Answer:
a. Mammalia
Explanation:
Mammalia are the class species that have distinct systems and separate ducts for different activities like reproduction, excretory, and defecatory and moreover they have nipples to feed their young ones.
So, the above species which has a single duct for reproductive, excretory, and defecatory material as well as a lack of true nipples does not belong to Mammalia
A
Because grass is a plant so it’s like living compared to water and being active isn’t even a part of the environment
I think salt is it

Answer:
Among the seven characteristics in life, the one should be sensitivity. It is where living organisms detect and react to stimulus or changes to the environment.
Specifically among plants, this change is called a tropic response, or tropism for short. Plants reacts to aspects like light, gravity, or water.
This response is controlled by a plant hormone called auxin. Auxin is produced at the tip of the plant, and they diffuse among the plant. The auxin accumulates at the side of the plant that doesn't receive as much sunlight, and auxin can stimulate its growth on that side so the plant bends. That's how a plant bending works.
Anyways, the answer to the question should be sensitivity.
Answer:
speciation is when one species splits off into multiple species.
In-depth answer:
Speciation can happen in 4 different ways, the first being Allopatric Speciation, where 2 groups of the same species are physically separated for extended periods of time, and when they're re-introduced, they don't breed.
Sympatric Speciation is when 2 groups of the same species aren't seperated, but form different behaviors that isolate them reproductively (the groups wont inter-breed)
Parapatric Speciation is when 2 groups of the same species are suddenly placed into a new environmental niche, and adapt in different ways to fill that niche.
Quantum Speciation is much less recognized, but it's when a new species rapidly evolves and 'buds off' from the original group
