Why does the dna re-zip closed when the mrna is done being made?
The process of DNA replication involves the separation of the double helix strands and the creation of new complementary strands.
When the mRNA is being transcribed from the DNA, the enzyme RNA polymerase moves along the template strand of DNA, unwinding the double helix and creating a single-stranded RNA molecule. However, once the mRNA molecule is complete, the RNA polymerase enzyme and associated proteins dissociate from the DNA template strand and the DNA double helix reforms.
The re-zipping of the DNA double helix is facilitated by the complementary base pairing of the nucleotide bases adenine (A) with thymine (T) and guanine (G) with cytosine (C). These base pairs create hydrogen bonds that hold the two strands of the DNA double helix together. When the RNA polymerase and associated proteins are no longer bound to the DNA template strand, the complementary base pairing of the nucleotides allows the two strands to come back together and form a stable double helix structure.
In summary, the re-zipping of the DNA double helix after mRNA transcription is complete is due to the complementary base pairing of the nucleotide bases, which creates hydrogen bonds between the two strands of the DNA molecule.

How many years will it take to triple the population of a city
that is growing exponentially at a relative rate of growth of 7%
annually?
(Accurate to the nearest year.)
How many yean wir it take to triple the poculation of a city that is growing exponentially at a relative rate of growth of \( 7 \% \) annually? (Acrurute fo the nearet pear)
To determine how long it will take to triple the population using the formula for exponential growth, we can start with the equation P(t) = P0e^(rt), where P0 is the initial population, P(t) is the population after time t, r is the relative rate of growth, and e is the mathematical constant approximately equal to 2.71828.
In this case, we want to find the value of t when P(t) is three times P0, which can be expressed as 3P0. So, we have the equation 3P0 = P0e^(rt).
By taking the natural logarithm (ln) of both sides of the equation, we get ln(3) = ln(e^(rt)).
Using the properties of logarithms, ln(e^(rt)) simplifies to rt ln(e), and ln(3) can be written as ln(3)/ln(e^(rt)).
Given that r = 0.07 (as given in the problem), we can calculate t as follows:
t = ln(3)/(0.07) ≈ 9.90 years ≈ 10 years (approximately).
Therefore, it will take approximately 10 years to triple the population.

what is the thing hanging in the back of your throat
The little fleshy dangling ball in the back of your neck is your uvula. As a component of your soft palate, it aids in stopping food and fluids from entering your nose during swallowing. Additionally, it releases saliva to keep your mouth moist.
In the anatomy of vertebrates, the throat is the portion of the neck that faces the vertebrae internally. The pharynx and larynx are located there. The epiglottis, which separates the esophagus from the trachea (windpipe) and keeps food and liquids from being inhaled into the lungs, is a crucial component of it.
The tonsils, pharyngeal muscles, trachea, esophagus, nasopharyngeal tonsil, tonsils, palatine uvula, and vocal cords are all present in the throat. The hyoid bone and the clavicle are the two bones that make up a mammal's throat. Sometimes people equate the "throat" with the fauces.

syphillis is a sexually transmitted infection caused by the bacterium treponema pallidum pallidum. treponema pallidum pallidum requires organic compounds as both an energy source and a carbon source. which feeding strategy most accurately describes that of this bacterium?
The feeding strategy that most accurately describes Treponema pallidum pallidum is Chemoorganoheterotroph. Chemoorganoheterotrophs are organisms that obtain both energy and carbon from organic compounds, such as sugars, amino acids, and fatty acids.
Treponema pallidum pallidum is unable to synthesize its own organic compounds and must acquire them from its environment, which it uses as an energy and carbon source. The bacterium is not able to use inorganic compounds as a source of energy or carbon, so it cannot be described as a chemolithotroph or chemolithoautotroph. It is also not an autotroph, which uses carbon dioxide as a source of carbon to synthesize its own organic compounds. Chemoheterotrophs are organisms that rely on organic molecules, such as sugars, amino acids, and fatty acids, for both energy and carbon. They break down these molecules through cellular respiration, using the energy released to drive metabolic processes and synthesize essential molecules.

Answer:
Due to different reproduction methods.
Explanation:
Organisms from eubacteria, plantae and animal kingdom are used different reproductive strategies which leads to genetic diversity. Bacteria use asexual reproduction which produces identical offspring while on the other hand, plants and animals use sexual reproduction that produces offspring that is different from plants which leads to variation in the organism so that's why we can say that different reproductive strategies is responsible for genetic diversity.

A 6-year-old African boy who had recently immigrated to the United States from Liberia was taken to the emergency department because of a high fever. Physical examination showed bilateral syndactyly and contractures of the fingers. His temperature was 100 degrees F. A CBC was ordered.
Laboratory data: RBC 2.1 X 1012/L Hematocrit 18% Hemoglobin 6.0 g/dL WBC 1.31 x 109/L Platelets 45,000 Questions:
1. What do the laboratory results suggest?
2. Is the boy’s physical appearance suggestive of a hematological abnormality?
3. What is the cause of Fanconi’s anemia?
4. What innovative treatments are available to patients with Fanconi’s anemia?
The laboratory results suggest that the 6-year-old African boy has anemia and thrombocytopenia (low platelet count).
The combination of bilateral syndactyly (fusion of fingers) and contractures of the fingers, along with the laboratory results, suggests that the boy may be experiencing complications related to sickle cell disease (SCD). SCD is a genetic disorder characterized by abnormal hemoglobin, known as hemoglobin S, which causes red blood cells to become sickle-shaped and less flexible.
The anemia seen in the laboratory results is consistent with SCD due to the chronic destruction of the sickle-shaped red blood cells and their shortened lifespan. The low platelet count could be a result of the ongoing hemolysis (breakdown of red blood cells) and/or the trapping of platelets in small blood vessels due to vaso-occlusive events.
