question 9 of 25
the macaroni penguin, shown here, is a flightless bird native to chilly aquatic
ecosystems in the southern hemisphere. which variation would make a
macaroni penguin even better adapted to the land and water in which it lives?
a. smaller feet with less webbing between the toes
b. denser, more waterproof feathers that provide warmth
c. more - brightly colored feathers to attract attention from predators
d. bones that are hollow to reduce weight for easier flight

Explanation:

Penguins live in cold aquatic environments. Denser, waterproof feathers would help them stay warm in water and on land. Smaller feet with less webbing (A) would hinder swimming. Bright feathers (C) attract predators, bad for survival. Hollow bones (D) are for flight, but macaroni penguins are flightless. So B is the best adaptation.

Answer:

B. Denser, more waterproof feathers that provide warmth
