What is dissymmetry in stereochemistry?

I'm assuming dissymmetry means asymmetry here.

Symmetry in chemistry is a lot like symmetry in mathematics. If a certain molecule is identical to its mirror image, then it is said to be symmetrical.

Asymmetry means the opposite. An asymmetric molecule is not identical to its mirror image.

Our hands are an example of asymmetry. Look at your two hands. You will see that they are mirror images of each other. However, they are not exactly the same. Whereas, the thumb on the left hand is on the right, the thumb on the right hand is on the left.

In chemistry, an example is 1-bromo 1-chloro ethane. If you draw its structure in the tetrahedral shape, you will see that 4 different groups are attached to the second carbon. Now draw its mirror image. Are they the same in 3D? No.

What is the source of energy used by geothermal power plants?

A thorough explanation of the geothermal energy would take a lot of discussion. Briefly; the Earth's core is molten rock (read very hot). The heat rises to the surface in multiple ways. Geothermal power plants make use of this heat (geothermal energy) to generate electrical power.

What are major gridlines?

Gridlines on a chart indicate values. You will see them on bar charts, column charts and others. Major gridlines show more significant values, like having a major gridline to indicate intervals of 10. So there would be on at 10, one at 20, one at 30 and so on. You can also have minor gridlines which will be thinner and could be at more frequent intervals.

Can electro magnet magnetize and demagnetize soft iron?

Yes, they can magnetise soft iron. Not sure about demagnetising though. I assume that if more than one or two were placed around the soft magnet, it could demagnetise it..

However, the soft iron would need to be 'hit' so that the poles in the iron can allign with the magnetic fields due to the electro magnet.

Which field can not be blank?

Any and all required field(s) cannot be left blank.

Where does mold on leather shoes come from?

Mold on leather shoes usually comes from moisture. When leather shoes are exposed to damp conditions or are not stored properly in a dry, well-ventilated area, it creates an environment where mold can grow and thrive. It's important to keep leather shoes dry and clean to prevent mold growth.

What are countries to have deposits of oil?

Some countries known for having significant deposits of oil include Saudi Arabia, the United States, Russia, Canada, Iraq, and Iran. These countries are major players in the global oil market due to their abundant oil reserves.

Are plastics produced with the help of bacteria?

Yes, some companies are using bacteria to produce biodegradable plastics as an alternative to traditional plastics. These bacteria are genetically engineered to produce polymers that can be used in place of petrochemical plastics.

What is a type of technology that studies the hydrosphere?

Oceanographic technology is used to study the hydrosphere, which includes instruments like buoys, satellites, and research vessels to measure currents, water properties, and marine life. These technologies help scientists understand the dynamics of oceans and their impact on climate patterns and ecosystems.

What is the cost of geothermal technology?

How many lives has the lightning rod saved?

It is difficult to provide an exact number, but lightning rods are estimated to save thousands of lives each year by redirecting lightning strikes away from buildings and structures. Their purpose is to provide a safe path for lightning to follow to the ground, reducing the risk of fires, explosions, or injury.

Where is mechanical energy on a roller coaster?

Mechanical energy is used on the chains that pull the roller coaster cars up the tallest incline, which is typically located at the start of the track. Mechanical energy is also used in the braking system that slows the cars to a stop at the end of the track.

What conclusions did Gregor Mendel reach based on his observations of pea plants?

Gregor Mendel concluded that characteristics in pea plants are determined by discrete units (now known as genes) that are passed down from parents to offspring. He also formulated principles of inheritance, such as the law of segregation and the law of independent assortment, which laid the foundation for the science of genetics.

Why is time called time?

The word "time" comes from the Old English word "tīma," which meant a period or stretch of time. It likely originated from the Proto-Indo-European root "di-" meaning to divide, which reflects how time is divided into moments and intervals.

What is cell sectoring?

In cellular telephone system, co-channel interference can be decreased by replacing a single omni directional antenna with several directional antennas, each radiating within a smaller area.In sectoring,we keep unchanged cell radius & seek methods to decrease D/R ratio.By D/R ratio,SIR increase so we use directional antennas.

remember D/R is co-channel reuse ratio & SIR is signal to interference ratio

How has technology changed the way biologists study living things give an example?

Technology has made it possible for biologists to study living things right to their smallest elements. The microscope is a good example of a tool that allows biologists to study the most minute elements of all creatures.

What advantages does bioluminescence have over incandescent as a way for living organisims to produce light?

Bioluminescence is more energy-efficient than incandescent light because it produces light through chemical reactions rather than heat. It also doesn't require a constant power source since organisms can control when they emit light. Additionally, bioluminescence can be used for communication, camouflage, and attracting prey, giving organisms a survival advantage.
