Difference between x-rays and gamma rays?The difference between gamma rays and X-rays is in the frequency of the electromagnetic radiation. Gamma rays and X-rays are both types of electromagnetic radiation, and gamma rays are higher on the frequency spectrum, and have more energy than X-rays. Use the links below for more information.


1.Gamma rays cause more harm to human body than the X- rays.
2.Gamma rays have shorter wavelengths than the X-rays.
3.X rays are emitted by the electrons outside the nucleus, and gamma rays are emitted by the excited nucleus itself.
4.X rays are used in hospitals for taking X-rays but gamma rays are not.

Difference Between Fission and FusionFission and fusion are two different types of reactions in which large quantities of energy are released. Though energy is released during both fission and fusion reactions, the main difference is that fission is the process of splitting of an atom into two or smaller particles and fusion is the fusing or joining together of two or more smaller atoms to form a larger one.

Difference Between Stars and Planets1.Planets are stars are both heavenly bodies mostly observable to the naked eye.
2.Stars are large collections of gas that have a nuclear reactor at their core, whereas planets can be almost as large but lack the nuclear reactor.
3.Stars are the first to form when a new solar system is being created and planets are created later within the orbit of the star.
4.Throughout history mankind has been observing both stars and planets.

Difference Between Pollination and FertilizationFertilization and pollination are both natural processes.
Pollination is the prerequisite of fertilization. Fertilization cannot occur without pollination and pollination will be useless if fertilization will not take place.
In the process of pollination, external factors (pollination agents) may be needed. Whereas in the fertilization process, only the pollen grains and the flower’s reproductive system are needed to make it work.
Answer
Pollination is the spreading of pollen from the male to the female part of a flower.

Fertilization is the sperm and egg joining to form a zygote.

Pollination is the transfer of pollen to the ovule. Although it is a prerequisite to fertilization, several events must happen before fertilization occurs. Pollination is when pollen reaches the plant by wind or insect, whereas fertilization occurs when that pollen reaches the ovule and starts the beginnings of a new organism.

Telescope vs MicroscopeTelescope and Microscope are two scientific instruments that serve their purposes differently. One of the main differences between a telescope and a microscope is that a telescope is used to view things that are far whereas a microscope is used to view things that are very near.

Difference Between Antibiotics and Vaccines1)Vaccine kills virus while antibiotics kill bacteria.
2)Vaccine is taken once and has permanent effect whereas antibiotics work during the time of disease.
3)Antibiotics are available in different forms like tablets, capsules, drops or ointments. Vaccines can be given orally or through injection.
4)Vaccines are preventive method that is taken before getting infected. Antibiotics are taken after getting infected.

Bit vs ByteIn computing, bit is the basic unit of information. Simply, a bit can be seen as a variable that can take only one of two possible values. These two possible values are ‘0’ and ‘1’ and interpreted as binary digits. The two possible values could also be interpreted as logical (Boolean) values, which are ‘true’ and ‘false’. Byte is also a unit of information used in computing. One byte is equal to eight bits. Byte is also used as a data type in several programming languages such as C and C++.

Difference between RAM and ROM• RAM is Random Access Memory, while ROM stands for Read Only Memory.
• RAM is volatile and is erased when the computer is switched off. ROM is non-volatile and generally cannot be written to.
• RAM is used for both read and write while ROM is used only for reading.
• RAM needs electricity to flow to retain information while ROM is permanent.
• RAM is analogous to a blackboard on which information can be written with a chalk and erased any number of times, while ROM is permanent and can only be read. One example is BIOS (basic input output system) that runs when computer is switched on and it prepares disk drives and processor to load OS from disk.

Pandemic is defined when there is a growing number of population and all part of the world is affected by an infectious disease.
In epidemic an illness present in a population more than it should normally occur and only several people show symptoms in certain regions of the country.
Endemic: a disease that exists permanently in a particular region or population. Malaria is a constant worry in parts of Africa.
Epidemic: An outbreak of disease that attacks many peoples at about the same time and may spread through one or several communities.
Pandemic: When an epidemic spreads throughout the world.

What is the difference between photosynthesis and respiration
Answer:
Improve
Photosynthesis is the process which the chlorophyll uses carbon dioxide, water and light to create oxygen and glucose. Glucose is food for organisms that make their own food. Chlorophyll is found in the chloroplasts inside the leaves of any plant or green organism. The organisms synthesize carbohydrates from carbon dioxide and water to create glucose.

Respiration is the process which living things inhale and exhale air. They absorb oxygen from inhaled air and give out carbon dioxide as waste in exhaled air (which are again used by plants in photosynthesis - this is the carbon cycle).



Difference Between Herbivores and Carnivores1. Herbivores refer to animals that consume only plant products. Carnivores are animals that consume the flesh and meat of other animals, for food.
2. Carnivores have sharp incisors and canines, for their teeth help them to tear their prey’s flesh. Herbivores have flat, spade-shaped canines, and dull, short incisors, to help them grind plant leaves, seeds and grains.
3. Herbivores merely utilize their mouths for consuming food, which is why they only have small mouth openings. Carnivores use their teeth as a weapon, making it necessary for their mouth openings to be relatively larger in ratio to their head size

What is the difference between a Dam and a Barrage?Answer:
Improve
Both the dam and barrage are barriers constructed across a river or natural water course for diverting water into a canal mainly for purposes of irrigation, water supply etc. or into a channel or a tunnel for generation of power.
In case of a barrage, its entire length across the river i.e. between the banks is provided with gates having their bottom sill near the river bed level. Thus, the storage behind the barrage is solely created by the height of the gates.
The dam on the other hand has spillway gates almost near its top level and the storage behind the dam is mainly due to the height of concrete structure and partially due to the gate height.
In both the cases, however, the number and size of gates is adequate to pass the design flood during monsoons.

A dam stores surplus flood water and distributes this additional water through the power / irrigation tunnels in the dam or through the canals from its reservoir. In both cases it is the stored water that is distributed, and not river water which continues to flow normally as before.
It is at the barrages, for there is neither reservoir nor storage, that the canals take water directly from the rivers. Simply it can be differentiated that Dams add water , but barrages subtract it.

difference between multimeter and telemeterA telemeter is a device used to remotely measure a quantity. Telemeters are generally the physical devices used in telemetry. Electronic devices are widely used in telemetry and can be wireless or hard-wired, analog or digital. Other technologies are possible, however, such as mechanical, hydraulic and optical.
A multimeter or a multitester, also known as a or VOM (Volt-Ohm meter), is an electronic measuring instrument that combines several measurement functions in one unit.
difference between Nucleon and photonIn physics, a photon is an elementary particle, the quantum of the electromagnetic interaction and the basic unit of light and all other forms of electromagnetic radiation.
In physics, a nucleon is a collective name for two particles: the neutron and the proton. These are the two constituents of the atomic nucleus.

What is the difference between an asteroid, comet, meteoroid, meteor and meteorite?Asteroid: A relatively small, inactive body, composed of rock, carbon or metal, which is orbiting the Sun.

Comet: A relatively small, sometimes active object, which is composed of dirt and ices. Comets are characterised by dust and gas tails when in proximity to the Sun. Far from the Sun it is difficult to distinguish an asteroid from a comet.

Meteoroid: A small particle from an asteroid or comet orbiting he Sun.

Meteor: A meteoroid that is observed as it burns up in the Earth's atmosphere - a shooting star.

Meteorite: A meteoroid that survives its passage through the Earth's atmosphere and impacts the Earth's surface.

Difference Between Chemotherapy and RadiotherapyThe main object of both treatment is to kill all the cancer cells, but by different methods to ensure no cancerous cell is left behind in the disease spot.

Chemotherapy - Chemotherapy is done by giving chemical drugs which can kill the cancer cells. Chemotherapy is a systemic therapy; this means it affects the whole body by going through the bloodstream. The purpose of chemotherapy and other systemic treatments is to get rid of any cancer cells that may have spread from where the cancer started to another part of the body.

Chemotherapy is effective against cancer cells because the drugs love to interfere with rapidly dividing cells. The side effects of chemotherapy come about because cancer cells aren't the only rapidly dividing cells in your body. The cells in your blood, mouth, intestinal tract, nose, nails, vagina, and hair are also undergoing constant, rapid division. This means that the chemotherapy is going to affect them, too.

Radiation Therapy - Radiation therapy is one of the most common treatments for cancer. It is often part of the main treatment for some types of cancer, such as cancers of the head and neck, bladder, lung, and Hodgkin disease. Many other cancers are also treated with radiation therapy. Thousands of people become free of cancer after receiving radiation treatments, either alone or combined with other treatments such as surgery or chemotherapy.
All cells, whether cancerous or healthy, grow and divide to form new cells. But cancer cells grow and divide more quickly than many of the normal cells around them.

Unlike chemotherapy, which exposes the entire body to cancer-fighting drugs, radiation therapy is usually a local treatment. It affects only the part of the body being treated. In the case of radioactive substances that are given in the vein or by mouth, the radiation does travel throughout the body.

Generally the combination of both Chemo and Radiation treatments are given to the patient to ensure that all the cells are killed. -

difference between spring tides and neap tides?Spring Tides When the moon is full or new, the gravitational pull of the moon and sun are combined. At these times, the high tides are very high and the low tides are very low. This is known as a spring high tide. Spring tides are especially strong tides (they do not have anything to do with the season Spring). They occur when the Earth, the Sun, and the Moon are in a line. The gravitational forces of the Moon and the Sun both contribute to the tides. Spring tides occur during the full moon and the new moon.
Neap Tides During the moon's quarter phases the sun and moon work at right angles, causing the bulges to cancel each other. The result is a smaller difference between high and low tides and is known as a neap tide. Neap tides are especially weak tides. They occur when the gravitational forces of the Moon and the Sun are perpendicular to one another (with respect to the Earth). Neap tides occur during quarter moons.
