Hello how are you?
The answer is B
Answer:
Explanation:
Dhiki (Nepali : ढिकी [ɖʱiki]), Dhinki or ढिँकि in Odia, is a traditional Nepalese rice (millet etc.) beater used in villages. In Odia,it is called Dhinki ଢିଙ୍କି. The manual wooden thresher 'Dhiki' is made of wood and works like a lever, but is instead used for grinding. The framework consists of a fulcrum having two pillars on each side, an effort area (where one person stands on the long thick plank of wood making effort at every interval), a long and thick plank of horizontal wood which has a small vertical extension that goes into a hole made in the ground. It is in this hole that the grains or dry chillies are kept to transform them into powder. the person using this usually places his/her leg on one side and press it hard and then leave it so that the other part hits the rice, millet, etc. and grinds it. It works like the see-saw i.e. when one part's up the other one's down and vice versa. It is a local technology used in nepali villages. When, rice mill was not used, this Dhinki used to dehusk the rice, make various powders like rice powder, masala powder etc. The dehusked rice was very healthy as it was not polished. The device required two persons. One to push the log upward by foot pressing of the lever downward and the second person rotate the rice load for uniform pounding.
Answer: I would say that it can be a an example of counterculture since it shows different points of view according to different cultural standards.
Explanation:
Scholars such as Joanne Martin and Caren Siehl, deem counterculture and cultural development as "a balancing act, [that] some core values of a counterculture should present a direct challenge to the core values of a dominant culture". Therefore, a prevalent culture and a counterculture should coexist in an uneasy symbiosis, holding opposite positions on valuable issues that are essentially important to each of them. According to this theory, a counterculture can contribute a plethora of useful functions for the prevalent culture, such as "articulating the foundations between appropriate and inappropriate behavior and providing a safe haven for the development of innovative ideas".
When a person has previously been vaccinated against a viral pathogen, then Memory cytotoxic T cells are activated if that same pathogen re-enters the host's cells months or years later.
Memory T cells are antigen-specific T cells that persist long after the infection has cleared. Memory T cells are rapidly converted into large numbers of effector T cells upon re-exposure to specific invading antigens, providing rapid responses to previous infections. Memory T cells are either CD4+ or virus-specific CD8+ depending on the type of antigen encountered. Memory T cells include subtypes of central memory T cells (Tcm cells) and effector memory T cells (Tem and Temra cells) (Willinger et al., 2005). They also normally express the cell surface protein CD45RO (Valentine et al., 2013; Akbar et al., 1988).
Memory T cells play a central role in modulating antigen-specific recall responses in vivo. Compared with naïve T cells, memory T cells respond faster to the cognate peptide: MHC, with a shorter lag time in cell cycle entry and exertion of effector functions.
