The answer is c as the population had failed to survive
Out of the choices given, the conclusion that can be made is that in both cases, societies were brought into contact through trade. The cultural exchanges that went along with that trade enriched those societies. The correct answer is C.
The kind of lipid that forms when a glycerol combines with fatty acids through dehydration synthesis is the trigylceride. It is also known as a triacylglycerol. It is compound that is formed from a glycerol molecule and three molecules of fatty acid. It is synthesized by the reaction dehydration synthesis wherein water is the by-product of the process. The -OH from the functional group of glycerol are detached and the fatty acids would attach to it forming the triglyceride. A dehydration synthesis involves the combining of smaller molecules to be able to form a larger molecule and along with it water molecules are being released. It is also known as a condensation reaction.
I believe all of these answers are correct. <span>Proteins
play a key role in cell differentiation. The external environment,
specifically temperature, during the development of turtles and some
other reptiles helps to determine the sex of hatching offspring
Different transcription factors are associated with the differentiation
of stem cells into bone, muscle,
and nerve cells. Transcription
factors bind to regulatory regions of a gene and affect their
expression. The amount of available light or day length helps to
determine the
patterns of gene expression
that lead to flowering in
some plants.
