During the Flowing Water Model demonstration, observe the stream table while water is flowing through it. What do you notice? Record your observations on the lines below. You can use to Word Bank to help you describe what you see.
Answer:The speed of the water flowing downhill will be affected by the degree of incline, and any structures or topographical features in its path. The faster the water flows, the more erosion occurs. Water flowing downhill moves and deposits sand at the bottom of the river. The faster the water flows, the more sand will be deposited at the bottom. A delta at the mouth of a river forms in the same way. Although the formation of the “rivers” in this activity appeared very quickly, in reality rivers can take millions to billions of years to form a path from land to sea.

At a large desk or on the floor, choose a position to represent the Sun, and place Mercury a few inches from it. Predict the relative distances between each of the other planets, and space them out accordingly. Do you think the average distances between each of the planets stays relatively consistent or varies greatly? What leads you to this conclusion?
Assuming we are to perform this model to scale, with accurate and reliable data, we can conclude that the average distance between each of the planets would increase as we go.
Most science projects which involve creating a model of the solar system place each planet in perfect orbits at equal distances from one another. Accurate scientific data tells us that this is not the case.
The position of the planets in our solar system follow two trends:
Not all planets have perfectly circular orbits, and therefore are not always at the same distance The spacing between planets grows as we get further from the sun.The distance from the sun weakens the effects of the Sun's gravity on the planets, causing them to be further apart as well as causing increasingly erratic orbits. This leads us to the conclusion that the average distance between planets varies greatly.

spindle fibers attach to kinetochores during _____.
Answer:
Metaphase.
In prometaphase, kinetochores appear at the centromeres and mitotic spindle microtubules attach to kinetochores. In metaphase, chromosomes are lined up and each sister chromatid is attached to a spindle fiber. In anaphase, sister chromatids (now called chromosomes) are pulled toward opposite poles.
How does refrigeration of food prevent it from spoilage?
Refrigeration preserves food by slowing down the growth and reproduction of microorganisms as well as the action of enzymes which cause food to rot. Freezing food slows down decomposition by turning residual moisture into ice, inhibiting the growth of most bacterial species.

How does peer review of scientific articles and replication of test results contribute to the development of scientific theories?
Answer:Careful evaluation of research results by other scientists ensures that only solid and legitimate research results are published, and helps prevent faulty research or false claims from being viewed as scientific fact.
Explanation: it guards against fault science contaminating the literature on which all scientists rely. a hypothesis must be tested repeatedly and those tests must produce the same results before the scientific community will accept the hypothesis.
Peer review of scientific articles and replication of test results are essential processes that contribute significantly to the development and refinement of scientific theories. They help ensure the accuracy, credibility, and robustness of scientific knowledge. Here's how they contribute to theory development:
1. **Quality Assurance:** Peer review involves subjecting a research paper to critical evaluation by experts in the field before publication. This process helps ensure that the research is of high quality, methodologically sound, and contributes meaningfully to existing knowledge.
2. **Identification of Errors and Flaws:** Peer reviewers scrutinize the methodology, data analysis, and interpretations presented in the paper. If there are errors, inconsistencies, or weaknesses, reviewers can identify and point them out. This process helps prevent flawed or misleading research from being published.
3. **Enhancement of Clarity:** Reviewers provide feedback on the clarity of the paper's writing, organization, and presentation of results. This feedback helps authors improve their communication, making the research more accessible to the broader scientific community.
4. **Strengthening Hypotheses and Arguments:** Reviewers assess the logic and coherence of the research's hypotheses, arguments, and conclusions. Constructive feedback from peers can lead to refining hypotheses, modifying experimental designs, or reevaluating conclusions based on the evidence.
5. **Contribution to Scientific Discourse:** Peer-reviewed articles become part of the scientific literature, where they contribute to ongoing discussions, inspire new research directions, and serve as building blocks for future studies and theories.
**Replication of Test Results:**
1. **Verification of Findings:** Replication involves conducting the same or similar experiments to confirm the validity of previously reported results. If multiple independent researchers can replicate the same results, it enhances the credibility of the findings and supports the robustness of the theory.
2. **Identifying Errors and Biases:** Replication attempts may uncover errors, biases, or confounding factors that were not initially identified. This process helps filter out inaccurate or biased results, ensuring that only reliable findings contribute to the body of knowledge.
3. **Assessment of Generalizability:** Replication studies conducted in different settings or with different populations help assess the generalizability of findings. A theory that holds up across diverse conditions gains stronger support.
4. **Refinement of Hypotheses:** In cases where replication produces inconsistent results, researchers may need to revisit their hypotheses, experimental design, or methodologies. This process encourages critical thinking and refinement of theories to better explain observed phenomena.
5. **Building a Cumulative Body of Knowledge:** Replicated results provide a foundation upon which subsequent researchers can build. As more replications occur, a body of consistent and reliable evidence accumulates, contributing to the establishment of well-supported scientific theories.
In summary, peer review and replication play vital roles in the development of scientific theories. Peer review ensures the quality and accuracy of research before it enters the scientific literature, while replication confirms and strengthens the validity of findings. Both processes foster a dynamic and self-correcting scientific community that continuously refines and advances our understanding of the natural world.

Water is a polar molecule because
Answer:
Water is a polar molecule because of its unequal sharing of electrons.
Answer:
The reason why Water is considered a polar molecule is because of Unequal sharing of electrons.
Explanation:
This makes the oxygen end of the molecule slightly negative. Since the electrons are not near the hydrogen end as much, that end is slightly positive. When a covalent bonded molecule has more electrons in one area than another, it is called a polar molecule.
if blood calcium levels drop below 8.5 mg/dl which hormone is likely to be activated?
Answer:
Parathyroid Hormone (PTH)
Explanation:
The major function of the parathyroid glands is to maintain the body’s calcium level in both the blood and bones.
There is a narrow range of calcium required for the nervous and muscular systems to function properly. (A normal calcium level in the blood stream ranges from 8.5-10.2 mg/dL ).
When blood calcium levels drop below a certain level, receptors in the parathyroid gland release parathyroid hormone (PTH) in proportion to the amount of calcium that is required by the body. This hormone increases blood calcium levels by stimulating osteoclasts to release calcium by breaking down bone. Osteoclasts are cells in the bones that break down and remodel bone tissue.

Describe the behavior of the chromosomes in then second division of meiosis.
Answer:
The typical behavior of chromosomes in meiosis is that homologous pairs synapse, recombine, and then separate at anaphase I. At anaphase II, sister chromatids separate. However, studies of small chromosomes in maize derived from a variety of sources typically have failure of sister chromatid cohesion at anaphase I. This failure occurs whether there is pairing of two copies of a minichromosome or not. These characteristics have implications for managing the transmission of the first generation artificial chromosomes in plants. Procedures to address these issues of minichromosomes are discussed.
Normal chromosomes enter into meiosis following DNA replication. The homologous pairs find each other in the process of synapsis. Recombination exchanges parts of the homologs involving two of the four chromatids present. Then in anaphase I, each member of the pair segregates to opposite poles and into the two cells resulting from meiosis I. In contrast to mitosis, the sister chromatids of each homolog remain attached to each other. At meiosis II the sisters now separate to opposite poles. The consequence of this sequence of events is that segregation of genetic markers on the two members of the pairs of homologs enter into different gametes that will eventually be formed after meiosis. However, small chromosomes as observed in maize do not follow these rules. In this review, we describe the information known about these minichromosomes and what they inform us about meiotic processes. Also, the behavior of small chromosomes impacts how engineered minichromosomes will behave and so information about them is important for practical applications as well.
