2.
3. Each cell makes a complementary DNA strand.
4. The cells separate.
Which is the missing step for the process of conjugation described?
O
Two new, identical cells are produced.
The cell membrane elongates and pinches off.
Some DNA moves from one cell to another.
A DNA molecule attaches to the cell membrane.

hi~~

i would say that hybridization occurs frequently in nature, because there are many types of hybrids that have occurred naturally, such as the mule (male donkey + female horse)

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.
