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.
Answer:
A
Explanation:
Adding salt to water causes its density to increase. Denser water will sink below less dense water.
They are animal organelles that remove wastes from the cell
Answer:
<em>The genotype of the mother will be Bb.</em>
Explanation:
A punnet square can be described as a diagram which is made to depict the outcome of a cross.
In the scenario discussed in the question, the genotype of the male parent will be bY. This is because he has the recessive black spots. As he is a male, he'll only have one allele for this gene.
In order to have one of spot design for each gender, the mother will have the genotype Bb.
The punnet square will be as follows:
b Y
B Bb BY
b bb bY
