Winter weasels, also called ermines or short-tailed weasels, have coats that turn from light brown to white in the winter. The color change begins at their stomachs and works its way outward, occurring in both spring and fall. Other species, like the long-tailed weasel, may turn at least partially white as well.
The length of daylight, not temperature, prompts the color change. As a result, weasels in winter may be stark white against a brown landscape before snow starts to fall. During warmer winters, this makes them easy prey for larger predators such as foxes, martens, and badgers.
Answer:
current, voltage
Explanation:
Resistors can both be connected in series and parallel configuration. when a resistor is connected serially, the same amount of current flows through each resistor element but the voltage across each resistor is determined by the magnitude of the resistance of each resistor. However, in a parallel connection, the same voltage is applied across each resistor but different current.
The vacuole, its main job is to get rid of waste and water inside the cell.
Answer:
Yes
Explanation:
The velocity measured by Jennifer and Johnny is
The actual velocity is
We can calculate the % error of the students measurement as follows:
Which is lower than the 2.5% maximum error required, so the two students will pass the test.
