The nine activities that scientists engage in as a part of scientific inquiry are the following:
1. Observe
2. Define the problem
3. Form a study question
4. Research the problem
5. State the expectations (hypothesis)
6. Experiment and gather data
7. Analyze the results
8. Reflect on the findings
9. Communicate with the wider community
Answer:
The correct answer will be options 2 and 4.
Explanation:
Classification is a taxonomical system of identification, nomenclature and arrangement of the unidentified organism in taxonomical categories based on the similarity of the characters.
This method is used in the identification of new species by comparing the characters with other identified species based on the similarities which are then arranged into taxonomical categories and nomenclature method is performed thereafter to name the unidentified organism.
Thus, options 2 and 4 which include identification and nomenclature are the correct options.
Answer:
DNA content is halved in both meioses I and meiosis II. Ploidy level changes from diploid to haploid only in meiosis II.
Explanation:
In meiosis, one diploid cell produces four haploid cells. At the end of meiosis I, just like in mitosis, we will have two diploid daughter cells and then these two cells undergo cellular division again. In this secondary division, more precisely in the anaphase II, the centromere divides <u>(this process does not happen in the meiosis I anaphase I, where homologous chromosomes move together to opposite poles)</u> and sister chromatids move to opposite poles, leaving four individual cromatids following a cytoplasmatic division forming four new haploid cells.
Answer:
Salt is a compound
Explanation:
A compound had fixed mass ratio of elements.
And the characteristics of the compound is different from its constituents. E.g taste of soap is different from its constituents like palm oil, soda, fragrance etc
Other compounds are water, caustic soda, limestone etc
