Hii!! I believe the answer is fetal stage. (:
Good composting practices minimize greenhouse gas emissions. The use of compost provides numerous greenhouse gas benefits, both directly through carbon sequestration and indirectly through improved soil health, reduced soil loss, increased water infiltration and storage, and reduction in other inputs.
How can I help lower the greenhouse gases in the atmosphere?
How can I use composing to lower the greenhouse gases?
Answer:
Antigens that activate B-cells with the help of T-cells are called as T-cells dependent antigens. They are called as such because they are not able to induce a humoral response in organisms that lack T-cells. B-cells response to these antigens take many days, thought antibodies generated are more versatile and have a higher affinity than those generated from T-cell independent activation.
So, the steps for activation of a B cell by a T-dependent antigen are:
(1) Immunoglobulin receptors on the B cell recognize and bind the antigen.
(2) An antigen fragment in complex with MHC class 2 is displayed on the B cell's surface.
(3) The MHC-antigen complex binds a receptor on a TH cell.
(4) The TH cell secretes cytokines that activate the B cell.
I'm pretty sure it's Latin, acer means tree and I think rubrum is red
