Answer:
-35 mV and +56 mV
Explanation:
The membrane potential is the energy that is needed to drive membrane changes across the phospholipid bi-layer membrane.
Ions can move in and out of the cell through protein channels. The movement of the ions is as a result of concentration that affect the operation of ion gates.
The reverse potential is given by the Nernst equation:
where, R = gas constant
T = temperature (Kelvin)
z = ion charge
F = Faraday's charge
The potential is calculated and the result is -35 mV and +56 mV respectively.
Answer:People have made art for thousands of years. Some of the earliest art comes from the Stone Age, a time period during which early humans first made and used simple stone tools. Scholars divide the Stone Age into three spans of time: the Paleolithic (the word literally means old stone age), which runs from 2,500,000 to 10,000 BC; the Mesolithic, from 10,000 - 4000 BC; and the Neolithic, from 4000 - 2000 BC. In each period, the tools became a little more complex. The art from this time is also sometimes also called prehistoric art, because it was made before recorded history.
The people who created Stone Age art relied on natural materials they found in their environment. They used all types of stone and also mammoth ivory, animal bones and antler out of which they carved small figurines. They painted on cave walls, using clay ochres and iron oxide for yellows and reds, and manganese oxide and charcoal (burnt wood) for black. Think of the first ancient painters. How did they figure out what substances left the best mark? Stone Age art is an interesting glimpse into the ingenuity of early humans.
Explanation:
Answer: Emigrant
Explanation:
A person that leaves their country of origin is referred to as an emigrant. An emigrant moves to another country in order to seek better living standard.
People also move abroad for educational purposes, due to marriage or due to economic opportunities. For example, Africans moved to developed countries in order to seek better opportunities.
