Epidermis, dermis, and hypodermis
Answer:
A protein with its amino-terminus in the cytoplasm and its carboxy-terminus in the extracellular space. (Ans. A)
Explanation:
Integral membrane protein (IMP) is defined as a membrane protein molecule which is directly attached to the biological membrane known as phospholipid bilayers. All transmembrane proteins are integral membrane protein but not all integral membrane protein are transmembrane proteins.
Integral membrane proteins function as a transporter, receptors, channels, proteins which is responsible for cell adhesion, proteins are also Involved in transduction and build up of energy.
Membrane proteins are class according to their transmembrane domain properties. The N-terminus of an integral membrane protein type I is in the endoplasmic reticulum lumen, where N-terminus of an integral membrane protein type II in the cytoplasm.
Answer: Mitosis
Explanation:
Since meiosis helps only in the production of gametes, mitosis helps the somatic cells in the already fertilized egg (zygote) to do the following:
- multiply their number, thus aiding growth
- form new cells like red blood cells to transport oxygen, white blood cells to fight infection, liver cells etc
Thus, for growth mitosis is the mechanism used to generate more cells
