Cohesion: Hydrogen Bonds Make Water Sticky
Explanation:
Cohesion: Hydrogen Bonds Make Water Sticky
In the case of water, hydrogen bonds form between neighboring hydrogen and oxygen atoms of adjacent water molecules. The attraction between individual water molecules creates a bond known as a hydrogen bond.
<span>Answer: a) a series of anatomical traits that distinguish Cro-magnon features from Neandertals.</span>
<span>Neanderthals (Homo neanderthalensis) were first discovered in Germany in 1856 and are believed to emerged between 100,000 and 200,000 years ago. </span>
<span>Significant differences found in the human and </span>Neanderthal includes<span>: 1) their DNA, 2) the brain of a Neanderthal had a raised larynx and was also bigger, and 3) Compared to modern humans, Neanderthals had bigger and muscular body but with shorter legs.</span>
Cro-magnon is<span> the earliest known Western European example of our species who lived 35,000 and 10,000 years ago. They are believed to be actually modern in every anatomical respect. They are much like us.</span>
<span>Neanderthal and Cro-magnon were believed to overlap in Europe for a thousand years but long-term interbreeding was not seen. </span>
Nitrogen is from the atmosphere is converted into nitrates by nitrogen fixing bacteria such as rhizobium which is found in the root nodules of leguminous crops
Answer:
B
Explanation:
Organic chemistry is defined as the study of carbon compounds.
Organic compounds were first thought to be compounds that could only be produced by living organisms. This theory was disproved when scientists synthetically made urea from ammonia in a lab.
Organic compounds are now known as compounds where carbon atoms are covalently bonded to other elements. This could be hydrogen or oxygen (in the case of lipids or carbohydrates) or nitrogen (in the case of amino acids).
