Answer
The worm gets coated with antibodies, which activate other cells in the immune system to secrete chemicals that kill it.
Explanation:
Production of T-helper I cytokines like IFN gamma, IL-2 and IL-18 is highly protective against helminth infection by activating the macrophage intracellular killers. Protection against mucosal eosinophil responses in which antiparasitic chemicals are released. Killing also involves direct cytotoxic mechanisms in which T- cell and NK-cells directly release antiparasitic agents like perforin and granulysin which kill the parasite.

Answer: Prophase 1
Explanation:
Nuclear division is about to occur, nucleolus disappear, fragmentation of the nuclear envelope takes place.
The centrosomes apart from each other and the spindle fiber assembles.
Crossing over may take place at this time by the end of which the sister chromatids are no longer identical.
All of these events takes place during the prophase 1 stage of meiosis.
Answer:
Wow. They're both right... I still think Vaccines aren't healthy.
Explanation:
Mitosis occurs after interphase (which is the phase that takes the longest) and is occurring all the time in your cells. Sometimes a cell will not go into a state of mitosis if an error is found during the interphase process (if it does, it's cancerous) . Some cells don't go through the process of mitosis, like neurons. But once a cell passes interphase without any errors, it will go into mitosis then cytokinesis. The process takes about one day and occurs when your body is repairing itself or if you're growing and developing. So yes, it happens all the time, just not in every single cell; just in most cells.
