Answer:
ATP-Pcr System also known as an immediate energy system. The ATP- PCr system is the key energy source for a high-intensity, short-lived exercise of up to 10 seconds, such as swinginging a golf club, weight lifting, throwing a hammer, and pushing.
Glycolysis is the breakdown of glucose (C6H12O6 ) into pyruvate (CH3COCOO−) and H+ and releases free energy in order to to form ATP and NADH molecules.
ATP (adenosine triphosphate) is the stored source of energy readily available to the body when it interacts with water to generate heat and energy.
ATP is the body's primary energy source which hydrolyzed to releases lot of energy which results in protein synthesis and muscle contraction.
Hence, ATP is stored in body utilised during atp-pcr and glycolysis systems.

16. During electron transport reactions a. OH- accumulates on the outside of the membrane while H accumulates on the inside. b. OH- accumulates on the inside of the membrane while H accumulates on the outside. c. both OH- and H accumulate on the inside of the membrane. d. both OH- and H accumulate on the outside of the membrane
Answer:
Option B, OH- accumulates on the inside of the membrane while H+ accumulates on the outside.
Explanation:
In electron chain reaction, the electrons move through a series of electron transporters thereby undergoing redox reactions. This leads to accumulation of hydrogen ion (H+) with in the matrix and hence development of concentration gradient that leads to diffusion of hydrogen ion out of the matrix and accumulation of OH- ion on the inner side of the matrix while passing through ATP synthase
Hence, option B is correct
Final answer:
During electron transport reactions, hydrogen ions (H+) accumulate on one side of the membrane, creating an electrochemical gradient that can be used to synthesize ATP.
Explanation:
In the electron transport chain, a concentration gradient of hydrogen ions (H+) is established across the mitochondrial membrane. This creates an electrochemical gradient, with H+ ions accumulating on one side of the membrane. The electrons flow through a series of membrane-bound carriers, ultimately being accepted by oxygen to form water, while the H+ ions are pumped across the membrane.
The buildup of H+ ions on one side of the membrane creates a proton gradient that can be utilized to synthesize ATP from ADP and inorganic phosphate (Pi) through the action of ATP synthase.
Approximately how long has the victim been dead if his body temperature was 78.6°F?
Based on the victim's body temperature of 78.6°F, the estimated time of death is approximately 13 hours and 24 minutes.
Explanation:In order to determine how long a person has been dead based on their body temperature, we need to consider the concept of post-mortem cooling or algor mortis. The rate at which a body cools after death depends on various factors such as ambient temperature, clothing, and body composition. On average, a body cools at a rate of about 1.5°F (0.83°C) per hour in the first 12 hours, and then slows down.
If the victim's body temperature is 78.6°F, we can calculate an estimate by subtracting the body temperature from the normal average body temperature of 98.6°F. The difference is 20°F or 11.1°C. If we divide this difference by the rate of cooling (0.83°C per hour), we can estimate that the victim has been dead for approximately 13.39 hours or 13 hours and 24 minutes.
To estimate the time of death based on body temperature of 78.6°F, you can use the concept of postmortem cooling, where the body loses about 1.5°F per hour after death. By calculating the difference from the normal body temperature of 98.6°F and dividing it by the cooling rate, you can get a rough estimate. A difference of 20°F suggests approximately 13.3 hours since death.
Determining the time of death based solely on body temperature can be challenging, as various factors like ambient temperature, clothing, and individual characteristics play a role. However, a general guideline is that the body loses about 1.5°F per hour after death, known as postmortem cooling or algor mortis. If the victim's body temperature is 78.6°F, you could estimate the time of death by calculating how many degrees below the normal body temperature of 98.6°F the body is and then dividing by the average hourly cooling rate.
For example, if the difference is 20°F (98.6°F - 78.6°F), and the average cooling rate is 1.5°F per hour, you could estimate around 13.3 hours since death (20°F / 1.5°F per hour ≈ 13.3 hours). This is a simplified calculation, and actual conditions may vary.
The DSM-5 states criteria for the diagnosis of premature ejaculation by specifying that a man must ejaculate within _____ of beginning sexual activity and before the man wishes it on _____ of occasions over a period of at least _____.
Answer:
1 minute
75-100%
6 months
Explanation:
Premature ejaculation is the release of semen from the male reproductive organ at the very early stage of sexual activity usually between 30 seconds to one minute. Studies have shown that, it is rampant among first timers (those experiencing sexual activity for the first time) , in some which may persist for a while or over an extended period of time. However , a lot of remedies has been put in place to combat premature ejaculation such as ;usage of aphrodisiacs, or drugs from pharmaceutical stores.
Premature ejaculation which is the inability to full control over reflexes coordinating ejaculatory roles are sometimes caused by hormonal imbalance or psychological factors such as stress, over anxiety etc.
Answer:
The DSM-5 states criteria for the diagnosis of premature ejaculation by specifying that a man must ejaculate within __1 minute__ of beginning sexual activity and before the man wishes it on ___75%__ of occasions over a period of at least __6 months___.
Explanation:
The DSM-5 states that a person has premature or rapid ejaculation when he ejaculates after one minute has passed from the penetration, and the man does not want to ejaculate yet on the 75% or 100% of the time in 6 months or longer. An occasional premature ejaculation is normal, but if it happens regularly, a professional can help.
Which organelle captures the energy from sunlight and converts it to chemical energy
Answer:
the chloroplast
Explanation:
The chloroplast is an organelle usually found in plant cells and also in eukaryotic algae that aids in capturing energy from sunlight and converting it to chemical energy.

"What does the competition coefficient in the Lotka-Volterra competition model describe"? A. The difference in the carrying capacities of two species B. The effect of adding one individual of a species on the population growth rate of another species C. The number of individuals needed to drive another species to extinction D. The area of zero population growth
Answer:
The competition coefficient in the Lotka-Volterra competition model describes B. The effect of adding one individual of a species on the population growth rate of another species
Explanation:
The competition coefficient in the Lotka-Volterra competition model explains species competing for some common resource. It explains the effect of adding one individual of a species on the population growth rate of another species. They will compete for food with the colonies located near to them. When using equations for predation, the base population model is exponential.
Answer:
D. The area of zero population growth
Explanation:
Competition coefficient can be explained as the degree to which an individual of one species affects through competition. It can also be described as the growth or equilibrium level of a second species' population, relative to the effect of an individual of the second species.
The Lotka-Volterra model predicts that there could be a possibility of a stable coexistence of two species, only when intraspecific competition has a greater effect than interspecific competition.
In conclusion, the competition coefficient in the Lotka-Volterra competition model resulted in zero isocline, which shows one species having a growth rate (dN/dt) of zero.
From cells to major organ systems, the architecture of the body and the functions the body can perform are very closely related. Can you identify body cells, tissues, organs, systems that demonstrate this relationship and discuss its significance?
Answer:
Answer below.
Explanation:
In the respiratory system, cells of the lungs or alveoli are made up of simple squamous epithelium and have a lot of mitochondria present in them. This helps in the function of exchange of gases and the transport of these gases to and from the body thereby fulfilling the role of the respiratory system.
The skeletal muscle cells are made up of numerous mitochondria and are spindle-shaped. The fibres form the tissues of the muscles. The mitochondria helps in the skeletal muscle's role in motion as it makes sure energy is released for this activity. The skeletal muscle fibres are arranged in such a way as to facilitate their contraction and relaxation during movement.
The cells of the small intestine are made up of Golgi apparatus and vesicles and also organelles which facilitate the absorption of food nutrients from the intestinal passage.
The genetic code was originally deciphered, in part, by experiments in which synthetic polynucleotides with repeating sequences were used as mRNAs to direct protein synthesis in cell-free extracts. Under these conditions, ribosomes could be made to start translation anywhere within the RNA molecules, with no start codon necessary. What peptide would be made by translation from a synthetic mRNA made of the repeating dinucleotide CGCG…?
A. a polymer of arginine plus a polymer of alanine
B. the peptide Met–Arg–Ala–Arg–Ala…
C. a polymer of alanine: Ala–Ala–Ala…
D. a peptide containing alternating arginines and alanines
E. a polymer of arginine: Arg–Arg–Arg…
Answer: a peptide containing alternating arginines and alanines.
Explanation:
As the mRNA has a repeating unit of CGCG.
Now if we extend the units with more CG (CGCGCGCGCGCG) the pairing will be as CGC-GCG-CGC-GCG. and if we see the amino acids coded by these codons are arginine for CGC and alanine for GCG.
As this synthetic mRNA doesn't require any initiation codon (AUG) thus the polypeptide will not have methionine, which is the first amino acid in every polypeptide coded by the initiation codon.
Thus, the synthetic mRNA will code for peptide having alternating arginines and alanines amino acids.
what happens when a ecosystem is in equilibrium.
All living things must remain in balance, or equilibrium, also known as homeostasis. Our bodies maintain a balance of many things such as temperature. If we are too hot we sweat and if we are too cold we shiver. Our temperature must remain in equilibrium.
Even larger collections of living things like ecosystems must be in balance too. An ecosystem is a collection of living and non-living things in an area. There are lots of types of ecosystems we already know, such as a forest or a meadow. Any collection of living and non-living things in an area is an ecosystem, even a small ecosystem like your backyard.
Resources are plenty and predator and prey relationships are healthy. No competition for resources.
Answer:
the ecosystem is "Balanced"
Explanation:
Natural ecosystems are often incredibly sensitive to change, such as the introduction or removal of a species. A healthy ecosystem is said to be in equilibrium, which is a relatively stable state that keeps population sizes within a sustainable range (not too many of a certain species alive or dead). Consider the case of bears (who only eat fish) and salmon (who are only hunted by bears):

2. All objects emit radiant energy.
3. It can travel through empty space.
4. Radiation always causes illness.
5. It is the movement of heat by electromagnetic waves.
Answer:
3 it can travel through empty space
The incorrect statement about radiation is that it always causes illness. Radiation, which is the transfer of energy through electromagnetic waves, is not inherently harmful and is vital for many natural processes.
The statement that is NOT true about all forms of radiation is: Radiation always causes illness. This is a misconception, as radiation refers to the transfer of energy through electromagnetic waves, which can occur naturally and are not always harmful. Objects at temperatures above absolute zero emit radiant energy, and this energy transfer does not require a medium; it can travel through empty space. Radiation is vital for various natural processes, such as photosynthesis in plants. While certain types of radiation at high levels can cause harm and lead to illness, not all radiation is harmful and many types are essential for life.

The barn above looks red because certain rays of light are absorbed by the barn and other rays of light are reflected by the barn. What must be true about the original sunlight before it hits the barn?
Answer:
The original sunlight is a mixture of colors.
Explanation:
The sunlight is perceived by our eyes as white because it is a mixture of seven colors - violet, indigo, blue, green, yellow, orange, and red. When these colors of light separate from each other and are differentially absorbed and reflected, we can see the different objects in different colors. The reason for the differential absorption and reflection is that the different colors have different wavelengths. Therefore, the barn looks red because the red light is reflected by the barn and other lights are absorbed, however, the original color of the sunlight is white.Answer: the answer is “ The original sunlight is a mixture of colors“ :)

Scientists have successfully cloned sheep and cattle for several years. A farmer is considering the advantages and disadvantages of having a flock of sheep cloned from a single individual. Discuss the issues the farmer should take into account before making a decision.
Answer:
Cloning is the mechanism by which one living organism takes genetic material and produces identical copies of it. Cells, organs, chromosomes and whole species have been cloned by geneticists.
The scientist need to take of some of the issues before cloning of sheep are as following:
Conflict with long-standing religious and social values about human dignity, probably infringing the principles of equality, identity and autonomy of each person.Cloned embryos face the same difficulties as naturally occurring pregnancies, plus others that are unique to cloning, so embryonic condition should be maintained. Cloned embryos surviving pregnancy may be born with a number of birth defects and other health issues. However, cloned cells can lack the programming required to tell the genes when to turn on and off. The outcome could be disorganised cell growth or abnormal functioning of the cell, all of which may lead to death of an organism.Final answer:
A farmer considering cloning a flock of sheep should take into account the low success rates, potential health complications as observed in Dolly and other clones, and the bioethical considerations surrounding the cloning process.
Explanation:
When considering the cloning of a flock of sheep from a single individual, several key issues arise. The case of Dolly the sheep, the first cloned agricultural animal, provides insights into potential challenges. Reproductive cloning had a very low success rate at the time, and Dolly herself lived for seven years before dying of respiratory complications. There is a concern that the age of the donor DNA might affect the lifespan of the clones, as observed with Dolly, whose DNA came from an older individual. Also, since that time, cloned animals have been reported to exhibit various abnormalities, including those affecting the face, limbs, and heart.
There are also potential benefits of cloning, such as creating animals that overproduce certain proteins for medical purposes, and even possibly bringing back extinct species. However, alongside the practical considerations, there are also bioethical considerations to weigh, as the debate over cloning's morality, especially concerning therapeutic uses, is still ongoing. A farmer contemplating cloning must weigh these potential health risks and ethical debates against cloning's potential benefits.

You are studying leaf development in a member of the mustard family. You identify several mutants of interest in this plant and make pure (true-breeding) lines of each mutant for further study. You decide to conduct a genetic analysis of these mutant lines by crossing each with a pure wild-type line. The numbers in the F2 indicate the number of progeny in each phenotypic class. Three crosses between pure lines of flowers. The first cross is between twist and wild type flowers. F1 flowers have twisted leaves. When F1 flowers were crossed with each other, 53 twisted and 18 wild type flowers were obtained. The second cross is between forked and wild type flowers. The F1 generation is all forked, and when they are crossed with each other, 49 forked and 16 wild type flowers were obtained. The third cross is between pale and wild type flowers. The F1 generation was of middle coloring and when they were crossed with each other, 17 wild type, 16 pale, and 34 middle type flowers were obtained. From these results, determine the relationship between the mutant allele and its corresponding wild-type allele in each line.
Answer:
•The relationship between the twist and the wild type flower in the first crossing is known as a COMPLETE DOMINANCE
•The relationship between the forked and the wild type flower in the second crossing is also known as a COMPLETE DOMINANCE
•The relationship between the pale and the wild type flower in the third crossing is known as an INCOMPLETE DOMINANCE
Explanation:
A complete dominance is characterised by having one of the genes (the dominant gene) in an heterozygous condition, completely masking the effect of the other (the recessive gene) of thesame allelic pair. E.g. if the genes in allelic is represented with Aa, "A" is said to completely dominate "a" if it does not allow "a" to Express itself phenotypically.
The heterozygous condition is always the result of the F1 generation
and the F2 generation of a Complete dominance is always characterised by a phenotypic ratio of 3:1 which is in line with the results gotten from the first crossing and the second crossing as stated in the question.
An complete dominance is characterised by having an intermediate progeny in the F1 generation which was evident in the result of the third crossing. Also a phenotypic ratio of 1:2:1 in the F2 generation is also a characteristic feature of an Incomplete dominance relationship which was also evident in the third crossing.
The twisted and forked traits are dominant to the wild-type, as shown by their 3:1 phenotypic ratios in the F2 generation. For the pale trait, the 1:2:1 F2 generation phenotypic ratio suggests incomplete dominance with an intermediate phenotype in heterozygotes.
To determine the relationship between the mutant allele and its corresponding wild-type allele in each line, we can refer to Mendel's laws of inheritance, specifically considering the phenotypic ratios in the F2 generation. The first and second crosses showed a phenotypic ratio close to 3:1, indicating that the twisted and forked traits are likely dominant over their corresponding wild-type phenotypes. Thus, the mutant allele for twist and forked would be dominant to the wild-type allele.
For the third cross involving pale and wild-type flowers, the phenotypic ratio is 1:2:1 in the F2 generation, with wild type, pale, and middle type flowers. This suggests incomplete dominance, where the heterozygous condition results in an intermediate phenotype (middle type). Therefore, for the pale mutant, the relationship with the wild-type allele is one of incomplete dominance.

Answer:
The cascade amplifies the cellular signal, thereby receptor activation lead to potent responses
Explanation:
Usual signal transduction is produced by protein phosphorylation, this posttranslational modification activates signal transductors in order to bind receptors and ligands. In multicellular organisms, the signal transduction pathways regulate critical cellular processes including, for example, cell communication
What are the fixed alleles in the human species?
O
A. The alleles that everyone has
O
B. The alleles that change most often
O
C. The alleles that are on the most chromosomes
O
D. The alleles that no one has
Fixed alleles are those that are the only variant that exists for a gene within a species, meaning every individual in the population has this allele. An example of unfixed alleles is the A, B, and O alleles of the ABO blood type system, which are not fixed because they occur in varying combinations in the population.
The correct answer to what fixed alleles are in the human species is A, the alleles that everyone has. Fixed alleles are those that are the only variant that exists for a gene within a species because all individuals are homozygous for that allele. An example of alleles that are not fixed in humans are the A, B, and O alleles of the ABO blood group system; these are common alleles present in the population that determine an individual's blood type. Alleles like A and B produce modifications on the surface proteins of red blood cells, while the O allele produces no modification.
In the case of the ABO blood system, the majority of human genes have two or more possible alleles or alternative forms of a gene that account for the genetic variation among people. However, a fixed allele would be one that is uniform among all individuals within a population, which means that no other allelic variants are present.
A child is born with sickle cell anemia. What can you conclude about the potential genotypes of the parents?
Answer:
The potential parental genotypes could be "both recessive" or "both heterozygous".
Explanation:
Sickle cell anemia is a disease where there are not enough red blood cells throughout the body so they are not able to carry the necessary amount of oxygen for the body to function properly. It is a disease that is carried on recessive genes so for an individual to have this disorder, they must have to recessive genes from both parents. In this case the potential parental genotypes could be "both recessive" or "both heterozygous".
