Answer:
231 ml
Explanation:
Let x represent the amo unt of Dextrose 70% in ml and y represent the amount of Dextrose 5% in ml needed to prepare 1,000mL of Dextrose 20%.
Since 1000 ml of Dextrose 20% is needed, hence:
x + y = 1000 (1)
Also 70% Dextrose is mixed with 5% dextrose to produce 20% dextrose. i.e.:
70% of x + 5% of y = 20% of 1000
0.7x + 0.05y = 200 (2)
We have to solve equations 1 and 2 simultaneously.
Let us multiply equation 2 by 20:
14x + y = 4000 (3)
subtract equation 1 from 3:
13x = 3000
x = 231 ml
Put x = 231 in equation 1 to find y:
231 + y = 1000
y = 769 ml
Therefore 231 ml of Dextrose 70% must be mixed with 769 ml of Dextrose 5% to prepare 1,000mL of Dextrose 20%? *
Answer:
The cerebral cortex is the answer. A.
Explanation:
The Academy of Nutrition and Dietetics (Academy) is the largest association of qualified nutrition and dietetics practitioners, including registered dietitian nutritionists (RDNs), nutrition and dietetic technologists, and registered dietitians (NDTRs).
RDNs combine research, professional growth, and practice to promote innovation and discovery, work with others to address today's and tomorrow's most pressing food and nutrition issues, concentrate on systemic effects across the food, wellness, and health sectors, have a global impact on the eradication of all forms of malnutrition, and strengthen the role of nutrition and dietetics practitioners while increasing workforce capacity and capability. The minimal competent level of nutrition and dietetics practice and professional performance for RDNs is reflected in these standards.
