Answer 1

1) lungs, mouth cavity and nostril
2) it helps prevent from dust particle to enter through our nose by sticking on the mucus,helps to warm the inhaling air in cool weather, nasal passage is lined with hairs called cilia.
3) small amount of oxygen is carried in the plasma as a dissolved gas, the protein inside RBC carries oxygen.
4) 1 through gills, 2 through lungs, 3 through tracheal system,4 through integumentary system.

Answer 2

$Hey...$

Here is your answer...

1). The different modes of respiration in frog are skin, lungs and lining of the mouth.

The reason behind different modes is the amphibious mode of life.

2). Nasal cavity is a hollow structure which lies between nose and skull. It is being lined with mucus and contains hair so as to perform different function.

Those function is to warm and moisturize the air which is gonna reach the lungs.

Also the hair purifies the air and don't let any dust come in.

3). Our blood contains a pigment called haemoglobin which carries oxygen to cell.

There's a protein haemoglobin which serves the important function I.e., binds the oxygen.

4). Mainly there are four ways by which exchange of gases take place. They are :

➡ Gills (in water animals)

➡ Skin

➡ Tracheal system (in insects)

➡ Lungs (land animals)

Hope it helps..
