<span>Except for identical twins, all the other human beings are genetically distinct from each other is ture because of </span>sexual reproduction.
4. All of the above, after order tha classifications goes family, genus, species.
The plasma membrane can be most accurately compared to human skin. Skin protects our insides from many different things just as the plasma membrane does for cells.
Innate behavior is the behavior that is not learned
Following are examples
<span>The courtship of the Blue-footed Booby as they dance on their feet to impress the female
</span>The little chicks hatching from eggs
they don learn it they have already these
learned behavior types are
Imprinting..a newly hatch chicks follow mother
Habituation..a turtle that draws it head when touched
sensitization.when siphon is gently touched
conditional response
child cry due to injection
hope it helps
Answer:
Cell membrane or plasma membrane is the semi-permeable outer layer surrounding the components of the cell.
It is important to the cell as it provides important properties to the cell as it separates the aqueous interior of the cell from the external environment, helps in cell–cell contact, in surface recognition, signaling and transport.
The plasma membrane is made up of different types of molecules like phospholipids, proteins, cholesterol, carbohydrates providing flexibility to the layer so, the model of membrane is known as fluid mosaic model.
The primary constituent of membrane is a lipid molecule called Phospholipids which is made up of glycerol molecules attached to a phosphate group and forms a hydrophilic head while long fatty acyl chains attached to the head froms hydrophobic tails.
It is the fatty acid chains which provide hydrophobic nature to the cell membrane. These layers are arranged in the form of bilayer with head towards outside while tails inside.
Along with phospholipid membrane posses peripheral and integral proteins which helps in transport of the molecules across membrane.
