Answer:
B cells are part of the immune system and develop from stem cells in the bone marrow. Also called B lymphocyte. Enlarge. Blood cell development. A blood stem cell goes through several steps to become a red blood cell, platelet, or white blood cell.They fight bacteria and viruses by making Y-shaped proteins called antibodies, which are specific to each pathogen and are able to lock onto the surface of an invading cell and mark it for destruction by other immune cells. B-lymphocytes and cancer have what may be described as a love-hate relationship.B cells are activated when their B cell receptor (BCR) binds to either soluble or membrane bound antigen. This activates the BCR to form microclusters and trigger downstream signalling cascades.Once activated B cells may undergo class switch recombination.
T cells are part of the immune system and develop from stem cells in the bone marrow. They help protect the body from infection and may help fight cancer. Also called T lymphocyte and thymocyte. Enlarge. Blood cell development.T cell, also called T lymphocyte, type of leukocyte (white blood cell) that is an essential part of the immune system. T cells are one of two primary types of lymphocytes—B cells being the second type—that determine the specificity of immune response to antigens (foreign substances) in the body.They focuse on specific foreign particles. Rather than generically attack any antigens, T cells circulate until they encounter their specific antigen. As such, T cells play a critical part in immunity to foreign substances.
Dendritic cells (DCs) are professional antigen-presenting cells that link innate and adaptive immunity and are critical for the induction of protective immune responses against pathogens.They are antigen-presenting cells (also known as accessory cells) of the mammalian immune system. Their main function is to process antigen material and present it on the cell surface to the T cells of the immune system. They act as messengers between the innate and the adaptive immune systems. They produce cytokines and are susceptible to cytokine-mediated activation. Thus, interaction of resting immature DCs with TLR ligands, for example nucleic acids, or with microbes leads to a cascade of pro-inflammatory cytokines and skewing of T cell responses.
Natural killer cells is a type of immune cell that has granules (small particles) with enzymes that can kill tumor cells or cells infected with a virus. A natural killer cell is a type of white blood cell. Also called NK cell and NK-LGL.NK cells are best known for killing virally infected cells, and detecting and controlling early signs of cancer. As well as protecting against disease, specialized NK cells are also found in the placenta and may play an important role in pregnancy These cells are effector lymphocytes of the innate immune system that control several types of tumors and microbial infections by limiting their spread and subsequent tissue damage. NK cells target and kill aberrant cells, such as virally infected and tumorigenic cells. Killing is mediated by cytotoxic molecules which are stored within secretory lysosomes, a specialized exocytic organelle found in NK cells.

Pam is pregnant, and her baby already has all the genetic information needed to determine its sex, hair and eye color, skin color, and even some personality traits. What stage of development has her baby achieved?
blastocyst
zygote
embryo
fetus
Answer:
Fetus
Explanation:
A zygote, embryo, and blastocyst, are within the first few weeks for pregnancy. By weeks 7-9 the baby starts to grow arms, legs, ears, eyes, and more. And by 9 weeks, the baby's hair follicles grow, and so do the arms and legs as they grown longer. So by about week 10, you might be able to see and predict the baby's eye colour, and so forth.
Which leads up to the point that the baby is a fetus.
