Answer:
Thymosin
Explanation:
Thymosin is the term used to refer to a set of thymus polypeptide hormones that influence the maturation of T lymphocytes intended to play an active role in cell mediated immunity. Thymosin may serve as an immunotransmitter by modulating the hypothalamic-pituitary-adrenal and gonadal axes. It also helps to counteract the harmful effects of cortisol.
Answer and explanation:
Fungi and protists are eukaryotic. However, antibiotics selectively targets prokaryotic cells. Thus, the use of antibiotics for the treatment of fungal and protist infection is of no use at the first place. Secondly, if we use the other medicines that could kill the fungi/protists (e.g. fungicides), they could also kill the host's cells (animal's cells). This become further difficult if the infection is deeper in the skin. This is because, we would not be able to apply the medicine as direct application on skin but would give either intravenous or via food. This would increase the chance of imacting negatively the other organs/cells. The only option in such scenario is the surgery, which cannot be 100% effective because some spores may left even after the treatment.
Frequency is the term that describes the number of waves passing a point during a certain period of time, frequency is also measured in Hz (hertz).
Well, an endoskeleton is an internal skeleton, like humans have.
Pro: Bones do not get broke as easily, since they are inside of the body. Bones that break also heal more quickly in an endoskeleton, since they have tissue and blood surrounding it and transferring nutrients.
Con: The flesh can get easily damaged. There is no shedding with endoskeletons, so a new skeleton cannot be grown in the event of an injury.
