If the adenine in the 15th position of the sequence is changed to a guanine, the person does not have CF. However, if the thymine in the 14th position is changed to a cytosine the person does have CF. What are some reasons this might occur?
Answers
Answer:
Explanation:
Mutation is a sudden heritable change in the genome of an organism.
Substitution is a form of mutation whereby a base pair is been substitued for by another base pair resulting in a serious damage.
Codon are three alphabeth coding for a particular amino acid.
When substitution occurs in a base pair and the replacement forms a protein that has the same function as the one that was removed there will be no observable in the phenotype. Hence, If the adenine in the 15th position of the sequence is changed to a guanine, the person may not have cystic fibrosis.
But when a particular base pair is substituted for and an entirely new protein or amino acids results with a different functions and structure it could lead to a serious damage or healthy issue. Hence, If the adenine in the 15th position of the sequence is changed to a guanine, the person does have cystic fibrosis.

Alice was participating in a photosynthesis lab for science class. The lab procedures instructed Alice to prepare a test tube containing water, a sprig of elodea (a common aquarium plant), and 10 g of sodium bicarbonate (NaHCO3). She was then instructed to place the test tube in front of a strong light source for one minute. Alice noticed tiny bubbles forming on the leaves of the elodea. What is the most logical explanation for why Alice saw bubbles forming on the leaves of the elodea?Group of answer choicesThe bubbles formed as a result of the hydrogen from the sodium bicarbonate mixture dissolving the elodea leaves.The bubbles formed from the release of water molecules from the elodea leaves.The bubbles formed as the elodea plant released oxygen from the elodea leaves.The bubbles formed as the elodea plant released carbon dioxide from the elodea leaves.
Answers
Step 1.
Write down the experiment data.
- tube containing water;
- alodea (photosynthetic organism);
- 10 g of sodium bicarbonate;
- light source.
Step 2.
Why bubbles are formed on the leaves of the alodea?
The experiment have all the condictions for photosynthesis, since it provides: water (that is in the tube), CO2 (because of the dissolved sodium bicarbonate), light (because of the string light source). Therefore the most ogical explanation for Alice experiment results is: the bubbles formed as the elodea plant releases oxygen from the elodea leaves, that because with all the elements in the experiment the plant can do a normal photosynthetic process that way realing oxygen in the tube and forming bubbles of "air".
during what phase of meiosis do homologous chromosomes line up in the center of the cell
Answers
Homologous chromosomes line up in the center of the cell at metaphase I.
MEIOSIS:
Meiosis is a type of cell division in which a single cell produces four genetically different daughter cells. Meiosis reduces the chromosome number of the daughter cells by half. Meiosis occurs in a two step division process namely meiosis I and meiosis II. Meiosis generally consists of four stages namely Prophase, Metaphase, Anaphase and Telophase. Metaphase is the stage where chromosomes line up at the cell's equator or cell plate. However, in meiosis I, homologous chromosomes line up while in meiosis II, sister chromatids line up. Therefore, homologous chromosomes line up in the center of the cell at metaphase I.Learn more at: https://brainly.com/question/21888742?referrer=searchResults
population of bacteria is growing according to the equation P(t)=1000e0.12t, where P(t) is the population and t is the time in hours. Estimate when the population will reach 5000 . Round to the tenths. Provide your answer below:
Answers
The estimated time it will take for the population to reach 5000 bacteria is approximately 13.4 hours.
To estimate when the population will reach 5000 bacteria, we can set up the equation P(t) = 5000 and solve for t.
The given equation for population growth is P(t) = 1000e^(0.12t). To solve for t, we can substitute 5000 for P(t):
5000 = 1000e^(0.12t)
To isolate the exponential term, we can divide both sides of the equation by 1000:
5 = e^(0.12t)
Next, we can take the natural logarithm (ln) of both sides to remove the exponential:
ln(5) = ln(e^(0.12t))
Using the property of logarithms, ln(e^(0.12t)) simplifies to 0.12t:
ln(5) = 0.12t
Now, we can solve for t by dividing both sides by 0.12:
t = ln(5) / 0.12
Using a calculator, we find that ln(5) is approximately 1.6094. Dividing this by 0.12 gives us an approximate value for t:
t ≈ 1.6094 / 0.12 ≈ 13.4117
Rounding to the tenths place, the estimated time it will take for the population to reach 5000 bacteria is approximately 13.4 hours.

Answers
The photosynthetic bacterium consumed by the predatory cell that evolved into an organelle is called chloroplast.
The process of endosymbiosis led to the incorporation of a photosynthetic bacterium into a larger eukaryotic cell, giving rise to the chloroplast organelle found in plants and algae. The bacterium evolved into a specialized organelle that performs photosynthesis, using light energy to synthesize organic compounds. The chloroplast has its own DNA and ribosomes, which are similar to those found in bacterial cells, providing evidence for the endosymbiotic origin of the organelle. The chloroplast is also surrounded by a double membrane, which is thought to represent the remnants of the ancestral bacterial cell wall. Overall, the evolution of the chloroplast through endosymbiosis has played a critical role in the development of photosynthetic organisms and the ecosystems they support.

Watson and Crick used all of the provided information, including LinusPauling's conclusion about hydrogen bonds, Chargaff's rules, the width of the molecule observed in Dr. Franklin's X-ray images, and the spiral nature of the molecule.
Watson and Crick utilized all of the mentioned information during their construction of the DNA model. Linus Pauling's conclusion about hydrogen bonds was crucial because it provided insights into the forces holding the DNA bases together. Chargaff's rules, which stated that the amount of adenine equaled the amount of thymine and the amount of cytosine equaled the amount of guanine, were fundamental for understanding base pairings within the DNA structure.
The width of the DNA molecule, determined by examining Dr. Franklin's X-ray crystallographic images, played a significant role. The X-ray images indicated that DNA had a consistent diameter, suggesting a helical structure. This observation supported the notion of a spiral nature for the DNA molecule, which Watson and Crick incorporated into their model.

5. What are virus hoaxes? Why are the hoaxes sometimes more dangerous than an actual virus?
Answers
Answer:
An actual computer virus is a malicious software, often known as malware, that can harm a computer and its users.
Virus hoaxes are false or misleading information about viruses that circulate through various communication channels.
They can be more dangerous than actual viruses due to their ability to spread quickly, cause panic, and undermine effective public health measures.
Virus hoaxes are deceptive messages or claims that often exaggerate the severity or impact of a particular virus. They can be spread through social media, email chains, or word of mouth. These hoaxes may include misinformation about symptoms, transmission methods, or false remedies, leading people to take ineffective or even harmful actions.
What makes virus hoaxes particularly dangerous is their potential to create panic and misinformation at a rapid pace. The viral nature of social media and other communication platforms allows these hoaxes to reach a wide audience within a short period. As a result, people may make decisions based on false information, such as avoiding necessary medical treatment, taking unnecessary precautions, or spreading fear and misinformation to others.
Moreover, virus hoaxes can undermine public health efforts by diverting attention and resources from legitimate preventive measures. They can erode trust in healthcare authorities and disrupt the dissemination of accurate information, making it harder for individuals to make informed decisions and follow recommended guidelines.
This can have severe consequences, especially during outbreaks or pandemics, where timely and accurate information is crucial for public safety. Therefore, it is essential to verify the credibility of information and rely on trusted sources to mitigate the risks associated with virus hoaxes.

which of the following occur as a result of fertilization?
multiple select question.
crossing over haploid organism diploid organism zygote
Answers
The result of fertilization is the formation of a **diploid organism** and a **zygote**.
Fertilization is the process where a sperm cell and an egg cell (both haploid) fuse to form a zygote, which is a single cell with a diploid chromosome number. A diploid organism has two complete sets of chromosomes, one from each parent. This is in contrast to a haploid organism, which has only one set of chromosomes. Crossing over is not a direct result of fertilization; it occurs during meiosis, the cell division process that produces haploid gametes (sperm and egg cells). The zygote formed through fertilization will eventually undergo multiple rounds of cell division and differentiation to develop into a multicellular organism.

Site 1: "Stages of Sleep"
Describe the body's typical state during the first stage of sleep. (Site 1)
Answers
The first stage of sleep is defined as the period between wakefulness and sleep, and it is characterized by a decrease in brain activity and muscle tone.
The body's typical state during the first stage of sleep includes a decrease in muscle tone, a slowing of brain waves, and a decrease in eye movement. During this stage, the brain waves are generally alpha waves, which are slower than those that occur during wakefulness, but faster than those that occur during deeper stages of sleep.The first stage of sleep is often referred to as light sleep because it is easy to be awakened from this stage.
It usually lasts for about 5-10 minutes, and during this time, the body's temperature begins to decrease, and the heart rate and breathing rate begin to slow down. In addition to these changes, the body may also experience other physiological changes, such as a decrease in blood pressure and a decrease in the production of stress hormones.
The first stage of sleep is an important part of the sleep cycle because it is the stage that helps to prepare the body for deeper stages of sleep. During this stage, the body begins to relax, and the mind begins to slow down. This allows the body to enter deeper stages of sleep, where the brain waves slow down even further, and the body's muscles become even more relaxed. Overall, the first stage of sleep is an important part of the sleep cycle, and it is necessary for the body to enter deeper stages of sleep so that it can rest and rejuvenate.
