[Grade 10] Need science help! (Biology)

Questions:
1) Describe how the frog's circulatory and digestive system are physically connected.

2) Explain why the interaction of the respiratory and circulatory systems is necessary for the frog's survival.

3) Cold-blooded animals, such as frogs, are able to deliver blood to their cells once their bodies warm up. Predict when you think frogs are likely.

It will be greatly appreciated, if someone can answer those​

 

1) Describe how the frog's circulatory and digestive system are physically connected.

They are connected at the alveoli.

2) Explain why the interaction of the respiratory and circulatory systems is necessary for the frog's survival.

Basically, blood cells pick up and carry oxygen from the lungs of the frog to the body's cells.

3) Cold-blooded animals, such as frogs, are able to deliver blood to their cells once their bodies warm up. Predict when you think frogs are likely.

Likely to... What? I'm gonna guess that you meant to put be moving or active... In warm climates/warmer weather, because blood functions slow down in cold environments. This is why you could literally freeze a frog for hundreds of years and defrost them back to life.

RSGP me? <3daswasup

 

^ about the last part. thats possible??
im ignorant

 

1.



daswasup is correct. They are connected at the alveoli in the lungs. The diagram gives an idea of what's going on.


2.

This interaction is necessary to keep blood oxygen levels high.
All cells require oxygen as an electron receiver at the end of ATP synthesis, amongst other things; and that oxygen is supplied by the bloodstream.

 

Thanks for all the answers. Close thread.
