You may want to let them know about there X-ray but after you should assure them that there is a solution and you'll both get to it
Answer:
Taxonomy allows a better understanding of relationships among species.
Explanation:
Aim/objective: To determine the effect of carbon dioxide concentration on the rate of photosynthesis.Problem statement :What is the effect of carbon dioxide concentration on the rate of photosynthesis? Hypothesis When the concentration of carbon dioxide increases, the rate of <span>photosynthesis also increases until the rate becomes constant.</span>VariablesManipulated : Concentration of carbon dioxideResponding : The rate of photosynthesis// The number ofbubble releasedper minute<span>Constant : Light intensity, temperature/ Size of plant</span> Apparatus and materials:Materials :Elodea/Hydrilla ,different concentration of sodium bicarbonate,distilled water Apparatus : Beaker, boiling tube, clip, table lamp, filter funnel Technique :Count and record the number of bubbles produced / released in 20 minutesusing a stopwatch.Procedure:1<span>.Diagram of experimental setup with at least 5 functional labels.</span><span>2.Fill a boiling tube with</span>150 ml of 1%sodium hydrogen carbonate solution. <span>3.Fix a paper clip / plasticine to a sprig of aquatic /</span>Hydrillasp. plant.4.Submerge / put the aquatic plant into the boiling tube containing1% sodium hydrogen carbonate solution.5.Put the boiling tube into a water bath at room temperature (20-30oC). 6.Place the boiling tube at distance of 50 cm from a lighted bulb. 7.Put aside the boiling tube for 5 minute (for the aquatic plant to adjust).8.Start the stopwatch.9.Count the number of bubbles release in 20 minutes.10.Record the result is a table.11.Repeat steps 2 until10 using 2%, 3%and 4%of sodiumhydrogencarbonate solutions. 12.Calculate the rate of photosynthesis.(Rate of photosynthesis = Number of bubbles/time)13.Precaution : Count the bubbles only after the rate becomesconstant. DataInclude the following titles with units:-Concentration of sodium hydrogen carbonates solution (%)-Number of bubbles released in 20 minutes -Rate of photosynthesis (number / minute) Conclusion:When the concentration of carbon dioxide increases, the rate of <span>photosynthesis also increases until the rate becomes constant. Hypothesis</span><span>is accepted.</span>
Answer:
B. It relies on personal experience
Explanation:
In pseudoscience, no official experimentation is required.
