What is a possible path for matter to follow in the river ecosystem?
*Oxygen moves from the river's water into a fish by way of the fish's gills. *Water moves from the river into an otter when the otter drinks. *Nutrients move from an insect to a frog when the frog eats the insect.
What type of heterotroph is frog?
A frog is an omnivore
Do frogs have a rib cage?
They have "ribbits, ribbits, ribbits" instead of ribs. Naaah, seriously, we do need ribs (and diaphragm, and intercoastal muscles, among others) to help us breath. Frogs breath quite differently from us: * oxygen can enter through their moist skin (straight into the blood), also * through the nose/mouth, but the mechanics are different, ribs (diaphragm, intercoastal muscles) are not necessary. More about frogs can be found on: http://en.wikipedia.org.wiki/Frog
How does the mouth and its structures adapt a frog to its terrestrial existence?
The mouths tongue is able to extend so stick to its prey, then drag it into the frog's mouth. From there the frog's vomerine teeth trap the prey so it cannot escape, and can then be eaten. By the frog adapting to capture it's prey efficiently, they are able to eat.
Who cloned the first frog in 1952?
The first mammal successfully cloned was Dolly the Sheep in Scotland. She was cloned by Ian Wilmut and Keith Campbell.
Why do frogs only get oxygen through their skin?
The frog gets oxygen through its lungs just as we do. It can also absorb it through the skin and the mouth lining. Overall the surface area of the skin wouldn't be enough to absorb enough oxygen to supply all the cells of the body. However, absorption through the skin is very useful when the frog is under water.
Does the frog's small lungs affect the frog's ability to take in oxygen?
Yes it does, but for a frog this is not a problem as it is cold blooded with a slow metabolism. This means that it does not need much oxygen. Frogs are also able to absorb oxygen through their moist permeable skin.
What are the advantages of such a skin to the frog?
Absorb some oxygen when moist.
How do leech breathe?
They breathe through their body walls. Leeches absorb oxygen through their skin rather than breathing through a nose.
How much oxygen does frog skin usually absorb?
Consisting that there are more than 5,000 species. what one are you on about?
How does a frog transfer oxygen?
Well, a frog breathes either through its nostrils, mouth or its skin (in the water) if that is what you mean. Through the skin, it takes in oxygen alone.
7 Why are blood vessels so close to the frogs sub surface skin?
The frog's skin has many small blood vessels so that oxygen can go through the thin skin, through the fine blood vessels, and into the blood stream, allowing for the frog to breathe more easily.
Define cutaneous respiration of frog?
Unlike mammals who absorb oxygen through the alveolar in their lungs, frogs are able to use their skin as a surface for gas exchange. The capillaries carry oxygen poor blood underneath the skin so that the oxygen in the air or water will be transported into the blood.
How a frog gets the oxygen it needs to survive?
It breathes through its LUNGS !
How can a frog spend hours underwater without refilling its lungs?
Many frogs, although not all, are able to absorb oxygen through their skin and as a result, are able to remain underwater for extended periods.
Why does a frog soak up water through its skin?
Amphibians need wet skin at all times to breathe through the pores on their skin .
How do Bullfrogs get oxygen?
Bull frogs have lungs to get oxygen. When they are tadpoles, they have gills. Frog also can breathe through their skin.https://www.brown.edu/Departments/Engineering/Courses/En123/MuscleExp/Frog%20Respiration.htm
