Explain how the availability of resources in the environment is linked to exponential growth of a species
Answer: Exponential growth occurs when resources in the environment are abundantly available to a species.
Explanation: When a food source amount drops, so does the survival rate of the predator that eats that specific food source. When a food source grows too abundantly at too fast a rate, predators increase in numbers.

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.

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.
What process moves the water from the roots to the leaves
Answer:
The process is called transpiration stream. in plants transpiration stream is the uninterrupted stream of water and salutes which is taken up by the roots and transported via the xylem to the leaves where it evaporates into the air/apoplast- interface of the substomatal cavity. it is driven by capillary action and in some plants by root pressure.

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.

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).

Answer:
The answers are A and B.....
Clearly explain the role of mutations in evolution.
Answer:
Mutations are changes in DNA and changes in DNA affect all aspects of an organisms life. The first step to evolution is mutation since it creates new DNA sequences for certain genes. By doing so, is creates new allele. The allele is able to spread through reproduction. All genetic features were initially caused by mutations. Mutation is practically the only way in which a species can have a new variation and so, mutations are the raw material of evolution. Although only hereditary mutations cause evolution, mutations have a large impact on evolution.
