despite of many benefits, aquaculture is actually not considered a sustainable activity in the perception of the scientific community and the average population. why aquaculture is considered nonsustainable activity?
Answer:
Aquaculture has been considered as an option to cope with the world food demand. However, criticisms have arisen around aquaculture, most of them related to the destruction of ecosystems such as mangrove forest to construct aquaculture farms, as well as the environmental impacts of the effluents on the receiving ecosystems. The inherent benefits of aquaculture such as massive food production and economical profits have led the scientific community to seek for diverse strategies to minimize the negative impacts, rather than just prohibiting the activity. Aquaculture is a possible panacea, but at present is also responsible for diverse problems related with the environmental health; however the new strategies proposed during the last decade have proven that it is possible to achieve a sustainable aquaculture, but such strategies should be supported and proclaimed by the different federal environmental agencies from all countries. Additionally there is an urgent need to improve legislation and regulation for aquaculture. Only under such scenario, aquaculture will be a sustainable practice.

a divergent boundary at the
bottom of the ocean?
Answer:

A stone dropped freely from 72m height of
the tower and reaches the "ground on 6 seconds
calculate acceleration due to gravity of that stone
At what condition does the acceleration due to
gravity becomes Zero
When the initial velcity is 12 m/sec in that condition the acceleration due to gravity becomes Zero.
What is acceleration?The rate of change of velocity with respect to time is known as acceleration. According to Newton's second law, the eventual effect of all forces applied to a body is its acceleration.
The height from the stone drop,h= 72 m
t is the time period=6 sec
From Newton's second equation of motion;
[tex]\rm h = ut +\frac{1}{2} gt^2\\\\[/tex]
The condition does the acceleration due to gravity becomes Zero will be;
The gravitational acceleration is zero;
[tex]\rm h = ut +\frac{1}{2} \times 0t^2\\\\h=ut \\\\ 72 =6u \\\\ u= 12 m/sec[/tex]
Hence when the initial velcity is 12 m/sec in that condition the acceleration due to gravity becomes Zero.

The correct answer is D. Assigning representatives to control different provinces.
Explanation
Chandragupta Maurya was a Maurya leader who managed to unify much of the territory of the Indian subcontinent. During his mandate, he defeated several Greek armies motivated by the conquest of new territories in Asia. In addition, he meant an improvement in economic activities, internal and external trade, and agriculture. In the administrative aspect, he stood out for delegating governance responsibilities to representatives who controlled different provinces to provide security to the population because the size of the Empire's territory prevented him from governing from a center of power, so he had to delegate powers to avoid weakness throughout the territory. Therefore, the correct answer is D. Assigning representatives to control different provinces.

Which diagram best represents an economic problem facing Pacific South America? O A. Urban centers have grown rapidly. Populations in general are falling rapidly. ОВ Oil production has increased Indigenous people are more likely to be poor . Oc Economic growth has improved Fewer children are attending school. O Few citizens have access to education. Most countries in the region remain poor.
The diagram best representing an economic problem facing Pacific South America would be that economic growth has improved, but fewer children are attending school. This is best represented by option C.
The diagram presented by option C highlights that the economic growth doesn’t all go into educational opportunities for everyone. While the economy grows, the constant decline in school attendance shows that the economy is faced with a problem of providing access to education for the younger developing populations.

Tell whether the side lengths 3,9, and 15 form a triangle.
Answer: No, because 9 + 3 isn’t greater than 15.
Explanation:
According to the triangle inequality theorem, the sun of the 2 shorter legs of a triangle must add up and be greater than the longest side of the triangle which is the hypotenuse.
Therefore, in this case, the addition of 3 and 9 which is 12 is less than 15, therefore, the side lengths doesn't make a triangle.
