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.

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.

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.

NADPH builds up in the STROMA of the chloroplasts during electron transport. In chloroplasts,  NADP+ is reduced by the ferredoxin-NADP+ reductase.

Nicotinamide adenine dinucleotide phosphate (NADPH) is the reduced electron form of NADP+.

The NADPH coenzyme is generated during the last step of the electron transport chain of the light-dependent reactions of photosynthesis.

NADPH is used by plant cells as an electron donor in different reactions associated with dehydrogenase and reductase enzymes.

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.
