A niche affects biodiversity because of the special role the organism takes. For example a bluebird might only like to eat brown beetles.

Amphitrichous....they have a single flagellum from both ends.
Answer:
The correct answer would be D.Alveolar sacs are surrounded by thin capillaries where gases can be exchanged.
Alveoli are tiny sacs which form the site of gas exchange in the lungs.
The features of alveoli which help in gas exchange are:
- They increase the surface area in the lungs thus, more space is available for gas exchange.
- They have very thin walls, as thin as the thickness of a single cell only.
- They are surrounded by a bunch of thin capillaries which exchange gases with alveoli.
The actual genetic makeup of an individual is its genotype.
