Answer:
increase in water vapor and decrease in energy leaving the planet and increase in temperatures.
Explanation:
This is just what I think I might be wrong though.
Answer:
a change to precipitation
Dendrites and axons.
Dendrites and axons are extensions/fibers in nerve cells that either recive or send information to neurons respectively.
→ The image below shows you both and more parts of a nerve cell.

Answer:
Speciation is an evolutionary process by which a new species comes into being. A species is a group of organisms that can reproduce with one another to produce fertile offspring and is reproductively isolated from other organisms. Speciation can be driven by evolution, which is a process that results in the accumulation of many small genetic changes called mutations in a population over a long period of time. There are a number of different mechanisms that may drive speciation. One of these is natural selection, which is a process that increases the frequency of advantageous gene variants, called alleles, in a population. Natural selection can result in organisms that are more likely to survive and reproduce and may eventually lead to speciation. A second process called genetic drift describes random fluctuations in allele frequencies in populations, which can eventually cause a population of organisms to be genetically distinct from its original population and result in the formation of a new species.
Explanation:
1. Once a dam is constructed, electricity can be produced at a constant rate.
<span>2. If electricity is not needed, the sluice gates can be shut, stopping electricity generation. The water can be saved for use another time when electricity demand is high. </span>
<span>3. Dams are designed to last many decades and so can contribute to the generation of electricity for many years / decades. </span>
<span>4. The lake that forms behind the dam can be used for water sports and leisure / pleasure activities. Often large dams become tourist attractions in their own right. </span><span> </span>
<span>5. The build up of water in the lake means that energy can be stored until needed, when the water is released to produce electricity.
6</span><span>. When in use, electricity produced by dam systems do not produce green house gases. They do not pollute the atmosphere </span>
<span>DISADVANATGES: </span>
<span>1. Dams are extremely expensive to build and must be built to a very high</span>
<span>2. The high cost of dam construction means that they must operate for many decades to become profitable. </span>
<span>3. The flooding of large areas of land means that the natural environment is destroyed. </span>
<span>4. People living in villages and towns that are in the valley to be flooded, must move out. This means that they lose their farms and businesses. In some countries, people are forcibly removed so that hydro-power schemes can go ahead. </span>
<span>5. Although modern planning and design of dams is good, in the past old dams have been known to be breached (the dam gives under the weight of water in the lake). This has led to deaths and flooding. </span>
<span>6. Dams built blocking the progress of a river in one country usually means that the water supply from the same river in the following country is out of their control. This can lead to serious problems between neighbouring countries. </span>
<span>7 Building a large dam alters the natural water table level. For example, the building of the Aswan Dam in Egypt has altered the level of the water table. This is slowly leading to damage of many of its ancient monuments as salts and destructive minerals are deposited in the stone work from ‘rising damp’ caused by the changing water table level.</span>
