The plant would weigh 5 kg more due to the process of photosynthesis, where it converts carbon dioxide and water into glucose and oxygen. The carbon in the glucose comes from the carbon dioxide in the air, while the hydrogen comes from the water in the soil. The almost 5 kg less weight would be attributed to the oxygen released during photosynthesis, which is a byproduct of the process.
What else can I help you with?
Francesco Redi conducted an experiment to test the hypothesis that maggots arose spontaneous generation. what prediction did he make in designing his experiment?
The prediction that he made in designing his experiment was called the scientific method.
How did Pasteur's experiment differ from spallanzani experiment?
Pasteur's experiment on spontaneous generation showed that microorganisms do not arise spontaneously but are introduced into broths from external sources. Spallanzani's experiment involved boiling nutrient broth in sealed flasks to sterilize it, then observing that no microorganisms grew unless air was allowed to enter the flask, suggesting that microbes were not generated spontaneously but entered from the air.
What Happened In Experimental Group In Spallanzani's Experiment?
In Spallanzani's experiment, the experimental group received boiled broth that was then sealed from external contamination. This group did not exhibit the growth of microorganisms, providing evidence against spontaneous generation.
What experiment did Pasteur conduct to demonstrate that there was no spontaneous generation of life?
Louis Pasteur conducted the swan-neck flask experiment to demonstrate that there was no spontaneous generation of life. He showed that when broth was heated and sealed in a flask with a curved neck, no microorganisms grew, proving that life did not spontaneously arise from non-living matter.
What if growth appears on one of the unopened plates?
If growth appears on one of the unopened plates, it could indicate that there was contamination before the plate was sealed or that the plate was not properly sterilized. This may compromise the validity of the experiment, and you may need to repeat it with proper precautions to ensure accurate results.
How was Noah's covenant sealed?
God placed a rainbow in the sky
How are products packed?
In boxes, rolled in paper, sealed in cellophane or placed in bags.
What is a capillary melting point?
The sample is placed in a sealed capillary and heated up to the melting.
How are bakery products packed?
In boxes, rolled in paper, sealed in cellophane or placed in bags.
What did fransesco redi show in his experiment?
Francesco Redi conducted a famous experiment in the 17th century to demonstrate that maggots on decaying meat came from eggs laid by flies, not from spontaneous generation. He placed meat in three jars: one open to the air, one sealed, and one covered with gauze. The open jar attracted flies, which laid eggs and resulted in maggots, while the sealed jar remained free of maggots, and the gauze-covered jar allowed air in but prevented flies from accessing the meat. Redi's experiment helped establish the principle of biogenesis, the idea that life arises from existing life.
How candle is lighted from inside of the bell jar experiment made by Priestley?
In Priestley's bell jar experiment, a lit candle is placed inside a bell jar, which is then sealed. As the candle burns, it consumes oxygen and produces carbon dioxide, leading to a decrease in oxygen levels within the jar. Eventually, the flame extinguishes due to insufficient oxygen for combustion. This experiment demonstrated the importance of oxygen for burning and laid the groundwork for understanding gases in respiration.
Why is it important that the flask be sealed for this experiment even after the flask is returned to an upright position?
Keeping the flask sealed after it is returned to an upright position prevents any air or gas from escaping, ensuring that the pressure inside the flask remains constant. This helps to maintain the accuracy of the experiment's results by keeping the conditions consistent.
Who in the 1800's performed an experiment using broth in a sealed and unsealed flask to prove spontaneous generation wrong?
Pasteur
Francesco Redi conducted an experiment to test the hypothesis that maggots arose spontaneous generation. what prediction did he make in designing his experiment?
The prediction that he made in designing his experiment was called the scientific method.
If a tin is filled with hot water and sealed then covered with cold water What causes the tin to become dented?
The outside air pressure dents the tin. The water or air inside a sealed metal container will contract when cooled from the outside (by conduction through the can). When it was sealed, the pressure on the inside was the same as on the outside. But the contraction reduces the pressure on the inside, causing the external air pressure to squeeze the can, and possibly cave it in. This is widely demonstrated in another experiment using dry ice. A sealed gasoline can of about a gallon (4 liters) is placed on a dry-ice bed and cooled until the outside air pressure crushes the can.
What do you think would happen if a group of plant was placed in a sealed environment with air water and light but no animal?
it would die ! @
What is the worth of a almost empty sealed can of coke?
Nothing, there's no beverage in it. No one really wants an empty can.
