Answer:
180seconds
Explanation:
From 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
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 the following formula;
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.
Answer:
Oxygen
Explanation:
Trees and plants that have chlorophyll take in carbon dioxide from the air and combine it with water in a series of photosynthetic processes to make food for the plants. This is important in not only removing the excess carbon dioxide that is in the air but in also providing oxygen to animals.

Answer:
Endosymbiotic theory explains that at a certain point of evolution both mitochondria and chloroplast (cyano bacteria) existed independently as prokaryotic organisms. Which were "engulfed" by eukaryotic cells but instead of being consumed a symbiotic association was developed between the cells, which over various stages of evolution became components / organelles of the eukaryotic cell due to migration of some prokaryotic genes to the eukaryotic nucleus. However, they retained their capacity of duplication due to presence of circular DNA
So, the correct answer is'The mitochondria and chloroplast have their own DNA'
