because gases do not conduct electricity under normal pressure so at pressure of 0.1-0.001 mmHg with very high potential difference of 5000 to 10000 volts gases conduct electricity and produce fluorescence on the wall of discharge tube and it also avoid the collision of cathode rays with the positive rays

The variable that the experimenter deliberately changes is called the independent variable. The thing you are observing as a result of the different 'values' or 'conditions' of the independent variable is called the dependent variable. If the experiment is well controlled, then you can have some confidence that changes in the dependent variable have come about directly as a result of your changes to the independent variable.

Peptide bonds are the bonds that hold two amino acids together in a protein chain. These bonds form between the carboxyl group of one amino acid and the amino group of another amino acid, resulting in the release of water molecules.

They are grown in Agar, as opposed to water (or any aqueous solution) because if the metal is grown quickly, as it would be in water, the crystals that are formed are hard to see, and their shape is usually undefined. However when they're grown in Agar jelly, the process is significantly slowed down, and after 1-2 days when you observe it, the crystals are usually larger and the shape can be clearly made out (providing you did the experiment right).

A plastic soda bottle is a good choice for an air pressure experiment with hardboiled eggs. It is durable, clear for observation, and easy to manipulate for creating changes in air pressure within the bottle. Make sure to use a bottle with a cap that can be sealed tightly to control the air pressure effectively.

Facts are pieces of information that can be proven true or valid, while figures and other evidence gathered through observation are known as data or empirical evidence. These data points help support or refute various claims or hypotheses.

Soap powder typically turns a pH indicator such as litmus paper to blue or purple, indicating that it is basic or alkaline in nature.

Errors in dependent motion of several particles in an experiment can be caused by factors such as inaccuracies in measuring equipment, external forces interfering with the motion of the particles, and human error in recording or analyzing data. It is important to carefully control these factors to minimize errors and ensure accurate results.

The haemin crystal experiment is commonly used to demonstrate the power of self-organization in biological systems, specifically in the formation of heme molecules. It shows how simple molecules can come together under the right conditions to form complex structures, providing insights into biological processes such as protein folding and assembly. Additionally, studying haemin crystal formation can provide valuable information for understanding diseases related to heme metabolism.

Yes, braces can rust if they are made of metal and come into contact with moisture or acidic substances. It is important to properly care for your braces by following your orthodontist's instructions for cleaning and maintenance to prevent rusting. If you notice any signs of rust on your braces, contact your orthodontist for further evaluation and treatment.

When climbing a mountain, the air density decreases due to the lower pressure at higher altitudes. This decrease in air density can affect breathing and energy levels, making it more challenging to climb as you reach higher elevations.

A rainbow is a phenomenon caused by the refraction, reflection, and dispersion of light in water droplets in the atmosphere. It is not considered a wave, but rather a spectrum of light wavelengths that are visible to our eyes.

The globe likely doesn't light up when removed from its holder because the holder contains the necessary electrical components like a power source or bulb connections to illuminate the globe. Without the holder, the globe lacks the functionality to light up on its own.

The variable that is intentionally manipulated or changed by the experimenter is called the independent variable.

Yes, real diamonds do not melt ice. Diamonds have a very high melting point of about 4,027 degrees Celsius (7,280 degrees Fahrenheit), much higher than the temperature required to melt ice.

Simply looking at a mirror requires reflection and refraction. By looking at a mirror, light reflects off of you and on to the mirror and back at you, and the light will refract throught the convex lenses in your eyes for you to see your reflected image.

You can also look through a microscope, because microscopes are filled with lenses and a few mirrors.

You can also put a stick in a glass of water to show refraction. Put the stick in at about 45 degrees, and the stick will look like it is broken in half, due to refraction. If you look at the the stick from under the cup at a corner, you can only see the part of the stick that's under the water, and if it's still in a 45-degree angle, it will have a relflection right on the water's surface, and both the stick and its reflection will form an angle of about 90 degrees. This is a way to prove the law of reflection.

Blood travels to the lungs to pick up oxygen and then circulates to the rest of the body to deliver oxygen and nutrients to cells and tissues. It then returns to the heart to be pumped back to the lungs for more oxygen.

I'm guessing that first you must during the experiment collect the data that you observed, then collect this data and organize it independent and dependent variable (The x-axis is the independent variable and the y-axis is the dependentvariable).

Deodorant typically does not dissolve in water as it is designed to be water-resistant in order to remain effective throughout the day. The ingredients in deodorant are usually oil-based or waxes that repel water, making it difficult for the product to dissolve in water.

The type of transfer that involves fast particles colliding with slower particles is known as momentum transfer. In these collisions, the kinetic energy of the faster particles is transferred to the slower particles, resulting in a change in their velocities. This transfer of momentum can have various effects, such as heating up the slower particles or causing them to move in a different direction.

We controlled the independent variable (the variable we manipulated) to observe its effect on the dependent variable (the variable we measured). We also controlled for any potential confounding variables that could influence the results. Additionally, we ensured consistency in experimental conditions to eliminate any extraneous variables that could impact the outcome.

Gender can influence certain aspects of memory, such as the types of information that are typically remembered more easily. Additionally, research suggests that hormonal fluctuations throughout the menstrual cycle can impact memory in women. However, individual differences within genders play a significant role, and both men and women are capable of strong memory performance.

Water is known as the universal solvent because it has the ability to dissolve a wide range of substances due to its polar nature and ability to form hydrogen bonds. While water may not dissolve absolutely everything, it is still able to dissolve a vast majority of substances encountered in nature, earning it the title of universal solvent.

Carboxylic acids are versatile compounds with various uses including in the food industry as preservatives and flavor enhancers, in the pharmaceutical industry as drug intermediates, and in the production of plastics and polymers. They also play a crucial role in biochemistry as key components of fatty acids and amino acids. Additionally, carboxylic acids can participate in a variety of chemical reactions due to the reactivity of their functional group.
