Answer:
Parasitism.
Explanation:
Parasitism, in biology, is defined as a relationship between different species, formed by a parasite and a host. So, basically the parasite lives in or on the host, causing it harm. Parasites can be describe as predators that eat less than one prey unit, that is, they feed them selves slowly, they don't kill the prey instantly as actual predators do.
So, in this case, we are talking about leeches, which are defined as parasitic worms which lives in freshwater environments. They feed themselves by sucking blood from the host.
Therefore, the relation between these two species is Parasitism.

See the graph in attachment
Explanation:
In this problem we have to draw a velocity-time graph for an object travelling initially at -3 m/s, then slowing down and turning around.
In the graph, we see that the initial velocity at time t = 0 is
and it is negative, so below the x-axis.
Later, the object slows down: this means that the magnitude of its velocity increases, therefore (since the velocity is negative) the curve must go upward, approaching and reaching the x-axis (which corresponds to zero velocity).
After that, the object's velocity keep increasing, but now it is positive: this means that the object is travelling in a direction opposite to the initial direction, so it has turned around.

Parallelism is a property shown by the rails of a railway track.
Option B
Explanation:
Parallelism is the property of the lines which do not meet in a plane, those lines which "do not intersect or touch each other" are parallel to each other.
In the given example, railway lines of railway track are said to be parallel since they are at an equal distance to each point so that the wheels of the train be on track. Since these railway lines do not meet each other even at infinity, they are said to be parallel.
Answer:
parallelism
Explanation:
i took the quiz on Edge 2020 and got it right i promise :)
also this question is mostly based on common sense because if two lines will never intersect they are parallel and train tracks will never intersect so they are also parallel and they only word there that has parallel in it is parallelism so the answer has to be parallelism.

Well, we know that the total energy in a closed system remains constant.
The problem with the story of Eva is that she is not in a closed system.
If the dark room were really a closed system, then she could press the
button or turn the switch all day, and the lamp could not light. It needs
electrical energy coming in from somewhere in order to turn on.
Let's say that Eva used her arm muscles to strike a match and light the
candle on the table. Then we would have have food energy, muscle
energy, chemical energy in the match, chemical energy in the candle,
heat and light energy coming out of the candle, heat energy soaking into
her hand, light energy bouncing off of the book and into her eyes ... all
going on during the story, and the sum total of all of them would remain
constant.

Power, as you should have learned in your class, is a rate; it needs to be multiplied by time to get the amount of energy
Thus, your answer...time.
To calculate power, divide the amount of energy transferred by time.
Final answer:
Power in physics is the rate of energy transferred per unit time. It can be calculated by dividing the amount of energy transferred by the time required for the transfer.
Explanation:
In Physics, power is defined as the rate of transferring energy or the amount of energy per unit time. If you want to calculate the power, you take the amount of energy transferred and divide it by the time it takes for that transfer to occur. For example, if a light bulb transfers 100 joules of energy over 10 seconds, the power would be 100 joules divided by 10 seconds, which equals to 10 watts.

Answer:
because a complete equation must have all the elements present on the left hand side of the arrow on the right hand side of the arrow as well, and to be balanced there must be the same number of each type of atom, so both A and C are full equations, but A is not balanced because although there are two oxygen atoms on each side of the arrow, there is only one hydrogen atom on the left and two on the right, thus the right hand side is 'heavier' than the left and the equation is unbalanced.
