Answer:

Oil immediately interferes with physical properties of feathers, hair and respiration, making it impossible for many animals to function properly.

Explanation:

For example, birds such as seabirds and bald eagles have to dive or get in the water at least partially in order to catch the fish they eat. Oil makes it impossible for these birds to locate their prey and when they get in contact with oil it makes it impossible for them to fly and be insulated against the cold. Otters and seals also lose insulation against cold water when their hair gets covered with oil and die of hypothermia. Orcas suffer from skin and eye irritation when they get in contact with oil and it may cause problems if it gets swallowed.

Tatiana [17]
<h2>a) is the correct option </h2>

Explanation:

The extracellular domain of the transmembrane receptor protein acts as binding site for primary messenger molecule whereas the transmembrane domain holds the receptor within membrane and the cytosolic domain has intrinsic tyrosine kinase activity, all these helps in proper cell signaling

If because of any mutation there is change in shape of the extracellular domain then that molecule that normally binds to the receptor protein will no longer attach hence cellular response will be deactivated
