A fuel cell works like a battery. It consists of two electrodes where the reactions would occur and an electrolyte solution which allows for caharged particles to flow. In a fuel cell that uses hydrogen and oxygen as reactants. The hydrogen would enter the cell at the anode where oxidation would happen. So that the species that is formed in the anode side would be hydronium ions and electrons. The oxygen, on the other hand, would enter the cathode electrode where reduction occurs. The species that are produced in this side of the cell are water molecules. Together, the net reaction is called a redox reaction.
Hypothesis: If Plant Food X is used on a tomato plant, then production rate will increase.
experiment: Gather 2 tomato plants of the same height and age. Make two groups, a control group (a tomato plant without use of fertilizer) and an experimental group (a tomato plant with using Plant Food X).
For one week, give each plant the same amount of water, humidity, sunlight, and air temperature. after a week measure the height and number of tomatoes produced. gather the info in a table and compare to hypothesis after one week.
Answer: herbivore, eukaryote, primary consumer
Explanation:
The red squirrel can be described by the following features.
1. Herbivore: A herbivore is an animal which is dependent upon the plant and their products for it's food requirement. Here, the red squirrel is the herbivore because it is dependent upon the spruce tree seeds for their food requirement.
2. Eukaryote: A eukaryotic organism is the one which has well define nucleus and encloses the genetic material in the nucleus. The red squirrel is a complex eukaryotic organism.
3. Primary consumer: In a food chain a primary consumer is an organism which is dependent upon plants and their food products for energy and food needs. The red squirrel is the primary consumer this is because of the fact that it consumes on the seeds of the spruce trees.
Answer:
Spotted Eagle Rays have two sets of five gills on each side of their body on the ventral side. In order to breathe, A. narinari must be in continuous swimming motion so that oxygen can be absorbed from the water passing through the gills
