The amount of available resources in the ecosystem must change at a predictable rate.
1. outer covering - none of the other answers can occur due to the absorbed solutions inability to reach the centre of the organism, smaller cells in greater numbers are more efficient as they can group together yet all absorb the right amounts of nutrients for its need. multi cellular organisms, such as humans can have the other answers in them as cells group together to make skin, muscles and organs. it also gives the organism to grow larger.
2. bacteria are single celled. bacteria reproduce through mitosis (cell division). bacteria break down decaying matter to obtain energy. every organism requires energy to live. Bacteria can move in order to reach their nutrient source.
Answer: If the Euglena is kept on the wet mount and it is sliding towards the left on the mount then to observe the Euglena in the microscope it wet mount should be slide towards right.
The movement of Euglena can be slowed down doing this. This will help us to observe it under microscope inspite of its movement.
Compound microscope is used to view Euglena.
