What submersible craft recovered the hydrogen bomb that fell into Mediterranean Sea during the Palomares hydrogen bomb incident?
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.
Which of the following organisms live near the surface of aquatic biomes because it needs sunlight to survive?
They are what is known as primary producers of the ocean—the organisms that form the base of the food chain. Because they need light phytoplankton live near the surface where enough sunlight can penetrate to power photosynthesis.
Which of the following phrases describes a typical river mouth?
The following phrase describes a typical river mouth: decreased vegetation and lower oxygen levels.
What types of organisms may we find in an aquatic biome?
- Fish – Sharks swordfish tuna clown fish grouper stingray flatfish eels rockfish seahorse sunfish mola and gars.
- Marine mammals – Blue whales seals walruses dolphins manatees and otters.
- Mollusks – Octopus cuttlefish clams conch squids oysters slugs and snails.
Does temperatures in ponds and lakes vary by season?
Temperatures in ponds and lakes vary by season. Organisms that live in freshwater and marine biomes have developed unique adaptations that aid in their survival. … Organisms that live in freshwater and marine biomes have developed unique adaptations that aid in their survival.
What are the two types of aquatic biomes?
Which of the following organisms is responsible for photosynthesis in aquatic biomes?
Algae are a diverse group of aquatic organisms that have the ability to conduct photosynthesis. Certain algae are familiar to most people for instance seaweeds (such as kelp or phytoplankton) pond scum or the algal blooms in lakes.
How have freshwater and saltwater fish adapted to deal with osmosis and their respective environments?
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.
Which of the following adaptations is most likely not found in organisms of the savanna?
thick fur. Thick fur is an adaptation most likely not found in organisms of the savanna.
Is it true that unlike lakes the ocean is separated into zones?
Terms in this set (10)
Temperatures in ponds and lakes vary by season. … Unlike lakes the ocean is separated into zones. False. Organisms that live in freshwater and marine biomes have developed unique adaptations that aid in their survival.
Which of the following is a way humans have impacted the rainforests but not the tundra?
Which of the following is a way humans have impacted the rainforests but not the tundra? … Overgrazing erosion and radioactive pollution are the result of human impact on the tundra biome while logging agriculture and construction are of greater concern in the rainforests.
Are freshwater and marine biomes are evenly distributed on Earth?
Freshwater and marine biomes are evenly distributed on Earth. Freshwater biomes are a vital source of drinking water. Freshwater biomes supply a greater portion of Earth’s oxygen than marine biomes. Marine biomes include streams rivers ponds and lakes.
How do humans use the aquatic biome?
Humans rely on freshwater biomes to provide aquatic resources for drinking water crop irrigation sanitation and industry. These various roles and human benefits are referred to as ecosystem services.
How do the properties of water affect aquatic ecosystems?
Oxygen content and water flow rates affect the oxygen intake and food received by animals. Changes in acidity can damage marine life and marine animals and plants are often adapted to particular temperatures salinities and depths. When we change any of these factors we impact aquatic ecosystems.
How do humans impact marine ecosystems?
How do seasons affect aquatic ecosystems?
Changes in seasonal patterns of precipitation and runoff will alter hydrologic characteristics of aquatic systems affecting species composition and ecosystem productivity. … Changes in the seasonal timing of snowmelt will alter stream flows potentially interfering with the reproduction of many aquatic species.
How does the water level in rivers and other water bodies change with the change of seasons?
Discuss. Answer : In the summer season the water level of the water bodies such as river pond or stream decreases due to the evaporation of water. In the rainy season the water level of the water bodies rises. The water of the ponds freezes in the winter in places where the climatic conditions are very cold.
How do seasons affect aquatic life?
Why is the aquatic biome important?
The aquatic biome is the largest of all the world’s biomes—it occupies about 75 percent of the Earth’s surface area. The aquatic biome provides a vast array of habitats that in turn support a staggering diversity of species. The first life on our planet evolved in ancient waters about 3.5 billion years ago.
What are the four main factors that affect aquatic ecosystems?
What are the four main factors that affect aquatic ecosystems? Water’s depth temperature amount of dissolved nutrients and flow. What does the depth of the water determine? What distinguishes the photic zone from the aphotic zone in an aquatic ecosystem?
What factors influence organisms living in aquatic biomes?
Abiotic factors that influence aquatic biomes include light availability depth stratification temperature currents and tides.
What is the importance of photosynthesis in ocean?
Phytoplankton such as algae are the plants that make photosynthesis happen in the ocean. These tiny plants live on the surface of the water where they collect their energy from the sun and use it along with nutrients in the water to grow and feed ocean life.
How does the coastal ocean zone compare with the open ocean zone?
How do humans benefit from photosynthesis?
Food is the source of energy and is also needed to provide nutrients. Since human beings cannot produce their own food they are dependent on plants carrying out photosynthesis for food. Equally importantly photosynthesis is the source of oxygen and also removes carbon dioxide from our atmosphere.
How are saltwater fish adapted to their saltwater surroundings?
How are saltwater fish adapted to their saltwater surroundings? They absorb water through their skin. They excrete a small volume of very salty urine.
What happens when you place a saltwater organism in a freshwater environment explain your answer in terms of osmosis and osmotic conditions?
When water moves into a cell by osmosis osmotic pressure may build up inside the cell. … For example if a saltwater fish (whose cells are isotonic with seawater) is placed in freshwater its cells will take on excess water lyse and the fish will die.
How do saltwater fish get water?
What most likely determines the type of animals that live in a biome?
Biomes are characterized by their climate which determines the particular plants found there. The climate and the plants in a biome determine what animals live there. This article addresses the climate and biodiversity of one of Earth’s most diverse and iconic biomes: the tropical rainforest.
Which of the following adaptations would you expect to find in an animal in the Alpine biome?
Alpine animals adapt to the cold by hibernating migrating to warmer areas or insulating their bodies with layers of fat and fur. Their bodies tend to have shorter legs tails and ears in order to reduce heat loss.
