If you are talking about Photosynthesis or Cellular Respiration, or any other chemical reactions, this answer is most suitable for the context.
The answer to this question would be “2) Requires enzymes”, since chemical reactions can only be carried out and completed through catalysts, which increase the rate of a chemical reaction and an enzyme is a specific example of a catalyst, so I think that it would be the best answer.
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:
At a cellular level, smooth muscle functions as an involuntary non-striated muscle. Smooth muscle contains thick and thin filaments that do not arrange into sarcomeres, resulting in a non-striated pattern.
Explanation:
Answer:
the male part of a flower is called the stamen, it consists of a long slender stalk, the filament, with a two-lobed anther at the tip.
the female part of a flower is called the pistil, it consists of the stigma, the style, the overy and the ovule.
