The dam acts as a barrier between upstream and
downstream. Dams are also built for
irrigation, but it is also deliberately destroyed in favor of irrigated
farming. Though it provides freshwater, and makes people be protected by
droughts, but it can also damage the agricultural resources by limiting the
water in some areas.
It seems that this question missed the choices which are as follows:
<span><span>A. </span></span>Positive impact of a density-dependent limiting factor<span><span /><span>B. </span></span>Positive impact of a hurricane<span><span /><span>C. </span></span>Positive impact of beavers in an ecosystem<span><span /><span>D. </span></span>Positive impacts of dams on society
The correct answer that best describes the given characteristics above which are water storage, clean energy and flood prevention is option D. Positive impacts of dams on society.
Answer:
Explanation:
1. What are negative effects of technology?
You're losing sleep or skipping physical activities due to technology use. It's causing you stress or anxiety, or you're noticing physical side effects, such as tension headaches, eye strain, muscle pain, or overuse injuries.
Positives:

When technology progresses and makes our lives even more convenient, we must stress how beneficial it is to our lives
2. Don't know
3. Decision Matrix Method. Decision matrix techniques are used to define attributes, weigh them, and appropriately sum the weighted attributes to give a relative ranking among design alternatives.
I think that since it lives on the ocean floor, at the deepest of the ocean. So anyway, the fin on the Eurypterids is still necessary but not that much, since they live on the ocean floor. Their movements mostly on the ocean floor. So fin would not help them "stick" to the floor. Also there are still gravity acts on the Eurypterids and the feet would help them move faster. Hope this helps.
Explanation: we will conclude this by the following characteristics:
1.organims that lack a proper nucleus.
2.they have membrane bounded organelles
3.they are tiny single cell oraganisms which cannot be seen by naked eye.
4.they are the oldest livinh organisms on earth
5.they are present in very harsh conditions like volcanic vents or at the bottom of the sea
