Answer:
Enzyme-linked
Explanation:
The cell surface receptors that have intracellular domains associated with enzymes are called enzyme-linked receptors. The added molecule was water-soluble and cannot pass through the membrane to bind to intracellular receptors. Binding of the added molecule to the enzyme-linked receptor led to the activation of associated enzymes to generate the response (down-regulation of expression of the target gene).
Examples of enzyme-linked receptors include tyrosine kinase receptors. Binding of the signaling molecule to these receptors triggers phosphorylation of the intracellular domain which in turn transmits the signal to the cytoplasmic messenger.
Answer:Enrico must multiply the distance of mars from sun (meters) with the 
to convert the distance in astronomical units.
Explanation:
1 astronomical unit = 
Let the distance between the sun and Mars be Y( meters)
Distance in AU=
