Complete Question
Ruben Ward has been weight lifting and eating a high protein diet. Below is Ruben's profile and what he ate for a day. He entered his profile information and food intake into Diet & Wellness Plus and then pulled the Diet & Wellness Plus Reports. View Ruben’s Intake vs Goals and Macronutrient Ranges Reports and then answer the questions below. Profile for Ruben Ward 1. Age: 19 years old 2. Gender: Male 3. Height: 5 ft, 8 inches 4. Weight: 205 lbs 5. Non-Smoker 6. Activity Level: Active
Ruben has recently taken up weight lifting, and his friends at the gym mistakenly believe they should eat more protein to build muscle. The DRI for protein for healthy adults is 0.8 g per kg body weight. If Ruben weighs 205 lbs (93 kg), how many grams protein per kg body weight did he eat on this day?
a. 5.37 g/kg
b. 10.33 g/kg
c. 3.55 g/kg
d. 4.88 g/kg
Answer:
c. 3.55g/kg
Explanation:
RDI means Recommended Dietary intake. It is the required amount of a nutrient expected to be taken by an individual for optimal health.
The Recommended Dietary Intake I'd protein falls withing the range of 0.8 grams per kg to 1.8 grams per kg
For Reuben
He weighs 93 kg
If Reuben consumed 330 grams of protein, his grams of protein per kg body weight is
330 grams ÷ 93kg
= 3.55g/kg.
Answer:
The water molecules in ice are considerably far apart as compared to cold water of 4 degrees centigrade and below. This, therefore, makes ice less dense than water at these temperatures (because they are fewer water molecules in ice per unit volume). This is why ice floats on cold water below 4 degrees centigrade. Ice, being a bad conductor of heat, shields the water below an ice sheet from excessive heat loss to the atmosphere. This is why water remains liquid below an ice sheet protecting the marine life below from complete freezing.

Answer:
(B) Energy transfer between trophic levels is almost always less than 20% efficient.
Explanation:
The ultimate source of energy on the Earth is the Sun. The energy coming from the Sun is captured by green plants by the photosynthesis. During photosynthesis sun energy is fixed into chemical energy (carbohydrate). So, in an ecosystem energy flow is unidirectional (from sun to the green plants). The fixed chemical energy from green plants is transferred to the herbivores then to carnivores through food. When one organism eats another organisms, only 10 % of the energy present in the organism is transferred as a food for the next organism and a large amount of energy is lost as heat into the environment. Thus, energy keeps on decreasing when stored energy moves from producers to top consumers. Thus, less than 20% energy transfer limits the trophic levels in most of the ecosystem.
