The motivation behind why there is a green layer of green growth was on the grounds that that there might be an excess of fertilizers connected in the garden. When having an excess of manure, and it had been poured down, there could have been a probability of run-off to be flown down on the garden. By this, it builds the supplements in the lake, making the green growth to develop on it.  

Further Explanation:  

Fertilizer:

A fertilizer or manure is any material of normal or engineered beginning that is connected to soils or to plant tissues to supply at least one plant supplements basic to the development of plants. Numerous wellsprings of manure exist, both common and modernly created.  

Fertilizer Types:  

1. Nitrogenous Fertilizers  

2. Natural Nitrogenous Fertilizers  

3. Phosphate Fertilizers  

4. Potassic Fertilizers  

5. Compound Fertilizers  

6. Complete Fertilizer (NPK)  

uses of Fertilizers:  

Nursery workers and business producers use manures. At the point when utilized properly, fertilizer can improve soil surface, advance sound development, and increment yields.  

Importance of fertilizers:

Fertilizers are substances containing concoction components, for example, fertilizer or blend of nitrates that improves the development of plants. They offer sustenance to the harvests. At the point when added to soil or water, plants can create resilience against vermin like weeds, creepy crawlies and sicknesses.

The reason why there is a green layer of algae was because of the reason that there may be too much fertilizer applied in the lawn. When having too much fertilizer, and it had been rained down—there could have been a possibility of run-off to be flown down on the lawn of which has been sloped and made its way on the pond. By this, it increases the nutrients in the pond, making the algae to grow on it.

How does the gradient change the velocity of the water?
vlada-n [284]

The velocity of a stream usually increases downstream. The gradient (slope) of the stream typically decreases but gravity, elimination of bed roughness and an increase in the amount of water from the entry of tributaries tends to increase the velocity.

PLEASE HELP!!! ASAP 30 POINTS!!

Darwin’s research showed that finches beaks are different to fit their food source. It also started the theories of evolution and natural selection. The Grant’s research on the Galapagos Islands showed that evolution exists and can happen over a course of two years. They proved Darwin’s theories are true. Since all the plants and animals are native to the islands, they had to adapt to the new food source and climate. Beaks, size, etc. are all changes made to these organisms to be able to live on the islands. 

The Galapagos Islands are located in Ecuador and sit on the Pacific Ocean. <span>The Galapagos Islands were formed from 3 million to 5 million years ago. Volcanic eruptions typically shield volcanoes formed the islands. They are located over a “particularly hot mantel” that causes volcanic activity. The outcome of many eruptions were islands because the left overs were pushed to the surface. The Galapagos islands are pretty big reaching an area of 3,093 miles. The temperatures range from 69 to 84 degrees creating a typically warm climate. </span>

Darwin studied medicine at age 16, but became fascinated specimens around the globe. He developed theories of natural selection and evolution. While he was on the Galapagos islands, he studied thirteen different species of finches.

 He observed finches and different beak structures. He observed their ability to consume foods such as nuts, bugs, and fruit. He concluded all were related to their beaks. For example, long, slender beaks are good to reach in the flowers of a cactus.

<span>Charles concluded that the finches beaks are examples of adaptive radiation. To fit in the island, they had to adapt to the conditions. This lead to Charles’ theory of natural selection. </span>

Charles came to the conclusion of evolution and natural selection. Natural selection is the process where organisms adapt to their environment to survive and produce more offspring. Evolution is where different kinds of living organisms are thought to have developed. These theories have changed science forever and leave today’s scientists marveling of his theories.
