Answer:
Its ampere.
Explanation:
The International System of Units defines the ampere in terms of other base units by measuring the electromagnetic force between electrical conductors carrying electric current.
Ok, a few things here:
This is an egg drop experiment, so I'm assuming you are testing out different ways of protecting the egg.
The independent variable is what you want to change: This would be the type of protection you have on the egg
The dependent variable is what would be effected by the changes in the independent variable: which would be something like the integrity of the egg after it hits the ground. You'd have to measure that somehow.
There are two types of controlled variables: <em>Internal and External.</em>
Internal variables are within the scope of the experiment and can be controlled, whereas external variables are outside the scope of the experiment and we have no control over them.
Internal:
- Height of the drop
- Type of egg
- Person dropping
- How the egg is dropped
- Surface being dropped on to
External:
- The person designated to drop the egg is sick
- You run out of eggs to drop
- Somebody loses all the planning for the experiment
- The weather forces you to do the experiment inside versus outside
- The wind blows your egg off course, leading to it hitting the ground at an angle
So, the way your teacher "chucks" the eggs off the roof should be a controlled internal variable. The action should be done as consistently as possible to avoid an uncontrolled variable.
The sense of hearing depends on which specialized cells?
Answer:
Receptors
The second choice.
Archaean biochemistry is more similar....etc.
Answer:
<em>The one of the worst infectious disease outbreaks in history was cholera.</em>
Explanation:
<em>The USA had three serious epidemies of cholera, which is an intestinal infection. It happened between 1832 and 1866, the pandemic began in India, and swiftly spread across the globe through trade routes. New York City was usually the first city to be infected. They estimated that two to six americans died per day during the outbreak. The end of cholera's outbreak is unclear, but researchers believe that it was related to quarantines or climate changes. The last cholera outbreak in USA was in 1911, the scientists found out that the effective treatment included antibiotics, zinc supplementation and rehydration.</em>
<em>Nowadays, 130.000 people dies every year all over the globe because of the disease. It has not been erradicated yet, but with modern sewage and water treatment, some countries are cholera free now. Unfortunately, some african countries and other underdeveloped countries still have the virus present there.</em>
<em>So the CDC recommends vaccines for those who intend to travel to high risk areas, and to wash hands regularly with soap and water, and only drinking mineral bottled water.</em>
