The weakest bonds in a double-stranded molecule of deoxyribonucleic acid exist between the WHAT?
The weakest bonds in a double-stranded molecule of deoxyribonucleic acid exist between the nitrogenous bases of the two strands. These bonds are hydrogen bonds, which form between specific complementary base pairs (adenine with thymine, and guanine with cytosine).
Where is the DNA found?
The strong bonds between the DNA chains are the hydrogen bonds (H-bonds). The H-bonds exist between the base pairs. 2 H-bonds exist between Adenine and Thymine and only 3 H-bonds exist between Guanine and Cytosine. This means that A-T bonds are stronger than C-G, this difference arises purely because of slight chemical differences in the bases.Within the chains the strong bonds are covalent. These covalent bonds are found between the sugar group of one nucleotide and the phosphate group of another.
Is there scientific proof that vampires exist?
No, because vampires do not exist; they are fictional characters.
Adaptations result from interactions between organisms and their .?
Environment..., also Ecosystem..., as long as we permit it to exist.

Between what periods did both Neanderthals and Cro-Magnons co-exist?

What periods did neanderthals and cro-magnons co-exist?
50,000 to 30,000 years ago.
What periods did neanderthals and cro magnons co exist?
50,000 years to 30,000 years ago.
How long ago did man exist?
AnswerCro-Magnons arrived in Europe about 35,000 years ago and lived in Europe about the same time as the Neanderthals, but were physically quite different from Neanderthals. Some see them as virtually indistuinguishable from modern humans.
When did Neanderthal men exist?
Neanderthals are alleged to have existed during a time span anywhere between 600,000 to 24,000 years ago.
When did neanderthals cease to exist?
They died out about 27,000 years ago.
Do the cro-magnons eat honey?
Probably. Most primitive cultures that still exist in the world eat honey.
Did man and mammoths exist?
Mammoths existed during the ice age when Neanderthals and homosapiens both existed. So yea.
Did Neanderthals and humans co exist?
Of course they did! Scientist have found fossils that are dated to about 600,000-350,000 years ago.For that matter, "neanderthals" were human, Homo sapiens neanderthalensis. They are considered a subspecies... about as closely related to modern humans as dogs are to wolves, for example.
What is the difference between have someone and had someone?
If you have someone, the relationship exists at the current time. If you had someone, the relationship used to exist but no longer does. (If you have had someone, the relationship existed for a period or for periods in the past. If you had had someone, the relationship existed for a period or for periods in the past but ended at some point in the past.)
Why do you need to study about prehistory?
You don't need to but you can learn about how similar we were to the prehistoric people, how similar their lives were to ours and how they lived and died, how they had two types of homo sapiens. There were the Cro-Magnon and Neanderthals. Cro-magnons were the smarter humans of the two and the Neanderthals no longer exist because they couldn't figure out the steps to live longer.Studying prehistory now will help to understand today the changes that have happen. It may predict the future.
What are two names for rows in the periodic table?
Periods and the vertical columns are groups
