False. A reduction in lot sizes does not enhance the amount of variation that can build up between any two supply chain stages, hence enhancing the bullwhip effect.
According to the bullwhip effect, which is a characteristic of the suppliers chain, modest changes in demand at the retail level can lead to steadily increasing changes at the wholesale, distributor, manufacturer, and raw material supplier levels. The physics of cracking a whip are referenced in the effect's name. The comparatively tiny movement of the whip's wave patterns increasing in size as a result of the person holding it snapping their wrist. In supply chain management, salespeople, manufacturers, suppliers, and customers all have a partial understanding of demand and limited direct control over it.

Answer:
The correct answer is: C) E,A,B,D,C.
Explanation:
Bone fractures occur when a trauma generated a breach in the continuity of the bone. When a bone fractures, a process called secondary healing starts.
The first step in fracture repair is the removal of dead tissues - this is done by specialized cells called phagocytes and osteoclasts, that proceed by "eating" the damaged tissues.
Next, a hematoma forms because the blood vessels surrounding the fractured bone were ruptured. This hematoma clots and forms the temporary frame for the process of healing that is happening.
Mesenchymal stem cells migrate to the area and begin to differentiate into fibroblasts and chondroblasts, which is important for the production of fibrocartilage, a tissue that will connect the ends of the broken bone.
Then, osteoprogenitor cells differentiate into osteoblasts, which are the cells that synthesize bone tissue. These osteoblasts will produce spongy bone. The newly-formed fibrocartilage tissue becomes calcified.
Finally, osteoclasts begin with a process called resorption, which consists of resorbing the dead portions of the new bony area. This resorption is coupled with osteoblasts' bone synthesis. These two processes that occur together are fundamental for bone remodeling, which will end up with the spongy bone being transformed into compact bone.

Explanation:
The immune system allows us to discriminate from the outsider.
There is innate immunity which we carry from birth and protects us against antigens; correspond to barriers that prevent harmful bodies from entering the body.
It is composed of some of these components:
- Skin and mucous membranes (physical barrier): the skin has microorganisms that inhibit the growth of pathogens.
-NK cells (natural killer): they are leukocytes that recognize changes in the cell surface of cells infected by viruses and tumor cells. These target cells are recognized by NK cells, which trigger cytotoxic response and destroy them.
- Neutrophils: white balloons with granules that release enzymes that destroy and digest cells.
-Cytokines (including interleukins 1 and 6, interferons, tumor necrosis factor: TNF): they are low molecular weight proteins that generate immune system response by recruiting or inhibiting the functions of specific cells (dendritic cells) or neutrophils, regulate proliferation and cell differentiation, activate or inhibit the expression of some genes.
