Answer:
A. Gas is added to the bladder as the fish's depth increases.
Explanation:
The swim bladder is a gas-filled organ localized in the dorsal region of Osteichthyes (bony fish) that allows them to regulate buoyancy, thus maintaining water depth without swimming. Since the swim bladder localizes in the dorsal region, it also functions as a stabilizing organ. This organ is composed of two sacs whose walls contract and expand in response to water pressure. The swim bladder contains an oval window that enables to adjust buoyancy in order to maintain a constant depth, or to ascend or descend in a wide range of water depths.

Egg.

<u>Less reproductive </u><u>isolation </u><u>among populations that share similar </u><u>habitats</u><u>.</u>
What is habitat reproductive isolation?
- Habitat isolation is the term for when populations of a species move to a new habitat and settle in an area where they no longer overlap with other populations of the same species.
- When reproduction with the parent species stops, a new group emerges that is genetically and reproductively independent.
What factors affect reproductive isolation?
- The members of different species will be reproductively isolated by any factor that prevents potentially viable individuals from coming together.
- Different habitats, physical barriers, and a variation in the timing of sexual development or flowering are examples of the different types of barriers that can result in isolation.
