Question

1. Select all of the animal traits that could have been shaped by pollination co-evolution (mark all that apply).

1. Proboscis length of insect
2. Shape of bird beak
3. Length of bat tounge
4. Fur color of a bat
5. Feather length of birds

Answer 1

ANSWER- OPTION 1 2 3 ARE CORRECT

1) The length of proboscis is a pollination co evolution. with passage of the time,if the nectar or pollen is not available to the insect because of size indifference,then proboscis's length varies with time and adjust with co evolution.

2) shape of bird beak vaires with respect to nectar of flower. the deeper the nectar,the longer and sharp will be the beak and this is an example of co evolution of pollination.

3) the tongue of the bat varies and co evolved according to the need of the nectar availablity.

4) fur color is not one of the pollination co evolution,as by now the bat color doesn't change by now for last so Many centuries.

5) the feather length of birds is not considered as co evolution of pollination, as feathers doesn't play any role in nectar gathering.

hence, option 1 2 3 are legitimate, while other options are not apt.
