What is the difference ?
(a) Flowering plants – non-flowering plants
(b) A tree – a shrub
(c) Vertebrates – invertebrates

Answer 1

As per the given data the refractive index of glass with respective to air is 3/2 then the refractive index of air with respect to glass will be the inverse of the refractive index of glass with respect to air.

The inverse of 3/2 is 2/3. The reason is that the medium are interchanged but not completely altered.

If the medium is interchanged then there is the possibility for the alterations of the refractive index as all the medium will not be the same.

Answer 2

Answer:

(a)It's obvious nonflowering plants are different from flowering plants because they don't have flowers, but there is also a difference in how they reproduce. While flowering plants only use seeds, nonflowering plants use either seeds or spores. Spores are very tiny parts of a plant that can be used to reproduce.

(b) A shrub is defined as a woody plant that is smaller than a tree and generally has a rounded shape. The main difference between the two is that a shrub has several main stems growing from ground level, rather than one trunk.

(c)
