Answer:
Due to the fact that the Upwelling brings all of the nutrients and food for the fish to the surface which is where all the fish will be feeding. ... Compare rivers and surface currents. Both rivers and surface currents are long, moving bodies of water.
Answer:
The resistance of the device is 27Ω
Explanation:
When a device is used in a circuit in which the voltage is 81 V, the current flowing through the device is 3 A.
In order to calculate the resistance of the device, we know that the resistance is directly proportional to the voltage in the terminals of the device and the current flowing through it.
Using Ohm's law
Ω
Answer:
40: 3
41: 1
Explanation:
40: When trying to achieve a better or sharper image on a microscope, the part of the microscope that needs to be adjusted is the "fine focus" which is responsible for better/sharper image by either moving the stage or the eyepiece. The fine focus is labelled C in the image.
41: Chromosomes contain hereditary materials (genes) that are responsible for an organism's trait. All organisms have their individual genetic materials in their cells and in the case of the onion cells, it's genetic materials (genes) are stored in the chromosomes hence it is important the cells have these chromosomes. Thus, the correct option is 1
