In a sample of DNA, thymine will make up 10% of the total.

DNA structure:

According to Chargaff, nucleotide subunits make up the DNA. The double-stranded DNA molecule is created by these nucleotides forming hydrogen bonds with one another.

The following nucleotides can be found in the DNA molecule:

While Guanine (G) couples with Cytosine (C), Adenine (A) pairs with Thymine (T).

According to Chargaff's rule, the ratio of adenine to thymine in a DNA molecule is equal. The same holds true for cytosine and guanine. The entire number of nucleotides, however, is 1, or 100%.

A + T + G + C = 100%.

if cytosine makes up 40% of the DNA sample, this means that guanine will also be 40%.

G (40) + C (40) = 80%

100% - 80% =20%

This means that Adenine and Thymine amounts to 20%. The amount of each nucleotide will be 20% ÷ 2 = 10% i.e. A = T = 10%

Therefore, the percentage of thymine in a sample of the DNA will be 10%.

An individual develops anemia (low red blood cell counts). During moderate exercise, lactic acid accumulates in her muscles. This is primarily a consequence of a reduction in oxygen levels in the muscles.

Lactic acid accumulates in the muscles of an individual who has developed anemia during moderate exercise primarily as a result of a reduction in oxygen levels in the muscles. Anemia is a medical condition in which the body lacks sufficient red blood cells or hemoglobin.

It occurs when the body is not producing enough red blood cells, the existing red blood cells are not functioning properly, or the red blood cells are being destroyed too quickly. As a result, less oxygen is supplied to the muscles during exercise and lactic acid accumulates, causing fatigue and pain.Lactic acid accumulation is caused by the production of energy in the body's cells when the oxygen levels in the muscle tissues drop.

This happens when the body can't supply enough oxygen to the muscles, which occurs during moderate exercise in individuals with anemia. The accumulation of lactic acid in the muscle tissue, which results in fatigue, cramps, and other symptoms, is caused by the buildup of lactate.

Answer: Commensalism

Explanation:

Commensalism is a type of feeding relationship between organisms of two (2) species, it is characterised by one organism gaining food and benefiting from another organisms without causing harm to the organism.

In Commensalism, one organism benefits and the other doesn't get any benefit nor get hurt.

Commensalism is the feeding relationship between triggerfish and other fishes.

Triggerfish are carnivorous,hence they eat mainly urchins,worms, crabs, shrimps and several types of invertebrates,they also feed on animals that attach themselves to corals and this gives an impression of them feeding from the corals whereas no harm is being done hence the Commensalism

Answer:

Commensalism

Explanation:

Commensalism is a type of feeding relationship that exists between two different organisms where neither organism gains nor loses.

The triggerfish feeds on organisms found under corals which includes shrimps and other smaller organisms etc found in these coral reefs environment.

Its absence has been discovered to have an influence on the population of other species of fish in that environment. They are not harmed neither do they benefit from the other population of fish. Thus the relationship is tagged commensalism.

Measles is transmitted through direct contact with respiratory secretions or airborne droplets from an infected person, typically through coughing or sneezing.

Measles is primarily transmitted through airborne respiratory droplets.

Measles, also known as rubeola, is a highly contagious viral infection. It spreads easily from person to person through respiratory droplets when an infected individual coughs, sneezes, or talks.

The virus can survive in the air or on surfaces for a few hours, making it highly transmissible.

Measles is one of the most contagious diseases known to humans, with an estimated 90% of susceptible individuals who come into contact with an infected person contracting the virus.

Once the virus enters the body through the respiratory system, it replicates in the throat and lungs.

It then spreads throughout the body via the bloodstream, causing the characteristic symptoms of measles, including fever, cough, runny nose, rash, and systemic illness.

Vaccination is the most effective way to prevent measles transmission.

The measles vaccine, usually administered as the measles-mumps-rubella (MMR) vaccine, provides immunity against the virus and helps protect individuals from infection.

Maintaining high vaccination coverage in communities is crucial to prevent outbreaks and reduce the spread of measles.

In conclusion, measles is transmitted through airborne respiratory droplets when an infected individual coughs, sneezes, or talks.

It is essential to follow proper infection control measures, including vaccination, to prevent the transmission and spread of measles.

Codons are units of genomic information made up of three nucleotides (trinucleotides) in DNA or RNA that code for a specific amino acid or indicate the end of protein synthesis (stop signals).

An amino acid is encoded by a codon, a triplet of nucleotides. An amino acid is encoded by each trio of nucleotides. A, U, G, and C are the four nucleotides found in mRNA, and together they can be combined in 64 distinct ways because codons are three-letter structures. The remaining three of these 64 codons are stop signals that signal the completion of protein synthesis, and 61 of these codons correspond to amino acids. UAG, UAA, and UGA are the three STOP codons found in the genetic code.

The range of frequencies that humans can hear relatively soft (low energy) sounds is typically between 20 Hz to 20,000 Hz. This range is commonly known as the audible frequency range. However, it's important to note that the ability to hear sounds within this range varies from person to person, and can also be influenced by age, gender, and other factors.

At the lower end of the audible frequency range, sounds with frequencies below 20 Hz are known as infrasound, and are often felt more than heard. On the other end, sounds with frequencies above 20,000 Hz are known as ultrasound, and are also beyond the range of human hearing.

The ability to hear different frequencies within the audible range is due to the complex mechanisms of the human ear. Sound waves are captured by the outer ear, which then travel through the ear canal and vibrate the eardrum.

This vibration is transmitted through a series of tiny bones in the middle ear and ultimately reaches the cochlea in the inner ear. Here, specialized hair cells are stimulated by different frequencies of sound, which send electrical signals to the brain for processing.

Overall, the range of frequencies that humans can hear relatively soft sounds is a crucial aspect of our ability to perceive and communicate through sound.

Archosaurs are a group of organisms that belong to the same clade that is Dinosauria.

There is abundant evidence that birds developed within the clade Dinosauria, which is broken down into two groups, dinosaur hips (Saurischia) and bird hips (Ornithischia). Despite the names, it wasn’t bird-hipping dinosaurs that created modern birds. Instead, Saurischia split into two groups: one that included long-necked, herbivorous dinosaurs like Apatosaurus, and the second group that gave rise to birds as bipedal predators known as theropods.

There are many similarities between late (maniraptoran) dinosaur fossils and birds, particularly in the structure of hip and wrist bones and the presence of a wishbone formed by the fusion of clavicles.

The correct amino acid can be incorporated into the protein despite a in the gene sequence through a process called codon redundancy or degeneracy.

The multiple codons (a sequence of three nucleotides) can code for the same amino acid. For example, the amino acid leucine can be coded for by the codons UUA, UUG, CUU, CUC, CUA, and CUG.

Therefore, if a mutation occurs in one of the nucleotides in the codon, it may still code for the same amino acid and the protein will be unaffected.

However, if the mutation causes a change in the amino acid, it can potentially alter the structure and function of the protein.

The given statement "Killed and attenuated influenza vaccines typically contain three types of viruses" is True. Influenza vaccines, also known as flu shots, are designed to protect against infection by the influenza virus.

There are two main types of vaccines: inactivated (killed) and live attenuated (weakened) vaccines. The inactivated or killed vaccines contain virus particles that have been grown in the lab and then chemically inactivated, meaning they can no longer cause an infection. Live attenuated vaccines contain a weakened form of the live virus that can still replicate, but it is much less likely to cause illness in healthy individuals.

Both types of vaccines usually include three types of influenza viruses: two strains of influenza A (H1N1 and H3N2) and one strain of influenza B. These three strains are chosen based on the World Health Organization's (WHO) recommendations, which are made each year based on global surveillance of circulating influenza viruses. This is done to provide the broadest protection possible, as the flu virus is constantly changing and evolving.

Including these three types of viruses in the vaccine aims to provide protection against the most prevalent strains of the flu for that specific flu season. However, it's important to note that the effectiveness of the vaccine can vary from year to year, depending on how well the vaccine strains match the circulating viruses.

In summary, it is true that killed and attenuated influenza vaccines typically contain three types of viruses to provide protection against the most common strains of the flu.
