In the nucleus, DNA is often found wrapped up and linked to a variety of histone proteins in a structure called chromatin that is loosely confined. Chromatin coils tightly and condenses to produce chromosomes just before a cell divides.

Chromosomes do not form from DNA when cells are not dividing. Instead, it is discovered in a looser form known as chromatin. Contrary to chromosomes, chromatin is DNA in an uncondensed form and lacks a recognisable structure. The nucleus of eukaryotic cells houses chromatin.

Chromosomes in eukaryotic cells are made of chromatin, a compound of DNA and proteins. Nuclear DNA is extremely compressed and wrapped around nuclear proteins in order to fit inside the nucleus; it does not exist as free linear strands. There are two varieties of chromatin.

1. · Explain the origin of coal and name its various varieties.
scZoUnD [109]

Answer:

Coal gas is a flammable gaseous fuel made from coal and supplied to the user via a piped distribution system.It is produced when coal is heated strongly in the absence of air. ... Facilities where the gas was produced were often known as a manufactured gas plant (MGP) or a gasworks.

Coal tar is a thick dark liquid which is a by-product of the production of coke and coal gas from coal. It has both medical and industrial uses. Medicinally it is a topical medication applied to skin to treat psoriasis and seborrheic dermatitis (dandruff). It may be used in combination with ultraviolet light therapy.

: a bituminous coal suitable for making into coke.

In your own words, explain why a virus such as the rhinovirus, which relies on close contact to spread, might evolve to favor le
Zielflug [23.3K]

Rhinoviruses are transmitted through the air or via contact. We might expect this sort of transmission to require a fairly healthy host (one who gets out and comes into contact with others) and, hence, to select against virulent strains. If we take precautions and try to stay away from people or avoid any contact with people, more hand-washing stations, increased attention to sanitization, and isolation of patients will help to reduce the transmission of the disease and, in the process, may favor the evolution of less virulent strains of the virus.

Nataly_w [17]

Answer:

Stored water - gravitational energy

Water fall - kinetic energy

Turbine - kinetic energy

Powerlines - electric energy

Explanation:

Dams are used to store or hold water for hydroelectric power plants. This stored water which has gravitational energy is a form of potential energy.

When the water is left to fall and run fast through the turbine, the gravitational energy is transformed into kinetic energy which makes the turbine to spin.

As the turbine spins, kinetic energy that is produced also powers the shaft of the engine in the electric generator, which produces electricuty.

Kinetic energy is transformed to electric energy and transmitted along powerlines.

*See attachment below for labelled energy that is being transformed at several points.
