When you shiver, that's actually how you help yourself stay warm! It's your immediate instinct reaction to do so when you're cold, so there will be more heat produced, and they occur by your muscles moving. =)
Im not 100% sure but the best answer I can give is Prokaryotes because they came to be around the time oxygen did as well.
Well, depending on how long the migration is, many of the animals (mainly birds) could get sick and die, lowering the population. They could be shot by hunters, lowering the population. The children of the population could get left behind and lose their way, lowering the population. I'm not entirely sure how the population could grow other than them finding and staying with another group of their own kind. hope I was helpful! :)
Answer:
Protons, neutrons, and electrons: Both protons and neutrons have a mass of 1 amu and are found in the nucleus. However, protons have a charge of +1, and neutrons are uncharged. Electrons have a mass of approximately 0 amu, orbit the nucleus, and have a charge of -1.
Explanation:
Random distribution is the probable distribution pattern of opossums.
Explanation:
The opossums are the member of low density population. They are sparsely distributed because of the low number. There are troubles for them to find a mate.
Their habitat makes them solitary as they have flexible dietary habits. they are terrestrial animals living in burrows and are nocturnal.
They have random distribution pattern. The opossums are distributed in the population as random. The mates in opossums do not have choices of mates and the environment conditions in which they live are stagnant.(having no social life). Random interaction is seen in <em>species which do not have any social bonding</em> between the species of the animals or plants.
