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

Problem that the laboratory
activity is designed to solve
timeline of genetics
Answer:
Explanation:
5000 BC
Demonstrating some understanding of inheritance, humans worldwide begin to selectively breed more useful varieties of livestock and crops, including wheat, maize, rice and dates
400 BC
Greek philosophers contemplate the mechanisms of human inheritance. Aristotle believes that traits acquired during life, such as injuries, can be passed to offspring. He also develops the theory of “pangenesis”, which attempts to explain how these traits are transmitted via particles called “gemules” to the reproductive cells
1859
Charles Darwin, himself a proponent of pangenesis, publishes On the Origin of Species – his explanation of evolution by natural selection. Darwin provides a plethora of evidence on how valuable traits become more common in a population, but does not provide any explanation for the mechanism of transmission of these traits
1866
Augustinian monk Gregor Mendel publishes his work on the patterns of inheritance in pea plants. His meticulous studies mark the birth of modern genetics. Mendel’s findings escape the notice of other researchers for over three decades
1882
Chromosomes are discovered by German biologist Walter Fleming, and named with the Greek prefix meaning “colour” because they become stained when cells are dyed
1902
Mendel’s research is rediscovered by botanists in 1900. US and German cell biologists then independently notice the link between Mendel’s “units of inheritance” and chromosomes. They conclude that hereditary information is contained within chromosomes
1905
The term “genetics” is created by British biologist William Bateson. The terms “gene” and “genotype” surface in 1909.
Sex chromosomes are discovered following work on butterflies and beetles
1910
US scientist Thomas Hunt Morgan is the first to discover a sex-linked trait, while studying the fruit fly Drosophila. The trait for eye colour, on the X chromosome, is also the first gene to be traced to a specific chromosome
1925
Studies show that X-rays can induce mutations in the genetic material
1944
A trio of US geneticists revisit work from the 1920s and prove that, in bacteria, DNA is the hereditary material, and not protein as was previously suspected
1951
Clear X-ray diffraction images of DNA are captured for the first time by British researcher Rosalind Franklin
1953
Building on Franklin’s work, biochemist James Watson and biophysicist Francis Crick at Cambridge University, UK, determine the now famous double-helix structure of DNA. They are awarded a Nobel prize in 1962 for their efforts.
1961
Crick and South African geneticist Sydney Brenner report that trios of DNA bases – called nucleotides – each hold the instructions for one of the 20 amino acids that combine to form proteins
1973
US researcher Herb Boyer uses enzymes to cut DNA and splice it into bacterial plasmids, which then replicate producing many copies of the inserted gene. This heralds the dawn of genetic engineering
1978
Genetically modified bacteria produce the hormone insulin
1983
The gene for an inherited disorder (Huntington’s disease) is mapped to a chromosome for the first time
1986
Kary Mullis in the US develops the Polymerase Chain Reaction (PCR), which allows researchers to produce many millions of copies of DNA molecules in just a few hours
1990
The international Human Genome Project begins, with the goal of sequencing the entire human genetic code
Gene therapy is used successfully for the first time, to treat a four-year-old girl with the rare hereditary immune disorder adenosine deaminase deficiency
1994
FlavrSavr tomatoes, genetically modified to have a long shelf-life is the first GM product to go on sale in the US. GM tomato puree goes in sale in the UK in 1996
1996
Baker’s yeast is the first (non-viral) genome to be completed, followed by the worm Caenorhabditis elegans in 1998 and then the plant Arabidopsis and fruit fly Drosophila in 2000
2000
Completion of the draft human genome is jointly announced by US firm Celera Genomics and the Human Genome Project (an international public consortium). The full sequence – comprising 30,000 to 40,000 genes – is completed in 2003
2003
