Answer:
They have a gizzard to grind the food.
Explanation:
Birds cannot chew since they have no teeth. However, the beak allows them to split very large seeds or swallow them directly.
For their digestion they have a stomach where digestion enzymes are released. Also they have a gizzard that is an organ that grinds the food mechanically. This gizzard usually has small stones inside that were previously ingested and that helps to digest the food.
Cytosine pairs with Guanine
Adenine and Thymine are pairs also
Hope this helps :)
False it is just the opposite if the gfr levels are increased it leads to reduced urine production.
