Answer:
The correct answer is "resolution".
Explanation:
The resolution is one key feature that a microscope must have in order to differentiate among microscopic structures that are very close to each other. Resolution is defined as the shortest distance between two points that can be distinguished as two separate structures under the microscope. Therefore, the ability to distinguish two objects separated by a small distance is called resolution.
I think the answer would be down
So given the suggested food chain of algae-snail-sunfish-heron we can conclude that this food chain is heavily dependent on the process of photosynthesis.
The algae is the only of the organism that are directly dependent of the photosynthesis for their survival, while the snail, sunfish, and heron, and indirectly dependent on it.
Since we are talking about a food chain, in essence it means that all organism are connected through one another. So the algae perform photosynthesis for its own survival, the snail is using the algae is a food source, the snail is later eaten by the sunfish, and the sunfish goes on the menu of the heron.
If the algae, by some scenario, are not able to perform photosynthesis, than they will die off, and if they die off, than the snail will die off because of lack of food, if the snail dies off, along with it dies off the sunfish because of lack of food, and if the sunfish is out of the scene, the heron goes as well.
So we can conclude that the process of photosynthesis is of crucial importance for the survival of all four species, be it directly or indirectly.
Answer:
C. Plants must be able to increase their mass using substances in addition to what is found in soil
Explanation:
The plant increased its mass by 74.4 kg, and the mass of the soil decreased only by 54 g (less than 0.1 % the mass of the plant).
The plant must have gotten its mass from someplace other than the soil.
A is wrong. The plant gets its mass from someplace else.
B is wrong. Plants don't need soil as such, but they need the water that is in the soil.
D is wrong. The water contains no food. It is just water.
E is wrong. The experiment demonstrated nothing about oxygen.
