Why do dogs not catch your cold?
The common cold in humans is caused by rhinovirus, which is pretty specific to humans. There are other strains of rhinovirus that infect dogs, but those strains don't infect humans. The barrier for this is the type of protein on the surface of the cells of the upper respiratory tract - there are different proteins on human cells than there are on canine cells. The virus is very well adapted to only one species, so a human-adapted rhinovirus can only infect humans while a canine-adapted rhinovirus can only infect dogs.
What is one way that early humans adapted to cold environments?
Scientists believe that they moved in groups from place to place, creating shelters with tools and using fire to keep warm. Building shelters allowed them to live in colder climates and in places where there were no cave to provide natural shelter. Being able to control fire helped them survive the cold, harsh climates of where they traveled to.
What is one way humans have modified or adapted to the environment?
The weather and illnesses
What is the most highly adapted animal?
There are many highly adapted animals. One of them is the penguin. The penguin's color helps it to protect against the heat and cold. When it is cold the penguin uses its black skin to absorb heat. When it is hot the penguin uses the white skin to reflect light.
How did the environment affect the Neanderthals?
Their bodies were adapted for cold weather. Changing climate is considered one of the reasons for why they died out.
Identify one cost and one benefit of farming for early humans?
Cost: Early humans had to spend a lot of time and effort hunting and gathering food to sustain themselves, which could be physically taxing and dangerous. Benefit: Farming allowed early humans to settle in one place, leading to the development of permanent communities, more stable food sources, and eventually the rise of civilizations.
One difference between early modern humans and neanderthals is that early modern humans?
the early modern humans lived a farming lifestyle while the neanderthals still were nomadic people
What was one reason why groups of early humans rarely stayed in one place for very long?
Some early humans were nomadic because they did not know anything about agriculture and they had to follow the food (buffalo, deer, etc...) where ever it moved to.
Goats were one of the first animals to be domesticated by humans. How were early humans' lives impacted by the domestication of goats?
they had a new source of food
How are humans adapted to the environment?
we humans are adapted to our environment by changing what we do as a routine, or even how ourselves adapt. For example, when it turns from summer to winter, we would wear different clothes to adapt to the cold weather. We wouldn't wear short sleeve shirts when it's cold.
Which continent was the only one NOT inhabited by early humans 1.) Africa2.) Asia3.) Antarctica4.) Australia?
Antarctica. Humans did not arrive there until 1899.
What viruses can affect humans but not animals?
One is T.B. and another is the cold, but I don't much about anything else but that.
