Externally, rats have skin, fur, tails, feet, whiskers, eyes, noses and ears. Internally they have all the same internal organs as a person does.
Does a cell with 12V store more energy than a cell with 1.5V?
It might but not necessarily.
The amount of energy (Joules) is the voltage (volts), times the current (amps), times the time in seconds.
If the 1.5 volt battery can produce 8 times as much current for the same time, it contains the same amount of energy as the 12 v battery.
But if you take 8 cells and put them in series to produce 12 volts, you will get 8 times the total energy.yy.
Also, if you put 8 cells in parallel you will get 8 times the energy.
Is the human population in hardy Weinberg equilibrium?
The human population is not in Hardy-Weinberg equilibrium.
The Hardy-Weinberg theorem is an ideal principle in which the population of a species will remain constant only if the following five assumptions are true: 1 - random mating, 2- a large population size, 3 - no mutations, 4- no new alleles are introduced/lost, and 5 - no natural selection. If all of these assumptions are correct, then the population is in genetic balance, Hardy-Weinberg equilibrium; however, this is only an ideal situation because evolution is always occurring within populations.
Humans, for example, do not randomly mate: usually individuals choose a spouse who has positive attributes that they like, which may include: personality, taste, attractive, good with children, intelligence, sometimes race/color, sometimes height, humor, etc. So we have now disproved #1.
#3 - every human being, according to my Biology professor Donald Chandler, has at least 2 mutations. Most mutations are not harmful or don't make any real difference. Some can be very harmful; the point is that humans have mutations and thus #3 is broken.
#4 - New alleles are being introduced into the human gene pool from other human populations constantly - no one stays in their town and inbreeds with only their neighbors. We travel/marry people from other streets, towns, cities, states, countries, or at least our entire family is not made up of second cousins twice removed. Thus #4 has now been disproved as well.
#5 - natural selection occurs all of the time - People who carry inherited, life-threatening diseases may die before they can pass the gene for that disease to their offspring. With the help of modern medicine, this is now not as terrible as it used to be. People can be treated with proper medications for their genetic diseases. Women who in the 1800s would have died in childbirth due to being too small in the hip area to give birth can now have Caesarean sections (C-sections) and both mother and child can survive. Without modern medicine, natural selection would have been genetically in favor of women with larger hip areas for childbirth.
I skipped #2 because although there are billions and billions of humans in the world, I was not sure if an ideal population should have an infinite number of individuals. Either way, now you know all about how this Hardy-Weinberg theorem works - and how the ideal situation could never truly occur, even in Humans.
How many seasons are in Louisiana?
Louisiana has four seasons, just as the rest of the states do. While fall and winter seasons of Louisiana are not usually as cold as those of the more northern states, they are still separate, definitive seasons.
How have mountain passes been helpful to India since historic times?
The mountain passes namely Khyber and Bolan helped foreigners to invade India especially the Persians.
What are some important people and events in Afghanistan?
A person who has lived there in the past is Alexander The Great.
And important event is they gained their independence on August 19, 1919 and they wrote their constitution on January 4, 2004
How would you describe New York City with the 5 themes of geography?
how would an average American describe nyc
The five themes are location, place, human-environment interaction, movement, regions
Location
Located on the west coast of the north American continent and having a temperate climate. Located at 40 degrees north , 70 degrees west.
Place
Originally located on an island (Manhattan) at the mouth of the Hudson river.
Human-environment interaction.
Manhattan is now completely built over and the town has spilled over to neighbouring banks and neighbouring Long Island. Bridges go from Manhattan to the surrounding suburbs. The population of the conurbation has grown to 18 million.
Movement
The town grew from nothing by successive waves of immigration, originally from the Netherlands, but also from England, Ireland, Italy and the Jewish diaspora. A large number of black Afro-Americans also moved there.
Good communications with the Old World via the Atlantic and with Canada and the Great Lakes via north-south valleys.
Region
New York is a city, administrative divided into five counties.
What is it called when you have a old memory of what's happening at the present time?
Deja Vu (seen before)
Does the temperature affect how long the bubble lasts?
Actually it does. If you put the bubble solution in a freezer or Antarctica or something like that, and you blow it in the air then it will sink slower to the ground.Besides, bubbles pop because the soapy film around it evaporates if it's not connected to liquid or anything like that.So in the cold, you halfway freeze up the soapy film around the bubble.That way it stays in the air slower.And in the warm solution, the bubble sinks more quicly to the ground, I haven't figured out that yet.So yes temperature does affect how long the bubbles stay in the air.
Why are there so many orphans in Haiti?
There are many factors contributing to the high number of orphans in Haiti, including poverty, the impact of natural disasters such as the 2010 earthquake, political instability and violence. These issues have led to families being unable to care for their children, leaving them orphaned or abandoned. Additionally, limited access to education and healthcare in some areas exacerbates the situation.
What does sustainable population mean?
A sustainable population is one that can be maintained at that number of people indefinitely without adversely impacting the environment or the quality of life of the members of that population.
What were the main Ojibway gods?
We are a Monotheistic Society having only one God, although we put more importance to his Wife, Nicomis, and Grandson, Monaboozho.
Once the famous Missionary, Pierre Marquette asked an Anishinaabe Mishkikiiwinini, Grand Medicine Holy Man, why our people worshipped the wrong God? The Ojibwé answered by asking Marquette why, after saying there is only one God, now says there are two? The right one and the wrong one.
