Scientists have observed that in the Antarctic ecosystem Adélie and Chinstrap penguin populations have decreased in the past 40

years by about half. However, Gentoo penguin populations have remained steady and are possibly increasing. Increasing ocean temperatures in the Antarctic is resulting in less sea ice and less krill because krill depend on sea ice.
Which statement, if true, BEST explains why Gentoo penguins have a survival advantage in the changing Antarctic environment?

A.
Adult Gentoo penguins average about 0.5 kilograms more in weight than adult Adélie and Chinstrap penguins.

B.
Leopard seals prey heavily upon juvenile penguins.

C.
Gentoo penguins eat more types of prey than either Adélie or Chinstrap penguins.

D.
Penguins spend a large amount of their energy on keeping warm during harsh winters with very low temperatures.

The oxygen that is released as o2 during photosynthesis came from _____________ molecules.
AlexFokin [52]

Answer:

Water (H2O)

Explanation:

Light reactions of photosynthesis release oxygen as a by-product. In the presence of sunlight, photolysis of water molecules occurs. Splitting of two water molecules obtains four electrons, four protons, and molecular oxygen. The oxygen-evolving complex, also called the water-splitting complex is associated with photosystem II (PS II). Splitting of water occurs in the oxygen evolving complex and the released electrons are passed one at a time to the reaction center of PS II. Therefore, a water molecule serves as a source of oxygen released during photosynthesis.

Explain the process of homeostasis through BOTH negative and positive feedback
kotegsom [21]
Homeostasis is maintained by negative feedback loops within the organism. In contrast, positive feedback loops push the organism further out of homeostasis, but may be necessary for life to occur. Homeostasis is controlled by the nervous and endocrine systems in mammals.
