  1. frogs do not have those because they can get enough oxygen through their skin. since their skin can only function when moist they rely on water more than true land animals

  2. Yes,
    bcoz frogs become amphibian and amphibian means who lives both water and land and frog mostly likes to live in water so that’s right .

  3. it is not fully land animal as its 1st stage of life is larvae stage which requires water.
    its larvae stage has gills as respiratory organ n not skin.

  4. frog anatomy have certain points
    Frogs don’t have ribs or a diaphragm and lungs are reduced and tubular when frog lives out of water for some time only that time these are being used that too of primitive type their lungs are standby otherwise there would have been a strong thoracic cage as humans for supporting respiration , their skin is vascular then man for taking dissolved oxygen when in water. there is big difference in blood circulation system and heart that is is three-chambered with two atria and one ventricle.
    single cloaca opening
