when an ecosystem changes, the results are __.
a. all positive
b. all negative
c. neither positive nor negative
d. mixed between positive and negative

pls help

Answers

Answer 1

Answer:

d). mixed between positive and negative.

Explanation:

The changes in an ecosystem bring both positive, as well as, negative consequences. On one hand, it promotes increased production of food that helped alleviate famines and poverty, enhanced resources' supply promoted economic growth and development, better assistance in dealing with climatic changes, etc. While on the other hand, the rapid changes in the ecosystem have led a number of species to migrate and many others to reach the verge of extinction. Some even have got extinct by now like dinosaurs. It has also led to a degradation of environmental resources and a reduction in biodiversity. Thus, it has both positive and negative impacts. Hence, option d is the correct answer.

How does urbanization (paving, etc.) affect runoff and infiltration in a small, previously forested drainage basin

Answers

Answer:

Run off increases and infiltration decreases

Explanation:

Urbanization usually involves activities such as paving, etc by people who moved into the area in order to make it more presentable and sophisticated. Urbanization affects runoff by increasing it because water can’t be absorbed into the paved structures so it ‘runs’ off to a place where absorption is high.

Infiltration which involves water being absorbed into the soil also decreases as a result of the pavings.

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.

rectangle is
is 4/3cm by 15/4cm. Find its
perimeter and its area.​

Answers

Answer:

Explanation:

perimeter of rectangle=2(l+w)

=2(4/3+15/4)

=2(4*4+15*3/12)

=2(16+45/12)

=2(61/12)

=122/12 cm

area of rectangle=l*w

=4/3*15/4

=60/12

=5 cm^2

Length = 4/3cm

Breadth = 15/4cm

Area of rectangle = 4/3×15/4 = 5cm²

.. Perimeter = 2(l+b) = 2(4/3+15/4)cm

= (2×61/12)cm

= 61/6cm

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?​

Answers

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.
