Answer:

The correct answer will be-

1. Observation-option B.

2. Hypothesis-option A.

3. Experiments- option C.

Explanation:

A scientific method involves various steps to explain a natural phenomenon of nature. It begins with making an observation which leads to asking the scientific question. The researcher does background research and proposes a hypothesis which could be tested through experiments. The experiments could prove or disprove the hypothesis based on the results.

In the given question the observation made is an equal amount of A and T and G and C are observed. It leads to a hypothesis which shows that this could have happened due to the winding of two strands of DNA and the experiments was performed through X-ray diffraction pattern.

Thus, the selected options are the correct answer.

ikadub [295]
<span>This theory is called punctuated equilibrium. In this theory it is explained that there are very long periods of no change at all to a species, yet there are also bursts of evolutionary change interspersed within the time period. The period of remaining the same throughout time (most of the time) is called stasis, and is present within this theory of punctuated equilibrium.</span>

Before the Industrial Revolution (top picture), the bark of the trees was
-BARSIC- [3]
This is an example of evolution through natural selection. The peppered moths started off with a light color scheme when the industrial revolution started, and they had this to blend into the trees. The better the moths could blend in, the less likely they were to be preyed upon. Once the trees changed colors, the light moths were vulnerable. The months that thrived in this change were the darkly colored moths. These moths then bred and spread their dark color pattern to best fit into the new environment.

Why must the formulas of hydrates have the number of water molecules as whole number integers?
Sphinxa [80]

The formula for hydrate indicates the number of water molecules that are attached to each formula unit of the compound. Forexample, nickel (II) sulfate hexahydrate is a green/blue solid that has six water molecules included in the crystal foreach Ni2+and each SO42-ion.Many common minerals are

<h3>What is a hydrate ?</h3>

Any compound containing water in the form of H2O molecules, usually, but not always, with a definite content of water by weight.

  • The best-known hydrates are crystalline solids that lose their fundamental structures upon removal of the bound water.

  • Hydrates are formed when water and light end natural gases come into contact at certain temperature and pressure conditions
