The two stages of photosynthesis: Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle (light-independent reactions). Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH.
Endocytosis is taking stuff in while exocytosis is getting rid of the stuff and putting it out
The answer is option 4 :3
Answer:
180seconds
Explanation:
According to the question, Kepler-186f is an exoplanet that orbits a star called kepler-186, other than the Sun.
Distance of the star (kepler-186) away from the planet is 5.4 x 10^10 meters
In order to calculate how long i.e. time, a light moving at an average speed of 3.0 x 10^8 m/s will get to the exoplanet from the star, we use;
Speed (m/s) = Distance (m) ÷ time (s)
Time = Distance/speed
Time = 5.4 x 10^10 ÷ 3.0 x 10^8
Time = 5.4/3.0 × 10^ (10-8)
Time = 1.8 × 10^2
Time = 180seconds.
