The amount of DNA that is associated with each nucleosome is a approximately 200 bp. This is determined by treating chromatin wwith a certain enzyme that cuts DNA. This enzyme is called DNases. Every chromosome has hundred of thousands of nucleosomes that are joined by DNA strands that pass between them.

<u>Answer:</u>

A nucleosome is a structure that is consists of DNA wrapped around 8 sub-units of a protein namely the histone protein. There are packing of these materials around the proteins decide the transcription site of most of the RNA.

The amount of DNA that is packaged inbetween is about 1.7 turns of the DNA that contains 146 base pairs and about 20 base pairs are in between the turns which sums it to 166 base pairs associated with each nucleosome.

What is the medical term for the process or procedure that destroys or inhibits disease-causing microorganisms to prevent infect
Simora [160]

Answer: Sterilization.

Explanation:

Sterilization is the process that kills, or deactivates all forms of life so then a product is considered free of viable microorganisms. This process must be designed, validated and carried out to ensure that it is capable of eliminating the microbial load of the product.

Since sterility cannot be demonstrated without causing the complete destruction of the products, <u>sterility is considered when the probability of a product being contaminated is acceptably remote.</u> A critical product is considered sterile when the probability of a microorganism being present in an active or latent form is equal to or less than 1 in 1,000,000 (sterility safety factor 10^-6).

Agents that kill microorganisms are called microbicides or more commonly called "germicides". If the agent kills bacteria, it is called a bactericide. And if it kills fungi, then it is called a fungicide. It is important to consider than <u>after an exposure of the sterilized object to the air or its surroundings, it will have become contaminated again with microorganisms.</u>

Examples of sterilization include physical methods and chemical methods. Physical methods include:

  • Wet heat (in steam autoclave)
  • Dry heat (in sterilization oven)
  • Radiation (gamma radiatio, electron beam, X-ray, ultraviolet, microwave, white light)

Chemical methods include a variety of chemicals in liquid and vapor form, for example:

  • Hydrogen peroxide
  • Chlorine dioxide
  • Ozone gases
  • Ethylene oxide
  • Propylene oxide
  • Peracetic acid

Which term specifically describes the categorization of people into ethnic groups without taking into account individual differe
zysi [14]

Answer: D) Stereotyping

Choice A is false because this involves denying a person to do something based on factors such as religion, race, ethnicity, etc.

Choice B is false because this term involves a crime or suspected crime being committed, or about to be committed. And it also makes the assumption based on a person's race.

Choice C is false since segregation is the separation of people usually by race or ethnicity. Though you could have class based segregation (eg: rich vs poor) and other forms.

Choice D is true because stereotyping is where you lump a bunch of people together based on cultural or societal assumptions. Usually it's in the form of "all ___ people do such and such" where you fill in the blank with a specific race or culture.

Define the term excretion.
Luba_88 [7]

Answer:

Excretion is a process in which metabolic waste is eliminated from an organism. In vertebrates this is primarily carried out by the lungs, kidneys, and skin.

Carbon dioxide

The liver regulates most chemical levels in the blood and excretes a product called bile. This helps carry away waste products from the liver. All the blood leaving the stomach and intestines passes through the liver. The liver processes this blood and breaks down, balances, and creates the nutrients and also metabolizes drugs into forms that are easier to use for the rest of the body or that are nontoxic.
