b. At higher elevations, it would take longer to hard boil an egg, because there is a lower boiling point,  so the egg is boiling in water at a lower temperature.
Explanation:
The best answer from the given choices is that, at higher elevations, it would take longer to hard boil an egg, because there is a lower boiling point,
so the egg is boiling in water at a lower temperature.
- Boiling point is simply the pressure at which the vapor pressure of a liquid is equal to the atmospheric pressure. 
- At higher elevations, the atmospheric pressure is low and it would require little heat to boil water and turn it into vapor. 
- To hard boil an egg, we need elevated temperature. 
- But since water to use hard boiling has an unusually low temperature, it becomes more difficult since much of the water turns into vapor. 
- This is why at higher elevations, it takes a longer time to hard boil eggs.

Answer:
Side = 10 cm, side = 5 cm, side = 6 cm
Explanation:
Triangle is made up of three line segment. Three line segment can form a triangle only when sum of two small line segment is more than the third line segment.
a. Side = 10 cm, side = 5 cm, side = 6 cm
5 cm + 6 cm  = 11 cm > 10cm
In the first option, the sum of two small sides is more than the third size, hence it will form a triangle.
Other options do not fulfil the same criteria, so they will not form a triangle.
Hence, the correct answer is "Side = 10 cm, side = 5 cm, side = 6 cm".
 
        
             
        
        
        
Answer:
Photosynthesis and Organisms respiration
Explanation:
Carbon exchange is known as the Carbon cycle, In this cycle, the biosphere and the atmosphere are in constant interaction because of the different organisms that use carbon in some way. Plants are able to capture the CO2 of the atmosphere and transform the carbon to energy and oxygen through Photosynthesis. Also, plants liberate the Glucose produced in Photosynthesis to stimulate plant growth through a process called Plant respiration.
Photosynthesis exchanges about 120 gigatons of carbon per year and with plant respiration´s 60 gigatons of carbon per year they are the two largest exchange processes between biosphere and atmosphere.
