Multiple methods of reproduction support the longevity of sponges in the fossil record is described below.
Explanation:
Sponges are able to reproduce both sexually using gametes and asexually by budding. Even though sponges are hermaphroditic, individuals will only make one type of gamete at a time. There are two forms of asexual reproduction that sponges can go through: external budding and internal budding.
Sponges reproduce sexually, too. Sponges do not have separate sexes-a single sponge forms eggs at one time of the year and sperm at a different time. At any one time of the year, some sponges are producing eggs and others are producing sperm.
The volume of water passing through a sponge can be enormous, up to 20,000 times its volume in a single 24 hour period.
Sponges reproduce by both asexual and sexual means. Most poriferans that reproduce by sexual means are hermaphroditic and produce eggs and sperm at different times. Sperm are frequently "broadcast" into the water column. ... Some sponges release their larvae, where others retain them for some time.
In Pavlov's original studies on classical conditioning, he used dogs as the subject of his experiment. The unconditioned stimulus was the <u>bowl of food</u> that he presented to the dog while the unconditioned response was the dog salivated in its excitement to see the food.
