**Bioreactor Feeding Rate Analysis**

The graph illustrates the feeding rate (R) in grams per hour \(\left[\frac{g}{h}\right]\) as a function of time (t) in hours \([h]\) for a bioreactor.

**Graph Details:**

- **X-axis:** Represents time in hours ranging from 0 to 14.
- **Y-axis:** Represents the feeding rate in grams per hour ranging from 0 to 6.

**Data Points:**

- At hour 0, the feeding rate starts at 1 g/h (Point A).
- The rate increases to 2 g/h at hour 2 (Point B).
- At hour 4, the rate reaches 3 g/h (Point C).
- Between hours 4 and 6, the rate maintains at 3 g/h (Point D).
- At hour 6, the rate decreases to 2 g/h (Point E).
- From hour 6 to 7, the rate remains constant (Point F).
- Between hours 7 and 8, the rate jumps to 5 g/h (Point G) and remains through hour 10 (Point H).
- The rate then decreases sharply to 0 g/h at hour 14 (Point I).

**Interactive Questions:**

1. **Select the phrase that makes the following sentences true:**
   - Between points C and D, the feeding rate [Select].
   - Between points D and E, the feeding rate [Select].

2. **Calculate Mass Added:**
   - The mass of feed in grams added to the bioreactor between points F and G is [Select] grams \([g]\).
   - The mass of feed added to the bioreactor between points E and F is zero.
   - The mass of feed added to the bioreactor between points H and I is [Select].

This exercise is designed to help understand the changes in feeding rate over time in a bioreactor system.
