Uracil & Thymine
Explanation:
Uracil, a nucleic acid nitrogenous base, is only found in RNA and does not occur in DNA. On DNA its place is taken by Thymine base. Marking Uracil with a radioactive or fluorescent tag will ensure that only RNA is traced while tagging Thymine ensures that only DNA is traced.
Thymine is found in DNA because it is more stable than Uracil hence it provides an evolutionary advantage in its use to store cell information.

It is <u>true </u>that i<span>n operant conditioning, many complex behaviors are learned through shaping.
This means that you learn many new things through consequences that you experience. So, for example, when you're a kid, you are constantly being told not to touch a hot stove. But given that you are small and inquisitive, you still touch it and burn your hand. After that, you learn that touching something hot is going to hurt you, so you learn not to do it through a consequence.</span>
Answer:
The correct answer is A. a rotating cloud of dust and gas.
Explanation:
Nebulae are regions of the interstellar medium (clouds) made up of gases (mainly hydrogen and helium) and dust. In other words, nebulae are concentrations of gas in which we find hydrogen, helium and stardust in greater quantities. They are structures that are actually very important for the universe, this because inside it is the place where stars are born, which arise due to the condensation and aggregation of matter. The nebular theory states that the Solar System reached the form current from a solar nebula (a gas cloud), more than 4.5 billion years ago. The large cloud of molecular gas was affected by a certain phenomenon that would have taken place in the vicinity. Like the explosion of a supernova or the passage of a star that would produce a strong gravitational impact. The result of this event made the matter agglomerate in different places. The high concentration of matter caused the nebula to collapse. Becoming a protostar, (bodies whose characteristic is to be surrounded by clouds and contain preplanetary matter inside), that is, gaseous matter in the outermost part and solid inward. At the core of this structure, the temperature is so dominant that nuclear reactions take place to compensate for the gravitational force. This leads to a hydrostatic equilibrium and the formation of a fundamental star: the Sun. The rest of the mass flattened, forming a protoplanetary disk where the protoplanets were being formed, which would evolve to become the current planets, their satellites and the others bodies of the solar system.
If you can generate a strong enough static charge, and construct a glove to hold the charge, like a capacitor and slowly pour water on the glove. the positive hydrogen molecules in the water will attract to the static charge. and will become suspended.
This is just a theory so if you do try this please. tell me how it goes.
Explanation:
Weather is what conditions of the atmosphere are over a short period of time, and climate is how the atmosphere "behaves" over relatively long periods of time.
