<span>Neils Bohr </span>developed a model of the atom (Bohr model) to explain how the structure of the atom changes when it undergoes energy changes. His major idea was that energy of the atom was quantized (this means that the atom could only have very specific amounts of energy) and the amount of energy in the atom was related to the electrons possession in the atom. In the Bohr model, electrons travel in orbits around the nucleus. The further the electron from the nucleus the more energy it has. Bohr used Planck's quantum concept of E=hv.

Scientists once debated how to classify the red panda. Today, how has analysis of the genome of the red panda provided evidence
skad [1K]

Answer:

According to scientists in some countries, the latest DNA research located the red panda in its own independent family, the ailurids (Ailuridae). Ailurids are themselves part of the large superfamily Musteloidea, which also includes the Mephitidae, Mustelidae and Procyonidae families, but, unlike the giant panda, it is not a bear (Ursidae).

The taxonomic classification of red panda and giant panda has been the subject of debate for many decades, as it has characteristics of both bears and raccoons. However, they are only distantly linked by a common ancestor of the first Tertiary period. Its common ancestor dates back tens of millions of years, with a wide distribution in Eurasia.

Explanation:

Musteloids (Musteloidea) are a carnivorous mammalian superfamily united by distributed characters of the skull and teeth. Musteloids share a common ancestor with pinnipeds, specifically phocids, the family to which seals belong. Musteloids consist of the families Ailuridae (red pandas), Mustelidae (mustelids: weasels), Procyonidae (protionids: raccoons and relatives) and Mephitidae (skunks). In North America, the ursoids and musteloids appear first in the Chadronian (Upper Eocene). In Europe, ursoids and musteloids first appear in the lower Oligocene immediately following the great Stehlin break. The Musteloidea superfamily may not be a monophyletic group. Some or all of the diagnostic characters may have evolved into two or more independent radiations from primitive ursoids such as Amphicynodon.

After a successful launch and return of a rocket, NASA and SpaceX noticed a strange gel like substance on the wing. Under the mi
wariber [46]

nonliving the heat from the hot plate is causing the gel like substance to move it's the same thing with liquid nitrogen how it seems to bounce off the floor it's because liquid nitrogen is super cold and the heat basically excites the electrons in the liquid nitrogen making it bounce off the floor same with the gel like substance the electrons in the gel substance are getting excited by the heat and jumping up and down but the substance itself is not alive

What is this the definition of?<br><br> Reaction that disassembles polymers and absorbs water.
Monica [59]

Answer:

Hydrolysis reactions use water to breakdown polymers into monomers and is the opposite of dehydration synthesis, which forms water when synthesizing a polymer from monomers. Hydrolysis reactions break bonds and release energy.

3. Consider the technology behind each type of
Degger [83]

Answer:

See the answer below

Explanation:

<em>The light microscope uses visible light to produce images of objects on its slide while the electron microscope uses beams of electrons to project the image of specimens.  Color is a property of photons of light, hence, the light microscope is able to produce images of specimens in their natural colors </em>

<em>The areas of the specimen on an electron microscope in which the beams of electron pass through usually appear white while other areas appear black. Hence, the electron microscopes can only produce grayscale images of specimens unless a false color is added to make the images visually appealing.</em>
