Answer:

The cell organellles are visible in the electron microscope, but it is not possible to study the living cells in electron microscope. For study of genetic materials i.e., DNAs and RNAs is poosible through the help of electron microscope.  (ANSWER)

Explanation:

Answer:

when the nucleus is removed from the cell the cell can no longer function. the nucleus contains the blueprint (DNA) for all the cells operations and without it the organelles cant do their jobs.

c. the ventricles are relaxed and fill with blood is correct

Explanation:

Answer:

Technically, yes.

Explanation:

Depends on your point of view.    

NOTE: This excludes light, and photonic interaction. That technically doesn't make up anything, because it has no mass.  

Matter is anything that has mass and takes up space. Due to E=MC*2, energy and mass are relative, even though a small amount of mass, has a large amount of energy. So let’s backtrack. Matter is anything. Matter is energy. Matter is nothing? What about in an atom. Or in the vacuum of space? In an atom, between the nucleus, and the electron cloud, there is empty space. In the vacuum of space, most people think there is nothing. Just emptiness, until the next star, or the next planet. That is 100% wrong. I guess they are either thinking too hard or not enough. The vacuum of space actually has energy. Just a small amount of it. It takes up space, that check’s off. It has mass (excluding photons), that check’s off. And yes, it has energy. SO, since energy and matter are interchangeable, everything is made of energy, even though not everything is made of matter. Certain types of energy, sound, heat, light, are not made of energy. Does that mean that photons are not made of Matter? Well, sort of. They have no mass, so technically not, but they do have space and exert a force, which is also mysterious. So, I hope this confused you a little bit, with matter being energy, but not energy being matter. Here is something to spark the imagination: Is fire a solid, a liquid, or a gas

The role that is played by macromolecules such as starch and simple sugars in fruit storage and ripening is that the unripe bananas store starch in their chlorophyll.

Macromolecules refer to very large molecules. The four main classes of macromolecules include lipids, proteins, nucleic acid, and carbohydrates.

It should be noted that starch is stored in the chlorophyll content of the peel of the unripe bananas. During ripening, there'll be an increase in the breakdown of the starch that can be found in the fruit and this will ensure there's an increase in the glucose too.

To be precise, homeostasis is a process/phenomenon not a system. Homeostasis is actually the process of maintaining a stable internal environment despite changes in the external environment. There are mechanisms in organisms that regulate pH and this regulation is an example of homeostasis.

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.

Explanation:

Insulin is a hormone that helps control your body's blood sugar level and metabolism -- the process that turns the food you eat into energy. Your pancreas makes insulin and releases it into your bloodstream. Insulin helps your body use sugar for the energy it needs, and then store the rest.

Glucagon interacts with the liver to increase blood sugar, while insulin reduces blood sugar by helping the cells use glucose.
