Answer:
A. Duodenum
Explanation:
Duodenum is the first part of the small intestine which receives bile juice, pancreatic and intestinal digestive juices. The digestive enzymes present in these juices completes the process of digestion.
The lining of the duodenum has numerous finger-like projections called intestinal villi. The villi are specialized to absorb the digested food by providing increased surface area for the process of digestion. Hence, among the given options, the absorption of digested food occurs in duodenum.
They are formed from the different rates of accumulation of super cooled water as the hail storm forms
The double-stranded DNA (Deoxyribonucleic acid) breaks into two separate strands when the temperature is increased, such as in the denaturation step of the PCR (Polymerase Chain Reaction), because the increase in the temperature makes the hydrogen bonds between the nitrogenous bases to break. The double hydrogen bond between the adenine and thymine, and the triple hydrogen bond between the guanine and cytosine breaks apart when heated causing the two DNA strands to fall apart.
Hence, the answer is the breaking of the hydrogen bond between the nitrogenous bases.
The contents of the air in and around the ecosystem should contain a natural balance between certain atoms and molecules. The variants of wildlife also affect the ecosystem as certain animals and insects allow certain plants to grow. Climate affects both the animals and plants in the ecosystem. For example, if there is a moist warm environment, with lots of tall trees and amphibians, we would probably see a jungle-like ecosystem, depending on a bunch of other factors.
Hope this pile of words helps!
