    Feb 02, 2021 The primary reproductive organs of either system are called gonads (ovaries and testes) and these are responsible for gamete (sperm and egg cell) and hormone production. Other reproductive structures and organs are considered secondary reproductive structures and they aid in the growth and maturation of gametes and offspring.

  • 12 Differences between Primary and Secondary Immune Response 12 Differences between Primary and Secondary Immune Response

    Apr 29, 2021 Differences between Primary and Secondary Immune Response. In a primary immune response, naive B cells are stimulated by antigen, become activated, and differentiate into antibody-secreting cells that produce antibodies specific for the eliciting antigen. A secondary immune response is elicited when the same antigen stimulates memory B cells, leading to the production of …

    Sep 04, 2021 When cells are combined into batteries, the potential of the battery is an integer multiple of the potential of a single cell. There are two basic types of batteries: primary and secondary. Primary batteries are “single use” and cannot be recharged. Dry cells and (most) alkaline batteries are examples of primary batteries.

    93. Primary and secondary antibody response differ in all the following ways, except A. IgG production predominates in secondary responses. B. the lag period between antigen stimulation and antibody response is shorter in the secondary response. C. the rate of antibody production is faster in primary responses than in secondary responses.

    Jan 10, 2015 Germanium is a semiconducting metalloid element. Its principal applications are in optical fibers, catalysis, infrared optics, solar cells, and light-emitting diodes (LEDs).1 The need for Ge in these markets is considered to increase by a steady ~1% on a yearly basis.2 Therefore, germanium is an economically important element. The abundance of germanium in the Earth’s crust averages 2 ppm.3 ...

    Production of cell suspension culture and hairy root cultures from callus. The primary limitation of suspension culture for secondary metabolite production is that often the cells produce little of the secondary metabolites in the undifferentiated state. Suspension cultures will be initiated from the established callus cultures in a liquid ...

    Oct 20, 2017 The rates of secondary production, as we will see in a coming lecture, are very much lower than the rates of primary production. An everyday example of how GPP, NPP, and R are related. To better understand the relationship between respiration (R), and gross and net primary production (GPP and NPP), consider the following example.

    Sep 15, 2010 In a B cell primary response to a thymus-dependent antigen, the immune system selects B cells with a high affinity and specificity for the antigen and these become memory cells. The selection of B cells with a high affinity for a given antigen occurs in the germinal centres of secondary lymphoid follicles and requires the enzyme activation ...

    Aug 31, 2015 Primary Cell Culture: Primary cell cultures have finite life spans. As explained above, this is because the growth of cells exhausts substrate and nutrients and leads to accumulation of toxic metabolites. As a result, gradually the growth rate of cells drops, leading to the death of cells. Secondary Cell Culture: Secondary cell culture prolongs ...
