Answer:
The main difference between prophase I and II is that during prophase 1, the pairing of homologous chromosomes or the synapsis allows the non sister chromatids to cross over at chiasmata, leading to genetic recombination between chromosomes. During prophase II,synapsis does not occur; hence, no genetic recombination takes place between the chromosomes
During Prophase I the Centrosome is duplicated during the interphase, which is a process prior to prophase while in Prophase II, the Centrosome is duplicated during the prophase II due to the lack of an interphase.
The carbon cycle is the process in which carbon moves throughout an environment.
Answer:
scientific method
Explanation:
The primary aim of research and scientific experiments conducted by scientists is to solve problems and provide factual answers to them. In order to accomplish this, a procedure called scientific method is employed.
Scientific method refers to a step-by-step procedure used to test the validity of an hypothesis. Scientific method uses the following steps;
1) Make observation
2) Ask a question
3) form an hypotheses.
4) perform an experiment
5) Analyze the results
Hence, SCIENTIFIC METHOD describes a series of steps designed to answer questions.
