<h2>Answer:</h2>
Carbon moves from land to bodies of water as in following steps.
Carbon in the land is present in form of fossil fuels and plants and animals.
It converts into CO2 gas form by the burning of fossils and respiration of plants and animals.
This atmospheric CO2 is used by plants in water for photosynthesis.
Water bodies eat these plants for their nutrition. And use that carbon for making there carbohydrates, lipids and proteins.
Hence making land carbon their body part.
Receptors that are embedded on the cell membrane bind to chemicals outside of the cell and this binding process cause a chemical response on the inside of the cell.
These receptors that help in communication between the cell and the outside world are called cell surface receptors or sometimes transmembrane receptors.
A majority of chemical signals are water soluble thus unable to cross the fatty lipid bi-layer of the cell membrane. Their receptors, which are protein in nature therefore must span the membrane, detect their presence outside of the cell and transmit this information into the interior of the cell.
Answer:
The correct answer will be option-C
Explanation:
Comparative anatomy is the branch of study which studies anatomy or skeletal structure of the different species and comparing them to study the relationship between them.
The comparative anatomy is studied to study the evolutionary relationship between the different species which acts as evidence of the evolution. The study has distinguished the skeletal structure as homologous structures or analogous structure.
The correct answer will be option-C.
