They figured out the DNA sequence from the amino acid sequence

According to Keplers first law of 1618 which has not been repealed yet, the planets each move in an elliptical orbit with the Sun occupying one focus. The shape of an ellipse is described by the eccentricity. For low eccentricity such as the planets' orbits have, the orbit is very close to being a circle but the most significant difference is that the Sun is off-centre.

That DNA molecule is a double helix-two strands twisted around each other, like a winding staircase

Greg Wendel was the person who developed the cell theory in recessive and dominant traits. He studied generation to generation on plants and saw which traits would show up in the next generation he discovered how traits showed up from parents to offspring.

because they need to be able to think outside the box otherwise they will have trouble as a scientist. thinking outside of the box is part of there job. If they don't be creative then they can't come up with real scientist ideas.

Rock Type and Structural Similarities

When the continents are reassembled, the mountain chains from a

continuous belt - having the same rock types, structures and rock ages.

Paleoclimatic Evidence

Glacial till of the same age is found in southern Africa, South America,

India and Australia - areas that it would be very difficult to explain the

occurrence of glaciation.

At the same time, large coal

deposits were formed from tropical

swamps in N. America and

Europe.

Pangaea with S. Africa centered

over the South Pole could account

for the conditions necessary to

generate glacial ice in the

southern continents.

In addition, the areas with

extensive coal deposits from the

same time period occur in regions

that would have been equatorial

Scientists who study classification (taxonomy) are known as taxonomists.

scientist classify parts of an ecosystem by biotic things (living things) and abiotic things ( nonliving things).

In 1803, John Dalton published his atomic theory, which proposed that all matter is made up of small, indivisible particles called atoms. This theory laid the foundation for modern chemistry and is considered a significant contribution to the field of science.

1. It is fitted on to the end of a pipette, a graduated glass tube used to measure varying volumes of liquid, and is used to draw up the liquid safely.

The ancient Greeks knew (most likely discovered too) the earth was not flat contrary to the popular myth that Columbus thought he would fall of the Earth if he sailed to far West.

We have no way of knowing which ancient civilizations realized that the Earth was spherical, but it was likely the Phoenicians, those sea-faring traders who roamed the Mediterranean and on to England and the Norse lands.

The formula for this is E = hu, where E is the energy of the radiation, h is a universal constant known as Planck'sconstant, and u is the frequency of the radiation. This proposal-that the energy contained within a light beam is transferred in individual units, or quanta-contradicted a hundred-year-old tradition of considering light energy a manifestation of continuous processes.

The Scientific Method

1. Because there are too many organisms in the Protist Kingdom.

2. Some organisms are way different compared to each other.

Scientists keep detailed records and procedures for a few reason. One of which is because if the experiment or whatever it is they are doing turns out to be successful and needs to be used again, they have every detail to know what went right, if something goes wrong they need to go backwards and know every little detail. This is because the tiniest detail can make a huge difference, it could be the reason some medicine or someting killed somebody for example. If the procedure lead to a great invetion/success, they should be able to do it over again and again. In the future other scientists may want to redo the procedure to see if there is a difference in results and such they need to have the exact original procedure with all details.

this type of scientist is called a marine biologist

He demonstrated that new bacteria appeared in broth only when they were produced by living bacteria. The experiments of Redi and Pasteur helped to convince people that living things do not arise from nonliving material.

Scientists make more mistakes than not. It is part of the business and why they call their work "experiments". As a working scientists you try to keep your basics constant. You control the pH of your solutions, the don't switch suppliers for even basic salts mid-experiment. Most importantly you repeat experiments several times and use statistical analysis to support your conclusions.

The goal of scientist is to have his/her results confirmed by repetition by others. If it isn't reproducible than it isn't believable. But wrong conclusions....

Record your mistake in the results and talk about it in the conclusion/examination of data.

Ernest Rutherford was a brilliant scientist who, among other things, discovered what was inside an atom, putting paid to the previously accepted "plum pudding" model. By setting up a classic experiment involving gold foil and an alpha particle emitter, he noticed that atoms consisted of a dense central region (the nucleus), which possessed a positive charge.
