Answer:
Karyogram of a male with Down syndrome.
Answer:
Fungi
Explanation:
Fungi is a eukaryotic organism that is re-evaluating its position in the tree of life.
Fungi are closely related to the animal kingdom in comparison to the plant kingdom. Because of the presence of the chitin in their cell walls, fungi is different from plant, bacteria, and protists. But fungi have cell wall while animal cells do not contain cell wall, so not classified as animals.
So, fungi is re-evaluating its position in the tree of life and in present there is a individual kingdom for fungi.
Answer:
Receptors are highly specific and only have high affinity for those ligands for whom they are specific.
Explanation:
Receptors are proteins that receive a stimulus or bind a ligand and mediate effects via receptor effector system.
Receptors are macromolecules that are highly specific.
The affinity between the ligand and the receptors is determind by the disassociation constant Kd.
The receptors produce maximun effect when an appropriate specific stimulus is present.
Different recptors types are present for different ligands.
For example, muscrinic receptors are specific for acetycholine and adrenergic receptors are specific for adrenaline/nor adrenaline.
It is important to know the specificity so that the body remains in a state of balance.
