Answer:
Approximately 5.2 colonies
Explanation:
Given that the original broth culture has 52 million bacteria/ml. = 52 * 10^6 bacteria/ml
It is diluted 100 times in bottle A = 52 * 10^4 bacteria/ml
It is diluted 100 times again in bottle B = 52 * 10^2 bacteria/ml
It is diluted 100 times again in bottle C = 52 bacteria/ml
From bottle C, 0.1 ml is plated = 5.2 bacteria
Since a single colony on plate represents a single bacteria in solution, approximately 5.2 colonies will be observed on plate.
1. Intentionally taking species over to another place. Think smuggling animals over, you might think a squirrel is cute and bring it home from your trip to Paris back to the US. That squirrel can now be an invasive species. Don't be spiderman and take a banana on the plane!
2. Unintentionally carrying a species over. This can be on boat propellers, water tanks in boats, airplane wheels, etc. Getting animals stuck in transportation can become invasive.
Answer:
Explanation:
the nucleus , it contain chromatin reticulum which later forms the DNA
Answer:
When animals eat their food combine with oxygen, which produces energy for the animals to use for everyday activity and then gives off carbon. The carbon then combines with the oxygen to form carbon dioxide, which is then released back into the atmosphere as waste product when the animals breath.
Carbon Dioxide (CO2)
Hope this helps ;)
