The Law of Segregation states that: Question 6 options: Dominant traits will segregate with other dominant traits Genes segregate equally into gametes Recessive traits always segregate together Genes do not influence each other with regard to sorting into gametes
Answer:
Genes segregate equally into gametes
Explanation:
Gregor Mendel, due to his contribution to genetics, is referred to as the FATHER OF GENETICS. Among his contribution is the principles that governs inheritance in organisms. One of those principles is LAW OF SEGREGATION.
LAW OF SEGREGATION states that the alleles of a particular gene will separate into gametes in an equal manner. For example, in a gene Aa, each gamete produced by the organism with this gene will contain either allele A or allele a in equal proportion.

Explanation:
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.

review the micrographs of cells shown in figure 8-3. what information about cells do these micrographs suggest, which might not be accurate?
Answer:
The micrographs of cells shown in figure 8-3. what information about cells do these micrographs suggest is explained below in details.
Explanation:
Micrographs are the intensified images collected from small microscopes. Cell micrographs are often obtained from tissue specimens and show a constant mass of cells and inside compositions that are difficult to distinguish individually. It provides accurate images of the exteriors of cells and whole plants that are not imaginable by TEM. It can also be practiced for particle counting and size resolution, and method control.

Can someone tell me why cell specialization is important for life on earth. Please Give some examples of why it is important as well.
Answer:
It is important because if not then life would not exist at all except maybe in single cells forms
Explanation:
The body is made of so many cells and without cell specialzation, the cells would not know what to do, they would all be the same. The liver is so different from the skin from the eyes, from the tongue, and so on. That is why we need it so our body can do what it is supposed to do.
Thatś only really one example but I hope it helps!

Enzymes can build up (synthesize) or break down (lysis) a product. Explain the picture below
Answer:
Enzymes speedup the chemical reaction.
Explanation:
Enzymes are the molecules which are responsible for speedup of the chemical reaction. In this picture, we can see substrate attached to the active site of the enzyme. This enzyme speedup the chemical reaction and products are formed after completion of chemical reaction. When the chemical reaction is over, the products detached from the enzyme and no decrease occurs in the size of enzyme.
