- As human activities put more and more carbon dioxide (CO2) into the air, the ocean takes up more CO2 and becomes increasingly acidic. Increased ocean acidity makes it more difficult for marine animals to produce their calcium-rich hard parts. List three types of invertebrates that are likely to be adversely affected by an increase in ocean acidity.Calcium carbonate is used by corals, shelled organisms, and a variety of other marine creatures to construct tissue components. What is the impact of climate change on their ability to construct those components? Temperature increases have diminished available calcium ions in marine habitats Hydrogen ions have increased acidity and will bind to carbonate ions decreasing avialblity to build calcium carbonate shells Hydrogen ions increase basicity of marine waters and induce dissolution of calcium carbonate structures Ocean warming is causing reactions to speed up and shells therefore are thinner and weaker Shelled organism are a product of founder effectMost marine invertebrates are osmotic conformers. How does their body fluid differ from that of sharks and rays, which are also in near osmotic equilibrium with their environment?
- Explain the challenges that insects have to overcome to maintain ion and water balance. Describe the structures used by insects that help them do this.A rise in atmospheric carbon dioxide increases ocean acidity, making it harder for animals to build calcium carbonate parts. List some invertebrate animals that increased ocean acidity could harm in this waySwim bladders in fish and lungs in terrestrial animals have a common evolutionary origin, but have evolved to perform different functions. What is the primary function of swim bladders in fish? They serve as buoyancy control organs. They filter toxins from the water. They allow fish to absorb most of their oxygen. They help in the digestion of food.
- Clown fish are often found swimming within the tentacles of sea anemone whereas other fish avoid them at almost all cost. Which statement below is the best explanation for this observation? The spicules of the sea anemone cannot penetrate a slime layer surrounding a clown fish but other fish do that have that neutralizing slime layer. Clown fish are good at maneuvering between the spines of the sea anemone and use them for camouflage. Clown fish are attracted to the cnidocytes of the sea anemone as their source of food. Clown fish are immune to the sting of the nematocyst of the sea anemone but other fish are not.4) Animals that undergo ecdysis, or molting, include nematodes and arthropods. Why do these animals molt? Group of answer choices shedding the exoskeleton allows the animal to move faster to escape predators the exoskeleton prevents them from obtaining oxygen their outer covering is made of a non-living substance shedding the exoskeleton makes the animal smaller, which makes it easier for the animal to hide from predators in crevicesHydrogen bonding helps salamanders cling to different surfaces. Which of the following surfaces would a salamander have trouble sticking to? Oa polar surface a nonpolar surface none of the above a damp surface
- There are many ways that animals can maintain homeostasis. Osmoregulators are those that; Use energy to maintain a salt balance different from their environment Adapt their body to have the same salt concentration as their environment Have long limbs to absorb heat Are entirely terrestrial animalsBarnacles are crustaceans that live in the ocean. Barnacle larvae are motile and secrete a sticky substance that allows them to attach to a suitable substrate. As they mature into sedentary adults, they secrete layers of calcium carbonate that serve as a protective covering. Some barnacles have been known to attach to the sides of whales. This benefits the barnacles in that they are constantly transported to locations with new sources of food. The whales neither benefit nor are harmed by the presence of barnacles. Barnacles follow r selection strategies. The calcium carbonate covering that protects barnacles is an adaptation that probably evolved as a result of what type of pressure? a) Density independent b) Predation c) Biotic d) Facultative symbiosisBarnacles are crustaceans that live in the ocean. Barnacle larvae are motile and secrete a sticky substance that allows them to attach to a suitable substrate. As they mature into sedentary adults, they secrete layers of calcium carbonate that serve as a protective covering. Some barnacles have been known to attach to the sides of whales. This benefits the barnacles in that they are constantly transported to locations with new sources of food. The whales neither benefit nor are harmed by the presence of barnacles. Barnacles follow r selection strategies. Which of the following is not accurate of barnacles based on this information? a) High fecundity b) Extensive parental care c) Early maturation d) Short lifespan
