In the deep waters of the ocean, coral reefs are found in abundance. Algae live within these coral reefs, producing pigments tha

t give corals their color and providing nutrients that corals need to survive. In return, corals offer shelter to the algae. So, coral and algae share a 1.)______ association.
A. mutualistic
B. commensal
C. parasitic.

Climate change has led to increasing ocean temperatures, which can cause corals to expel the algae living inside of them. This phenomenon is known as coral bleaching because it causes corals to lose the pigments produced by the algae. Coral bleaching will lead to 2.)________.
A. a decrease in number of corals.
B. an increase in the number of corals.
C. an increase in the number of algae dependent on corals.

Use the principles of diffusion to explain why oxygen molecules in the tissues of the lung go into the blood
Keith_Richards [23]

Answer:

Oxygen molecules in the tissues of the lung diffuse into the blood because the concentration of oxygen in the lung's tissues is more than the concentration of oxygen in the blood.

Explanation:

Diffusion is the movement of molecules from the region of higher concentration of the molecule to the region of lower concentration of the same molecule. Molecules in diffusion move <em>downward the concentration</em> <em>gradient</em> created by difference in concentration between two regions until an <em>equilibrium (equal concentration in the two regions)</em> is established.

Oxygen molecules diffuse into the tissues of the lung when an organism breathes-in during the process of breathing. The molecules in the now oxygen-rich tissues eventually start diffusing into the blood in the lung because the blood passing through the lung is always de-oxygenated or has lower oxygen concentration compared to the tissues of the lung.

Oxygenated blood moves into the heart, pumps round the body by the heart, gets depleted of oxygen and eventually find its way back to the lung where the process is repeated.

Diffusion of oxygen from the tissues of the lung into the blood will keep happening as long as oxygen keeps getting dissolved into the lung's tissues and an equilibrium is yet to be established between the tissues and the blood.

Studies have shown that there is a relationship between the type and location of boundaries and the distribution and depth of ea
Andre45 [30]

Answer:

The correct answer is B. <em>Philippine plate converging with the Pacific plate, forming Mariana Islands in the Pacific Ocean</em>

Explanation:

When two oceanic plates collide, it occurs oceanic convergence. The thicker and older plate subduces under the other plate, and at this point, it starts the volcanic activity. As the thicker plate descends, it is heated and melted and its materials are incorporated into the mantle. The fast subduction originates magma that ascends to the surface by crevices. This makes place to the formation of grouped volcanic islands, the island arches. Subduction zones coincide with deep-sea trenches or depressions in the ocean bed. The volcanic islands are arranged in a circumference arch shape, which is bordered by a fossa. Most of these are located in the western Pacific, where the pacific crust is older and thicker, and hence it submerges easier in the mantle.

The Mariana Islands in the Pacific Ocean are examples of these volcanic islands.
