PLEASE HELP ASAP!!! IF YOU HELP YOUR MY BEST FRIEND!!!
can you please write a paragraph on how to write a lab report

Answers

Explanation:

A typical lab report would include the following sections: title, abstract, introduction, method, results and discussion. Title page, abstract, references and appendices are started on separate pages (subsections from the main body of the report are not).

How do you start a lab report?

Sometimes an introduction may contain background information, briefly summarize how the experiment was performed, state the findings of the experiment, and list the conclusions of the investigation. Even if you don't write a whole introduction, you need to state the purpose of the experiment, or why you did it.

Answer:

Explanation:

The title says what you did. It should be brief (aim for ten words or less) and describe the main point of the experiment or investigation. An example of a title would be: "Effects of Ultraviolet Light on Borax Crystal Growth Rate". If you can, begin your title using a keyword rather than an article like "The" or "A".

Usually, the introduction is one paragraph that explains the objectives or purpose of the lab. In one sentence, state the hypothesis. Sometimes an introduction may contain background information, briefly summarize how the experiment was performed, state the findings of the experiment, and list the conclusions of the investigation. Even if you don't write a whole introduction, you need to state the purpose of the experiment, or why you did it. This would be where you state your hypothesis.

List everything needed to complete your experiment.

Describe the steps you completed during your investigation. This is your procedure. Be sufficiently detailed that anyone could read this section and duplicate your experiment. Write it as if you were giving direction for someone else to do the lab. It may be helpful to provide a figure to diagram your experimental setup.

Data

Numerical data obtained from your procedure usually presented as a table. Data encompasses what you recorded when you conducted the experiment. It's just the facts, not any interpretation of what they mean.

Results

Describe in words what the data means. Sometimes the Results section is combined with the Discussion.

Discussion or Analysis

The Data section contains numbers; the Analysis section contains any calculations you made based on those numbers. This is where you interpret the data and determine whether or not a hypothesis was accepted. This is also where you would discuss any mistakes you might have made while conducting the investigation. You may wish to describe ways the study might have been improved.

Conclusions

Most of the time the conclusion is a single paragraph that sums up what happened in the experiment, whether your hypothesis was accepted or rejected, and what this means.

Figures and Graphs

Graphs and figures must both be labeled with a descriptive title. Label the axes on a graph, being sure to include units of measurement. The independent variable is on the X-axis, the dependent variable (the one you are measuring) is on the Y-axis. Be sure to refer to figures and graphs in the text of your report: the first figure is Figure 1, the second figure is Figure 2, etc.

Edit: A typical lab report would include the following sections: title, abstract, introduction, method, results and discussion. Title page, abstract, references and appendices are started on separate pages (subsections from the main body of the report are not). How do you start a lab report? Sometimes an introduction may contain background information, briefly summarize how the experiment was performed, state the findings of the experiment, and list the conclusions of the investigation. Even if you don't write a whole introduction, you need to state the purpose of the experiment, or why you did it.

Answer: keeping a detailed record of the procedure and results of a scientific, conducting a experiment to confirm the effects of gravity on earth, solving a expression in steps using the order or operation

Explanation:

Descartes's rules for scientific reasoning include keeping a detailed record of all the procedures and results of a scientific experiment, conducting an experiment to confirm the effects of gravity on Earth, and Solving an expression in steps using the order of operations. Thus, the correct options are A, B, and E.

What are Descartes's rules for scientific reasoning?

Descartes described the important rules which he established to make sure that the conclusions made in the experiment are true. These rules are as follows:

1. accepting nothing as true that is not self-evident, and perform experiment to prove anything

2. Divide the problems into their simplest parts, and keeping the detailed records of each and everything

3. Solve problems by proceeding in a stepwise order of operations in a scientific study.

Therefore, the correct options are A, B, and E.

Since the elephant’s diet consists of play material only, where would the elephant get the missing element needed to make collagen (or any protein)?

Answers

Answer:

The elephant is a herbivores animal and feeds on plant material that consist of cellulose. Collagen is a type of protein  that is absent in plant material and only found in skin, tendons, bones and muscles. The elephant also requires collagen to replace or repair their skin cell in every 2 weeks.

As elephants are unable to consume meat that contains collagen, they get collagen or protein from the plant material only with the help of bacteria or enzymes present in its guts. The bacteria having enzymes that helps in the breakdown of cellulose and access the proteins, fat or sugar present in the plant cell.

Elephants get collagen and other proteins from the vegetables they consume.

We can arrive at this answer because:

Collagen is essential for the maintenance of the skin.However, collagen is found in large amounts in meat.Few vegetables have collagen and elephants only feed on vegetables.However, the demand for collagen in the elephants' body is met by feeding on vegetables rich in cellulose and vitamin C.

When cellulose is digested and vitamin C is used in the body, collagen production is stimulated.

What force will a cannonball have if it has a mass of 4 kg and accelerates it to 110 m/s²?

Answers

I’m assuming the cannon ball is being shot directly horizontally. If there’s an angle, this answer will be wrong. But either way, you want to use Newton’s Second Law of motion.
F = ma, you could change this to a = F/m to get a better understanding of the equation. Acceleration and force are directly proportional. The mass is inversely proportional to acceleration. This means the net force will be in the same direction as the acceleration.

Alright back to the problem:
F = 4kg*110m/s^2
F = 440N

the answer for this question is b

Explanation:

The partial negative charge on the oxygen atom, because it pulls electrons from the hydrogen atoms, describes the polarity in the water molecule.

What do you mean by polarity?

In chemistry, polarity is the difference in electric charge that results in a molecule or its chemical groups having an electric dipole moment,  a negatively charged end and a positively charged end.

For example, the carbon-oxygen bonds in carbon dioxide are both polar, with the carbon atom having a partial positive charge  and  the more electronegative oxygen atom having a partial negative charge.

Polarity is when an entity contains two separate and opposite poles that can either attract or repel each other. The term is often used in electricity, magnetism, chemistry, and electronic signaling to describe the flow of electrons.
