Answer:
electrical energy
The generator, in turn, converts the mechanical (kinetic) energy of the rotor to electrical energy.
The answer would be D.
HWE states that genotype and allele frequencies in a population remain constant from generation to generation when evolutionary influences are absent(such as gene flow or natural selection).
It is a beneficial adaptation since the pressurized seeds and spores spread widely, helping the organism reproduce elsewhere. In plants, it allows them to survive better by flinging the seeds far away so that their offspring don’t compete for food. For the fungus, it allows the parent to fling the spores into the grass so that when other animals eat them, the life cycle of the fungus continues on. These may be dispersed by the wind.
Answer:
c. dendritic cells
Explanation:
An antigen presenting cell like dendritic cell is a part of adaptive immune system. When it encounters a harmful foreign antigen, it engulfs it via phagocytosis. The phagocytic vesicle fuses with the intracellular lysosome and here the antigen is broken into smaller fragments. With the help of MHC complex, these fragments are presented on the surface of dendritic cell hence it becomes an antigen presenting cell. This cell is then recognized by other cells of immune system like lymphocytes and destroyed.
Dendritic cells are present in skin and lining of lungs, nose, stomach, intestines. In skin they are called as Langerhans cells. Macrophages are another type of antigen presenting cells.
