To build a complete picture of the animals and plants that were living at a particular time in the past. ... In addition, the rock itself provides much useful information about the environment in which it and the fossils were formed.
A monosomy occurs when a zygote has a single chromosome missing in each cell. This happens when<span> a portion of the chromosome has one copy while there are two copies in the rest of the other chromosomes.An example of an disorder is the Turner Syndrome which has only 1 X chromosome in female genome.</span>
The organelle that maintains pressure against the cell wall, so that the plant cell keeps it shape, is
the (a) central vacuole.
Answer:Increase in ambient global temperatures.
Recyling energy to be used again
Regulation of oxygen and carbon dioxide levels
An increase of erosion and siltation along waterways
Explanation:
Conservational biologists think about the preservation of ecosystem by maintaining the environment in a human control way.
Increase in ambient global temperatures.: The humans must prevent the increase in global temperature worldwide by preventing the rise of greenhouse gases which can lead to global warming worldwide.
Recyling energy to be used again: The sources of energy like wood, waste water can be recycled again for reutilization.
Regulation of oxygen and carbon dioxide levels.: The oxygen and carbon dioxide levels must be regulated. As oxygen is the basic requirement for respiration. The increase in carbon dioxide levels due to human activities is likely to cause respiratory diseases and health hazards in living beings.
An increase of erosion and siltation along waterways.: The erosion and siltation will likely to deposit nutrients and debris which may either contaminate the waterway or may cause eutrophication.
