Explanation:
Dr. Nachman and his colleagues collected rock pocket mice across 35 kilometers of the Arizona Sonoran Desert, which included both dark, rocky lava outcrops and light, rocky, granite areas. They recorded substrate color, and coat-color frequencies for each location. Each site was separated from any of the others by at least eight kilometers. The researchers trapped a total of 275 mice. Their data are summarized below (numbers have been slightly modified for the purposes of this worksheet).
Field Data Summary
Collecting Site Substrate Color Number of Mice Phenotype Light Dark
1 Dark 22 3 19
2 Light 80 74 6
3 Light 22 19 3
4 Dark 28 3 25
5 Light 58 25 33
6 Dark 65 9 56
1. Calculate the overall frequencies of light-colored mice and dark-colored mice caught on light-colored substrates. [to 3 decimal places]
2. Calculate the overall frequencies of light-colored mice and dark-colored mice caught on dark-colored substrates. (to 3 decimal places)
3. Using the Hardy-Weinberg equation and data from the table above, determine the frequency of the three genotypes on the light, rocky, granite substrate. For genotype frequencies use three decimal places and for calculations using the allele frequencies, you must round the allele frequencies to two decimal places.
4. Using the Hardy-Weinberg equation and data from the table above, determine the frequency of the three genotypes on the dark, rocky lava substrate. (to 3 decimals). For genotype frequencies use three decimal places and for calculations using the allele frequencies, you must round the allele frequencies to two decimal places.
5. Which fur color seems to have the greatest overall selective advantage? Use data collected from both dark-colored and light- colored substrates to support your answer.
6.What environmental change gave a selective advantage for one coat color over another?
7. In a separate study, 76 rock pocket mice were collected from four different, widely separated areas of dark lava rock. One collecting site was in Arizona. The other three were in New Mexico. Dr. Nachman and colleagues observed no significant differences in the color of the rocks in the four locations sampled. However, the dark-colored mice from the three New Mexico locations were slightly darker than the dark-colored mice from the Arizona population. The entire Mc1r gene was sequenced in all 76 of the mice collected. The mutations responsible for the dark fur color in the Arizona mice were absent from the three different populations of New Mexico mice. No Mc1r mutations were associated with dark fur color in the New Mexico populations. These findings suggest that adaptive dark coloration has occurred at least twice in the rock pocket mouse and that these similar phenotypic changes have different genetic bases. How does this study support the concept that natural selection is not random?
8. To determine if the rock pocket mouse population is evolving, explain why it is necessary to collect fur color frequency data over a period of many years.
Answers
Answer:
1)
frequencies of light-colored mice ≅ 0.74 frequencies of dark-colored mice ≅ 0.262)
frequencies of light-colored mice ≅ 0.13 frequencies of dark-colored mice ≅ 0.873)
p² ≅ 0.02q² ≅ 0.742pq ≅ 0.244)
q² = 0.13 p² = 0.4 2pq = 0.465) The dark-colored fur seems to have the greatest overall selective advantage
6) Dark lava changed the color of the substrate, from light to dark.
7) Because to produce dark color, animals from the different regions suffered different mutations that drove them to have almost the same dark fur color.
8) To see if the mice population is evolving. If it is, there will be a change in the allelic and genotypic frequencies over the years. If it is not evolving, the frequencies will keep equal through the years.

RNA and DNA are two nucleic acids that differ in nitrogen bases. ACGUGA is the RNA base pair that will pair with TGCACT, of DNA. Thus, option D is correct.
What is complementary base pairing?The complementary base pairing has been defined as the pairing of the nucleotides with each other to form the RNA or DNA structures. The base pairs with each other through hydrogen bonding where the reaction occurs between the purines and pyrimidines.
The RNA and DNA structure differs as RNA is made of ribonucleic acid with four nitrogen bases, A, U, G, and C, whereas DNA is made of deoxyribonucleic acid with bases, A, T, G, and C. Both differ in sugar and one nitrogenous base.
According to Chargaff's base pairing rule the purines (adenine and guanine) pair with pyrimidines (cytosine, thymine, and uracil). A forms a double bond with T in DNA and U in RNA, and G forms triple bonds with C.
The given DNA sequence is: TGCACT
The RNA bases for the sequence will be: ACGUGA

food containing carcinogens cause food poison,cancer and effect our health negatively.it degrades the immunity power of us which makes us weak.if regulations is made people be awared and stop consuming those type of food.people start to consume good diet.Answer:
Yes. I believe that there should be government regulation against known carcinogens. Take food into consideration. Before President Roosevelt passed the first Food and Drug Act, mothers would quite literally feed their children formula that could have heroin in it or any unregulated substance, because companies could do so without any repercussions. Meat factories were dangerous and its no secret that there were a significant amount of rats that fell into the meat. After this act was passed in the United States, factories cleaned up their conditions and food became somewhat safe to eat. This act protected the consumer and made them aware of what they were literally consuming. Why is this different from government regulation against carcinogens? Did you know that bug spray can contain carcinogens? Old fridges? Granite countertops? Weedkiller? Because I did not. Consumers should be aware of the contents of the things they are buying. Corporations SHOULD be held responsible for putting customers in harms way. Government legislation should be passed to protect those who do not know better. Because we should not have to know better. We should already know.
Explanation:
In camellia plants, flower color is controlled by a single gene with codominant alleles. A camellia plants with red flowers (R) is crossed with a camellia plant with white flowers (WW). What are the expected phenotypes of the offspring of this cross?
O A. All will have both red and white flowers.
• B. All will have red flowers.
O c. Half will have red flowers and half will have white flowers.
• D. All will have pink flowers.
Answers
Half will have red flowers and half will have white flowers (option c).
In camellia plants, flower color is controlled by a single gene with codominant alleles. In this case, one parent plant has red flowers (R), while the other parent plant has white flowers (WW).
When two organisms with codominant alleles are crossed, both alleles are expressed equally in the offspring. Therefore, in this cross, the offspring will inherit one allele for red flowers (R) from the red-flowered parent and one allele for white flowers (W) from the white-flowered parent.
The possible combinations of alleles that the offspring can inherit are RW and RW.
When the alleles RW and RW combine, the resulting genotypes are RR (red-flowered) and RW (pink-flowered). However, since the allele for white flowers (W) is recessive to the allele for red flowers (R), the plants with the RW genotype will exhibit the dominant red flower phenotype.
Therefore, half of the offspring will have the RR genotype and display red flowers, while the other half will have the RW genotype and also display red flowers. None of the offspring will have the WW genotype, so there won't be any white flowers.
Hence, the expected phenotypes of the offspring of this cross are that half will have red flowers and half will have white flowers. Thus, the correct option is c.

What is Cellular respiration? Draw out the equation. How does it compare to Photosynthesis?
Answers
Cellular respiration is the breakdown of glucose and other molecules by cells to generate energy in the form of ATP. (adenosine triphosphate).
There are three steps to the process: glycolysis, the Krebs cycle, and oxidative phosphorylation.
Cellular respiration has the following molecular equation:
\(C_6H_{12}O_6 + 6O_2 - > 6CO_2 + 6H_2O + ATP\)
This equation represents the breakdown of glucose and oxygen to produce carbon dioxide, water, and ATP.
In contrast, photosynthesis is the process by which plants, algae, and some bacteria transform solar light energy into chemical energy in the form of glucose and other organic compounds.
The process is divided into two stages: light-dependent reactions and light-independent reactions. (also known as the Calvin cycle).
Although cellular metabolism and photosynthesis are diametrically opposed processes, they are also mutually beneficial. The reactants of one process are the results of the other.
For example, the oxygen created during photosynthesis is used by cells to produce ATP during cellular respiration, and the carbon dioxide produced during cellular respiration is used by plants to produce glucose during photosynthesis.

Answers
Viruses spread by infecting cells and replicating within them. There are several ways that viruses can spread from one person to another:
Direct contact: Viruses can be spread through direct contact with an infected person, such as through shaking hands or hugging.
Indirect contact: Viruses can also be spread through indirect contact, such as by touching a surface or object that has been contaminated with the virus and then touching one's face, mouth, or eyes.
Respiratory droplets: Some viruses, such as the virus that causes COVID-19, are spread through respiratory droplets that are produced when an infected person talks, coughs, or sneezes. These droplets can land in the mouths or noses of people who are nearby or be inhaled into the lungs.
Sexual contact: Some viruses, such as HIV and herpes, are spread through sexual contact.
Overall, viruses can spread through a variety of means, and the specific method of transmission can depend on the specific virus and the mode of infection.

92ml 3.0 fl oz what is the ratio
Answers
The ratio between 92 mL and 3.0 fl oz is 46 : 44, or it can be further simplified to 23 : 22.
To find the ratio between 92 mL and 3.0 fl oz, we need to convert the units to a common measurement. Let's convert 3.0 fl oz to milliliters (mL).
1 fluid ounce (fl oz) is equal to approximately 29.5735 milliliters (mL).
Therefore, 3.0 fl oz is equal to 3.0 * 29.5735 = 88.72 mL (rounded to two decimal places).
Now we can express the ratio between 92 mL and 88.72 mL:
92 mL : 88.72 mL
Simplifying the ratio by dividing both sides by the greatest common divisor, we get:
46 : 44
So, the ratio between 92 mL and 3.0 fl oz is 46 : 44, or it can be further simplified to 23 : 22.
