Answer:
Pollination
Explanation: If you have ever seen bee movie, you know that pollen is the most essential ingredient to flowers, which is transported and spread by bee's. if there were no more bees, there would be no way to pollinate the flowers, causing them to wither and die. Fortunately, there are other pollinators, but bees are one of the most important.
Milankovitch cycle, its named for the man who theorized it
see plants are also living beings, they also need oxygen for respiration. There would be less carbon dioxide available for plants for photosynthesis. Atmosphere will be clean, less polluted, clean water. No fighting, peaceful, cool environment
Answer:
LD50 (median lethal dose)
Explanation:
- Whenever one needs to quantify the virulence of a pathogen then this is done by using a set of laboratory animals.
- LD50 (median lethal dose) is an important indicator of virulence.
- LD50 is defined as the number of pathogens that are required to kill 50% of the total infected animals.
- For the calculation of LD50, the animals are infected with a known number of pathogens and then a graph is plotted for the percentage of animals killed against the concentration of the pathogen used for infection.<em> The point at which the graph indicates the death of 50% animals, the corresponding concentration of inoculation of a pathogen is taken as the LD50 of that particular pathogen. </em>
