Explanation:
1. AMINO ACIDS are the basic building block of proteins; they contain a carboxyl group (-COOH) and an amino group (-NH 2) in their structure. 2. A CATALYST is any substance that accelerates a chemical reaction without being used up in the reaction. They do this by lowering the activation energy of the reaction. 3. Deoxyribose nucleic acid (DNA) is a complex molecule containing the genetic code. It carries all the genetic information of living organisms. 4. AN ENZYME is a protein molecule that is specialized to speed up a specific chemical reaction in biological systems. It is referred to as a biological catalyst because it speeds up a chemical reaction in living systems. 5. NUCLEIC ACID is a sequence of sugars, phosphates, and nitrogenous organic bases. A nucleic acid (DNA and RNA) is a polymer of nucleotides, which are composed of the three molecules mentioned above. A sequence of nucleotides forms a NUCLEIC ACID. 6. PROTEIN is a large, complex organic molecule consisting of a large number of amino acids linked together by peptide bonds. The amino acid building blocks are linked together in a condensation reaction and catalyzed by Peptidyl transferase enzyme. 7. Ribonucleic acid (RNA) is a type of nucleic acid that participates in the synthesis of proteins. RNA is of three types viz: mRNA, rRNA and tRNA. They all play a role in the process of protein synthesis. 8. A SUBSTRATE is a compound that is involved in a chemical reaction and is chemically changed by the reaction.

help meee,A study was carried out on the emission of N2O in a sewage treatment plant (ETE) in the metropolitan region of Rio de Janeiro.
of January. During the study period, this ETE received sewage from 470,000 inhabitants. One particularity observed is that in addition to receiving domestic sewage, this station received, during a certain period of the day,the material leached from a sanitary landfill, responsible for causing an increase in the load of organic matter in the ETE in study. Continuous measurements of dissolved oxygen concentration and N2O emission were carried out at this station for 3
hours, in the period prior to the entry of the material leached from the landfill and in the period immediately after the entry of this material.
1-Why, soon after the material from the landfill, the concentration of dissolved oxygen decreased;
2-Why is there a significant increase in the emission of N2O soon after the entry of the leached material from the landfill? What bacterial processes can contribute to the increase in the emission of this observed gas
in this experiment?
Answers
The emission of N2O from the landfill site is called denitrification and it is caused by the action of denitrifying bacteria.
What is dissolved oxygen?The term dissolved oxygen refers to the amount of oxygen that is present in a water body. Now, we know that the addition of organic matter into water requires oxygen to break it own thus the dissolved oxygen content will go down in response to the added organic load.

An atom charged -3 has atomic number 23 and atomic mass 32 what is the number of electrons of this atom
Answers
An atom charged -3 has the atomic number 23 and an atomic mass of 32, the number of electrons of this atom are 20.
What is an Atomic number?An atomic number may be defined as the number of a chemical element in the periodic table, in which the elements are positioned in order of expanding the number of protons in the epicenter known as the nucleus.
In this question, the number of electrons is 20, because the number of electrons in an atom is always equal to the atomic number of that atom, which is 23 here.
But, an atom charged -3, so, 23-3 = 20. If an atom is charged negative, the number of electrons is determined by subtracting it with an atomic number, while if it is charged positive, the number of electrons is determined by adding it with an atomic number.
Therefore, it is well described above.

the proportions of the nucleotides to be in the newly formed complementary strand?
Answers
Answer:
The proportions of nucleotides in the newly formed complimentary strand will be:
14% Thymine (T), 33% Adenine (A), 21% Guanine (G), 32% Cytosine (C).
Explanation:
In a double stranded DNA, the nucleotides of one strand binds with nucleotides of another strand through hydrogen bonds.
Adenine binds with thymine by two hydrogen bonds (A=T) and guanine binds with cytosine by three hydrogen bonds (G≡C).
So, the complimentary strand must have
thymine equal to the amount of adenine in template strand.adenine equal to the amount of thymine in template strand.guanine equal to the amount of cytosine in template strand.cytosine equal to the amount of guanine in template strand.An invasive species has been introduced to a pond, using up many resources and resulting in the decline of several pond species.The same invasive species is introduced into the ocean.

Two subgroups of a population separated by a river are rejoined when a drought causes the river to run dry. Assuming that speciation has not yet occurred, what is true about the two subgroups?
A. Speciation will speed up since there will be more competition
between the subgroups.
B. The likelihood that speciation will be completed will decrease.
C. The two subgroups will still be reproductively isolated and unable
to mate.
D. New traits that resulted from mutation will not flow between the
subgroups.
Answers
When separated subgroups of a population are rejoined due to drought, increased gene flow reduces reproductive isolation and lowers the likelihood of speciation. The correct answer to the question is B.
When two subgroups of a population are separated by a geographic barrier, such as a river, reproductive isolation occurs, which can lead to speciation over time. However, when a drought causes the river to run dry and the subgroups are rejoined, gene flow between the subgroups increases. This increased gene flow can reduce reproductive isolation and decrease the likelihood of speciation. Therefore, option B is correct. Option A is incorrect because increased competition between the subgroups does not necessarily speed up speciation. Option C is incorrect because when the subgroups are rejoined, they can interbreed and are no longer reproductively isolated. Option D is also incorrect because traits resulting from mutation can flow between the subgroups due to increased gene flow.For more questions on drought

You will write an argumentative essay to the “Bill and Melinda Gates Foundation” to convince them to support the use of genetically modified organisms in agricultural development and support your team in developing the transgenic strain, knowing that this organization can provide the needed funding for your project.
The word count of your essay should be between 300 and 750.
Your essay should include at least 10 keywords from table 2.
Your essay will discuss how the new strain of the genetically modified plant will contribute to eradicating disease by using appropriate scientific methods that take into consideration any possible adverse health effects and environmental concerns (such as new potential allergies, herbicide resistant weeds, and biodiversity issues for replacing other strains). It will also discuss why community acceptance of the new strain is important as a sustainable long-term solution as opposed to supplements or other food additives.
The purpose of your essay is to establish a stance on the urgency of the new strain issue by providing reasons and supporting evidence. When you’re writing a persuasive essay, you need more than just an opinion to make your voice heard. Even the strongest stance won’t be compelling if it’s not structured properly and reinforced with solid reasoning and evidence. Your essay needs to be well written and should include the following 4 elements:
1. Introductory paragraph:
The first paragraph of your essay should outline the topic, provide background information necessary to understand your argument, outline the evidence you will present and states your thesis.
2. The thesis statement:
This part of your essay is a concise, one-sentence summary of your main point and claim.
3. Body paragraph:
You will explain the reasons why you support your thesis. You can discuss more than one idea or piece of evidence that clearly and concisely explain why the reader should agree with your position.
This is where you will back up your claims with examples, research, statistics, studies, and scientific evidence based on your knowledge in genetics and your answers in the graphic organizer.
Address opposing points of view and disprove them or explain why you disagree with them. Presenting facts and considering the topic from every angle adds credibility and will help you gain the reader’s trust.
4. Conclusion:
One paragraph that restates your thesis and summarizes all of the arguments made in your body paragraphs. Rather than introducing new facts or more arguments, a good conclusion will appeal to a reader’s emotions. In some cases, writers will use a personal anecdote explaining how the topic personally affects them.

Genetically modified organisms can help to alleviate hunger around the world by increasing crop yields.
What are Genetically modified organisms?Genetically modified organisms are organisms whose genetic material (DNA) has been altered in the laboratory by using genetic engineering.
Genetically modified crops can be resistant to different types of biotic and abiotic stressful conditions and thus increase crop yield.
Supporting evidence regarding the use of GMOs is based on empirical statistics about how these food helped to alleviate global hunger, especially in developing countries.
An essay about GMOs should ideally include information on genetic engineering techniques used in transgenesis.
Transgenesis refers to the genetic engineering techniques aimed at developing organisms carrying genes of others species. These techniques include, among others, the use of the CRISPR-Cas9 genome editing system, DNA recombinant strategies and vector expression constructs (e.g., viral recombinant vectors).
A thesis statement is a well-sustained question that can be tested (either confirmed or rejected) by information obtained using the scientific method.
GMOs have been shown to the safe since empirical scientific evidence revealed that genetically modified crops such as Bt maize do not cause allergies or diseases in human beings.
Moreover, GMOs can help to alleviate hunger around the world by increasing crop yields.
In conclusion, it is possible to state that GMOs might be beneficial when they are approved and released by proper governmental agencies such as the US Federal agency of Food and Drug Administration (FDA).

What is a river system?
A river system is a term used to describe the broader networks of streams, lakes, and rivers that are tributaries and distributaries of a larger river. For instance, the Mississippi River system includes the Ohio, Red, and Missouri rivers, all of which drain into the Mississippi River. Due to its interconnectedness, the condition of one river may have an effect on the health of the other rivers in the same river system. A river system can also include other types of terrain, such as the wetlands and flood plains that are affected by a major river and its tributaries and distributaries. The majority of the time, rivers have a primary source, such as snowmelt from a mountain that cascades into a number of streams, which eventually merge to form a river that empties into a much bigger river. This is an illustration of a river network. River systems are ecosystems from an environmental perspective, and if even one component of the system is contaminated or destroyed, it may have a severe impact on things like water quality and the health of plants and animals. For instance, the effects of high pollution levels or prolonged drought near a river's source will be felt throughout the rivers and lands that make up the river system.
