The eye spot and the chloroplasts work together to help the euglena survive because the eye spot senses the light and the dark. Since euglena need to do photosynthesis in which uses light energy to make usable energy, to get food, the eye spot will tell the euglena where to move in order for it to be able to do photosynthesis.
Answer:
The mechanism is natural selection.
Explanation:
Natural selection is the mechanism that these air-breathing fishes have gone through to survive. This mechanism allows species to survive and reproduce due to differences in the phenotypes of every individual in the specie, throughout the time the heritable traits that every individual inherits changes according to the environment and the characteristics of its ancestors.
Answer:
The H+ ions moves outside.
Explanation:
The H+ ions moves outside the mitochondria of the cell if the concentration of H ions were higher inside the mitochondrion than outside environment of the mitochondrion in order to equalize the pH or H+ ions concentration of both inner side of mitochondria and outer side environment. This movement of H+ ions from a region of higher concentration to the region of lower through a semi-permeable membrane is known as osmosis which has a positive effect on the cell as well as organelles of the cell.
