(b) bread mould
Bread mould is a common type of fungus
It grows and reproduces the same way that most molds do
In asexual reproduction, the mold makes spores inside a sporangium
The spores land on a place where they can turn into a new mold, and begin to grow
It is part of the fungi kingdom
Hope this helps :)
The demand for fish will increase at every price.
Sea stars are members of class Asteroidea and are the most well known members of Echinoderms.

</h3><h3>
What are the characteristics of Sea stars?</h3>
- The sea stars, or members of the class Asteroidea, are among the most well-known echinoderms.
- There are more than 1,800 species of them, and they come in a wide range of sizes, colors, and shapes.
- Five thick arms that stretch from a central disk where organs penetrate the arms are one of the features of sea stars that distinguish them from other echinoderm classes.
- Sea stars utilize their tube feet to hold prey as well as to grip surfaces. They can evert one of their two stomachs, which they have, through their mouths to exude digestive juices into or onto prey before absorption.
- Sea stars have two stomachs. By effectively liquefying the prey, this procedure helps facilitate digestion.
<h3>What are the functions of echinoderms highlighted in Sea stars? </h3>
- Like other echinoderms, Sea stars are radially symmetrical with pentamerous radial symmetry, coelomate, triploblastic and have organ-system level of organization.
- Pedicellariae are present.
- Calcareous endoskeleton made of ossicles is present that gives them a spiny appearance.
- Water Vascular System is present which is the most distinctive features of echinoderms.
