Serjik [45]

The drug that to a receptor in the nucleus. This binding makes on a gene to make a protein. This drug is actually lipophilic and hydrophobic, the correct option is A.

What is receptor?

In biochemistry and pharmacology, receptors are protein-based chemical frameworks that transmit and receive signals that can be assimilated into biological systems.

As the drug is crossing the lipid membrane so it should be lipophilic and hydrophobic to be able to bind the receptor as in the given situation.

Thus, the correct option is A.

blondinia [14]

Answer:

The resistance of the device is 27Ω

Explanation:

When a device is used in a circuit in which the voltage is 81 V, the current flowing through the device is 3 A.

In order to calculate the resistance of the device, we know that the resistance is directly proportional to the voltage in the terminals of the device and the current flowing through it.

Using Ohm's law

R=\frac{V}{I} \\R=\frac{81V}{3A}=27Ω
