Suggest why energy from the sun flows in one direction while materials are cycle within an ecosystem
Answer:
Energy flow in an ecosystem is unidirectional. It means that energy which is absorbed by the producers from sun and is converted into chemical energy, always flow from a lower trophic level to a higher trophic level as in a food chain when herbivore consumes producers the energy is transferred from producers to consumers and so on. Some of this energy is assimilated some is used by the organism and some is dessipated in the environment but the flow of energy is never reverted, that is obviously a producer can not consume a consumer.

During a large thunderstorm, you hear and feel the thunder. Draw a representation of the sound wave produced. Your model should account for the energy and patterns of the wave.
Answer:
Sound waves are longitudinal waves that travel through a medium like air or water. When we think about sound, we often think about how loud it is (amplitude, or intensity) and its pitch (frequency).
Explanation:
This is why we hear and feel them!
Sound waves are longitudinal waves that travel through a medium like air or water. When we think about sound, we often think about how loud it is (amplitude, or intensity) and its pitch (frequency).
What is Sound waves?A sound wave is the pattern of disruption brought on by the movement of energy moving through a medium as it propagates away from the source of the sound (such as air, water, or any other liquid or solid matter).
Pressure waves are produced when an object vibrates, such as a ringing phone, and these waves are known as sound waves. The surrounding medium's particles are disturbed by the pressure wave, and those particles disturb the particles next to them, and so on.
Like ocean waves, the disturbance's pattern causes outward movement in all directions. Usually in all directions and with decreased intensity as it gets further away from the source, the wave transmits the sound energy through the medium.
Therefore, Sound waves are longitudinal waves that travel through a medium like air or water. When we think about sound, we often think about how loud it is (amplitude, or intensity) and its pitch (frequency).

Wilkins and Franklin studied the structure of DNA using X-rays, a technique to examine molecules, and helped Watson and Crick determined that the shape of the molecule was a double helix.
What are the functions of DNA?Deoxyribonucleic acid is a polymer composed of two polynucleotide chains that coil around each other to form a double helix. The polymer carries genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses.
DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins.
DNA is essential for inheritance, coding for proteins, and providing instructions for life and its processes. DNA dictates how a human or animal develops and reproduces, and eventually dies.

Explain why the human population must seek balance between the need for food and environmental protection
Answer: Because currently the type of human food and the way it is produced, damages the environment of our planet. And if this continues, we will reach an irreversible point where we will destroy the only planet we have to live on.
Explanation:
Humans need to eat a varied and balanced diet, so a correct diet must contain adequate amounts of proteins, lipids, carbohydrates, vitamins and minerals. In addition, it is necessary to take into account the need for drinking water. However, the modern diet is often unbalanced, unstructured and is often associated with an increasingly sedentary lifestyle.
Human activities to produce food are carried out through land clearing, tillage and the introduction of new plant and animal species, and their effects depend on the extent and frequency of exploitation. An example is the elimination of native vegetation or the passage of heavy machinery, in order to use these lands to raise farm animals that will eventually produce meat and milk for consumption but at the cost of damaging forests. Reducing the amount of forests and vegetation has severe consequences in terms of climate change and the further increase of torrential rains and floods. So, this is an example where increased production of one type of food produces severe damage to the environment. In addition, the main source of contamination is found in the wastewater from slaughterhouses, which includes feces and urine, blood, lint, laundering and residues of meat and fat from carcasses.
In some cases, population growth has led to intensified land use and increased productivity in areas already prepared for cultivation. In other cases, population growth has not been matched by increases in productivity, leading to an increase in land devoted to food production.
On the other hand, the high consumption of processed foods (candies, cookies, mayonnaise, etc.) is packaged in plastic containers that are highly pollutant. Therefore, moving away from a more natural food, makes us produce more garbage.
It is necessary to find ways to achieve a sustainable balance without giving up the fight against hunger and environmental protection. However, there are currently economic interests that influence the forms of production and the type of food the population eats. And the increase in the world's population means that arable land per inhabitant is constantly decreasing. The environmental impact that natural and human systems can tolerate has its limits.
There are also more and more farmers reducing the use of pesticides and fertilizers, but this production is limited in relation to total food production. There is evidence that these production strategies, in addition to being more environmentally beneficial, are economically viable for the market sectors they serve. However, most large-scale commercial producers find the intensive use of pesticides and mineral fertilizers economically profitable, and there has not been a general acceptance of environmentally friendly production technologies such as integrated pest management and integrated plant nutrition systems.
As a summary, currently the type of food we eat and the way we produce it, damages the environment of our planet. And if this continues, we will reach an irreversible point where we will destroy the only planet we have to live on.

Which amino acids do the following codons encode - UUC,
UCU, CUU?
a Phenylalanine, serine, leucine
b Serine, alanine, leucine
C Methionine, serine, leucine
d None of the above
Answer:
A A U C C
A AAA Lysine AUA ACA Threonine
A AAU Asparagine AUU ACU Threonine
A AAC Asparagine AUC ACC Threonine
The codon UUC encodes for the amino acid phenylalanine, the codon UCU encodes serine, and the codon CUU encodes leucine. So the correct answer is (a).
Organic substances known as amino acids have both amino and carboxylic acid functional groups. Proteins are made up of substances called amino acids. Proteins and amino acids are the components of life.
A collection of instructions called the genetic code governs how DNA is converted into proteins. Codons, which are three-nucleotide sequences, are the building blocks of the code. Codons each represent each individual amino acid.
The codons UUC, UCU, and CUU all code for the amino acid phenylalanine. The third nucleotide in the codon determines the amino acid that is encoded. The codons UUA and UUG has different nucleotide from phenylalanine in the third position and thus code for leucine. The codon UCG encode for Serine.
Therefore, option (a) is right.

which protects the dna of a virus
A pilus
B plasmid
C bacteriophage
D capsid
A capsid is a protein shell that protects the DNA of a virus. The correct answer is D) capsid.
What is a capsid ?A capsid is a protein shell that encases the genetic material (either DNA or RNA) of a virus. It is a protective layer that helps the virus survive in harsh environments and protects its genetic material from damage by environmental factors such as UV light, enzymes, and other harmful substances. Capsids can be composed of one or more types of proteins and can take different shapes and sizes depending on the type of virus.
In addition to the capsid, some viruses may also have other protective structures or mechanisms that help them survive in their host environment. For example, some viruses have a lipid envelope that surrounds their capsid, which helps them enter and exit host cells more easily. Others may have other protective layers, such as a protein coat, that help them resist immune system defenses.
It is worth noting that neither A) pilus nor B) plasmid nor C) bacteriophage protects the DNA of a virus. A pilus is a hair-like structure found on the surface of some bacteria that helps them attach to other cells or surfaces, while a plasmid is a small circular piece of DNA that is separate from the bacterial chromosome and may carry genes that confer antibiotic resistance or other advantageous traits.
Hence, Bacteriophages are viruses that infect and replicate within bacterial cells, but they do not protect the DNA of other viruses.

Why is the defense attempting to exclude OJ’s domestic Violence history from the court case?
Answer:
The celebrity of the defendant, the other major players, and the case itself had, and continues to have, society as a whole discussing domestic violence and the effectiveness of our laws that deal with this area of criminal law. Since the commission of the crimes in June of 1994, the Simpson' case brought to the forefront the issue of what role evidence of prior domestic violence should play in criminal prosecutions. In addition to the forensic evidence which the Los Angeles prosecutors relied upon to attempt to convict Mr. Simpson, the theory of the prosecution's case rested on the proposition that Mr. Simpson committed the murders against his former wife, Nicole Brown Simpson (hereinafter Ms. Brown), and her friend, Ronald Goldman, because of jealousy, obsession, and the need to dominate Ms. Brown. The prosecution's case rested entirely upon circumstantial evidence, and as such, the prosecutors sought to introduce evidence of Mr. Simpson's past abusive conduct toward Ms. Brown to establish the identity of the perpetrator and his motives to commit the brutal crimes. The prosecution argued that the history of domestic violence and prior threats were probative evidence of Mr. Simpson's motive, intent, plan, and identity as the killer. According to Los Angeles District Attorney Gil Garcetti, the trial judge's ruling on the admissibility of this evidence was the "most critical ruling" that the Court would make in the case The prior conduct which the prosecution wanted to introduce on its direct case included acts of physical beatings upon Ms. Brown by Mr. Simpson, some of which were documented by photographs showing Ms. Brown's injuries. Other incidents included an episode in which Mr. Simpson had thrown Ms. Brown out of a moving car; a 1989 assault for which Ms. Brown had been hospitalized due to her injuries; Mr. Simpson's 1989 no contest plea to spousal abuse for which he was ordered to undergo counseling and pay a fine; letters of apology for the abuse written by Mr. Simpson to Ms. Brown; Mr. Simpson's repeated threats to kill Ms. Brown; a 1993 recording of a "911" telephone call made by Ms. Brown to the police, during which the voice of Mr. Simpson was heard making threats and shouting obscenities at Ms. Brown; evidence that Mr. Simpson was stalking Ms. Brown, and that shortly before her death, Ms. Brown had made contact with a battered women's shelter help-line; and many other instances of actual and threatened violence committed by Mr. Simpson against Ms. Brown dating back to 1977. In January 1995, Judge Lance Ito, who presided over the murder trial, ruled that much of the domestic violence history would be admissible on the prosecution's direct case, including the 1993 "911" tape-recorded telephone call by Ms. Brown. The evidence was admitted to provide the jury with an appreciation of the "nature and quality" of the relationship between Mr. Simpson anji Ms. Brown, and to aid in establishing motive, intent, plan, and identity of the killer.
