Answer:
The average temperature of a freshwater wetland in summer is 76 degrees Fahrenheit. The average temperature in winter is 30 degrees Fahrenheit. The climate in freshwater wetlands is usually semitropical, as freezing conditions rarely occur.
Explanation:
The most common freshwater wetland is swampland. The freshwater biome is located on every continent except for Antarctica. Most people think of it being a nuisance, but freshwater wetlands are an important part of our ecosystem. More examples of freshwater wetlands are marshes or bogs. In freshwater wetland the water will always be standing water. Most of them will have water in them all of the time, but some will only have water in them during certain parts of the year. There are 4 different seasons in freshwater wetlands. There is Summer, Fall, Winter, and Spring. The average temperature of a freshwater wetland in summer is 76 degrees Fahrenheit. The average temperature in winter is 30 degrees Fahrenheit. The average rainfall in a freshwater wetland is 59 inches or 150 centimeters to 200 inches or 500 centimeters. The freshwater wetlands get and average of 7-10 hours of sunlight a day throughout the year.
Answer:
Phototropism refers to the movement of of plant body or parts towards or away from the light. There are two types of phototropism i. e. positive phototropism and negative phototropism.
In positive phototropism, the parts of plant body moves toward light. Movements of radical in the upward direction after seed emergence is the example of positive phototropism.
In negative phototropism, the body part of plant moves away from the light. Roots are the example of negative phototropism.
Answer:
RNA polymerase binds to the promoter
Polymerase initiates RNA synthesis at the start point on the template strand
RNA polymerase moves downstream unwinding the DNA
RNA transcript is released and polymerase detaches from the DNA
The pre-RNA undergoes processing
Explanation:
The promoter is the specific DNA sequence that serves as a binding site for RNA polymerase. The enzyme RNA polymerase recognizes the promoter sequence and binds to it to begin the process of RNA synthesis. The process of RNA synthesis begins at the start site where the process of the unwinding of DNA duplex is initiated.
The unwinding separates the two DNA strands at the start site where RNA polymerase begins the process of synthesis of the new RNA strand. The newly formed RNA strand and RNA polymerase are released from the template strand after the termination of the process.
In eukaryotes, the primary RNA transcript undergoes the process of splicing of introns, the addition of poly-A tails and 5' cap which in turn transform it into the mature mRNA.

How the sea serves us
> Many of the ecosystem services provided by the sea are threatened today by overexploitation, environmental pollution and greenhouse gases. Yet in many cases, how severely individual habitats are degraded and ecosystem services are impaired is just not known. Researchers are therefore attempting to assess the exact condition of marine ecosystems. Such analysis is important in order to plan concrete protection measures and to define critical limits and target values.

The bounty of the sea
> Since time immemorial we humans have been living with the seas and from their bounty. They provide us with food, mineral resources, transportation routes and other services. The climate-regulating effect of the oceans and the biochemical processes that take place in the sea are of fundamental importance. Today, some of these services are under threat, which i
