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.
I just took the review the correct answer is D, I, II, III, and IV
Umm what do you want me to do i dont undrestand
Answer:
Cystic fibrosis
Explanation:
X- linked trait may be defined as the trait that is located on X chromosome or the inheritance of the trait is based on the X chromosome. The disorders associated with X-linked trait is known as sex linked disorder.
Cystic fibrosis is an autosomal recessive disorder that affects the digestive system, lungs and liver. The homozygous recessive condition is responsible for the disease cystic fibrosis. Hence, cystic fibrosis is not an X-linked trait.
Thus, the correct answer is option (2).
