Grasslands typically do not flourish when large herbivores are removed. In fact, they are soon replaced by broad-leaved herbaceo

JulijaS [17]

Answer:

Grasslands and herbivores have a mutually beneficial symbiotic relationship. If larger herbivores such as Kangaroos and Elephants are removed from them, they may become extant.

Explanation:

Herbivores are always hungry and they are always looking for ways to replenish lost energy. Between tree shoots and grass, they often go for the former because they are tender, easier to reach, and less difficult to masticate than the young tree shrubs.

When baby trees become bigger, their shade prevents adequate sunlight from reaching the grass, then gradually they become scanty or subdued for as long as the shade remains.

When large herbivores are removed or leave a grassland, trees have the ability to flourish. Then the results indicated above happens.

Cheers!

Which claim is best supported by the information about scales and feathers?

alexandr402 [8]

Answer:

Recent evidence suggest that feathers evolved from scales and suggest that 'feathers and pycnofibers' could be homologous.

Explanation:

One of the major difficult issue related to bird evolution is the evolution of feathers.

Feathers are considered as the most 'complex integumentary structures' which are found in vertebrates.

Evolutionary developmental biology suggests that the 'planar scale structure' is been modified for developing into feathers by 'splitting' to form web like structures.

Scales and Feathers consist of 'two distinct form of keratin' so it was thought that 'each type was exclusive skin structure' but recent study suggests that they are developmental expressions of same skin structures.
