How are combustion,
respiration, and decomposition similar to each
other?
Answer:
The waste products of carbon dioxide and water are also formed. Combustion, which is the burning of carbon compounds, which are fossil fuels, is often compared to cellular respiration because the two processes are extremely similar. ... It's as if our bodies burn our food for energy.
Combustion, respiration and decomposition are similar to each other because they release carbon dioxide.
Combustion is the reaction that occurs between an oxidizable material and oxygen, which is revealed through flames and generates the release of energy.
The different components that are completely oxidized, gives rise to the formation of liquid water and carbon dioxide and even sulfur dioxide.
Respiration is a gas exchange system with the environment, where a fuel molecule, glucose, is oxidized.
Humans take in oxygen through inspiration and exhale carbon dioxide as a waste product produced by the body.
The decomposition of organic matter is useful for microorganisms for two reasons: as an energy supply for their growth, and as a carbon source for the formation of new cellular material.
Carbon dioxide, methane, organic acids, and alcohols are waste products released in the acquisition of energy.
Therefore, we can conclude that combustion, respiration and decomposition are similar to each other because they release carbon dioxide.

Monomers are the building blocks of larger molecules called polymers. A polymer consists of repeating monomers bonded to each other with covalent bonds.
Use the draw pad to connect each monomer to its polymer.
Answer:
Explanation: It connects to each one shown below. All correct.
The monomer of DNA is a nucleotide. The monomer of glucose is carbon, hydrogen, and oxygen.
What are monomers and polymers?The simplest form of polymers is monomers. To create polymers, each monomer is combined. Usually, a double bond or triple bond holds the monomer together.
Typically, monomers contain two free electrons that pair together and create a double bond among themselves. The monomers of cellulose are an example of a monomer and contain glucose.
A monomer is a molecule that, when combined with additional monomers of the same kind, can create a polymer, such as glucose (C6H12O6). A biological polymer made of several -glucose units is cellulose, which serves as an illustration of this.
Therefore, the monomer of DNA is a nucleotide. The monomer of glucose is carbon, hydrogen, and oxygen. The monomer of their polymers is matched in the added picture.

Plants release oxygen into the
atmosphere by...
A. Splitting apart water molecules
B. Splitting apart carbon dioxide
C. Attaching water together
D. Attaching oxygen together
Answer:
A
Explanation:
Plants use water in the process of photosynthesis, (to make food) but they don't need all of it. They use carbon dioxide, the stuff people and animals breath out, and release oxygen for us to breath, then we breath out carbon dioxide again and the process happens again.
Fun fact: Did you know that rain forests make their own weather? Plants not only release oxygen into the air, but tiny droplets of water. (water vapor, and this part of the water cycle is called transpiration) Those droplets condense and form clouds. That's why it rains every day in tropical forests. Cool huh?

A student wins a trophy. It is a metal cup on a black plastic base. The student cleans the trophy. She holds one of the metal handles and rubs the rest of the trophy with a dry cloth. Why the plastic base does becomes negatively charged? B) The metal cup does not become charged when she rubs the trophy. Suggest why the cup does not become charged.
Answer:
In this given statement , the plastic base becomes negatively charged because plastic is an insulator . And the metal cup does not become charged because metal is a conductor.
Explanation:
Reason behind , why plastic base becomes negatively charged -: When a plastic base is rubbed with a dry cloth in the metal trophy, electrons are shifted from one material to the other. Thus, the substance that gains electrons (which is the plastic base) becomes negatively charged. thus , the plastic is an insulator , which causes charge (negative ) by rubbing.
Reason behind , why the metal cup does not become charged -: The metal cup is a conductor, and the surplus charge on the metal flows to the person who charges the cup and to the ground so that it is not charged. Thus, rubbing a metal can trigger hand\finger injury because metals generate excess heat in rubbing .

Describe two types of evidence–other than the comparison of DNA sequences–that can be used to determine the phylogeny of organisms. Discuss one strength of each type of evidence you described.
Answer: Comparing the DNA sequence of the organisms can also tell you how closely related species they are. It can give you even more information since the original DNA is how the amino acid sequence of cytochromes is coded for.
Looking at embryonic development also helps you determine the phylogeny of organisms because a way an embryo develops can be very similar to the way another species develops but then both are full-grown they look very different and its tuff to explain how close they might be related

can you please write a paragraph on how to write a lab report
Explanation:
A typical lab report would include the following sections: title, abstract, introduction, method, results and discussion. Title page, abstract, references and appendices are started on separate pages (subsections from the main body of the report are not).
How do you start a lab report?
Sometimes an introduction may contain background information, briefly summarize how the experiment was performed, state the findings of the experiment, and list the conclusions of the investigation. Even if you don't write a whole introduction, you need to state the purpose of the experiment, or why you did it.
Answer:
Explanation:
The title says what you did. It should be brief (aim for ten words or less) and describe the main point of the experiment or investigation. An example of a title would be: "Effects of Ultraviolet Light on Borax Crystal Growth Rate". If you can, begin your title using a keyword rather than an article like "The" or "A".
Usually, the introduction is one paragraph that explains the objectives or purpose of the lab. In one sentence, state the hypothesis. Sometimes an introduction may contain background information, briefly summarize how the experiment was performed, state the findings of the experiment, and list the conclusions of the investigation. Even if you don't write a whole introduction, you need to state the purpose of the experiment, or why you did it. This would be where you state your hypothesis.
List everything needed to complete your experiment.
Describe the steps you completed during your investigation. This is your procedure. Be sufficiently detailed that anyone could read this section and duplicate your experiment. Write it as if you were giving direction for someone else to do the lab. It may be helpful to provide a figure to diagram your experimental setup.
Data
Numerical data obtained from your procedure usually presented as a table. Data encompasses what you recorded when you conducted the experiment. It's just the facts, not any interpretation of what they mean.
Results
Describe in words what the data means. Sometimes the Results section is combined with the Discussion.
Discussion or Analysis
The Data section contains numbers; the Analysis section contains any calculations you made based on those numbers. This is where you interpret the data and determine whether or not a hypothesis was accepted. This is also where you would discuss any mistakes you might have made while conducting the investigation. You may wish to describe ways the study might have been improved.
Conclusions
Most of the time the conclusion is a single paragraph that sums up what happened in the experiment, whether your hypothesis was accepted or rejected, and what this means.
Figures and Graphs
Graphs and figures must both be labeled with a descriptive title. Label the axes on a graph, being sure to include units of measurement. The independent variable is on the X-axis, the dependent variable (the one you are measuring) is on the Y-axis. Be sure to refer to figures and graphs in the text of your report: the first figure is Figure 1, the second figure is Figure 2, etc.
Edit: A typical lab report would include the following sections: title, abstract, introduction, method, results and discussion. Title page, abstract, references and appendices are started on separate pages (subsections from the main body of the report are not). How do you start a lab report? Sometimes an introduction may contain background information, briefly summarize how the experiment was performed, state the findings of the experiment, and list the conclusions of the investigation. Even if you don't write a whole introduction, you need to state the purpose of the experiment, or why you did it.
