The answer is (1) It initiates a cascade.
Explanation:
Signal transduction pathways regulate many important cellular functions such as growth, differentiation, metabolism, and survival. Many of these signaling pathways are altered in human cancer.
<em>Receptor tyrosine kinases </em>are cell surface receptors that play a role in the signaling pathways governing cellular processes of metabolism, intercellular communications, differentiation, survival, and proliferation.
They bind to their corresponding growth factors, triggering the downstream signaling cascade.

Answer:
The Atomic number is 17 and Mass number is 35
Explanation:
<h3><u>Given</u>;</h3>
- No. of protons = 17
- No. of neutrons = 18
<h3>
<u>To</u><u> Find</u>;</h3>
So, For Atomic number
Atomic Number = No. of protons = No. of electrons = 17 (Which is Chlorine {Cl} )
Now, For Mass number
Mass number = No. of protons + No. of neutrons
Mass number = 17 + 18 = 35
Thus, The Atomic number is 17 and Mass number is 35
