Answer:

Three mineral components of soil are bits of plant material, dead organisms and silt particles.

Explanation:

Minerals that is present in the soil comes from the decomposition of dead bodies of plants and animals. Some minerals also comes from the surrounding rocks.

Silt is produced from mineral rock and its size is larger than clay and small than sand particles. The minerals comes from the above sources is utilized by the plants.

What happens to RNA polymerase II after it has completed transcription of a gene? a. It begins transcribing the next gene on the
Over [174]

The correct answer is: b. It is free to bind to another promoter and begin transcription

Transcription is the first step of gene expression in which DNA molecule is copied (transcribed) into RNA (mRNA) by RNA polymerase. The process of transcription is divided into three phases:

1. Initiation

• RNA polymerase with transcriptional factors bind to gene promoter  

• RNA polymerase unwinds DNA double helix (transcription bubble is formed)

2. Elongation

• RNA polymerases adds nucleotides complementary to DNA  

3. Termination

• RNA polymerase gets to stop codon (transcribes a sequence of DNA known as a terminator)

• Formed complementary RNA strand is released from DNA-RNA complex.

RNA polymerase is also released and can transcribe some other gene by binding to its promotor. RNA polymerase will transcribe just the genes whose products are needed at a particular moment.

Explain the difference between fire resistance and flame spread. describe the hazards firefighters should be aware of during the
Kaylis [27]

Fire resistance is where the amount of time that material has withstood a standard fire exposure whereas flame spread is the speed at which a flame spread along the surface of a specific material and is considered as the difference between fire resistance and flame spread.

Fire resistance is the resistance to fire that is for a particular specified time and is under circumstances of standard heat intensity. It will not structurally fail or else allow the transition of heat and also not permit the side away from the fire so as to become hotter than a temperature that is specified well.

Flame spread is described as the surface burning characteristics enhanced by building materials. It is the most tested property of the fire performance of a material.

Firefighters should be aware of the growth and spread of a fire as they face respiratory hazards in emergency situations which include oxygen deficiency,  temperature elevation, smoke as well as toxic atmospheres. This can also affect both the physical and mental effects of the firefighter and would be worse if proper respirator precautions are not followed.

This indicates that firefighters are regularly exposed to certain concentrations of hazardous materials that include carcinogenic products such as carbon monoxide, benzene, sulphur dioxide, hydrogen cyanide, aldehydes as well as particulates.
