When a uranium nucleus breaks into fragments what type of nuclear reaction occurs?
In nuclear physics and nuclear chemistry, nuclear fission is a nuclear reaction in which the nucleus of an atom splits into smaller parts (lighter nuclei), often producing free neutrons and photons (in the form of gamma rays).
How does agarose gel electrophoresis work to separate DNA fragments based on their size?
Agarose gel electrophoresis separates DNA fragments based on their size by using an electric current to move the fragments through a gel made of agarose, a substance derived from seaweed. Smaller DNA fragments move faster through the gel, while larger fragments move more slowly. This separation occurs because the gel acts as a sieve, with smaller fragments able to navigate through the pores more easily than larger fragments. As a result, the DNA fragments are separated into distinct bands based on their size when viewed under ultraviolet light.
Why do atoms get smaller across a period?
Atoms get smaller across a period because the increasing number of protons in the nucleus pulls the electrons closer to the nucleus, resulting in a stronger attraction and a smaller atomic size.
What is a smaller atomic radius of beryllium be?
A smaller atomic radius for beryllium would result from an increased positive charge in its nucleus, leading to a stronger attraction between the nucleus and the valence electrons. This increased attraction pulls the electron cloud closer to the nucleus, resulting in a smaller atomic radius.
How does gel electrophoresis work to separate DNA fragments based on size?
Gel electrophoresis separates DNA fragments based on size by applying an electric field to move the fragments through a gel matrix. Smaller fragments move faster and farther than larger ones, resulting in distinct bands that can be visualized and analyzed.
How does the binding energy per nucleon vary in fission reactions?
In fission reactions, the binding energy per nucleon decreases as a heavy nucleus splits into smaller fragments. This is because the smaller fragments have a higher binding energy per nucleon compared to the original heavy nucleus.
Are platlets colorless?
Yes, platelets are colorless fragments of cells that help in blood clotting. They do not contain a nucleus and are smaller than red and white blood cells.
When a uranium nucleus breaks into fragments what type of nuclear reaction occurs?
In nuclear physics and nuclear chemistry, nuclear fission is a nuclear reaction in which the nucleus of an atom splits into smaller parts (lighter nuclei), often producing free neutrons and photons (in the form of gamma rays).
What are fission fragments?
When an atomic nucleus fissions, it splits into smaller atomic nuclei. These smaller atomic nuclei are referred to as "fission fragments." The unstable nucleus of a radioactive element can fission (split) into smaller nuclei, i.e. those of lighter elements. This can also release other atomic particles, as well as energy. In nuclear power and atomic weapons, the fission process is initiated to release the nuclear energy. Natural fission is a much rarer occurrence than radioactive decay.
What do you call the reaction where the atomic nucleus splits into fragments?
The reaction where an atomic nucleus splits into fragments is called nuclear fission. During this process, the nucleus of an atom, typically a heavy element like uranium or plutonium, absorbs a neutron and becomes unstable, leading to its division into two or more smaller nuclei, along with the release of energy and additional neutrons. This reaction is the principle behind nuclear power and atomic bombs.
When rocks are broken into smaller fragments?
soil
How do you measure the energy created by spliting a hydrogen atom?
You can't split a hydrogen atom, as the nucleus consists of only one proton, nothing else
When the nucleus disappears during prophase it fragments into which fuse to reform the nucleus during telophase?
When the nucleus disappears during prophase, it fragments into vesicles containing membrane and nuclear pore proteins. These vesicles then fuse together to reform the nucleus during telophase.
When the two main substances that make up a virus are broken into smaller fragments these fragments are what?
Amino acids and nucleotides
Are the DNA fragments in band 4 larger or smaller than those of band 1?
The size of DNA fragments in band 4 should be smaller than those of band 1. The fragments can be separated by electrophoresis, with the smaller fragments migrating farther than the larger ones.
When the two main substances that make up a virus are broken into smaller fragments these fragments are?
The two main substances that make up a virus are nucleic acid (DNA or RNA) and protein. When these substances are broken into smaller fragments, the nucleic acid fragments are called nucleotides, and the protein fragments are called amino acids.
Which fragements travel the fastest and farthest during electrophoresis?
The smaller DNA fragments travel faster and farther during electrophoresis compared to larger fragments. This is because smaller fragments experience less resistance from the gel matrix and are able to move more quickly through the electric field.
