<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
Answer:
There are three primary areas of the brain that control your sense of smell: The orbitofrontal cortex, located above and behind the eyes. The insula, which lies beneath the ears. The piriform cortex, located between the other two. Besides these three areas, there are smaller brain regions that also play a part in smell.
It's C! It changes as new evidence is found.
There are 6 carbon atoms in a glucose molecule. I hope this helps you☺
Asexual reproduction is a form of reproduction in which the number of chromosomes or the fusion of gametes is not altered.
Being genetically identical to the parent is advantageous for organisms when the environment changes fast, and reproduction is needed.
A gamete (a reproductive cell with one set of chromosomes, like an egg or sperm) combines with another to form a zygote, eventually developing into an organism of cells with two sets of chromosomes. Sexual reproduction is a type of reproduction that involves this complex life cycle (diploid).
The advantages of sexual reproduction are numerous. Several instances include:
more genetic variation
immunity against contagious diseases
fewer genetic diseases
Evolutionary fitness has increased
