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.
D. the relationship benefits both organisms. its mutual
The characteristics of all living things out of given options is
A) Respond to external stimuli
Well, for living things, it is important to respond to the stimuli because it helps them to reproduce and survive in the environment.
DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar<span> group, and a </span>nitrogen base<span>. The four types of nitrogen bases are </span>adenine<span> (A), </span>thymine (T), guanine (G) and cytosine<span> (C). The order of these bases is what determines DNA's instructions, or genetic code.</span>
Answer:
It will swell
Explanation:
Since it is only permeable to water, the cell will try and reach homeostasis with it surroundings (it will take in water to decrease the concentration of salt in the cell).
