First comes fertilization, when two gametes combine to form a zygote.
Meter is the SI unit for length. :)
Normal, clean rain has a pH value of between 5.0 and 5.5, which is slightly acidic. However, when rain combines with sulfur dioxide or nitrogen oxides—produced from power plants and automobiles—the rain becomes much more acidic. Typical acid rain has a pH value of 4.0.
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.
Answer:
<em>The correct option is D) need to be aware that if any of his garlic plants became diseased, it could very likely infect the entire crop</em>
Explanation:
If cloves from a bulb are taken and grown, then the plants formed will be identical to each other. As a result, there will be no genetic varieties in the garlic plants being produced. Hence, when a diseases eradicates, it will affect the entire plants of the garden as they would be genetically identically, Variations would have allowed some of the plants to be resistant for the disease and hence some of the plant species could be saved by genetic variations.
