enzymes degrade proteins, lipids, and large carbohydrates to smaller building blocks in the digestive tract. why must these macr
Rom4ik [11]

Amino acids, which serve as the "building blocks" of proteins, are disassembled. These tiny molecules can be absorbed through the stomach wall after being released.

<h3>Describe how the macronutrients in your diet are digested and then put back together to form the cell structure.</h3>

The principal macromolecules, from which all life is derived, are macrounits in our diet. The smaller subunits of these macromolecules must be broken down in order to be released. The circulatory system carries the digestively released components to the body's cells. These subunits serve as the building blocks for the macromolecules required for cellular structure and function, which are then put together by cells.

Proteins, lipids, and carbohydrates are examples of macromolecules.

The fact that all three macromolecules are hydrocarbons means that the majority of their atoms are made up of hydrogen and carbon.

Nitrogen atoms are found in proteins and in lipids.

Carbon atoms make up carbohydrates.

Simple carbohydrates are formed when complex carbohydrates are hydrated (by adding hydrogen and oxygen ions).

Dehydration of simple carbohydrates causes them to bind together in chains to create complex carbs. This can be reversed.

What type of rock is marble? Describe how a piece of marble is likely to change over several years. (8 points)
Viktor [21]

Marble is a metamorphic rock.

Marble is a metamorphic rock, that forms when limestone (another rock) reaches a certain pressure and heat. It's composed of mostly calcite, and some other minerals like pyrite, quartz, iron oxide, and granite.

Over several years, marble is supposed to wear down from acid rain/weathering.

Determine the volume of the figure shown below and round the answer to include the correct number of significant
Lorico [155]

Given,

l=5.80cm

h=2.35 cm

d=1.212 cm

Thus, the correct option is C.

<h3></h3><h3>What is volume?</h3>

The amount of three-dimensional space encircled by a closed surface is expressed as a scalar quantity known as volume. The amount of three-dimensional space encircled by a closed surface is expressed as a scalar quantity known as volume.

Using volume formula:  length × width × height:

5.80cm x 2.35 cm x 1.212 cm = 16.5 cm

Conclusion, the volume will be 16.5 cm.

When a hypothesis is supported by data within an experiment we say it has been
Harlamova29_29 [7]

A scientific hypothesis is the initial building block in the scientific method. Many describe it as an “educated guess,” based on prior knowledge and observation. While this is true, the definition can be expanded. A hypothesis also includes an explanation of why the guess may be correct, according to National Science Teachers Association.

Hypothesis basics

A hypothesis is a suggested solution for an unexplained occurrence that does not fit into current accepted scientific theory. The basic idea of a hypothesis is that there is no pre-determined outcome. For a hypothesis to be termed a scientific hypothesis, it has to be something that can be supported or refuted through carefully crafted experimentation or observation. This is called falsifiability and testability, according to the Encyclopedia Britannica.

A key function in this step in the scientific method is deriving predictions from the hypotheses about the results of future experiments, and then performing those experiments to see whether they support the predictions.

A hypothesis is usually written in the form of an if/then statement, according to the University of California. This statement gives a possibility (if) and explains what may happen because of the possibility (then). For example, if garlic repels fleas, then a dog is given garlic every day will not get fleas.

Testing a hypothesis

The primary trait of a hypothesis is that something can be tested and that those tests can be replicated, according to Midwestern State University. It is often examined by multiple scientists to ensure the integrity and veracity of the experiment. This process can take years, and in many cases hypotheses do not go any further in the scientific method as it is difficult to gather sufficient supporting evidence.

"As a field biologist my favorite part of the scientific method is being in the field collecting the data, but what really makes that fun is knowing that you are trying to answer an interesting question so the first step in identifying questions and generating possible answers (hypotheses) is also very important and is a creative process. Then once you collect the data you analyze it to see if your hypothesis is supported or not," Jaime Tanner, a professor of biology at Marlboro College, told Live Science.

A null hypothesis is the name given to a hypothesis that is possibly false or has no effect. Often, during a test, the scientist will study another branch of the idea that may work, which is called an alternative hypothesis, according to the University of California, Berkeley. 

During a test, the scientist may try to prove or disprove just the null hypothesis or test both the null and the alternative hypothesis. If a hypothesis specifies a certain direction, it is called one-tailed hypothesis. This means that the scientist believes that the outcome will be either with effect or without effect. When a hypothesis is created with no prediction to the outcome, it is called a two-tailed hypothesis because there are two possible outcomes. The outcome could be with effect or without effect, but until the testing is complete, there is no way of knowing which outcome it will be, according to The Web Center for Social Research Methods.
