The remains of a Hadrosaur are an example of a fossil typically structures like bones shells and teeth fossilized more often then things like tissues or plant leaves.
The main form is carbon dioxide and methane
Hi there!
<u>Electronegativity</u> is the concept of how likely an atom is to attract the shared molecules in one of these bonds to itself. We know the molecule water is made up of two hydrogens and one oxygen. The electronegativity of hydrogen is 2.2, and oxygen 3.4. An <u>ionic bond</u> needs at least a difference in electronegativity of 1.6. As the difference is less than that, we can say that water is a covalent molecule. This then wipes out choice B, because it is not ionic, and C, as we have seen it is actually covalent.
Now, we can see the difference in electronegativity between oxygen and hydrogen is still 1.2. This means that while it is not at the point for there to be an ionic bond, there is still a difference in attraction, where the electrons will tend to favor the oxygen more and 'hang around it' more. As electrons are <u>negatively charged</u><em><u>,</u></em> this means that the oxygen will gain a slightly negative charge. This then makes the molecule polar, because it now has a charge within the molecule. This means we have our answer, choice D.
In terms of hydrophobic molecules - they tend to be ones without a charge. (If you're interested in this kind of stuff, I'd search hydrophobic up, and possibly also look into hydrogen bonds).
Hope this helps! Feel free to ask me any other questions you have about this specific problem.
The answers include the following:
- Arrow F represents transpiration.
- Matter is conserved through the process in which carbon from carbon dioxide leaves and enters into the atmosphere.
- This process is a recycling of carbon in the carbon cycle because it involves it travelling the atmosphere into organisms in the Earth in a repeated manner.
<h3>
What is Carbon cycle?</h3>
This refers to the biogeochemical cycle in which carbon is reused through different types of mechanisms and actions.
This process involves carbon travelling the atmosphere into organisms in the earth in a repeated fashion through methods such as respiration, transpiration etc which is how recycling works.
This is therefore the reason why it can be regarded as the process which involves matter and conservation and recycling.

its asking for you to check the box if the item is preset in the cell hint: eukaryotic cells have a nucleus so you would say yes in the box. but since prokaryotic cells don't have a nucleus say no in the box
