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.

Maksim231197 [3]

Answer:

Euhaline  ⇒  Polyhaline  ⇒  Mesohaline  ⇒  Oligohaline

Explanation:

Let's first define each of these levels:

- Polyhaline: a category of salinity that has medium-high levels of salt

- Mesohaline: a category of salinity that has medium levels of salt

- Oligohaline: a category of salinity that has low levels of salt

- Euthaline: a category of salinity that has high levels of salt

Now, we can order these in decreasing order of salinity:

Euhaline  ⇒  Polyhaline  ⇒  Mesohaline  ⇒  Oligohaline
