<span>The amount of energy at each trophic level decreases as itmoves through an ecosystem. ... An energy pyramid is a model that shows the flow of energy from one trophic, or feeding, levelto the next in an ecosystem. The model is a diagram that compares the energy used by organisms at each trophic level.</span>
The answer is Mutualism because they are both benefiting
Answer:
Homologous features
Explanation:
If two or more species share a unique physical feature, such as a complex bone structure or a body plan, they may all have inherited this feature from a common ancestor. Physical features shared due to evolutionary history (a common ancestor) are said to be homologous.
<span>The correct answer is
posterior pituitary.</span>
ADH (AntiDiuretic Hormone) or Vasopressin is a peptide hormone which is produced in the hypothalamus. ADH is released from vesicles inside the cells of posterior pituitary into the circulation. ADH is released as a response of hyperosmolality of extracellular fluid. It increases the reabsorption of water in kidneys and constricts the blood vessels.
Oxytocin is also peptide hormone produced by the hypothalamus and released by the posterior pituitary. It has a role in sexual reproduction.

The odds are astronomical for a father with AB(IV) to have an O(I) child. The only possible way for this phenomenon to occur is if there was a nondisjunction in the ovogenesis for the 9th chromosome and the father also had a nondisjunction for the same chromosome(A sperm cell with no 9th chromosome fertilized an ovum with two 9 chromosomes).
A person with AB cannot donate to a person with O because the receiver has antibodies(alpha and beta) that bind to the antigens on the AB blood cells, causing death.
