Readme [11.4K]

Answer:

3/8

Explanation:

Martha has a widow's peak (dominant trait) and attached earlobes (recessive trait).

Martha's dad had a straight hairline (ww) and unattached earlobes (Ee, because she has the recessive alleles ee and both parents give us one allele).

This tells you that martha has a mother with at least one of both alleles dominant for widow peak and at least one recesive allele of attached earlobes

How do birds digest their food in the absence of teeth?
vodka [1.7K]

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.
