When a food handler can effectively remove soil from equipment using normal methods, the equipment is considered what?
Answers
Answer:
Cleanable
Explanation:
Cleanability refers to the ease with which microorganisms or particles can be removed from the equipment used in food production. To be cleanable the roughness of the machine being employed in production is not expected to exceed 0.8μm.
The Atomic Force Microscope is used to measure the surface roughness of machines. Cleanability is important as it ensures that the machines used in food production are safe.
When a food handler can effectively remove soil from an equipment by using normal methods, the equipment is considered to be; Corrosion Resistant.
The soil referred to her would be dirt because we are talking about a food handler.
Now, if the food handler is finding it difficult to remove dirt from the equipment by using normal/regular methods, it means that the soil/dirt has succeeded in having some kind of chemical reaction with that equipment.If that is the case, then it means the equipment is undergoing corrosion because corrosion is defined as the gradual destruction of a metal by chemical reaction with the environment.Since we have established that inability to use normal method denotes corrosion, then if he can use normal methods to remove the soil effectively, then the equipment is said to be corrosion resistant.Read more at; https://brainly.in/question/40223031

Answers
Answer:
They are the same thing
6 pies are more in 60 to 89 cherries than 90 to 119 cherries, a bar graph is a graphical depiction of information, amounts, or numbers using bars or strips.
How to depict the bar graph?They are employed to contrast and compare various data kinds, frequencies, or other measurements of several categories of data.
The calculation of the bar graph in the given question.
For 60 - 89 cherries there are 10 pies
For 90 -119 cherries there are 4 pies
10 -4 = 6 pies
The image for the graph is attached below.
When displaying sections of data, bar charts should be used. As long as there aren't too many categories to compare, vertical bar charts can be useful for comparing several categories or discrete data, such as age groups, classes, schools, etc. They are quite helpful for time series data as well.
Therefore, there are 6 more pies in the 60 -89 cherries category than in the 90-119 category.

Pea plant clones are given different amounts of water for a three-week period. First pea plant receives 400ml. Second pea plant receives 200ml. Third pea plant receives 100ml. Fourth pea plant does not receive any extra water; the plant only receives natural ways of receiving water. The height of the pea plants is recorded daily. What is the independent variable?
A) the different amounts of water
B) the heights of the pea plant
C) the pea plants
D) the natural ways of receiving water
Answers
Answer: The independent variable is the different amount of water. The correct option is A.
Explanation:
A variable can represent age, a person, or an entity that can be measured. In statistics, it is simply defined as an attribute of an object to be investigated. There are different types of variables these includes:
--> Dependent variable and
--> Independent variable.
Dependent variables are simply the variables that are affected by the changes that occurs in the experiment. From the experiment they should include:
--> the height of the plant,
--> the size of the plant,
--> the number of leaves
---> if the plant survived or not (dead).
Independent variable are the variables that are changed in the experiment. A good example from the pea plant experiment is WATER. It is the aspect that is used to alter the dependent variable which is the height of the pea plant. I hope this helps, thanks!

Answers
Answer:
B. All carbon atoms have six protons and six electrons.
D. Atoms of some naturally occurring carbon isotopes may have six neutrons
Explanation:
Isotopes are atoms of the same elements having same atomic number but different atomic masses.
Atomic number is the number of protons (or electron number in neutral atoms) present in the atomic nucleus of the atom.
Atomic mass number is the sum of protons and neutrons present in the nucleus of the atom.
Considering the options above from the above definitions:
A. All carbon atoms have six neutrons is false because carbon-12, carbon-13 and carbon-14 has 6, 7 and 8 neutrons respectively.
B. All carbon atoms have six protons and six electrons is true because the atomic number of carbon is 12.
C. Atoms of all carbon isotopes have either more than 6 electrons or fewer than 6 electrons is false because atoms of all carbon isotopes have six electrons.
D. Atoms of some naturally occurring carbon isotopes may have six neutrons is true because atoms of carbon-12 have six neutrons.
E. Atoms of some naturally occurring carbon isotopes may have twelve neutrons is false because none of carbon-12, carbon-13 or carbon-14 have twelve neutrons.

the answer is b and d
Explanation:
1.) What gives water all its properties? 2.) What type of bond joins H2O to another H2O and forms cohesion? 3.) What property of water prevents rapid temperature change inside the body of organism? 4.) Which property of water allows water to attach to roots of plants for capillary action? 5.) Water is found in many compounds such as blood, saliva, sweat because of which property of water? 6.)Which property of water causes water to form drops? 7.)Which property of water helps maintain extreme temperature changes in an area? 8.) What happens to hydrogen bonds when water turns to ice? 9.) Why doesn't water break down fat? 10.)Which property of water causes surface tension? Cohesion, Adhesion, High heat capacity, high heat vaporization and polarity
Answers
Answer:
1. polarity
2. hydrogen bonding
3. High heat capacity
4. Adhesion
5. polarity
6. surface tension
7. high heat vaporization
8. hydrogen bonds form a rigid and stable network
9. Water is a polar substance and fat is a nonpolar substance.
10. Cohesion
Explanation:
Water is a polar molecule that is held together by hydrogen bonds to form strong cohesive forces. This accounts for the surface tension in water. Surface tension is the force acting on water that it makes to behave like a stretched elastic skin.
The polarity of water accounts for the fact that it is found in several parts of the body where it largely plays the role of a polar solvent.
High heat capacity of water enables it to function well in the area of thermoregulation in the body. High heat vaporization accounts for the fact that water helps maintain extreme temperature changes in an area.
When in solid state, the hydrogen bonded network in water becomes rigid and forms a very stable network of water molecules. Being polar, water does not interact with fat because like dissolves like.
In plants, the attachment of water to plant roots is known as adhesion and is necessary for the capillary movement of nutrients to plants via the root.
So this is a simple yes or no question
