What discovery did Alvin make quizlet?
What important discovery did researchers aboard the Alvin make? Researchers aboard Alvin discovered the presence of hydrothermal vents on the ocean floor.
Is it true that unlike lakes the ocean is separated into zones?
Unlike lakes, the ocean is separated into zones. Organisms that live in freshwater and marine biomes have developed unique adaptations that aid in their survival.
Which of the following adaptations would be the most beneficial to wading birds?
Which of the following adaptations would be the most beneficial to wading birds? Saltwater fish constantly drink water but still excrete concentrated urine to compensate for the water loss. They also have gills to help excrete excess salts.
What are the two types of aquatic biomes?
The aquatic biome is the largest of all the biomes, covering about 75 percent of Earth's surface. This biome is usually divided into two categories: freshwater and marine.
What submersible craft recovered the hydrogen bomb that fell into the Mediterranean Sea during the Palomares hydrogen bomb incident?
It was not until Mar. 17, 1966—exactly 50 years ago—that the missing hydrogen bomb was finally recovered, 2,500 ft. underwater off the coast near Palomares, by a submarine nicknamed Alvin, which was kitted out with underwater cameras and a claw capable of lifting objects from the seabed.
What discovery did Alvin make?
What discovery was made by Alvin brainly? Answer: Researchers aboard Alvin discovered the presence of hydrothermal vents on the ocean floor.
How have freshwater and saltwater fish adapted to deal with osmosis in their respective environments?
Water for Replacement Salt water fish are perfectly adapted to their salty environment and need osmosis to live. The replacement fluid taken on to replace the lost water is desalinated by a process known as diffusion. Diffusion allows fish to live in a state of constant osmosis.
How many oceans are in the world?
Historically, there are four named oceans: the Atlantic, Pacific, Indian, and Arctic. However, most countries – including the United States – now recognize the Southern (Antarctic) as the fifth ocean. The Pacific, Atlantic, and Indian are the most commonly known.
How did variations in bird beak types affect survival of the birds?
Birds that are a part of the same species have different characteristics to help them survive. The different shaped beaks picked up certain types of food better than others. This is the result in physical characteristics in the same species working to give the birds an advantage in their environment.
How are birds beaks adapted to their environment?
Varieties of beak shapes and sizes are an adaptation for the different types of foods that birds eat. In general, thick, strong conical beaks are great at breaking tough seeds, and are found on seed-eating birds such as cardinals, finches, and sparrows.
Which aquatic biome forms where freshwater streams or rivers merge with the ocean?
Estuaries. Estuaries are areas where freshwater streams or rivers merge with the ocean. This mixing of waters with such different salt concentrations creates a very interesting and unique ecosystem.
What is Ecology aquatic biomes?
The aquatic biome includes the habitats around the world that are dominated by water—from tropical reefs to brackish mangroves, to Arctic lakes. The aquatic biome is the largest of all the world's biomes—it occupies about 75 percent of the Earth's surface area.
Did the hydrogen bomb work in Lost?
The bomb never went off. Juliet was a candidate, and therefore couldn't kill herself or set off the bomb. The bomb was left at the site, and when Desmond turned the key he actually detonated Jughead. The "incident" would have been tapping into the electromagnetic field, not blowing up the bomb.
When did Alvin find the Titanic?
1986 Most famously, Alvin was involved in the exploration of the wreckage of RMS Titanic in 1986.
How much of the ocean floor can scientists explore using robots like Jason?
Advantages. With a depth rating of 6,500 meters (4 miles) Jason can reach more than 99% of the world's sea floor – more than any other U.S. academic research vessel.
How do the cells in a fish react when it moves from saltwater to freshwater apex?
A fish that lives in salt water will have somewhat salty water inside itself. Put it in the freshwater, and the freshwater will, through osmosis, enter the fish, causing its cells to swell, and the fish will die.
How do saltwater and freshwater fish maintain water an electrolyte balance?

Why is the ocean blue?
The ocean is blue because water absorbs colors in the red part of the light spectrum. Like a filter, this leaves behind colors in the blue part of the light spectrum for us to see. The ocean may also take on green, red, or other hues as light bounces off of floating sediments and particles in the water.
What is Antarctica ocean?
Southern Ocean, also called Antarctic Ocean, body of salt water covering approximately one-sixteenth of Earth's total ocean area. The Southern Ocean is made up of the portions of the world ocean south of the Pacific, Atlantic, and Indian oceans and their tributary seas surrounding Antarctica below 60° S.
What conclusion did Darwin draw when he observed these different finches with different beak types?
Darwin proposed that natural selection had shaped the beaks of different bird populations as they became adapted to eat different foods.
How does the shape of a bird’s beak affect its ability to gather different types of food?
If the food source remains the same, the number of birds with the spoon shaped beak will increase while the number of birds with chop sticks, fork, and tweezers shaped beaks will decrease. The birds with chop sticks and tweezers shaped beaks may disappear completely do to their inability to adequately gather food.
What are the function of a beak?
A beak is used for eating, preening, manipulating objects, killing prey, fighting, probing for food, courtship, and feeding young.
What are beaks used for?
A bird beak is the most important resource it has, and every species has one solely designed for survival. Birds use beaks for just about everything: building nests, feeding their young, cleaning their feathers, defending themselves and eating (of course).
What is a freshwater river biome?
A freshwater biome is a large community of flora and fauna (plants and animals) that live in water bodies with low salt content, usually less than 1%. Examples of freshwater biomes include lakes, ponds, streams, rivers and even some wetlands. Freshwater biomes differ from marine biomes.
When a river meets the sea the two main properties of water that are affected are?
Bodies of water form layers based on differences in density, usually affected most by temperature and salinity. As fresh water from rivers enters an estuary it mixes with saltwater from the sea. What happens to the two different densities of water when they meet? Water will become more dense as its salinity increases.
What characterizes an aquatic biome?
Aquatic biomes are distinguished by the availability of sunlight and the concentration of dissolved oxygen and nutrients in the water. The photic zone extends to a maximum depth of 200 meters, while the aphotic zone is deeper than 200 meters. Aquatic biomes in the ocean are called marine biomes.
What are the characteristics of aquatic habitat?
The main aquatic habitat characteristics, fall into five groups: (a) flow regime, (b) physical habitat structure, (c) chemical variables (water quality), (d) energy (food) sources, and (e) biotic interactions, (Yoder, 1989).
How did the bomb get on the island in Lost?
After a brief shootout ending in a standoff, Jack dropped the bomb into the pit after the drill hit a pocket of energy, and, with the rest of his friends, awaited their fate. However, nothing happened because the bomb failed to detonate.
What happens to Juliet on Lost?
Down the shaft, she noticed the bomb, and in a desperate attempt to save everyone's lives, she detonated it. The explosion sent the survivors to 2007, where Sawyer tried to save her, but was unsuccessful, and she died in his arms.
