Using the diagram below, identify the ONLY portion of the nucleotide that is not the same in every piece of DNA. (phosphate, sugar, or base)

Answers

Answer:

Base

Explanation:

Deoxyribonucleic acid, DNA, is one of the four major biomolecules in living organisms. It is a polymer made up of monomers called NUCLEOTIDES. The nucleotides that make up a DNA molecule is composed of three substances namely: Sugar (deoxyribose), nitrogenous base, and a phosphate group.

However, among these three components of the nucleotide monomer, NITROGENOUS BASE is the only portion that is not the same in every DNA molecule. There are four nitrogenous bases in nature viz: Adenine, Guanine, Cytosine and Thymine. These four bases can be alternated in a DNA molecule.

Note that, phosphate group and deoxyribose sugar are constant in every DNA.

Answers

Answer:

A mutation is the changing of the structure of a gene, resulting in a variant form that may be transmitted to subsequent generations, caused by the alteration of single base units in DNA, or the deletion, insertion, or rearrangement of larger sections of genes or chromosomes. Mutations in sex cells are more serious because they are heritable and affect the next generation.

Having freckles is a dominant trait, and not having freckles is a recessive trait. Which set of parents will not have any children with freckles? A. A mother with FF and a father with ff O B. A mother with Ffand a father with Ff O c. A mother with ff and a father with ff​

Answers

As freckles are a dominant trait, they will not occur in the children with a homozygous recessive trait, i.e., ff. The correct option is C.

What are recessive traits?

Recessive trait is a  trait that really should be transmitted by both parents in order to be present in the offspring. Recessive features might exist in a person's DNA but not manifest in that individual.

As in the given case, F denotes dominance, and f denotes recessive character. Dominant trait always superimpose over the recessive one.

So, as freckles are a dominant trait, they will not occur in the children with a homozygous recessive trait i.e., ff.

Thus, the correct option is C.

138) Six-year-old Matthew broke his femur and one of his epiphyseal plates was damaged. Explain the role of the epiphyseal plate in longitudinal growth and predict the effects of a damaged epiphyseal plate on his future longitudinal growth.

Answers

Answer:

The function of the physis or growth plate is to allow the growth in length of the bones (both long as short) through the endochondral ossification process.

Explanation:

The epiphyseal plates are areas of active growth of new bone at the ends of the bones, made up of cartilage that hardens once the child is fully developed. Epiphyseal plates help determine the length and shape of the adult bone eventually. It is the last part of the bones to harden, and therefore they are vulnerable to fractures. The complication of the involvement of the growth plate is the deformity or lack of growth of the bone, leaving the limb twisted or shorter than the contralateral one.Growth disturbances are more frequent when the affected area is very large or when it involves the area of ​​the knee joint. In cases of shoulder or wrist involvement, deformities rarely occur. The alterations are more common when the lesions occur in younger children, because they have a longer growth period.

white eyes are recessive in flies. can two red eyed flies have white eyed offspring

Answers

Answer:

Considering that white eyes are a recessive trait in flies, it is possible for two red-eyed flies to have offspring with white eyes only if both are heterozygous for this trait.

Explanation:

For two individuals with dominant phenotype for a trait to have offspring with the recessive trait, both must have a heterozygous genotype.

In the case of the characteristic eye color of the flies :

Red eye (R) is dominant trait. White eyes (r) is the recessive trait.

When both parents are heterozygous, their genotype is Rr

In Punnett Square it can see the result of the crossing of these individuals:

Punnett Square :

Rr X Rr

Alleles     R     r

R              RR   Rr

r               Rr    rr

In the offspring, the probabilities are:

50% heterozygous individuals Rr, with red eye phenotype. 25% pure dominant individuals RR, with red eyes 25% individuals with the recessive rr genotype, white eyes.

This is the possibility of two red-eyed flies having white-eyed offspring.

which respiratory substrate has a respiratory quotient of 0.5​

Answers

How can it be used clinically?
The RQ is the ratio of the patient's carbon dioxide production (VCO2) to his or her oxygen consumption (VO2). These values are obtained by indirect calorimetry at the patient's bedside. The RQ is helpful in guiding the planning of nutritional therapy. The physiologic range for RQ values is 0.7 to 1.2 and is influenced by the relative contribution from fat, protein, and carbohydrate. RQ values for fat, protein, and carbohydrate are 0.7, 0.8, and 1.0, respectively. Thus, an RQ of >1.0 might suggest excessive carbohydrate or calorie provision that can result in increased CO2 production and cause difficulty weaning from mechanical ventilation. A RQ of <0.7 might suggest underfeeding and use of ketones as a fuel source. The use of energy fuels by animals and by a flame may be compared by considering the stoichiometry of the chemical reactions. They may also be compared by noting the amount of energy produced with complete oxidation of the fuel in question. The following discussion begins with the stoichiometry of combustion of simple compounds — such as paraffin, methane, and methanol — and then continues onto the combustion of more complex materials — such as glucose and fat. The study of the stoichiometry of various reactions requires the counting of the number of molecules of CO2 produced per molecule of fuel combusted, the number of water molecules produced, and the number of oxygen atoms (or molecules) consumed.
The stoichiometry involved in the combustion of fuels can be used to calculate a very interesting ratio: the number of CO2 molecules discharged from the body per number of oxygen molecules consumed. This ratio (CO2/O2) is called the respiratory quotient (RQ). The biochemical events of CO2 production and O2 utilization are a direct result of the oxidation of various fuels such as fat and glucose. The amount of O2 used is also influenced by the rate of synthesis of new fat in the body. Respiratory gases can be measured and analyzed quite easily. These measurements can be used to calculate the amount of CO2 produced and O2 used by the body over any given period. Calculating the RQ for a subject is quite easy and can provide remarkable insight into the overall behavior of energy fuels in the body. The RQ can provide only limited information on metabolism, but it is a powerful measurement.
The RQ is different for different fuels. For example, the RQ for the complete combustion of glucose is 1.0, and that for the complete combustion of fat is 0.7. These values are determined in three ways:
1.
On paper, by balancing chemical formulas, with no knowledge of metabolic pathways.
2.
By consideration of the biochemical pathways of the body, providing that these pathways have been memorized or are available in some format.
3.
Experimentally, by use of a furnace. The furnace contains an atmosphere of pure oxygen. A mechanism for igniting the fuel or food in question, as well as devices for measuring the amount of CO2 produced and O2 consumed, is available.
Knowledge of the RQ for different energy fuels can be used to determine the predominant fuel used by a particular organ of the body, such as the muscle or brain. To determine the RQ for a particular organ, the blood entering and exiting that organ must be analyzed. Most of the oxygen entering and exiting the organ is bound to hemoglobin. Most of the CO2 entering and exiting the organ is in the form of bicarbonate.

If a female fruit fly is heterozygous with the allele for white eyes being recessive and the red eyes being dominant on the X-chromosome. She is crossed with a hemizygous red eyed male, what would be the expected ratio of male and female phenotypes if they were bred together?

Answers

Answer:

100% red eyes because there is 50% AA and 50% Aa.

Explanation:

To find the expected ratio of male and female phenotypes if they were bred together, you need to make a punnett square/table.

Female: A a

"A" is white eyes, which is RARE. "a" is red eyes, which is COMMON.

Male: A A

"A" is red eyes, which is COMMON.

Multiply Aa x AA by a punnett square.

GUIDE:

1. AA is common and does not carry the recessive gene of being white-eyed. 2. aa is rare and carries the recessive gene of being white-eyed.

3. Aa is common as being red-eyed since being red-eyed is dominant, but carries the recessive gene of being white-eyed.

In your own words, explain why an organism would require all four of the main biomolecules. What would occur if any of these biomolecules were missing? Are any of the biomolecules more important than the others? Is there one that we could live without?

Answers

Answer:

An organism requires all four main biomolecules because each provides a specific and necessary function for the organism. None of the biomolecules is more important than another, and if any of them were missing, life would not be possible.

Explanation:

The main biomolecules of living beings are carbohydrates, proteins, lipids and nucleic acids, each with a specific function and necessary for the development of life.

The presence of these four biomolecules is necessary because each one fulfills specific and irreplaceable functions, such as:

Carbohydrates: are the main source of energy, forming part of organic biomolecules such as glycolipids, glycoproteins or sugars that form the structure of nucleic acids.Proteins: important for their structural function and for molecules such as enzymes, which contribute to organic functions. They are also part of the cell membranes.Lipids: are the molecules that predominantly form the cell membranes. Additionally, they form functional molecules, such as hormones, and are a reserve energy source.Nucleic acids: DNA and RNA are not only necessary for organic biosynthesis, but also determine the structure and function of each organism. The reproductive and perpetuation function of the species is based on the transfer of genetic material contained in the DNA to the offspring.What would occur if any of these biomolecules were missing?

If one of the main biomolecules were missing, the function it provides could not be supplied by another, which would imply the non-viability of a living being. If carbohydrates are missing there is no source of energy, without proteins there would be no tissues like muscle and no enzymes to facilitate organic reactions and without lipids there would be no cells. The absence of nucleic acids, per se, would determine the impossibility of all organic processes.

Are any of the biomolecules more important than the others?

No one biomolecule is more important than another. Each one of them fulfills a specific and necessary function that cannot be supplied by another biomolecule.

Is there one that we could live without?

All organic molecules are necessary, fulfilling an important function. The lack of any biomolecule in the organism is incompatible with life.

An organism requires all four of the main biomolecules because they're all important for the effective functioning of the organism.

It should be noted that the main biomolecules include protein, lipid, carbohydrates, and nucleic acids. They all play a vital role in how an organism functions.

If any of these biomolecules were missing, the function that can be provided by the biomolecule can't be provided by another biomolecule since they all play different roles. Also, there's no biomolecule that's important than another.
