Answer:
b. pseudocoelom
Explanation:
A pseudocoelom is a false body cavity of some invertebrates which occupies the space localized between the mesoderm and the endoderm of the gut. This false cavity is found in nematodes.
Arthropods exhibit:
1- Bilateral symmetry because both opposite sides of the body are similar,
2- they are protostomes because the blastopore becomes the mouth during embryonic development,
3- they have true tissues because tissues are formed by groups of cells which share a common function, and finally,
4-arthropods are triploblastic because they are formed by three germ embryonic layers (endoderm, mesoderm and ectoderm).
It’s important there’s molecules that could do so for keeping homeostasis, food movement, keeping the cell isotonic with movement of water, glucose to go into cell to not let it starve and waste to escape and not build up in cell
Answer:
The polluter is multiplied by covering the pyramidal base, that is, it affects all the following links that depend on the base of this pyramid, that is why the effect is multiplier, and much more serious.
Explanation:
If we analyze, the problem that is in the base creeps in all the following links, on the other hand, if the pollutant is in the third link of this pyramid it will only affect the last links, the lower the pollutant is, or more closer to the eastern base, the more negative repercussions it will have on the rest of the food chain.
The traditional example of this is the consumption of soya with pollutants in cattle, since it is dragged towards humans and all those animals that continue in the food chain.
