1/2 bc it’s independent. It isn’t based on the gender of their children before.
Frogs exchange gases through their skin and the lining of their mouths. This exchange of gases is referred to as respiration. During the larval stage in frogs development, it lacks functional lungs but they can take in oxygen through gills which are in process of metamorphosis.
The gills take in oxygen when water is being passed over them. Once lungs are mature, they lose their gills and are able to bring in oxygen through lungs.
They rely on lungs to breath when they are active and they need more oxygen than what skin respiration alone can provide.
Although they have oxygen, most of their respiration occurs through the skin.
The types of white blood cells that are available in ones immune system are phagocytes and lymphocytes.
well pal sorry but u forgot the imgs or what u needed us to do
Hey there!
Plants and Animals each have different system boundaries.
In plant cell contains a cell wall and a cell membrane while an animal cell only contains a cell membrane.
These help the cell by acting as a filter (i.e. They let some through while they prevent others from coming in.)
Thank you!
