The disadvantages of the pyramid of productivity as a representation: The rate of biomass production of an organism is required, which involves measuring growth and reproduction through time. There is still the difficulty of assigning the organisms to a specific trophic level.
Answer: White blood cells form to fight off cell infections.
Explanation:
1. Your body produces white blood cells which fight against infected cells, depends on what type of cell it is and how infected it is.
2. The immune response to a viral infection is primarily generated by a type of white blood cell called lymphocytes; cells that are mostly localized in ‘lymphoid tissues’ such as the lymph nodes or tonsils. However, the number of lymphocytes that can recognize and react against any individual type of virus is initially very small. This is particularly true for a novel virus such as SARS-CoV-2, which people have never encountered before. In order to produce an effective immune response, the small number of lymphocytes that can recognize a virus must become more abundant. Even though lymphocytes proliferate quickly it still takes several days before there are sufficient cells available to fight back against the infection. During this period the virus may also be spreading rapidly, so there is a race between the virus and the immune system that may determine the final outcome, in terms of recovery.
Distillation is a process of separation of two liquids on the basis of their difference in the boiling points. There are two types of distillation process- Microscale distillation and miniscale distillation depending on the type of apparatus used for distillation.
In case of microscale distillation, microscale apparatus is used when the volume of liquid to be distilled is less than 5 ml. Whereas, in case of miniscale distillation, miniscale apparatus is used when the volume of liquid is more than 5 ml.
Hickman distilled head is used for microscale distillation whereas a bit larger vessels are used in miniscale distillation.
Micorscale and miniscale techniques have their own advantages. Both these techniques are cost effective, use less equipments and environmental friendly. Miniscale distillation is used yields more product which is easy to measure. Microscale distillation are difficult but it avoids large cumbersome distillation process and instruments.
