The correct answer is option A, that is, Phylum Porifera.
The species of Phylum Porifera are aquatic, that is, mostly marine. They exhibit cellular grade of the body, they are diploblastic animals with asymmetrical symmetry. They lack body cavity and exhibits a holozoic mode of nutrition with intracellular digestion.
They lack circulatory and nervous system and possess the tendency to regenerate their parts of the body. The organisms in phylum Porifera exhibits both asexual and sexual mode of reproduction.
They are much much smaller and much much cooler despite being much much closer to the sun.the gas giant's mass allows for constant movement and friction which warms up it's core.
This is such a vague question. Are you asking what it is or how to trace the process?
Water treatment<span> is any process that makes </span>water<span> more acceptable for a specific end-use. The end use may be drinking, industrial </span>water<span> supply, irrigation, river flow maintenance, </span>water<span> recreation or many other uses including being safely returned to the environment.</span>
<span>If factors are only
rounded up, then the estimate is an overestimate. If factors are only rounded down, then the
estimate is an underestimate. When some factors are rounded up and some are rounded
down, it is harder to tell whether the estimate is an overestimate or an underestimate.</span>
Carbon Monoxide. Carbon Monoxide is polluting the air not water, everything else on the list is something that can pollute the water.
