Enumerating the data points from the chart over ten years:
{100, 105, 95, 102, 93, 105, 98, 99, 101, 100}
Their initial, final, and the median values are all 100. The mean value is 99.8, and the standard deviation slightly less than 3.9. All of these statistics indicate stability of the population over the observed span of ten years. There is neither a significant growth, nor a decline. Assuming stability is what corresponds to a species doing well in a habitat, a conclusion can be made that the species is doing well!
Provided the conditions of the artificial habitat won't change significantly in the next five years, the population will continue to remain close to an average of 100, with minor deviations of +/- 4 likely year by year.
Erosion can move sediment through water, ice, or wind. Water can wash sediment, such as gravel or pebbles, down from a creek, into a river, and eventually to that river's delta. Deltas, river banks, and the bottom of waterfalls are common areas where sediment accumulates. i hope this answers your question
Answer:
4. C, B, D, A
Explanation:
This is a simple experiment to make electromagnets. Electromagnets are the instrument/object which behave like magnet when electricity is passed around them. As long as electricity is supplied they will behave like magnet. When the electricity is stopped, they will no longer behave like magnet.
The correct sequence, as per the question, to make electromagnet are listed below:
Wrap a wire to create loops around a piece of metal, such as iron. (As of now it will not behave like magnet)
As soon as we close the circuit, current starts flowing through the loops and generate magnetic field.
This magnetic field forces the magnetic domains inside metal piece to align and the metal starts behaving like a magnet.
