Answer:
C. under 1 and 2. because Earth's entire outer layer is made of hard, solid rock
Explanation:
Just because 2 is under water does not mean it will not work it will just be very difficult. But at the bottom of the sea there is always solid rock.
Answer:
The graph illustrating such a phenomenon will show a sharp curve in upward manners in the beginning but then will grow downwards as the predation increases.
Explanation:
When a rabbit population is introduced in a habitat, the new habitat will have abundant food for the rabbits. As a result, the population of the rabbits will grow at a much faster rate and hence the graph will move sharply upwards in the beginning. But with the passage of time, the predators of the rabbits will also increase due to the abundance of their preys. More predators will feed on more rabbits and hence a slow decline in the curve will be seen afterwards.
You will your on this certain day hope this helped
Answer:
Decrease
Explanation:
Acceleration is inversely proportional to the mass of an object.
Acceleration decrease as the mass of the object increase
If u use the formula F=ma to calculate, you will get
a=0.5m/s2 for the first situation (m=10kg) and a=0.25m/s2 for the second situation (m=20kg)
These alveoli are the smallest types of lung tissue, and one of the most important. In addition to being the primary means by which oxygen enters and carbon dioxide escapes the bloodstream, these small pouches of air are also the reason why the lungs do not totally collapse when a person breathes out. This is because they contain a cell that secretes a special chemical to lower the surface temperature to prevent lung collapse. The alveoli also contain other cells that secrete chemicals to attack and remove any foreign objects in the lungs, such as dust, dirt and other debris.
In addition to making up alveolar sacs, alveoli also form alveolar ducts. It is estimated that there are more than 300 million alveoli in the human lungs, all of which are located in either alveolar ducts or sacs that are found at the end of the smaller passageways, or bronchioles, in the lungs.
SHORT ANSWER:
Alveolar sacs contain tiny pouches called alveoli, whose primary function is gas diffusion. These clusters of alveoli have thin walls that allow oxygen to pass easily from the lungs into the bloodstream and carbon dioxide to flow from the blood to the lungs so it can exit the body.
