Answer;

Swollen veins


Swollen veins might be a symptom of a person whose vein valves are not functioning properly and are causing fluid it flow away from the heart.

Valves are structures that are found in the circulatory system both in the heart and the veins.

They function to prevent the back flow of blood.

If the valves are not functioning properly it may lead to various effects such as swollen veins due to the back flow of blood which may lead to the pooling of blood in the extremities.

An island has many kinds of birds, no native species of snakes, and few large predators. Brown snakes eat bird eggs. What is the
olganol [36]

Boiga irregularis or brown snake is a slender, climbing snake with a vertical pupil and large eyes, providing it better nocturnal vision. The species has no natural predator. When the brown snake is accidentally released into the island, it will result in local extinction of the majority of the island's native lizard and bird species.

It will also result in cascading ecological influences by eradicating native pollinators, resulting in the corresponding reduction of the native plant species.

Hence, the correct answer will be fewer birds and more snakes.
