While the surface temperatures can vary quite a bit, changes in temperature at the tropopause levels change much slower and are tied more to the time of year.<span>

Answer:
B. Monoclonal antibodies are produced from plasma cells
Explanation:
An antigen is a molecule present on the surface of a pathogenic organism and they are capable of generating an immune response by binding to specific antibodies (immunoglobulins) that are secreted by lymphocytes B cells of the immune system. B cells are a type of white blood cell that plays key roles during humoral immunity of the adaptive immune system. When an antigen is introduced into the organism, a specific lineage of B cells proliferate, in a process known as monoclonal expansion.
You start by answering the first question on the list which tells you what to do from there. Pretend your animal was a bird, you might have a key like this:
Does this animal have wings?
yes go to question 2
no go to question 6
Then you just continue until the list doesn't say to do anything else. i.e.:
Is the animal feathered?
yes bird
no go to question 4
If I remember correctly I think its "antidiuretic"
Answer:
B) mitosis and cell differentiation.
Explanation:
Embryonic development of a multicellular organism has several stages.
In principle, cell multiplication occurs through the mitosis process in which each cell produces two identical daughter cells, in this phase the number of cells that make up the embryo is gradually increased.
The next phase corresponds to the cell differentiation in which by means of modifications in the gene expression, the cells acquire the morphology and the functions of a specific cell type and different from the rest of cell types of the organism
