matter changes identity

Answers

Answer 1

When bonds between molecules or atoms are created, disrupted, or both, chemical changes result.

This implies that a substance with a particular set of properties—such as melting point, color, flavor, etc.—becomes a substance with a different set of characteristics.

Physical alterations can often be reversed more easily than chemical changes.

We constantly surround ourselves with change. Chemists have categorized different sorts of modifications in the same way that they have categorized elements and compounds. Physical or chemical changes might be categorized as changes. Chemists investigate the transformations that matter can go through to learn a lot about the nature of stuff.

Physical changes and chemical changes are the two different types of changes that chemists examine.

2. A common theme in anatomy is "structure determines.
". (think relationship!)

Answers

Structure determines function.

The arrangement of something within an organism allows it to carry out its function. Relationships between structure and function are produced by natural selection. This is seen at every level of the biological organization hierarchy, from atoms to the biosphere.

For example, the hand

Function: We'll only concentrate on two of the many uses of the human hand: holding objects for power and for fine control (like a pencil) .Relationship between structure and function: The opposable thumb's capacity to touch all the fingers (called opposition) enables exquisite control. The power grip can be achieved by touching the fingers to the palm's base and wrapping the thumb above.

Hence, structure determines the function.

Tasha is researching the pharmacokinetics of amoxicillin. Which three questions should she aim to answer while doing her research? Why is it important for pharmacists and other healthcare professionals to be able to answer these questions?

Answers

The three questions that Tasha should aim to answer while doing her research on the pharmacokinetics of amoxicillin are: how is amoxicillin absorbed?, how is it distributed and how is it eliminated?

What is pharmacokinetics?

Pharmacokinetics is defined as what the body does to a drug when it's been taken. it is otherwise defined as the interaction of the body with the taken drugs.

When researching on the pharmacokinetics of a particular drug (amoxicillin), the questions that should be answered should be based on the phases of pharmacokinetics which include the following:

How is the drug absorbed?: This answers how the drug moves from the site of administration to the site of action.

How is the drug distributed?: This answers the journey of the drug through the bloodstream to various tissues of the body.

How is the drug eliminated?: This answers the removal of the drug from the body when it's action is being completed.

Whereas most medications are administered using the metric system, what is a
benefit of administering medication using the household measurement system?
It allows individuals to more easily administer drugs at home.
It is more accurate than the metric system.
It allows for more consistency between scientists from different regions.
The tools it uses are easily accessible when testing in a lab.

Answers

The benefit of administering medication using the household measurement system is option A. it allows individuals to more easily administer drugs at home.

Home weighing systems are systems that most of us use at home, usually in our kitchens. Home systems use drops teaspoons tablespoons ounces cups pints quarts gallons, and pounds measurements. The system is also the most commonly used measurement system in pharmacy calculations as it can be quickly and easily converted between different measurement systems.

In medicine, most measurements are based on clinical decisions. Developing diagnostic criteria for a disease assessing changes in patient status over time, and determining prognosis are clinical processes that require some form of observation and measurement either ad hoc or as part of a formal procedure. The metric system is called the International System of Units and is abbreviated as SI units. Ultimately, it will be the only system used for drug administration.

A rectangular block of land is three times as long as it is wide If the perimeter is 48 m, find its dimensions. ​

Answers

The length of the given rectangular block whose perimeter is 48 m is 18 m and width is 6 m.

Define Perimeter.

The perimeter of a shape refers to its whole diameter. It is the length of any geometric shape with a boundary or outline in two dimensions. It is possible for many figures to have equal perimeters depending on their proportions.

Let the width of the rectangular block be x.

So, the length of the rectangular block be 3x.

It is given that the perimeter of the rectangular block is 48 m.

Perimeter = 48 m

2 ( Length + Breadth ) = 48 m.

2 ( 3x + x ) = 48 m
Dividing both sides by 2.

4x = 24 m

Dividing both sides by 4.

x = 6 m.

So, the width of the rectangular block is 6 m and the length will be (3 × 6) m i.e., 18 m.

I don't mind.""Oh, I'm so glad. I know you and I are going to get along together fine. It's such a relief to talk when one wants to and not be told that children should be seen and not heard. I've had that said to me a million times if I have once. And people laugh at me because I use big words. But if you have big ideas you have to use big words to express them, haven't you?""Well now, that seems reasonable," said Matthew."Mrs. Spencer said that my tongue must be hung in the middle. But it isn'tit's firmly fastened at one end. Mrs. Spencer said your place was named Green Gables. I asked her all about it. And she said there were trees all around it. I was gladder than ever. I just love trees. And there weren't any at all about the asylum, only a few poor weeny-teeny things out in front with little whitewashed cagey things about them. They just looked like orphans themselves, those trees did. It used to make me want to cry to look at them. I used to say to them, 'Oh, you POOR little things! If you were out in a great big woods with other trees all around you and little mosses and Junebells growing over your roots and a brook not far away and birds singing in you branches, you could grow, couldn't you? But you can't where you are. I know just exactly how you feel, little trees.' I felt sorry to leave them behind this morning. You do get so attached to things like that, don't you? Is there a brook anywhere near Green Gables? I forgot to ask Mrs. Spencer that.""Well now, yes, there's one right below the house.""Fancy. It's always been one of my dreams to live near a brook.

I can't feel exactly perfectly happy becausewell, what color would you call this?"She twitched one of her long glossy braids over her thin shoulder and held it up before Matthew's eyes. Matthew was not used to deciding on the tints of ladies' tresses, but in this case there couldn't be much doubt."It's red, ain't it?" he said.The girl let the braid drop back with a sigh that seemed to come from her very toes and to exhale forth all the sorrows of the ages."Yes, it's red," she said resignedly.
