The correct answer is number 2. The reason is the carbonation in the soda water will eventually stop bubbling and therefore the water molecules will still exist.
All the different plant populations make up the plant community in this swamp. The plants are part of a bigger ecosystem that contains many abiotic and biotic factors.
<h3>What is an Ecosystem?</h3>
An ecosystem may be defined as a place or an area that involves individuals of different species that live together and interact with one another for the purpose of food, shelter, and space.
In ecology, a community may be defined as a group of individuals belonging to different species that are living in the same area at a given time.
So, all the different plant populations make up a plant community.
Therefore, the community is the collection of all different forms of species but the ecosystem is the community has highly influenced by abiotic and biotic factors.

Answer:
The correct answer would be a lipid-soluble signal.
Signal transduction refers to the set or cascade of bio-chemical reactions take place in a cell in order to transmit the chemical or physical signal from outside the cell to inside target molecule.
It is usually initiated by receptors present on the membrane of the cell which sense the extracellular stimulus (such as ligand, hormone, pressure, temperature, pressure etc). Once activated, these receptors activate the cascade of reaction which ultimately reaches the target molecule and produces a cell's response.
In contrast, the lipid-soluble signals (such as steroidal hormones, thyroid hormone etc) enter the cell membrane without any hindrance. They directly bind to intra-cellular receptor present in the cytoplasm or on the nuclear membrane.
The hormone-receptor complex then enters the nucleus and act as transcription factor and produces the response in the form of transcription.
