True

There are more smooth muscles as opposed to skeletal muscles
Answer:
The entrance of the antigen activates cell signaling pathways through cytokines secreted by B cells, thereby triggering an immune response >> Subsequently, B cells also act in antigen processing by presenting them to T-cells.
Explanation:
An antigen is a molecule that binds to an antibody or a B cell receptor. Cell interaction is produced by direct contact of cells in multicellular organisms and this interaction may also be associated with immune responses through intercellular communication by cytokines. The cytokines are released and then bind to cell receptors to trigger an immune response (for instance, inflammation). It is possible to trace the secretion of cytokines and their corresponding receptors by analyzing specific gene expression patterns. The B cells are critical components of the immune system because they release cytokines in response to antigenic stimuli, and they also present antigens to T cells.
Cell A is more efficient at exchanging substances due to larger surface area to volume ratio.
Cell A is more efficient at exchanging substances with the surrounding environment than cell B because it has the larger surface-area-to-volume ratio. Larger surface area of the cell exchanges more substances with the surrounding environment while on the other hand, lower surface area of the cell exchanges less materials with the environment so we can conclude that cell A is more efficient at exchanging substances due to larger surface area to volume ratio.

Explanation:
Answer:
The differences between Mitosis and meiosis is Mitosis involves the division of body cells, while meiosis involves the division of sex cells. The division of a cell occurs once in mitosis but twice in meiosis. Two daughter cells are produced after mitosis and cytoplasmic division, while four daughter cells are produced after meiosis
