What must a freshwater fish do to maintain its salt balance in freshwater environments group of answer choices?

An alternative set of physiological mechanisms allows freshwater fish to concentrate salts to compensate for their low salinity environment. They produce very dilute, copious urine (up to a third of their body weight a day) to rid themselves of excess water, while conducting active uptake of ions at the gill.

How do marine fish maintain homeostasis?

Saltwater fish maintain homeostasis by excreting excess salt to maintain a balance of water in high saline conditions.

How can these organisms make the transition from freshwater to ocean water and back to freshwater?

Terms in this set (8) How can these organisms make the transition from fresh water to ocean water and back to fresh water? Salmon eggs hatch in fresh water. The fish then migrate to the ocean (a hypertonic solution) and, after several years of feeding and growing, return to fresh water to breed.

How is homeostasis maintained in a fish?

Proper balance of the internal environment (homeostasis) of a fish is in a great part maintained by the excretory system, especially the kidney. The kidney, gills, and skin play an important role in maintaining a fish’s internal environment and checking the effects of osmosis.

How does a freshwater fish maintain homeostasis in a freshwater hypotonic environment?

An example is freshwater fish. The gills actively uptake salt from the environment by the use of mitochondria-rich cells. Water will diffuse into the fish, so it excretes a very hypotonic (dilute) urine to expel all the excess water.

What must a freshwater fish do to maintain its salt balance in freshwater environments?

To combat this, freshwater fish have very efficient kidneys that excrete water quickly. They also reabsorb salt from their urine before it is ejected to minimize losses and actively take salt from their environment using special cells in the gills.

How do fish maintain their salt and water balance?

To maintain their water balance, marine fishes drink large quantities of seawater, retaining most of the water and excreting the salt. Most nitrogenous waste in marine fishes appears to be secreted by the gills as ammonia. Marine fishes can excrete salt by clusters of special cells (chloride cells) in the gills.

What must a freshwater fish do to maintain its salt balance in freshwater environments quizlet?

salt uptake in gills and water excretion in urine; To maintain constant tissue osmolarity in freshwater environments, the osmoregulatory mechanisms of freshwater fish must counteract the water intake at the gills via osmosis and salt loss at the gills via diffusion.

How do fish survive in high salt environments?

Freshwater fish and saltwater fish survive according to how much salinity their body can sustain. To survive, saltwater fishes continually drink lots of water to compensate for water loss caused by osmosis. They filter out excess salt from their bloodstream through their gills and kidneys by urinating.

How do marine animals maintain homeostasis?

Water balance is maintained in these animals via metabolic and dietary water, while incidental ingestion and dietary salt may help maintain electrolyte homeostasis. Unlike most other aquatic mammals, sea otters commonly drink sea water and manatees frequently drink fresh water.

How do saltwater and freshwater fish maintain homeostasis?

Freshwater fish use gills that filter water as they breathe. The bodily fluids remain inside the fish. Saltwater fish, on the other hand, lose a good deal of body fluids into the water through osmosis. Thus the saltwater fish has to consume large amounts of salt water to maintain homeostasis.

What do freshwater fish do to maintain homeostasis?

Freshwater fish are able to maintain homeostasis through osmoregulation and temperature control.

How do fish maintain their body temperature?

Fish don’t sweat to regulate their body temperature but they do have strategies for thermoregulation (www.fishlady.us). Most fish are ectothermic, using their environmental temperature to manage their body temperature, but some fish are endothermic, having the metabolic ability to internally manage temperature.

How do freshwater salmon become saltwater?

As you know, salmon spend most of their life in the open ocean, where they reach sexual maturity, but lay their eggs gravel beds at the upper reaches of (freshwater) streams. When the eggs hatch, the young salmon spend several months migrating downstream to the ocean where they remain for some 3-5 years.

How have freshwater and saltwater fish adapted to deal with osmosis in their respective environments quizlet?

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. Conversely, freshwater fish absorb salt from their surroundings using their gills and their bodies reabsorb salt from their urine.

How might this interesting adaptation limit the habitat that the hagfish can tolerate?

How might this interesting adaptation limit the habitat that the hagfish can tolerate? Hagfish habitat is limited by the salinity of the environment. What role do chloride cells play in osmoregulation of marine fish with bony skeletons? They are involved in excretion of excess salt.

How do freshwater fish maintain a stable environment around their cells?

Freshwater fish maintain the physiological mechanisms that permit them to concentrate salts within their bodies in a salt-deficient environment; marine fish, on the other hand, excrete excess salts in a hypertonic environment. Fish that live in both environments retain both mechanisms.

How do goldfish normally maintain homeostasis?

Freshwater fish are able to maintain homeostasis through osmoregulation and temperature control.

Which example is an activity that a fish most likely uses to maintain homeostasis within its body?

Most fish body temperature’s change with the temperature of the water around them. In order to obtain temperature homeostasis, the fish seek colder or warmer water. They lose metabolic heat through their gills. Warm blooded animals are able to retain a more adjustable constant body temperature.

How water and ion homeostasis are maintained for a freshwater fish and a saltwater fish?

Which example is an activity that a fish most likely uses to maintain homeostasis within its body? Exchanging gases through its gills to regulate oxygen levels. The relative concentration of solute inside and outside a cell can cause water molecules to move across the membrane.

How do freshwater fish deal with their hypotonic environment?

Controlling Osmosis Organisms that live in a hypotonic environment such as freshwater, need a way to prevent their cells from taking in too much water by osmosis. Freshwater and saltwater fish have the ability to adjust to the osmotic pressure in the water around them.

Do freshwater fish live in a hypotonic environment?

Freshwater fish are able to maintain homeostasis through osmoregulation and temperature control.

What does it mean if a fish is hypotonic?

Freshwater fish and saltwater fish survive according to how much salinity their body can sustain. Because freshwater is hypotonic to the fishes living in it, water is continually entering their bodies through their gills, skin, or their mouths when they eat.

How do fish deal with salt?

An alternative set of physiological mechanisms allows freshwater fish to concentrate salts to compensate for their low salinity environment. They produce very dilute, copious urine (up to a third of their body weight a day) to rid themselves of excess water, while conducting active uptake of ions at the gill.
