Specific excretory organs are absent in unicellular organisms belonging to the<u> phylum Porifera.</u>
The organisms of the phylum Porifera are classified under the kingdom Animalia and they lack specific organs in their bodies.
The word "Porifera" refers to pore-bearing organisms.
These animals have loosely organized cells and are found in freshwater marine ecosystems.
On their body, a large number of pores - Ostia - are present which perform various functions such as excretion.
However, respiratory gases and waste materials are exchanged through a diffusion process.
Moreover, in them, reproduction takes place through fragmentation and budding.

A term named for a person or a place, such as alzheimer disease named for the physician who first described the symptoms as seen in a patient, is referred to as Eponym.
<h3>What is Eponym?</h3>
This is referred to as a place or a thing which is believed to be named after something and in this case, it is referred to as what we call Alzheimer which is common with older people.
Alois Alzheimer is referred to as a German neuropathologist who identified the first published case of presenile dementia in 1906 through the various symptoms he observed in the patient.
This was the reason why when this condition was fully confirmed by others later on it was named after him and is being referred to as Alzheimer disease today.
This is therefore the reason why Eponym was chosen as the most appropriate choice.

Answer: your bag will finish at 2112.
Explanation: (38gtt/min) × (10gtt/ml).
Cross multiply. (38gtt×1ml) × (1min×10gtt)
This gives you 38/10...and the gtts cancel out so, it's 38ml/10min.
Simplify this to 3.8 ml/min.
Now, 3.8ml/x min = 500 ml.
Take 500/3.8. This gives you about 132 minutes if you round to the nearest minute. 60 min/he means 132 min = 2h12m. 2h12m from 1900 is 2112.
