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.
Four new haploid cells are formed once the sister chromatids within the two daughter cells separate, forming four new haploid gametes.
Once a hypothesis is tested and confirmed, and then tested again and confirmed again by many others, it may provide the basis for, or become a part of, a scientific theory.
Answer:
How do nutrients move through an environment? What drives the movement of nutrients?
My answer 6b: Nutrients are often transported across the environment by migrating from the physical environment into living creatures and then being recycled back into the physical environment. For example, an animal could receive nutrition by eating plants. To stay alive, the animal uses the chemical energy gained from the food. When the animal dies, the nutrients in its body return to the soil and are re-absorbed by plants. The transport of nutrients in the ecosystem is driven by nutrient cycles.
