Answer:
Isometric contraction
Explanation:
The length of the muscle is changed during contraction only when the muscle tension during contraction can outstand the resistance exerted by the object to be lifted.
During isometric contractions, the muscle tension is not sufficient to exceed the resistance of the object. Hence, there is no change in the length of the muscle. The isometric contraction does not bring about any body movements.

Answer:
The new drug will not be effective against the treatment of cancer.
Explanation:
The drug will not be effective against the cancer treatment because the drug will inhibit the dimerization of receptor tyrosine kinase (RTK) but as the Ras has undergone mutation due to replacement of one amino acid, it will be constitutively expressed and the drug is not effective in stopping the Ras functioning.
Thus, Gefitinib cannot work against the cancerous cell as it is not potent to stop the functioning of mutant Ras protein.
