Two sustainability challenges you would face when developing a sustainable food supply for a Martian colony would relate to Martian radiation and soil characteristics.
According to experiments carried out, Martian radiation is about 17 times more intense than on Earth, which impacts vegetation growth and crop quality.
Therefore, it is necessary to develop resources that enable a sustainable food supply in remote locations, such as for a Martian colony, as some production challenges may be related to food resistance and the amount of oxygen and water needed for growth.
Some solutions, therefore, could be planting in an underground shelter, which would be a controlled environment where conditions would be more favorable for the production of food with greater quality and diversity.

Answer:
d) 1000 times
Explanation:
As we know that difference of sound level is given as
so here we need to find the ratio of two intensity
it is given as
now we have
so it is
d) 1000 times
Answer:
he maximum frequency occurs when the denominator is minimum
f’= f₀ 
Explanation:
This is a doppler effect exercise, where the sound source is moving
f = fo 
when the source moves towards the observer
f ’=f_o 
Alexandrian source of the observer
the maximum frequency occurs when the denominator is minimum, for both it is the point of maximum approach of the two objects
f’= f₀
It might be c I'm not sure either. Hope I helped
