Match each activity to the advantage it provides in reproduction? ?

Parthenogenesis- Continues reproduction despite single-gender dominance.
Parthenogenesis is a form of asexual reproduction (reproduction requiring only one parent) that allows a female organism to give birth to young one without the presence of a female. 
 
Broadcast spawning- allows large production of offspring. 
Marine animals, especially the bony fish, commonly reproduce by broadcast spawning, which is an external method of reproduction where the female releases many unfertilized eggs into water and at the same time the male releases a lot of sperm into the water which fertilizes some of these eggs. 

Pollination - Obtains genetically different varieties of plants.
Pollination involves the transfer of pollen grains from the stamens, the flowers parts that produce pollen grains, to the ovule-bearing organs or to the ovules. There are many advantages of pollination especially the cross pollination most importantly the introduction of genetic diversity to the plant, which keeps them resistant to diseases. 

Herding- protects calve from predators
Many types of animals seek the company of others. Several benefits are gained by the act of gathering into groups of the same species which includes safety from predators, access to mates, and help in finding food.

parthenogenesis: continues reproduction despite  single-gender dominance

pollination: obtains genetically different  varieties of plants

herding: protects calves from predators

broadcast spawning: allows large-scale production of  offspring
