ATP is produced by multiple cellular composition. ATP is synthesized from ADP and phosphate is formed by the process of cellular respiration. Mostly it is produced by enzymes present in the cell. These enzymes convert phosphate into ATP.

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

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.

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.

Answer:

A. Both are unicellular organisms that lack a membrane-bound nucleus.

Explanation:

Bacteria and archaea are both prokaryotes. Prokaryotes are always single celled organisms. They also do not have a defined-nucleus. These features differentiate them from eukaryotes, which all have a membrane-bound nucleus. Some eukaryotes are also multicellular (but not all)

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.

C.) Aerobic respiration produces more ATP than anaerobic respiration.

Explanation:

Aerobic respiration is a cellular respiration reaction that requires the presence of oxygen. The electron transport chain in this reaction creates 32 ATP, making for a total of 36 ATP gained by aerobic respiration.

Answer:

The smallest particle is the electron (option D).

Explanation:

The electron is a subatomic particle, which is part of an atom and has a negative electrical charge.

Electron is a small particle, if compared to protons -electrically positive particles- whose size is about 1800 times bigger. In fact, the electron is the smallest particle inside the atom.

    According to this, the other options, atom, nucleus and proton are structures larger than an electron.

An example of physical change is the freezing of water, while an example of chemical change is the burning of coal. Thus, the correct option for this question is D.

Physical change may be defined as a type of change that only involves alterations in the physical properties of the matter. Examples include the boiling of water, freezing of water, etc.

A Chemical change may be characterized as a type of change that only involves alterations in the chemical properties of the matter. Examples include burning coal, rusting iron, mixing acids and bases, etc.

In a physical change, there is no new substance is synthesized, while in a chemical change one or more new substances are formed.

Therefore, freezing water is an example of physical change, while burning coal is an example of chemical change. Thus, the correct option for this question is D.
