The given blank can be filled with liver.
The huge surface area of the small intestine helps in absorption of nutrients. The water-soluble nutrients and small fats enter the bloodstream directly. The inner surface of the small intestine comprises hundreds of folds of compositions known as villi. Within the villi, there are numerous microscopic projections known as microvilli.
The microvilli substantially enhance the surface area of the small intestine that upsurges the rate of absorption of nutrients. Upon entering the bloodstream the water-soluble nutrients are directed towards the liver prior to being transported to the cells.
Answer:
The replication (exact duplication) of DNA begins with the unwinding of the double helix.
Explanation:
DNA replication is the first step of the central dogma of molecular biology which deals with the formation of 2 daughter DNA molecules from a single parental DNA.
The replcation begin with unwinding of DNA double helix by the breakage of hydrogen bonds between the complementary base pairs resulting in the formation of replication fork.
This incident occur by the catalytic activity of Helicase or dna B protein.

Answer:
D. The energy flow is not dependent on any members of the ecosystem
Explanation:
The energy flow in an ecosystem is not dependent on any member of the ecosystem. It is the flow of energy through the food chain, energy is passed from members in one trophic level to members in another or the next trophic level. The flow of energy in an ecosystem is important because it helps in maintaining balance in ecology.
