( Atoms) are the basic building blocks of all matter. It was once thought that an atom was the smallest particle of matter but
scientists discovered that there are smaller subatomic particles that make up the atom. There are (Three) basic subatomic particles:
the (proton), the (neutron), and the (electron) the number of protons is called the (atomic number) . The proton is the particle that is used to identify the (element). Every element has a specific number of protons. No two elements will have the (same) number of protons. For example: an atom that has six protons will be a (carbon) atom, (All) carbon atoms will have six protons. If you have an atom that has (two) protons, you have an atom of helium (like the gas that we fill (balloons) with). No other element will have two protons.

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.

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.

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).

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.
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.

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.
