14. The organic compounds can be listed in order from simple to most complex is Carbs (simplest), Lipids, Proteins, and Nucleic acids (most complex). 15. The organic compound your body use for stored energy is lipids. 16. The organic compound your body use for quick energy is carbohydrates
Carbohydrates are made up of monosaccharides, disaccharides, and polysaccharides. Lipids, on the other hand, have a more complex structure and are classified into four main groups; waxes, fats, oils, and steroids.Proteins are the next level, and they are made up of amino acids that are connected by peptide bonds. Nucleic acids, which are the most complex of all, are made up of nucleotides and can be found in two types; RNA and DNA.
Lipids are hydrophobic, which means they can be stored for a long time in a small space, the energy produced by lipids is used by the body for metabolic processes, insulation, and other essential processes. Carbohydrates are easily broken down to produce energy for the body to use. Once the body has enough glucose (simple sugar), it converts it to glycogen, which can be stored in the liver and muscles. When the body needs quick energy, it breaks down glycogen to produce glucose, which is used to fuel the cells.
So therefore the organic compounds can be listed in order from simple to most complex is Carbs, Lipids, Proteins, and Nucleic acids, then lipids are the organic compound that the body uses to store energy and carbohydrates are the organic compound used by the body for quick energy.

Explain the similarities and differences between substitutions, insertions, and deletions
Answer:
Substitutions, insertions, and deletions are types of genetic mutations that can occur in DNA or RNA sequences.
A substitution, also known as a point mutation, is a change in a single nucleotide base pair in the DNA or RNA sequence. There are three types of substitutions: silent, missense, and nonsense mutations. A silent mutation is a substitution that does not result in a change in the amino acid sequence of the protein that is produced. A missense mutation is a substitution that does result in a change in the amino acid sequence, potentially affecting the function of the protein. A nonsense mutation is a substitution that creates a premature stop codon, resulting in a truncated protein.
An insertion mutation occurs when one or more nucleotide base pairs are added to the DNA or RNA sequence, causing a shift in the reading frame. This can result in a frameshift mutation, which changes the way the entire sequence is read and can affect the protein produced.
A deletion mutation occurs when one or more nucleotide base pairs are removed from the DNA or RNA sequence, also causing a frameshift mutation. Like an insertion, a deletion can affect the protein produced, depending on where in the sequence it occurs.
In summary, substitutions, insertions, and deletions are all types of genetic mutations that can occur in DNA or RNA sequences. Substitutions involve a change in a single nucleotide base pair, while insertions and deletions involve the addition or removal of one or more base pairs, respectively. Insertions and deletions can result in a frameshift mutation, which changes the reading frame of the sequence and can have significant effects on the protein produced.

Consider the following scenario: A farmer walks out into his field one morning and notices a black cloud moving toward him - fast. To his horror, the cloud is made up of locusts, relatives of the grasshopper that are incredibly voracious plant-eaters. As the insects start descending on his field, he bolts into an old shed nearby and stumbles over a bucket labeled "BUG DEATH", complete with a hose and rusty sprayer. He grabs the bucket and sprays his field, where the locusts promptly shrivel up and die. The farmer's crop is saved except for the portion that the mice eat during the summer. Next year, the farmer notices that unfortunately there are lots of mice around but not many owls, falcons, or snakes. Explain what likely led to the change in the size of the mouse, owl, falcon, and snake populations. Also, how could you find out what substance was in the "BUG DEATH" bucket? (The farmer threw away the empty bucket, so you cannot test the bucket anymore.)
The change in the size of the mouse, owl, falcon, and snake populations can likely be attributed to the use of the pesticide from the "BUG DEATH" bucket.
Mouse population: The mice population increased because the pesticide likely eliminated a significant portion of their natural predators, such as owls, falcons, and snakes. With fewer predators, the mouse population was able to thrive and multiply.
Owl, falcon, and snake populations: The populations of these predator species likely decreased because the pesticide either directly affected them or indirectly affected their food source. If the pesticide had toxic effects on the owls, falcons, or snakes, it could have led to a decline in their population. Alternatively, if the pesticide had a detrimental effect on the insects that these predators feed on, their food supply would have been reduced, leading to a decline in their numbers.
To determine what substance was in the "BUG DEATH" bucket, since the empty bucket is no longer available for testing, several approaches can be considered:
Consult the product label: If the pesticide was a commercially available product, there might be records or documentation regarding its composition and active ingredients. The farmer could try to recall the brand or seek information from the manufacturer or local agricultural authorities.
Analyze residue samples: The farmer could collect soil or plant samples from the treated area and send them to a laboratory for analysis. The laboratory could perform tests to identify any pesticide residues that might be present, helping to determine the substance used.
Seek expert assistance: The farmer could consult with agricultural experts or local extension services who may have knowledge or resources to identify common pesticides used in the area based on the observed effects and historical practices.
It's important to note that the use of pesticides should always be approached with caution and in compliance with relevant regulations and guidelines to minimize potential harm to non-target organisms and the environment.

what is the function of the capillaries? to temporarily store blood that isn't being circulated to carry blood toward the heart to act as a zone of diffusion between blood and tissues to carry blood away from the heart
The function of capillaries is to act as a zone of diffusion between blood and tissues.
Capillaries are tiny, blood vessels with thin walls that link arteries and veins. Because of the thinness of its walls—just one cell—the blood and tissues around it may exchange nutrition, oxygen, and waste products.
Throughout the body, capillaries are essential for the supply of nutrients and oxygen to cells. Oxygen and nutrients permeate from the blood and into the surrounding tissues as it passes through capillaries. Furthermore, wastes like carbon dioxide and metabolic byproducts seep into the blood from the tissues and are then transported elsewhere for processing and removal.
In conclusion, capillaries' main job is to serve as a point of exchange between blood and tissues, enabling the delivery of nutrients and oxygen as well as the elimination of waste.

c. Adding animal genes into a plant
Explanation:
Adding animal genes into a plant represents a modern biotechnology technique that raises potential ethical issues. This technique, called transgenic or genetic engineering, involves inserting genes from one organism into another to produce a desired trait. In the case of adding animal genes into a plant, this could involve creating crops that are more resistant to pests or herbicides, or that produce certain pharmaceuticals.
This technique raises ethical concerns because it involves manipulating the genetic makeup of living organisms, which could have unintended consequences for the environment or human health. For example, the introduction of a new gene into a plant could cause unintended effects, such as allergies or toxicity. There are also concerns about the potential for genetic engineering to be used for non-food purposes, such as creating designer pets or even humans with specific traits.
Crossbreeding two different plants, using bacteria in the making of food, and transferring blood from one person to another are all examples of techniques that have been used for centuries or even millennia and are generally considered to be safe and ethical. However, it is worth noting that any technique, including these examples, could raise ethical concerns if used in a particular way or context.
A baker has created a new strain of yeast which contains no cytochrome c gene and, thus, no cytochrome c protein. This will affect what the yeast strain can do to obtain energy. Making bread is an aerobic process for the yeast.
Will this new strain of yeast obtain more or less free energy from glucose in its growing medium?
A. More because it does not have to make cytochrome c and has more resources to give to obtaining energy
B. Less because cytochrome c is key to the electron transport chain
C. More because making cytochrome c uses up ATP
D. Less because cytochrome c directly produces ATP in the cytoplasm
PART 2: What will there be less of in these cells than in standard yeast?
A. ATP
B. Membranes
C. Mitochondrial membranes per mitochondrion
D. Glucose
Part 1: Yes, this new strain of yeast obtains more or less free energy from glucose in its growing medium because of (B) Less because cytochrome c is key to the electron transport chain.
Part 2: Yes, there is less of in these cells than in standard yeast, because of (A) ATP.
Part 1: In order for the electron transport chain to function properly, cytochrome c is a necessary component. Without it, the reduction and oxidation of iron atoms that could change ferrous ions into ferric ions won't happen. As a result, the creation of ATP and the electron transport chain as a whole will be disrupted. Therefore, the yeast's anaerobic fermentation process will not result in the creation of any usable kind of energy.
Part 2: When using regular yeast to make bread, the reaction begins as an aerobic process before transitioning to an anaerobic phase once the oxygen is used up. A new strain of yeast lacking the cytochrome c gene and cytochrome c protein was developed by a baker. This will have an impact on the yeast strain's ability to produce ATP.

Non-Smokers 50 550
b) Number of people who smoked cigars and did not have tongue cancer: 450.
c) Number of people who did not smoke cigars and did not have tongue cancer: 550.
d) The odds ratio is 11.
e) Interpretation: Cigar smokers are 11 times more likely to develop tongue cancer compared to non-smokers.
a) The 2x2 table for the study is as follows:
Tongue Cancer No Tongue Cancer
Cigar Smokers 450 450
Non-Smokers 50 550
b) The number of people who smoked cigars and did not have tongue cancer is 450.
c) The number of people who did not smoke cigars and did not have tongue cancer is 550.
d) To calculate the odds ratio, we use the formula: (ad)/(bc), where a is the number of cigar smokers with tongue cancer, b is the number of non-smokers with tongue cancer, c is the number of cigar smokers without tongue cancer, and d is the number of non-smokers without tongue cancer. In this case, the odds ratio is:
(450 * 550) / (50 * 450) = 550 / 50 = 11
e) The odds ratio of 11 indicates that individuals who smoke cigars are 11 times more likely to develop tongue cancer compared to those who do not smoke cigars. This suggests a strong association between cigar smoking and tongue cancer. It is important to note that the odds ratio only indicates the strength of association and does not establish causation. Other factors, such as lifestyle, genetics, and other smoking habits, may also contribute to the development of tongue cancer. Further research and analysis would be required to determine the causal relationship between cigar smoking and tongue cancer.

(b) To genetically engineer the original cell so that it would glow, the scientists had to obtain a suitable
gene.
(i) Describe the stages that a scientist would complete to obtain this gene.
Answer: See Below
Explanation:
1. The scientist would need to identify the gene for a protein that would make it glow. For example Aequorea victoria, the jellyfish that produces green fluorescent protein (GFP) is the most common type of fluorescent tag use in biotechnology. This would be done by completing genetic sequencing to identify the gene of interest from the jellyfish cell.
2. The gene could then be amplified through PCR. Assuming this is a bacterial cell, a vector such as pUC19 could be used. The vector and the PCR amplified product would have to be digested. A double digest is recommended to ensure the gene inserts in the proper conformation.
3. Heat shock the plasmid into the cell and proceed on to Blue/White screening to identify which cells contain the gene of interest. You can then isolate and grow the culture containing the GFP gene and induce with IPTG to produce the protein that would make it glow.
Alternatively you could buy a pre-made plasmid from AddGene containing the GFP gene for 75$, complete a miniprep on the cells and heatshock. Either way works.
