Measure the mass of an empty container 2. pour the desired liquid in to
this container and wait for it to settle. 3. measure the mass of the
container + liquid 4. subtract the empty container mass to find the
liquid's mass Note: some scales have a tare feature (it defines a weight
of zero), which you measure the container's mass, use the tare option,
and then pour the liquid and wait for it to settle. Also, when you use a
scale, in truth you measure weight. It then divides by the known
gravity field to find a "weight" in kilograms, which we accept to equal
the mass in kilograms. You only truly measure mass when using a balance.
It compares the torque on the balance arm of the object's weight to the
torque on the balance arm of a slide-able weight. A balance will record
the same mass in any gravitational field.</span>
Answer:
I think It A
Explanation:
I read about it, so take your chance.
the offspring of crosses between parents with different traits?. Such as, the process by which peas are allowed to self-pollinate and produce offspring identical to themselves. A specific characteristic that varies from one individual organism to another. The offspring of crosses between parents with different traits. The chemical factors that are passed from one generation to the next.
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
Dichotomous Keys are used to find out what type of animal,plant,fungi,prokaryote,eukaryote,or bacteria an organism is. A branching diagram is used to find what domain,kingdom,phylum,class,order,family,genus,species an organism belongs in.
