and … What two groups does […]
What is the effective resistance between A and D?
What is the effective resistance between A and D? D=5Ω+10Ω+5Ω=20Ω What is the effective resistance in the given circuit? The effective resistance of a circuit containing resistances in parallel is smaller than any of the individual resistances. For example : R1=2Ω and R2=3Ω ∴ Effective resistance Rp1=R11+R21. Maximum effective resistance will be when all the […]
What caused the 5 mass extinctions?
What caused the 5 mass extinctions? The most commonly suggested causes of mass extinctions are listed below. Flood basalt events. The formation of large igneous provinces by flood basalt events could have: Sea-level falls. Impact events. Global cooling. Global warming. Clathrate gun hypothesis. Anoxic events. Hydrogen sulfide emissions from the seas. Can global warming cause […]
