Answer:
The correct answer is option b, that is, the radioactive isotope reacts in the same way as stable isotopes in the chemical reactions in the body.
Explanation:
The carbon-14 atoms, which are created by the cosmic rays associates with oxygen to produce carbon dioxide that plants captivate naturally and comprise it into plant fibers by the process of photosynthesis. Afterward, the plants are consumed by animals and human beings, thus, they take in carbon-14 as well.
The ratio of usual carbon-12 to carbon-14 in the air and in all the living species at a particular period is almost the same. These radioactive isotopes react in a similar manner as stable isotopes in the chemical reactions in the body.
Energy and oreantation its one if not bolth of those
Answer:
The correct answer is Polar structure. See the explanation below, please.
Explanation:
The water molecule is formed by the union of an oxygen atom (O) to two hydrogen atoms (H), forming at an angle of 105 °, having the negative electron density over the O and positive over the H. The water due to its polarity can interact with other equal molecules, by hydrogen bridge (occurs between the atom of H and an electronegative element, in this case the O). It corresponds to a type of dipole-dipole interaction.
Answer:
o Surface Type- Because the atmosphere is heated by the Earth's surface, the surface type plays an important role in the surface air temperature. o Elevation and Aspect- Higher altitude generally has colder temps b/c the air is less dense and there are fewer molecules to absorb incoming solar radiation.
The Earth's surface is actually what heats the air above it.
Explanation:
The energy from the sun is "short-wave", and as such air is transparent to it. The sunlight goes right through the air without heating it at all. This "short-wave" radiation is absorbed by the Earth which then heats up. The heated Earth then emits it's own radiation but it is in the infrared part of the spectrum or "long-wave" radiation. This heat is what warms the atmosphere.
I’d say A yeah I’m pretty sure
