Answer:
One factor limits a population at a time. Suppose the area that had only enough food for 500 armadillos suddenly had enough food for 2,000 armadillos, but only enough water for 1,000 armadillos. The population still couldn't grow to 2,000 armadillos. Water would keep the population at 1,000 armadillos. In this case, water is the limiting factor.
Explanation:
The size of a population is limited by the carrying capacity of the environment. The carrying capacity is the maximum number of individuals that an environment can support. The carrying capacity of an environment can be limited by the availability of food, water, shelter, and other resources. Biodiversity is the variety of life in an area. The carrying capacity of an environment can also be limited by the number of different species that can coexist in an area.
Chargaff's rules state that DNA from any cell of any organisms should have a 1:1 ratio (base Pair Rule) of pyrimidine and purine bases and, more specifically, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine. This pattern is found in both strands of the DNA.
Answer:
2. The system will be defined by all the parts that act directly on the object, and the object itself.
So the parts are:
The ball.
The air.
The ground. (because this limits the motion of the ball)
The gravitational force (the force that pulls down the ball)
Why is it not the hand or you a part of the system? Because the phenomena is "a ball being dropped" the only action that you do in the ball is release it (you do not impulse it or anything) and we have our time t = 0s, when the ball is dropped, so the hand that was holding the ball is not in the picture for t ≥ 0s, then it is not part of the system.
3. Using what i wrote above, your hand is not in the system.
4. The air is important because it put resistance to the motion of the ball, if there was void, the ball would reach the ground in less time.
5. It is really hard to draw in a computer, so i will give a rough sketch of the system in this case:
Where: g = gravitational force.
H = initial height of the ball, which is really important for this problem.
