An example of two molecules that contain carbon is compound methane ( 1 carbon bounded to four hydrogen. ) and Ethane ( two carbon atoms and four hydrogen ). Carbon is able to form so many molecules/compounds because each carbon atom can form four chemical bonds to other atoms and, because of its size, it fits in nicely as part of large molecules. Hope this helps!
Density is mass divided by volume
The correct answer is D. They have two successive sets of teeth including milk teeth and permanent adult teeth
Explanation:
In biology, a diphyodont is an animal that has two different sets of teeth, this often means the animal has a set of baby teeth that are later replaced by permanent teeth, this occurs in most mammals including humans. Additionally, diphyodont differ from other types of animals that have either only one set of teeth (monophyodonts), for example, toothed whales or change their teeth permanently (polyphyodont), for example, crocodiles. Thus, mammals are diphyodont because "they have two successive sets of teeth including milk teeth and permanent adult teeth".
<em>Photosynthesis processes used plants and other autotrophs to capture light energy and use it to power chemical reactions and convert carbon dioxide and water into oxygen and energy-rich carbohydrates such as sugars and starches. </em>
<em>The </em><em>similarities</em><em> and </em><em>differences</em><em> between photosynthesis and cellular respiration:</em>
<em>The Similarities; </em>
- <em>Both involve in production of energy
</em>
- <em>
Both involve the exchange of gases</em>
<em>The Differences: </em>
- <em>Photosynthesis takes put in chloroplast, where as cellular respiration takes put in mitochondria.</em>
- <em>Photosynthesis happen as it were during presence of daylight where as cellular respiration happens all the time.</em>
