why Guainen (G) is always paired with cytosine (C) with triple bond and so Adenine with Thymine with double bonds?
Answers
Answer:
In DNA and RNA, guanine forms three hydrogen bonds with cytosine. Three bonds are formed between these bases as a result of the fact that guanine possesses two nitrogen and one oxygen atoms that can form hydrogen bonds. Given the spatial restrictions of the double helix, which call for there to be one purine and one pyrimidine in each base pair, A always pairs with T and G always pairs with C as these are the only combinations that for hydrogen bonding to take place.

The property of muscle tissue that allows an impulse to travel down the entire length of the cell membrane is Elasticity.
What is Muscle elasticity ?Stretching a muscle to its complete range of motion without being constrained is possible thanks to tissue elasticity. The body has a variety of tissues, such as connective tissues and soft tissues. Tissues frequently become constricted and inelastic, increasing muscle tension and pain.
Muscle tissue is made up of cells with the unique capacity to constrict or shorten in order to cause movement of the bodily components. High levels of cells and blood vessels can be found throughout the tissue.

What is a possible result of an increased amount of CO2 in the atmosphere?
Answers
Answer:
There are no options to this question, however, it can be answered using general knowledge. The answer is GLOBAL WARMING
Explanation:
Carbon dioxide, commonly called CO2, is one of the gaseous constituent of air. It is considered to be the most important greenhouse gas i.e. gases that have the ability to trap heat from the surrounding atmosphere. Due to this ability, CO2 in addition to other gases like methane are known to contribute to a phenomenon called GLOBAL WARMING.
GLOBAL WARMING is an increase in the atmospheric temperature of the Earth due to the effect of greenhouse gases. Global warming is a concern for the world populace, hence, an increase in the concentration of gases like CO2 in the atmosphere will lead to GLOBAL WARMING (an increase in Earth's atmospheric temperature).

In the report, the biologist is describing a population in Florida. A population is a group of organisms of the same species that live in a particular area and can interbreed with one another. In this case, the rattlesnakes are a population of the same species that live in Florida and can reproduce together. The report includes statistics about the population's size, breeding rate, and characteristics, which are all typical of a population analysis. A community refers to all the different populations of species that coexist in a particular area, while a biome refers to a large geographic area with similar climate and vegetation. An organism refers to an individual living thing.
Look at the incomplete equation below. What does Ek represent?
Answers
In the given equation, Ek represents the kinetic energy of an object.
Kinetic energy (Ek) is a form of energy associated with the motion of an object. It is dependent on both the mass (m) and the velocity (v) of the object.
The equation Ek = (1/2)m\(v^2\) represents the formula to calculate the kinetic energy of an object.
The symbol "Ek" is commonly used to represent kinetic energy in scientific calculations and equations. By plugging in the values of mass and velocity into the equation, one can calculate the amount of kinetic energy possessed by the object.
The kinetic energy of an object increases with both its mass and velocity. As the mass increases, the object has more particles in motion, contributing to higher kinetic energy.
Similarly, as the velocity increases, the speed at which the object moves also increases, resulting in greater kinetic energy.
Therefore, understanding and calculating kinetic energy is important in various scientific and engineering applications, such as studying the movement of objects, analyzing collisions, or designing efficient systems.

If you leave some uranium-235 lying around, it will radioactively decay into lead-207. The half-life for this decay is 704 million years. If we measure the uranium-235 in the oldest rocks on Earth and find that 1/64th of the expected amount is present, we can calculate a minimum age for the Earth. First figure out how many half-lives would have passed to account for 1/64 being left. Then use this number to calculate the age of the rock (and the Earth).
Answers
Answer:
To calculate the minimum age of the Earth, we can use the fact that the amount of uranium-235 remaining after a certain number of half-lives is given by the equation:
N = N0 * (1/2)^n
where N is the current amount of uranium-235, N0 is the initial amount of uranium-235, and n is the number of half-lives that have passed.
If we assume that the initial amount of uranium-235 in the oldest rocks on Earth was N0, and that 1/64th of the expected amount is present, then the current amount of uranium-235 is:
N = N0 * (1/64)
We can set this equal to the amount of uranium-235 that would remain after n half-lives:
N = N0 * (1/2)^n
N0 * (1/64) = N0 * (1/2)^n
Dividing both sides by N0 gives:
1/64 = (1/2)^n
To solve for n, we can take the logarithm of both sides of the equation:
log(1/64) = log((1/2)^n)
Using the logarithmic property that log(a^b) = b*log(a), we can simplify the right side of the equation:
log(1/64) = n*log(1/2)
Dividing both sides by log(1/2) gives:
n = log(1/64) / log(1/2)
n ≈ 6
Therefore, 6 half-lives have passed since the initial amount of uranium-235 was present in the oldest rocks on Earth.
The age of the Earth can be calculated by multiplying the number of half-lives by the half-life time:
Age of the Earth = n * half-life time
Age of the Earth = 6 * 704 million years
Age of the Earth ≈ 4.2 billion years
Therefore, the minimum age of the Earth is approximately 4.2 billion years.

A major cause of aneuploidy is “chromosome instability.
Does aneuploidy cause mutation?Aneuploidy impairs the karyotype and thus the species, independent of mutation because it buys highly conserved teams of proteins that segregate, synthesize and repair chromosomes. Likewise, it destabilizes genes.
We conclude that the transition of stable diploid to rocky aneuploid cell species is the primary cause of preneoplastic and neoplastic genomic insecurity and of cancer and that mutations are secondary.
So we can conclude that Aneuploidy: Extra or absent chromosomes. Changes in a cell's genetic material are called mutations.

If the sequence of an mRNA moving through the ribosome has the sequence 5'AUGCCAGCGGAUCGC3', what is the sequence of the polypeptide produced from translating this segment
Answers
Answer:
MPADR (methionine-proline-alanine-aspartic acid-arginine)
Explanation:
Translation is the mechanism for which a protein is synthesized from the information encoded in the messenger RNA (mRNA). The mRNA is a single-stranded molecule that consists of a chain of nucleotides, where three-letter combinations of nucleotides 'or codons' specify the order of the corresponding amino acids in the polypeptide chain. The ribosome reads the mRNA by one codon at a time and thus translates this information into a polypeptide, where each codon is specific for one amino acid. In this code, the start codon is AUG (which is read as Methionine), while stop codons can be UAG, UAA, and UGA.
