Answer:
This exercise is incomplete, missing the value of k (decay constant), which is equal to 4x10⁻⁸s⁻¹ at 25°C
The answer is 0.549 years
Explanation:
Given:
first order of reaction
k = 4x10⁻⁸s⁻¹
For a first order of reaction, the half-life time for the degradation of DDT is equal to:
Answer:
The key difference between carbohydrates and lipids is that the carbohydrates are immediate energy sources in living organisms while the lipids act as a long-term energy resource and tend to be utilized at a slower rate. Carbohydrates and lipids are important nutrients in living organisms.
Explanation:
The three different processes that are occurring in the above drawing are:
1. Process A: Diffusion.
2. Process B: Facilitated diffusion.
3. Process C: Active transport.
Cell transport refers to the movement of ions, molecules, or substances across the cell membrane, either into or out of the cells of a living organism.
From the above diagram, the three (3) different processes that are occurring are:
1. Process A: Diffusion.
- Diffusion refers to the movement of gas molecules from a region of high concentration (top) to a region of lower concentration (bottom) until an equilibrium is attained or reached.
2. Process B: Facilitated diffusion.
- Facilitated diffusion refers to the movement of substances or gas molecules across a cell membrane from a region of high concentration (top) to a region of lower concentration (bottom), especially through the help of transport protein.
3. Process C: Active transport.
- Active transport involves the movement of substances across the cell membrane from a region of lower concentration to a region of higher concentration, against a concentration gradient and in the presence of oxygen.
