In the above study, the investigators determined that a low concentration of DNP increased the average life span from 719 days (Control) to 770 days (DNP). If the U.S. population has an average life span of 79 years, then how many years would be added if the same percentage increase were observed?
Express your answer using two significant figures.
Answer:
Increase in average life span of U.S. in terms of years is [tex]5.6\\[/tex] years
Explanation:
The controlled average life span is [tex]719\\[/tex] days
The DNP average life span is [tex]770\\[/tex] days
Increase in the average life span is
[tex]770 - 719\\= 51\\[/tex] days
Rate of increase of average life span after using DNP
(Change in life span in day [tex]/\\[/tex] Base average life span) [tex]* 100\\[/tex]
[tex]= \frac{51}{719} * 100\\= 7.09\\[/tex] %
It is given that the average life span of US people will also increase by the same rate, then the new average life span would be
Base average life span [tex]+\\[/tex] Increase in average life span
[tex]= 79 + ((\frac{7.09}{100} ) * 79)\\= 84.60\\[/tex]
So the increase in average life span of U.S. in terms of years is [tex]5.6\\[/tex] years

During glacial periods, the concentration of carbon dioxide in trapped air bubbles in glacial ice is ___ when compared to the concentration during interglacial periods. lower much higher higher the same
During glacial periods, the concentration of carbon dioxide in trapped air bubbles in glacial ice is lower compared to interglacial periods. Ice core data shows a range of about 180 ppm during glacial maxima to 280 ppm during interglacials.
During glacial periods, the concentration of carbon dioxide (CO2) in trapped air bubbles in glacial ice is lower when compared to the concentration during interglacial periods. This is evidenced by ice core data which shows that CO2 concentrations varied between about 180 parts per million (ppm) during glacial maxima and 280 ppm during interglacials. The lower levels of CO2 during glacial periods are linked to cooler global temperatures and are a result of various biological and geochemical processes.
During the last Ice Age, for example, CO2 levels were below 200 ppm and average temperatures were significantly colder than today. Studies, such as those involving foraminifera and ice core records, have demonstrated a tight connection between climate and the carbon cycle, indicating that changes in atmospheric CO2 concentrations can influence global climate patterns, as well as be affected by them.
According to the Doppler effect, the sound of a police car siren is and pitched as it approaches the observer.
Answer:
On the basis of the Doppler effect, the sound of a police car siren is louder and higher pitched as it move towards the observer.
Explanation:
Whenever the police car with a siren moves towards an individual, the frequency of the siren will increase and the reverse happens when the police car moves away from the person. The individual can listen to the sound of the siren louder and clearer when the car approaches the individual, as the sound is highly pitched when it moves towards the observer. This phenomenon is known as the Doppler effect.
Most connective tissue, including bone, is highly vascular. which anatomical structures in mrs. morgan's compact bone house blood vessels? what sign or symptom in mrs. morgan's case is directly related to disruption of these structures by her bone fractures? how is the sign or symptom related to these anatomical structures?
The blood vessels are both housed by the Haversian canal and the Bolkmann’s canal.
The given info that she is bleeding so abundantly only means that she has a hemorrhage. Hemorrhage is the loss of blood due to rupture walls in the blood vessels.
This sign is related to these structures since one of the canals was actually ruptured when her bone was fractured and then forced out of the skin.
What will change if you permanently increase the extracellular K+ concentration? (more than one answer is possible)
a. the amplitude of action potential
b. the resting membrane potential
c. the membrane capacitance
d. the permeability of the neuron cell
e. the k+ conductance
The correct answer is option (a.) the amplitude of action potential, (b.) the resting membrane potential and (e.) the K+ conductance.
Increasing the extracellular K+ concentration will depolarize the cell, leading to a less negative resting membrane potential. This change will decrease the resting membrane potential closer to the equilibrium potential for K+. Consequently, it will also decrease the electrochemical gradient for K+ ions and reduce the driving force for K+ efflux. As a result, the K+ conductance will decrease. Finally, the amplitude of the action potential may decrease because the smaller electrochemical gradient for K+ ions will lead to a smaller K+ efflux during repolarization.
The incorrect options are:
c. The membrane capacitance: The membrane capacitance refers to the ability of the cell membrane to store charge. Increasing the extracellular K+ concentration does not directly affect membrane capacitance. Instead, it primarily affects the electrical properties of the membrane through changes in ion concentrations and permeability.
d. The permeability of the neuron cell: Increasing extracellular K+ concentration primarily affects the resting membrane potential and the electrical properties of the cell membrane, but it doesn't directly alter the permeability of the neuron cell. Permeability changes typically occur due to alterations in ion channels or membrane properties, not solely due to changes in extracellular ion concentrations.

Marla is a healthy 30-year-old woman. she doesn't work out, but she consumes protein supplements because she thinks they will increase her muscle mass without the need to exercise. based on this information, the excess amino acids in her diet will
Answering the question, based on this information, the excess amino acid in her diet will be mostly converted into carbon skeletons and ammonia.
When a person takes excesses of protein supplements, the excess amino acids in the small intestines after protein digestion are moved to the liver. One of the metabolic functions of the liver is to remove excess amino acid in the body, which is discharged as waste because the human body cannot store amino acids or proteins.
Further ExplanationAlso, there are types of chemical reactions that take place when excess amino acids are transported into the liver, the product of this reaction forms ammonia, which is very toxic and should not build up in the body. Therefore, the excess ammonia is converted to urea, the urea then forms and moves into the bloodstream which is filtered by the kidney and excreted in the urine
Proper exercise after consuming protein supplements is very essential. Mary’s actions can result in various health problems such as blood vessel disorder, seizures, liver injuries, and even death.
Therefore, Marla should have a work out after consuming protein supplements otherwise the excess amino acid in her diet will be mostly converted into carbon skeletons and ammonia.

marlaproteinsamino acidammoniamuscleA healthy 30-year-old woman consuming excess protein supplements without exercise will likely see the excess amino acids 1) Undergo deamination in her liver, potentially be stored as fat, and will not specifically enhance muscle mass or calcium absorption without the stimulus of exercise.
Given that Marla is a healthy 30-year-old woman who does not work out but consumes protein supplements, the excess amino acids from her protein-rich diet will likely undergo several metabolic processes. Undergo deamination in her liver is one likely outcome. During this process, the amino acids are stripped of their nitrogen-containing amino groups, which are then converted into ammonia and further processed into urea for excretion in the urine. If Marla's diet is especially excessive in protein, it could lead to her body converting and storing the excess as fat rather than adding it to her muscle tissue without exercise to stimulate muscle growth.
It is important to note that consuming high levels of amino acid supplements without corresponding exercise may not lead to an increase in muscle mass and can disrupt the balance of amino acid absorption due to competition for transport systems. As such, the excess amino acids will not be added to her muscle tissue (option 2) without exercise, nor specifically enhance her body's absorption of calcium (option 4). If energy needs are met, they are also not likely to be metabolized for energy quickly (option 3).
Consider how lettuce or spinach placed in water becomes firm and crisp. Use what you have learned about cell membranes to explain this observation
Lettuce or spinach when placed in water becomes firm and crisp by the process of osmosis.
The diffusion of solvent molecules through a selectively permeable membrane from a location of high water potential to a region of low water potential in the direction that tends to equalize the concentration of solutes on the two sides is referred to as osmosis.
Endosmosis and exosmosis are the two different types of osmosis.
Endosmosis-if a substance is placed in a hypotonic solution, the solvent molecules move inside the cell and the cell becomes firm or rigid.Exosmosis- if a substance is placed in a hypertonic solution, the solvent molecules move out of the cell.The cell membrane of lettuce or spinach is semipermeable, so when they are placed in water, the water moves inside the lettuce by the process of endosmosis, and the lettuce or spinach becomes firm and crisp.

A fragment of dna was found to have 45 adenine bases and 25 guanine bases. what is the total number of deoxyribose molecules in the molecule?
The DNA fragment has 45 adenine bases and 25 guanine bases, making a total of 70 bases. Therefore, as each deoxyribonucleotide contains one deoxyribose sugar, the total number of deoxyribose would be 70.
Explanation:The structure of a DNA molecule is based on nucleotides, each containing a five-carbon sugar called deoxyribose, a phosphate group, and a nitrogenous base. These nitrogenous bases can be adenine (A), guanine (G), cytosine (C), or thymine (T). As the question specifies, the fragment of DNA has 45 adenine bases and 25 guanine bases. Therefore, we can conclude there are 70 deoxyribonucleotides that form part of the DNA strand.
Since each deoxyribonucleotide contains one deoxyribose sugar, the total number of deoxyribose molecules present in the fragment would be equal to the total number of bases i.e. adenine bases + guanine bases, which is 45+25 = 70.
So the total number of deoxyribose molecules in this fragment of DNA would be 70.

Imagine your forearm, hand, and fingers as a giant model of a neuron. based on this model, fingers are to dendrites as _____ is to _____. forearm; cell body hand; axon hand; cell body forearm; myelin
Answer:
Imagine your forearm, hand, and fingers as a giant model of a neuron. based on this model, fingers are to dendrites as hand is to cell body.
Explanation:
Neurons have three basic parts: the dendrites, the axon and the cell body. If we use the forearm, hand and fingers to represent this structure, we can say that the fingers would be the dendrites, the hand is the body of the cell and the forearm the axon.
Dendrites are extensions of the neuron that guarantee the reception of stimuli, leading the nerve impulse towards the cell body. The vast majority of neurons have a large amount of dendrites.
The axon is the extension that ensures the conduction of the nerve impulse. Each neuron has only one axon, which is generally longer than the dendrites.
The cell body is the site of the neuron where the nucleus is present, most of the cell organelles, and where the extensions of that cell depart.

In animals, the bulk of energy is stored as __________.
a. fatty acids
b. triacylglycerols
c. glycogen
d. waxes
e. glycerophospholipids
Final answer:
The bulk of energy in animals is stored as triacylglycerols or triglycerides, which are made of glycerol and three fatty acids, and provide long-term energy storage.
Explanation:
In animals, the bulk of energy is stored as triacylglycerols, also known as triglycerides. These molecules are the primary form of long-term energy storage in animals and consist of one glycerol molecule esterified to three fatty acids. After being made, triglycerides are stored in specialized cells called adipocytes. When energy is needed, enzymes called lipases hydrolyze the triglycerides, releasing fatty acids that can be catabolized through a process called beta-oxidation. This occurs in the mitochondria, generating two-carbon acetyl units which enter the citric acid cycle as acetyl CoA, to be ultimately used for ATP production. Glycerol, on the other hand, can be phosphorylated and enter glycolysis to further contribute to cellular energy supply.
