Answer and Explanation:
- What was Patrick’s hypothesis? <em>Fishes that are fed with food exposed to the microwave will become smarter and will swim faster. </em>
- Which fish are in the control group? The ones that feed on regular food
- What is the independent variable? Food exposed to the microwave
- What is the dependent variable? The time fishes spend in swimming through the maze
- What should Patrick’s conclusion be? You will find the results considered in the attached file.
<em>In both groups, Patrick recorded a decrease in the time spent swimming through the maze</em>. In both groups, there were two cases in which the animal increase the swimming time. These cases could be considered as outliers. Although in general, <em>the treated group made it in a shorter time after the treatment, when comparing values before and after Patrick can not find any real difference among groups.</em> <em>His results do not show any difference,</em> hence <em>the speed and the intelligence of the animals is not influenced by the change in food, or if it is, more experimental time is required to record significant differences. </em>
Definition:
Weathering is the breakdown of rocks at the Earth’s surface, by the action of rainwater, extremes of temperature, and biological activity. It does not involve the removal of rock material.
There are 3 types of weathering:
a)physical
b)chemical
c)biological
•Physical weathering is caused by the effects of changing temperature on rocks, causing the rock to break apart. The process is sometimes assisted by water.
•Chemical weathering is caused by rain water reacting with the mineral grains in rocks to form new minerals (clays) and soluble salts. These reactions occur particularly when the water is slightly acidic.
•Biological weathering is the weakening and subsequent disintegration of rock by plants, animals and microbes. Growing plant roots can exert stress or pressure on rock.

Earthquakes occur all the time all over the world, both along plate edges and along faults. Most earthquakes occur along the edge of the oceanic and continental plates. The earth's crust (the outer layer of the planet) is made up of several pieces, called plates. The "Ring of Fire", also called the Circum-Pacific belt, is the zone of earthquakes surrounding the Pacific Ocean- about 90% of the world's earthquakes occur there.
