Answer and Explanation:
Yes, a single molecule can work through all three effector route. Cells commonly lead independent lives, and they might influence and communicate with other cells for sexual mating. For example, yeast cells communicate with one another for mating. On the other hand, animal cells communicate by different kinds of signal molecules. These molecules include amino acids, nucleotides, proteins, small peptides, retinoid, and derivatives of fatty acids and also includes dissolved gases such as carbon monoxide and nitric oxide. In the extracellular spaces, most signal molecules are secreted by the signaling cells. Some signal molecules are exposed to the extracellular spaces, while others are released by diffusion. Target cells respond by a specific protein called receptors. Receptors bind the signal molecules and start response in the target cell. On the surface of target cells, receptors are transmembrane proteins. When receptors bind extracellular signal molecules, they stimulated and produced a flow of intracellular signals that initiate the cells' behavior.
The molecular data are not found here but rabbits and whales are linked with the dogs and pigs in a cladogram due to evolutionary relationships.
<h3>What is a cladogram?</h3>
A cladogram is a graphical representation used to evidence the relationships between organisms due to a common evolutionary origin.
A cladogram is composed of a root that represents the common ancestor of the group and nodes where taxonomic groups diverge.
Cladograms based on molecular data use the homology level of nucleotide sequences of the genome to determine evolutionary relationships among individuals of different species.
In conclusion, rabbits and whales are linked with dogs and pigs in a cladogram due to evolutionary relationships.

The answer is c. the predators become the limiting factor for the pheasants in that environment.
Answer:
Charles Darwin spent almost 5 years in the voyage name HMS Beagle. This voyage made him famous as after returning, he formulated the "Theory of natural selection" as he was amazed by the geographical distribution of the wildlife and also collected fossils that helped him to formulate his theory.
Explanation:
Charles Darwin was the main contributor to the theory of evolution. Besides, he was a geologist, naturalist, and biologist. He first demonstrated the branching pattern of evolution on the basis of natural selection. 18 February 1809 was his birth date and he died in 1882. He explained the theory of natural selection with the help of finches residing in the Galapagos island. The change in the beak structure of the finches according to the availability of food illustrates the process of natural selection and hence the process of evolution.
Cladograms are detailed oriented and impossible to show evolutionary relationships and this among the following statements best describes a challenge in classifying organisms in this way. The correct option among all the options that are given in the question is the third option or option "C".
