Answer:
y=10
Explanation:
Given the expression 7 - y = -3
First we have to collect all constant term to one side hence
7+3-y=0
10-y=0
10=y
y=10
Answer:
GACCTG (the fourth option)
Explanation:
To find the correct complementary strand, we need to know this simple rule:
T always pairs with A and C always pairs with G.
So whatever letter you have in the DNA strand, the complementary strand will have the complement to it. In this case, we have CTGGAC. The complement of C is G, for T it is A, and so on. Therefore, the correct complementary strand is GACCTG (the fourth option).
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

Answer:
They can not live on their own
Explanation:
The main difference between cells and viruses is that viruses need another cell to infect so that they can reproduce. Cells on the other hand can reproduce on their own.
