A fixed pattern of long and short notes that is repeated or varied is known as a. a cantus firmus. b. a rhythmic mode. c. a melisma. d. organum.

Answers

Answer 1

A cantus firmus (Latin for "fixed song") is a pre-existing melody used as the basis of a new composition. So option a is correct.

It is most commonly found in the form of a long and slow-moving melody, which is then repeated or varied by the composer. The cantus firmus was a popular form of composition in the Middle Ages and Renaissance eras, used by composers such as Josquin des Prez, Palestrina, and Orlando di Lasso.

A rhythmic mode is a pre-existing pattern of strong and weak beats used as the basis of a new composition. It is a more varied form of composition than the cantus firmus, as it contains not only long and slow-moving notes, but also fast and light notes. The rhythmic mode is found in music from many different cultures, such as African, Indian, and Latin American. Composers such as Bach, Beethoven, and Mozart used rhythmic modes in their compositions.

A melisma is a type of vocal ornamentation in which several notes are sung on the same syllable. It is a popular form of singing in many musical styles, including jazz, gospel, and classical. Melismatic singing is often used to express emotion or add color to a song. Composers such as Handel and Vivaldi used melismatic singing in their compositions.

What causes populations to lose genetic diversity due to chance?

Answers

Stochastic sampling error (i.e., genetic drift) causes populations to lose genetic diversity due to chance.

Genetic drift is a result of sampling error because individuals are randomly chosen when a population is sampled. A random selection is one in which each member of the population has an equal chance of being chosen.

The random change in allele frequencies caused by stochastic sampling of alleles from the previous generation is known as genetic drift (independent of demographic stochasticity).

The variety of various inherited features within a species is referred to as genetic diversity. There would be many people with a wide range of diverse traits in a species with significant genetic diversity. For a population to adapt to changing surroundings, genetic variety is essential.

A molecule that can be used as a molecular clock has a neutral mutation rate of one mutation per 40 million years. How many years ago did two species share a common ancestor if the molecules found in these two species differ by a total of eight mutations

Answers

The two species must have shared a common ancestor 320 million years ago, since the neutral mutation rate of the molecular clock is one mutation per 40 million years and the two species differ by a total of eight mutations.

A molecular clock is a tool used by scientists to estimate the time since two species have shared a common ancestor. This is done by measuring the number of genetic differences, or mutations, between the two species. The molecular clock is based on the assumption that the mutation rate is constant.

In this case, we know that the neutral mutation rate of the molecule being used as a molecular clock is one mutation per 40 million years. This means that for two species to have a difference of eight mutations, it must have been at least 320 million years ago that they shared a common ancestor.

To arrive at this conclusion, we can use the following formula:

Number of mutations × Neutral mutation rate = Time since common ancestor

In this case, 8 mutations × 40 million years = 320 million years. This means that two species must have shared a common ancestor at least 320 million years ago for them to have a difference of eight mutations.

The molecular clock can be a powerful tool for scientists to estimate the time since two species have shared a common ancestor. In this case, the neutral mutation rate of the molecule was known and used to calculate that two species must have shared a common ancestor at least 320 million years ago.

What is the best example of a Mendelian trait in humans?

Answers

The best example of a Mendelian trait in humans is phenylketonuria. This illness is an illustration of a Mendelian trait since it is passed down from parents to children when both parents have heterozygous (Aa) and homozygous (Aa) circumstances.

Mendelian qualities are determined by all of Mendel's postulated Laws of Inheritance and are traits that are transferred from parents to children through dominant and recessive alleles of a gene. The lack of an enzyme that turns the amino acid phenylalanine into tyrosine is the root cause of the autosomal recessive inherited disorder. As a result, the amino acid builds up and is converted into the toxic form of phenyl pyruvic acid, which builds up in the brain of the person and causes r-e-t-a-r-d-a-t-i-o-n.

What happens to the light when you look at a green object?

Answers

When you look at a green object, the object reflects green light and absorbs other colors of the visible spectrum. The green light is then transmitted to your eye, where it is focused by the lens onto the retina.

The retina contains specialized cells called rods and cones that are sensitive to different wavelengths of light. The cones in the retina are responsible for color vision and are most sensitive to different colors in the visible spectrum, and when the green light reaches the cones, it triggers a neural signal that is sent to the brain, where it is interpreted as the color green. The absorbed light colors are not reflected and are green absorbed by the object, they are not transmitted to green the eye, so they are not perceived by the observer.

How can katey and amanda's amino acid sequence be the same and yet they may have a differences in their DNA?

Answers

Answer: Two people can have different DNA sequences but these sequences can code for the same amino acids due to the redundancy of the genetic code in which two different codons can code for the same amino acid.

Explanation:

The genome of an organism is found in a molecule called DNA (deoxyribonucleic acid). The main function of this DNA molecule is the long-term storage of information to build other components of cells, such as proteins and RNA molecules (ribonucleic acid); and the portion of the genome that codes for a protein or RNA is known as a gene. These protein-coding genes are composed of trinucleotide units called codons, each of which codes for an amino acid. For a protein whose sequence is encoded in the nucleotides of DNA to be synthesized, that DNA molecule must first be transcribed into a molecule called messenger RNA, and this molecule is used for a process called translation or protein synthesis. The sequence of the genetic material is composed of four distinct nitrogenous bases, which are represented by letters in the genetic code:

Adenine (A)Thymine (T)Guanine (G) Cytosine (C)Uracil (U) instead of T in RNA

The genetic code is the set of rules that defines how a sequence of nucleotides in RNA is translated into a sequence of amino acids in a protein. This code is common to all living things, which shows that it has had a unique origin and is universal. So, the code defines the relationship between each sequence of three nucleotides (codon) and each amino acid.  The number of possible codons is 64, of which 61 code for amino acids (one of them being the start codon, AUG) and the remaining three are stop sites (UAA, UAG, UGA). The codon sequence determines the amino acid sequence in a particular protein, which will have a specific structure and function.

However, the genetic code has redundancy but no ambiguity. For example, two different codon can code for the same amino acid, and the differences between codons encoding the same amino acid have differences in the third position. This is explained by the wobble effect, where the same anticodon (present in the transfer RNA that loads with the amino acid and interacts with the codon in the messenger RNA) can establish interaction with different codons, which differ in their third base. This is why, in general, tolerance to change at this position is greater than at the first and second positions, and therefore tends to be less represented in the case of variations that result in pathologies.

Thus, two people can have different DNA sequences but these sequences can code for the same amino acids due to the redundancy of the genetic code in which two different codons can code for the same amino acid.

The skinny partitions of the glomerulus permit smaller molecules, wastes, and fluid—often water, into the tubule. Larger molecules, together with proteins and blood cells, live withinside the blood vessel. Under ordinary conditions, excessive molecular weight proteins withinside the plasma (e.g., albumin and globulin) can't skip via the filtration membrane because of the results of the scale barrier and rate barrier of the glomerular capillary filtration membrane.

What component allows semen to temporarily coagulate, preventing it from leaking back out of the female reproductive tract, once ejaculated

Answers

The protein-based compound called semenogelin is the main component that allows semen to temporarily coagulate and remain in the female reproductive tract after ejaculation.

This compound is produced primarily in the seminal vesicles, which are located in the male reproductive system. Semenogelin is composed of two major proteins, semenogelin I and semenogelin II. These two proteins combine to create a gel-like substance that helps semen to form a cohesive mass.

This mass helps to keep semen from leaking back out of the reproductive tract and helps to ensure that sperm are able to reach the egg for fertilization. The gel-like substance also helps to protect the sperm from the acidic environment of the female reproductive system. This coagulation process typically lasts for around 30 minutes before the semen begins to break down and is reabsorbed into the female reproductive tract.
