Which of the following best compares hyphae and gametangia in fungi?
a. hyphae transport water and nutrients, while gametangia store spores.
b. hyphae produce spores, while gametangia develop into gametes.
c. hyphae release enzymes to break down food, while gametangia produce gametes.
d. hyphae provide structure and support, while gametangia release spores.

answer: d. hyphae provide structure and support, while gametangia release spores.

the fungi is group of saprophytic organisms which feeds upon the dead and decaying plants and animal matter. the body of the fungi consists of numerous filamentous structures called as hyphae. these hyphae forms a network which is called as mycelium. the fungal hyphae has a function related to the attachment and absorption of nourishment from the dead matter. it releases enzymes to break down complex organic matter into simple substances. the tip of some hyphae develops a sexually reproducing structure called as gametangium. the hyphae bearing gametangium of opposite strain fuse to form diploid zygote. the zygote undergoes meiosis to form haploid spores.

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
