11. Countercurrent exchange in the legs of geese

Biology
1 answer:
Shkiper50 [21]3 years ago
5 0

Answer:

Reduces heat lost to the water

Explanation:

In some birds such as the geese, to reduce the amount of energy cost when regulation their temperature, some morphological and behavioural has been used to maintain the rate of heat gain and loss. For uninsulated parts of the birds's body such as the legs, there is the presence to countercurrent head exchange between wherein the arteries and veins in the legs lie in close contact with each other in other to retain heat as these uninstalled regions are potential areas of heat loss since they are uninsulated unlike insulated parts (parts covered with feathers). Constriction of the arteries and veins will ensure blood flow to the feet of the geese at a low temperature.

Help please describe how the biotic factors taiga differ from those in the rainforest
grandymaker [24]

Answer: biotic factors include plants and animals. So, the rainforest animals are more adapted to warmer weather meaning they have less fur and are built for warmer weather. The plants in a rainforest need lots of water to survive as well as carbon dioxide so they have large, wide leaves.

In a Taiga biome, the animals have more fur and adaptations to help them to survive in colder weather. The plants primarily consist of fir and pine trees, which have waxy, needle-like leaves to retain water as well. The trees also dont lose their leaves in the winter.
