<u>Answer</u>: Option B experiments
<u>Explanation</u>:
- Causality is also known as causation or <em>cause and effect.</em> It is defined as the relationship that exists between cause and effect.
- Among types of research the experiments produce an outcome and have a cause and effect and thus can establish causality.

- Similarly, random and representative surveys are slightly biased in nature and not correct.
<em>Since the experiments have a cause and effect, they can establish causality.</em>
Answer:
body breaks down both the same way balance is key
leptotene : homologus pairing is formed and chromosomes start to get closer to each other.
zygotene: synapsis is formed between homologus chromosomes which is apoint oattachment.
pachytene:crosing over occer that homologus chromosomes exchange THIER GENETIC METERIALS.
DIPLOTENE: chiasmata formation disapear which was formed in pachytene.
diakinasis:homologus chromosomes start to seperate from each other.
