Explanation:
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.
When a neuron carries the electrical potential of -70 millivolts, it is in the state called RESTING POTENTIAL. At the resting stage of the neuron, the inside of the neuron is 70 millivolts less than the outside. At this stage, there are more sodium ions outside the neuron and more potassium ions inside the neuron.
<span> A plant with narrow leaves and shallow roots would probably be found in the desert, where there is not a lot of water. Narrow leaves help prevent water loss. Shallow roots can spread out long distances in search of water. Plants living in the desert grow far apart from one another so that they don’t have to compete for limited amounts of water.</span>
C - it increases stamina and reduces fatigue.
While stress and boredom reduction are also true, they are not cardiovascular benefits in this case. For that reason, answer C is the correct one. When one starts being physically active for a certain amount of time, increased stamina and reduced fatigue will follow.
