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.

In the following orbital the lone pair on each N atom is present:
N1: sp3,
N2: p,
N3: p,
N4: sp2,
N5: sp2
Sitagliptin is an anti-diabetic drug used to treat type 2 diabetes and is marketed under the brand names Januvia and others. One carbon atom has no pi bonds, while the first nitrogen atom is linked to two hydrogen atoms. It thus possesses sp3 hybridization.
The second nitrogen atom possesses a single pair of electrons and is bound to three other atoms. It is hence sp2 hybridized. The nitrogen atoms in positions 3, 4, and 5 have sp2 hybridization.
The lone pair of nitrogen in the first nitrogen atom is in the sp3 orbital. The second and third nitrogen atoms' only pair of electrons are in p-orbitals. The fourth and fifth nitrogen atoms' lone pair of electrons are in sp2 orbitals.

Answer:
ETHICS :
Ethics or moral philosophy is a branch of philosophy that "involves systematizing, defending, and recommending concepts of right and wrong behavior".The field of ethics, along with aesthetics, concerns matters of value, and thus comprises the branch of philosophy called axiology.
Ethics seeks to resolve questions of human morality by defining concepts such as good and evil, right and wrong, virtue and vice, justice and crime. As a field of intellectual inquiry, moral philosophy also is related to the fields of moral psychology, descriptive ethics, and value theory.
Three major areas of study within ethics recognized today are:
1. Meta-ethics, concerning the theoretical meaning and reference of moral propositions, and how their truth values (if any) can be determined
2. Normative ethics, concerning the practical means of determining a moral course of action
3. Applied ethics, concerning what a person is obligated (or permitted) to do in a specific situation or a particular domain of action.
MORALS :
A moral (from Latin morālis) is a message that is conveyed or a lesson to be learned from a story or event. The moral may be left to the hearer, reader, or viewer to determine for themselves, or may be explicitly encapsulated in a maxim. A moral is a lesson in a story or in real life.
