Answer:
see if the strips repel each other when brought close together
Explanation:
Electric fields can exert forces on objects, even if the objects involved are not touching. One way to demonstrate that electric fields exist around charged objects is to observe the effects of their forces at a distance.
Since Ike knows that each strip of tape carries a negative charge, he could see if the strips repel each other when brought close together.
The correct option is A ie the process whereby non-sister chromatids exchange genetic material
- Between prophase I and metaphase I, a process known as crossing over occurs in which two homologous non-sister chromatids join up and exchange various pieces of genetic material to create two recombinant chromosome sister chromatids.
- When genetic material is switched between two chromosomes, this process is known as crossing over.
- It is in charge of causing genetic variation among members of a species.
- Only the reproductive cells known as gametes undergo this process.
- The steps involved in crossing over are as follows:
1) Synapsis.
2) Chromosome duplication
3) Crossing over.
4) Terminalizataion.

Answer:
C) They are part of a community
Explanation:
A community represents the sum total of populations of different species present together in an area or ecosystem. In a community, the organisms of these different species may benefit or harm each other and exhibit little or more interdependence. In the given example, beer, insects, ants, chipmunks represent the organisms of different species that are present together in a habitat. They interact with each other in various ways. For instance, the bear is a predator of insects.
