Answer:
Pros of Biofuels
Renewable – Biofuels are produced from plants and other organic material, so it can be replenished constantly. This is in contrast to the fossil fuels, which are constantly in the process of being depleted.
Clean – Biofuels are environment-friendly. They are much efficient & cleaner than fossil fuels, producing less air pollution and using materials that would otherwise be considered as waste products. Biofuels cause much less greenhouse gas emissions in comparison to the conventional types of transport fuels.
Inexpensive – They can be made easily by using local materials. Biofuels are very cheap to afford. They are the cheapest types of fuels available in the world.
Flexible – can be easily mixed with other fuels.
Additives – Biofuels like ethanol and biodiesel are better for car engines than fossil fuels. Even if not being used as the main fuel source, they can be used as additives to improve performance.
Carbon neutral – the amount of carbon dioxide created by the burning of biofuels is equal to the CO2 absorption capacity of the plants. Hence, no extra CO2 remains in the atmosphere.

what is fart? explain and what do you call it?
Answer:
Farts — also called flatus (say: FLAY-tuss) or intestinal (say: in-TESS-tuh-null) gas — are made of, well, gas! When you eat, you don't swallow just your food. All of these gases in the digestive system have to escape somehow, so they come out as farts! Gases are also what can make farts smell bad.

Section I: Experimental Overview
Use your answers from questions 1–3 as the basis for the first section of your lab report. This section provides your reader with background information about why you conducted this experiment and how it was completed. Outline the steps of the procedure in full sentences. It also provides potential answers (your hypothesis/es) relative to what you expected the experiment to demonstrate. This section should be 1–3 paragraphs in length.
Section II: Data and Observations
Use your answers from questions 4–5 as the basis for the second section of your lab report. This section provides your reader with the data from the experiment, in a summarized and concise way. No paragraphs are required for this section, but you do need to include the key data and observations from which you will generate your analysis and discussion. This section is objective.
Section III: Analysis and Discussion
Use your answers from questions 6–8 as the basis for the third section of your lab report. This section provides your reader with your interpretation of the data set. You will also give an example of any calculations or formulas you used to analyze your data. Also, you will want to include any graphs that you made and interpret them for the reader.
If you did construct graphs, your Student Guide included information on which graphs to construct. Graphs should have the following:
a. Appropriate titles
b. Appropriate labels for each axis
c. Appropriate scales for each axis
d. Correct units for the data
Complete a rough sketch of each graph. Explain in one or two sentences what trend the reader should observe in each of your graphs.
Mention any problems, unusual or unexpected data, or other factors with the experiment here, and suggest possible causes. This section can be somewhat subjective, unlike Section II, because you are free to include your personal interpretations or even speculation if it adds constructive, reasonable insight to the discussion.
This section is variable in length, and should likely be the longest part of your report.
Section IV: Conclusions
Use your answers from questions 9-11 as the basis for the fourth section of your lab report. In this section you will summarize the outcome of the experiment, and discuss how the original hypothesis(es) was (were) either supported or refuted. Use logic and reason in explaining your statements, and be sure to refer to specific data from your experiment that supports your argument.
This section also demonstrates your understanding of the experiment, through your ability to offer constructive criticism about its design and make suggestions for future experimentation. There are always ways that experiments can be improved. Now that you are a veteran of this experiment and have experience with the procedure, offer some advice to the next scientist about what you suggest and why.
This section should be 1–2 paragraphs long.
Overall
When complete, the lab report should be read as a coherent whole. Make sure that you connect different pieces with relevant transitions. Review for proper grammar, spelling, punctuation, formatting, and other conventions of organization and good writing.

30 POINTS!! Type one to two paragraphs describing the full water cycle. Be sure to use full sentences and proper grammar.
Answer:
The water cycle is the way that all water chases after as it moves Earth in various states. Fluid water is found in seas, streams, lakes—and even underground. Strong ice is found in icy masses, day off, at the North and South Poles. Water fume—a gas—is found in Earth's air.
The water cycle, otherwise called the hydrologic cycle or the hydrological cycle, depicts the constant development of water on, above and underneath the outside of the Earth. There are four main stages in the water cycle. They are evaporation, condensation, precipitation and collection. Let's look at each of these stages. Evaporation: This is when warmth from the sun causes water from oceans, lakes, streams, ice and soils to rise into the air and turn into water vapour (gas).

Which question can be used to evaluate reliability of a source?
“Do these results support the author's own opinion?”
“Is this data challenged by anyone in the public?”
“Is this research relevant to me?”
“Who was paid to do this research?”
Answer:
Do these results support the Author's own opinion?
Explanation:
The question can be used to evaluate the reliability of a source is Do these results support the author's own opinion?
In sources (books, articles, etc), reliability implies the information of a source can be trusted. This occurs if:
All the information is based on factsThe information is not manipulated by the author's opinion or interestsIn this context, it is expected the information of the source is objective rather than influenced by the author's opinion. Therefore, one way to check the reliability of a source is "Do these results support the author's own opinion" because if the information is manipulated by a personal opinion, the source is not reliable.
Also, other questions are not appropriate because they are related to other aspects such as relevance, not reliability.

Specific proteins produced in a cell are directly related to the A. Number of mitochondria in the cell. B. Sequence of sugars and phosphates in the cell. C. Type of ribosomes in the cell. D. Sequence of nucleotides in the DNA of the cell.
Answer:
D. Sequence of nucleotides in the DNA of the cell.
Explanation:
Proteins are a type of biomolecules in living systems responsible for many phenotypic characteristics in organisms. Proteins are synthesized by a process called gene expression, which encompasses transcription and translation.
Using the central dogma of biology to trace, DNA (genes) contains information that encodes the production of proteins in the body. Therefore, the sequence of nucleotide bases in the DNA of a cell determines the sequence of mRNA that will be produced during transcription and ultimately, determines the specific type of proteins (amino acid chain) that will be produced in a cell during translation.

What if researchers followed a similar method used in this activity to calculate the correlation coefficients for the gene expression patterns of every patient with osteosarcoma and they found that all patients fell into two categories of gene expression patterns? What would this tell you about the single disease we call osteosarcoma? How might this information affect osteosarcoma cancer patient diagnosis and treatment in the future?
Answer:
- Abnormal gene expression patterns can lead to osteosarcoma
- Different signaling pathways (at least two) are involved in osteosarcoma
- Differentially expressed genes might be promising biomarkers for early detection of osteosarcoma
Explanation:
Cancer can be defined as a group of genetic diseases that are characterized by uncontrolled/inappropriate cell growth. In general, cancer pathways are associated with abnormal expression of signaling components that disrupt the regulatory networks capable of controlling cell function, thereby cancerous cells can inhibit programmed death cell (apoptosis). Osteosarcoma is one type of cancer disease that starts in the bones, i.e., this disease may be triggered by overactivity of bone cells. Additionally, it is important to note that different immune-related genes were recently found to be dysregulated in osteosarcoma. For example, differentially expressed immune-related genes involved in PI3K/AKT, MAPK and JAK-STAT signaling pathways have shown prognostic value in this disease.
Abnormal gene expression patterns can lead to osteosarcoma, different signalling pathways are involved in osteosarcoma, and differentially expressed genes might be promising biomarkers for the early detection of osteosarcoma.
What is the cause of osteosarcoma?Most osteosarcomas are not caused by inherited gene modifications, but instead are the effect of gene changes acquired during the individual lifetime.
Sometimes these gene modifications are caused by radiation therapy used to treat another form of cancer because radiation can harm the DNA inside cells.
Thus, these are the following reasons.

Why do different individuals of the same species have different traits?
OA. Individuals have differences in their genes that result in protein variations.
OB. Individuals have proteins that produce genes with completely different functions from other individuals.
OC. Individuals have different proteins that cause variations among their genes.
OD. Individuals have different genes that produce proteins with completely different functions from other individuals.
answer : a
explanation : a species shares ALMOST all of the DNA with each other with just small differences
Different individuals of the same species have different traits because individuals have differences in their genes that result in protein variation. Hence, option A is correct regarding variation.
Why do individuals of different species exhibit different characteristics?
The species is a group of individuals that can reproduce among themselves and can produce fertile offspring. Individuals of a species have genetic variation among them as they are formed by the process of meiosis.
In meiosis, genes cross over and recombination takes place, resulting in the formation of offspring that show some variation from their parents. These characters or traits are encoded in the gene. When these are expressed in the process of translation, the variation is seen.
This genetic variation doesn't make them reproductively isolated. Example: In humans, there are variations based upon the skin color, face size, height, etc. The variation is seen in genes among individuals but not genes are different.
Hence, different individuals of the same species have different traits because individuals have differences in their genes that result in protein variation. Hence, option A is correct regarding variation.

What are celestial bodies?A celestial object is an observable cosmic phenomenon that happens naturally. The terms "object" and "body" are frequently used synonymously in astronomy.
A celestial object, on the other hand, is a complex, less cohesively bonded structure that could include numerous bodies or even other objects with substructures, as opposed to a celestial body, which is a single, tightly bound, adjoining entity. Space objects like the Sun, planets, moons, and stars are referred to as celestial bodies or heavenly groups.
They are normally quite far away from us and are a part of the vast cosmos we inhabit. Such objects are scattered throughout the majestic night sky, and when viewed through a telescope, they reveal intriguing worlds of their own.
Therefore, Mercury, Mars, Venus, Earth, Neptune, Uranus, Saturn, and Jupiter Is smallest to largest.
