Answer:
Calcium is a silvery-white, soft metal that tarnishes rapidly in air and reacts with water. Calcium metal is used as a reducing agent in preparing other metals such as thorium and uranium. It is also used as an alloying agent for aluminium, beryllium, copper, lead and magnesium alloys. Calcium is essential to all living things, particularly for the growth of healthy teeth and bones. Calcium phosphate is the main component of bone. The average human contains about 1 kilogram of calcium.
Explanation:
The answer I would say is A.
The sun doesn’t make water
And electricity doesn’t come from the water cycle.
Answer:
Answer 1: The purpose of an experiment is to test a hypothesis.
Answer 2: Scientists commonly measure intensive properties to determine a substance's identity, whereas extensive properties convey information about the amount of the substance in a sample.
Answer 3: These principles are at work in the fundamental elements of the scientific method, such as formulating a hypothesis, designing an experiment to test the hypothesis, and collecting and interpreting data. In addition, more particular principles characteristic of specific scientific disciplines influence the methods of observation; the acquisition, storage, management, and sharing of data; the communication of scientific knowledge and information; and the training of younger scientists.
Answer 4: Data collection tools refer to the devices/instruments used to collect data, such as a paper questionnaire or computer-assisted interviewing system. Case Studies, Checklists, Interviews, Observation sometimes, and Surveys or Questionnaires are all tools used to collect data.
Answer 5: The purpose of an experiment is to test out your hypothesis. If your hypothesis is correct, then it is a theory that could work every single time the experiment has been performed by scientists.
Answer 6: ?
Answer 7: the first step toward teaching my students how to critically think about how they structured an argument or explanation was to implement the Claim, Evidence, Reasoning (CER) framework. While the premise behind CER isn’t anything new to the way science teachers already think, it provides an entirely different approach toward how students connect their experiences and previously learned content into something that is much more reflective of being scientifically literate.
Answer 8: ?

Answer:
1-Meiosis:
- Independent assortment: Anaphase I
- Segregation: Anaphase II
2-Mitosis
- Segregation: Anaphase
Explanation:
The Principle of Independent Assortment described by Mendel indicates the mechanism by which different genes get sorted into gametes (i.e., eggs and sperms in mammals) independently of one another, while the Principle of Segregation indicates the mechanism by which gene variants (i.e., alleles) segregate (separate) into gamete cells. In eukaryotic organisms, independent assortment occurs during anaphase I of meiosis, when each pair of homologous chromosomes separate. The assortment of homologous chromosomes during anaphase I explain how genes on different chromosome pairs will segregate independently of one another. On the other hand, the separation (segregation) of sister chromatids occurs in Anaphase II, where gametes carrying single gene variants (i.e., alleles) for each locus are generated.
