Read the passage “ a river for everyone”, then answer two questions below.( the entire passage is in the image above)
Anna007 [38]

Answer:

1. Moving the facilities such as crops, lawns, golf courses, and sewers etc would be unrealistic to change because many of the owners would not comprise (costs so much already), yet there are solutions. For example, the town can restrict farmers from poluting the rivers with pesticides as well as fining them and the house developments golf courses and land owners in which the money can be used towards the filteration cost. Another idea would to build cheaper wells to soak up water from different river locations or build barriers around settlements from the river. Another idea would to simply grow natural filters such as using the trees and soil they already had.

2. Of course their are limits such as costs, and figuring out the landscapes of where to build wells, add soil and trees (trees take time to grow) and more that would need plan of action from community leaders in which the people would need to speak with the advisors or the management of the buildings nearby. Without clean water people will get sick or die, and building managers need healthy people to live in their houses and work and grow crops so they'll have to make change.

what theory states that not only climate but several other factors determine the characteristics of the climax community
shusha [124]
<h3><u>Answer;</u></h3>

Climax-Pattern Theory

<h3><u>Explanation;</u></h3>
  • The Climax Pattern Theory emphasizes that a natural community is adapted to the whole pattern of environmental factors in which it exists.  
  • In addition to climatic factors, e.g. wind, there are a whole range of edaphic factors, fire, and biotic factors, including grazing, disease and mutualistic and competitive interactions.
  • The Climax Pattern Theory allows a continuity of climax types, varying gradually along environmental gradients and not neatly packaged into discrete climax types.

A scientist used radiation to change the mutation rates of a population of bugs. He then measured how many generations it took f
Papessa [141]

For this experiment, artificial selection is made by the scientists where traits of benefit are made to be present in the gene by high mutation rate so that the adaptability increases.

Explanation:

Natural selection is a process by which a organism with beneficial traits survive and reproduce in large numbers. They adapt to the environment very quickly and pass on these traits to its progeny which are at the better survival zone.

The mutations for the beneficial traits in certain genes caused the bugs to adapt to their environment well. When mated, they pass on the traits in every generation. It is also said that those organisms who did not get mutated eventually died.

The faster the mutation rate, the faster the mutated bugs with beneficial traits will appear in each generation.

From the graph it can be said that those bugs who could not bear the mutation they died and hence did not appear in the next generation only those bugs who could cope up the environment survived.
