Answer:
The cross between plants with genotype Yyrr and yyRr and gametes that are proces by them are:
gametes that the Yyrr individual can produce - Yr or yr.
The YyRr individual can produce - YR, Yr, yR, or yr.
The possible genotypes are shown in the punnet square.
For a pea to be yellow and wrinkled, it would have the genotype YYrr, or Yyrr (as yellow is dominant (Y) and wrinkled is recessive (r)).
Therefore, we count the number of those genotypes of the total genotypes we get are shown in punnet square..

Answer: b. birds have beak adapted to break open hard shells.
Birds in the rain forests are adapted to perform different functions. It helps birds to capture their food, groom their features, defend their territories and attack predators. The shape of the beak defines a particular ecological niche of a particular bird. The shape of the beak are specially adapted to eat foods such as seeds, fruits, insects. The beaks becomes hard and pointed in order to break open pods, seeds, fruits available as food source in rain forests. Therefore, adaptation in beak allows birds to feed different types of food and allows them to switch to different sources of food if one source becomes scare in the rain forests.
