A paradigm shift, as identified by American physicist and philosopher Thomas Kuhn, is a fundamental change in the basic conceptsand experimental practices of a scientific discipline. Kuhn contrasted these shifts, which characterize a scientific revolution, to the activity of normal science, which he described as scientific work done within a prevailing framework (or paradigm). In this context, the word "paradigm" is used in its original meaning, as "example" (Greek:παράδειγμα).
The nature of scientific revolutions has been a question posed by modern philosophy sinceImmanuel Kant used the phrase in the preface to his Critique of Pure Reason (1781), referring to Greek mathematics and Newtonian physics. In the 20th century, new crises in the basic concepts of mathematics, physics, andbiology, revitalized interest in the question among scholars. It was against this active background that Kuhn published his work.
Kuhn presented his notion of a paradigm shift in his influential book The Structure of Scientific Revolutions (1962). As one commentator summarizes:
Kuhn acknowledges having used the term "paradigm" in two different meanings. In the first one, "paradigm" designates what the members of a certain scientific community have in common, that is to say, the whole of techniques, patents and values shared by the members of the community. In the second sense, the paradigm is a single element of a whole, say for instance Newton’s Principia, which, acting as a common model or an example... stands for the explicit rules and thus defines a coherent tradition of investigation. Thus the question is for Kuhn to investigate by means of the paradigm what makes possible the constitution of what he calls "normal science". That is to say, the science which can decide if a certain problem will be considered scientific or not. Normal science does not mean at all a science guided by a coherent system of rules, on the contrary, the rules can be derived from the paradigms, but the paradigms can guide the investigation also in the absence of rules. This is precisely the second meaning of the term "paradigm", which Kuhn considered the most new and profound, though it is in truth the oldest.[1]
The answer would be A. 500g because the candle would not lose mass despite being melted. Melting the candle is only a physical change and not a chemical change resulting in no change in the mass.
Answer:
<em>The correct option is A) O→ orange, o→ black</em>
Explanation:
A dominant allele can be described as the allele which masks the effect of a recessive allele. A recessive allele can be described as the allele whose effect gets suppressed by the dominant allele. A dominant allele is written with a capital letter whereas a recessive allele is referred with a small letter.
As the option A shows capital letter, O, for the dominant orange trait and small letter, o , for the recessive black trait hence, it is the correct option.
The dichotomous key is an important tool to identify the species of living beings, with this tool it was possible to identify the proposed species, however, to understand this question, we need to know that.......

Dichotomous Key for Insects</h3><h3 />
This dichotomous key is a simplification and is used to find the order of most insects. But as in biology there is always someone or something to deny us, there are insects that defy this order 1.
Start by choosing between one of the two alternatives of option number 1 and go to the indicated number:
- - Obvious, membranous wings, sometimes covered with scales or fur: - Wings absent or forewings thick and hiding membranous hindwings: 15
- Wings covered with small scales and proboscis-shaped mouthparts: LEPIDOPTERA
- Wings not covered with scales, usually translucent. Mouthpiece is not a proboscis: 3
- - With a pair of wings: DIPTERA
- With two pairs of wings: 4
- - Long, narrow wings, fringed with fur. Size 5 mm or less: THYSANOPTERA
- Wings not narrow and fringed: 5
- - Abdomen with 2 or 3 long filaments. Small hindwings: EPHEMEROPTERA
- Abdomen with short filaments or none. Full-sized hindwings: 6
- - Forewings clearly longer and with a larger area than the hind wings: - Four forewings as long as, or nearly as long as the hind wings and with a similar or smaller area: 10
- - Wings hairy, opaque, with long palps antennae as long as the body or longer: TRICHOPTERA
- Transparent or translucent wings, hairless, palps short or absent, antennae shorter than the body: 8
- - Tarsus with 5 segments, usually with a wasp or bee face: HYMENOPTERA
- Tarsus with 2 or 3 segments, without a bee or wasp face: 9
- - Sucking mouthpiece, nozzle starting at the back of the head. Small to large: HOMOPTERA
- Chewing mouthpiece, without beak, length 7 mm or less: PSOCOPTERA
- - Head extended ventrally forming beak-shaped structure: MECOPTERA
- Head not extended ventrally: 11 - - Very short antennae with thick fur and large eyes: ODONATA
- Antennas not so short. Moderate to small eyes: 12
- - Hindwings wider than forewings. Cerci present: PLECOPTERA
- Hindwings as wide or almost as wide as forewings.
With this identification key we can taxonomically classify the 10 insects contained in the question, and with that we can discover the species we are studying.
Taxonomy is an important tool to better understand the species of living beings, their species diversity and their role in ecology.

I'm not entirely sure on this one... But I think it's 1. cell division helps animals repair old cells..
