Answer:
The third option is the correct answer.
Explanation:
As you may already know, a cladogram is a diagram capable of representing the evolution of living beings, through their ancestry and genetic similarities.
In a cladogram, the main line is the root and represents the common ancestor among all living beings that will be added throughout the cladogram. The adjacent lines, the main line are the branches and represent the groups of living beings represented. Each point between the lines, are the nodes and represent cladogenetic events.
As you can see in the cladogram shown in the question above, species C and D come from the same branch, which means that these species are more genetically close and that they have many similarities in their genomes. However, species B and C or D and E, despite having the same ancestor in common, come from different branches, which means that they are less genetically similar.
There are two types of polymers which are natural and synthetic polymers. Natural polymers do not affect the environment but synthetic polymers do. This type of polymers are produced by humans. These release reactants which are considered hazardous to humans and the environment. Synthetic polymers include rubbers, plastics, and adhesives, and these are considered non-biodegradable and non environmental friendly. As these build up in the environment, in causes problems such as chemical poisoning to all the living things around it.
The validity of the hypothesis cannot be confirmed or refuted from only one experiment. By using a series of experiments, the human error or measurement error is reduced to a minimum. Furthermore, more than one factor can be used to determine the validity of the hypothesis.
I will respond to this student that the experiment needs to be repeated multiple times before a conclusion can be drawn! Also, the data will refute or confirm the validity of the hypothesis and not the researcher's own opinion/rational.

Answer:
The box will not move because balanced forces are acting on it.
Explanation:
According to Newton's first law of motion, an object will remain in its state of rest or motion along a straight line unless acted upon by an unbalanced force.
An unbalanced force is an individual force acting on any side of an object which is not balanced by a force of equal magnitude acting in the opposite direction.
From the image, two forces of equal magnitude of 10 N are pulling the 100 kg box in opposite directions. Since the two forces, 10 N each are pulling the object in opposite directions, they are balanced forces. Therefore, the box will not move because balanced forces are acting on it.
