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>
Hypothalamus. The hypothalamus is located at the base of the brain. It makes hormones that control hormones released in the pituitary gland. The hypothalamus controls water balance, sleep, temperature, appetite, mood and reproductive behaviors, and blood pressure.
Cerebellum controls balance for walking and standing, and other complex motor functions while the temporal lobe plays the role in processing affect/emotions, language and certain aspects of visual perception.
Answer:
Cell membrane present, ribosome present, lysosomes present, nuclear membrane present: Animals
Cell wall present, ribosomes present, nuclear membrane absent: Prokaryotic
Cell wall present, ribosome present, nucleus present, large vacuole present: Plants
Reproduces inside a cell, Nucleus absent, RNA present : Virus
Explanation:
Animals are multicellular organisms which do not possess cell wall. Hence option 1 represent animals.
Prokaryotes have cell wall but lack nuclear membrane. Hence, option 2 represents prokaryotes.
Plant cells have a cell wall, a nuclear membrane as well as a large nucleus. Hence option 3 is plants.
