Answer: The charges of the objects are A: Positive and B: Negative.
Explanation-
The electric field lines are pictorial representation of the electric field in terms of imaginary lines.
The direction of electric field is away from the positive charge and is directed towards the negative charge.
In this question, the electric field lines are emerging from A and coming towards B.
Thus, the right answer is A: Positive and B: Negative.

ANOVA is used to test the association of categorical variable with the numeric variable, so it won’t be an appropriate use in the above condition.
Explanation:
ANOVA test include the testing of groups and their difference to accept or reject the hypothesis of a survey. It is applied on group of people having same condition and trying different therapies to see which is better. It can also be used to apply on two tests performed by one group.
But here in the above-mentioned condition, one test is being observed by people having different conditions. So, the ANOVA test wouldn’t be appropriate here.
Answer:
Down syndrome is a genetic disorder caused when abnormal cell division results in an extra full or partial copy of chromosome 21. This extra genetic material causes the developmental changes and physical features of Down syndrome.
Explanation:
Answer:
<em>It shows the number of individuals living at each age interval plotted versus time.</em>
<em>It helps to compare life histories of different populations. </em>
<em> You can compare the life histories of birds, frogs, and humans at the same time.</em>
Explanation:
A survivorship curve can be described as a graph which illustrates how many individuals survive to a certain age in a given population. A survivorship curve can also be used to study life histories of different organisms. For example, you can illustrate the life history of birds, frog and humans in a population compared to each other in a survivorship curve.
