Answer the following question given this paragraph: Radioactive strontium is dangerous because it can chemically replace calcium in the human body. The bones are particularly susceptible to radiation damage. Write the nuclear equation for the beta emission of strontium-90. Q: What can radioactive strontium replace in the human body making it dangerous? Choices: - potassium - oxygen - magnesium - calcium A:
(Answer)
calcium
Ques: Answer the following question given this paragraph: Receptor tyrosine kinases epidermal growth factor receptor (EGFR), platelet-derived growth factor receptor (PDGFR), vascular endothelial growth factor receptor (VEGFR), HER2/neu Receptor tyrosine kinases add phosphate groups to other proteins to activate or inactivate them. Receptor kinases add phosphate groups to receptor proteins at the surface of the cell. These receptor proteins receive signals from outside the cell and initiate a signal transduction process inside the cell. Tyrosine kinases add phosphate groups to tyrosine residues in the target protein. They can cause cancer by turning the receptor permanently on (constitutively), even without signals from outside the cell. Q: What adds phosphate groups to receptor proteins at the surface of the cell? Choices: - nitrogen kinases - brain kinases - protein kinases - receptor kinases A:
Ans: receptor kinases
(Q).

For example, it is the distance between two adjacent crests in the transverse waves in the diagram. Infer how wave frequency is related to wavelength. Q: The wavelength of a wave is the distance between corresponding points on what? Choices: - distant waves - spectrum - basic waves - adjacent waves A:
(A).
adjacent waves
Ques:Answer the following question given this paragraph: Genetics is the study of inheritance. The field of genetics seeks to explain how traits are passed on from one generation to the next. Q: What field of science seeks to explain how traits are passed on from one generation to the next? Choices: - zoology - biochemistry - quantum physics - genetics A:

Ans:genetics
