Explanation:
Concerns from Biotechnology
The use of biotechnology has raised a number of ethical, legal, and social issues. Here are just a few:
Who owns genetically modified organisms such as bacteria? Can such organisms be patented like inventions?Are genetically modified foods safe to eat? Might they have unknown harmful effects on the people who consume them?Are genetically engineered crops safe for the environment? Might they harm other organisms or even entire ecosystems?Who controls a person’s genetic information? What safeguards ensure that the information is kept private?How far should we go to ensure that children are free of mutations? Should a pregnancy be ended if the fetus has a mutation for a serious genetic disorder?
The ELSI issues are important and require to be maintained in order to maintain bioethics and examine various impacts of science and technology on the society.
What are ELSI issues?ELSI stands for Ethical, Legal, and Social Issues. It is a widely used acronym in the bioethics literature which encompasses a broad range of research work which mainly examines the various impacts of science and technology on the society.
The ultimate mission of the ELSI Research Program is to support the research and education activities which include promotion of genetic privacy and fair use of genetic information, encouraging the responsible integration of new genetic information and technologies into clinical and non-clinical settings, and to ensure that the genetic research is being conducted in ethical way.

A. point C
B. point B
C. point A
D. point D
Answer:
The correct answer is option D. point D.
Explanation:
Carrying capacity is characterized as the maximum populace size that a domain can continue inconclusively. For most species, there are four factors that factor into figuring the carrying capacity of an individual population: food accessibility, water resources, habitat, and ecological conditions.
In a graph representation of population size in a time period increases until it reaches carrying capacity, carrying capacity is representing in the graph where the increase in curve becomes stable and makes a plateau.
Thus, the correct answer is option D. point D.

An important example of a "positive feedback loop" in the polar climate system is:
a.Scientists in remote places check on each others instruments.
b.Warming ocean water opens new areas for marine species.
c.Warmer winters cause more plant growth, providing more food.
d.Sea ice melt opens more ocean to sunlight, causing more melt.
Answer: D
Explanation:
A positive feedback loop occurs in nature when the product of a reaction leads to an increase in that reaction.
In choice D melting of sea ice opens more ocean to sunlight which causes more ice to melt which demonstrated a positive feedback loop.
The significant example of a positive feedback loop in the climate system i.e. polar should be at the time when the ice of the sea should be melt that there should be more ocean that results in more melting.
The following information related to the positive feedback loop is:
If the direction varies so it should result in an extra change in a similar direction.Like if we take an example that if there is an increase in the substance concentration so it results in the feedback that generated the continued increase in the concentration.Therefore we can conclude that option d is correct.
All other options seem incorrect.

What is the subject of a memoir? A. an experience or period in the author’s life B. a significant historical event C. a fictional adventure story D. an analysis of a certain topic
A. An experience or period in the author’s life.
Explanation:
A memoir is a story about an experience in someones life, but it has to be factual. A memoir can not be based on fiction, it has to be real and nonfictional.
Memoirs are usually told in first person, as it is recounting the occurrences that happened in ones life. It is different from an autobiography, as autobiographies usually focus on the whole lifespan of a person, while a memoir focuses on one topic or event that happened.
Memoirs also usually focus on personal growth throughout the writing, are truthful and keep track of the persons goals and influences.

Identify the type of mutation that occurred in the sequence above and evaluate the significance of these changes. (Will it have any problems in protein synthesis?)
Hint: 1st determine if it was copied to mRNA correctly. When you find the error, that is the mutation. 2nd use the chart if a different amino acid is created, this will determine if it will affect protein synthesis.
Answer:
See the answer below.
Explanation:
The correct mRNA sequence from the DNA according to the base pairing rule should be:
AAU GCG UUG ACC GAU UAA
Instead of:
AAU GCG UGA CCG AUU AAC
This thus means that some of the nucleotide bases have been wrongly substituted.
The most important change is the codon 'UUG' becoming 'UGA', while the former codes for the amino acid leucine, the latter represents a stop codon. A stop codon will result in a non-functional or defective protein.
Hence, the type of mutation is nonsense mutation which results in a sudden cessation of protein synthesis as a result of a codon being prematurely changed to a stop codon.
The significance of this kind of mutation is that a defective on non-functional protein will result which will have a serious phenotypic implication in organisms.
Genetic drift and natural selection can both be mechanisms of evolution. However, they are very different mechanisms. Explain how genetic drift is different from natural selectio
Answer:
Explanation:
Natural selection is the survival of individual organism due to the difference in phenotype. It serves as a basic for evolution as the different heritable characteristics in an individual is due to natural selection. Natural selection acts on the phenotype of the individual which is the visual observance while Genetic drift is the change in frequency of an allele that already exist in a population. This could lead to the allele being selected against and if very small can be lost with time.
Describe step by step, with your own words, the process of replication of a double strand of DNA.
Answer:
replication. DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell.

which is not an example of inorganic fertilizer? A.nitrogen fertilizer B.phosphorus fertilizer C. Livestock waste
Answer:
Livestock waste
Explanation:
Fertilizers supplement the soil with macronutrients needed in large amounts: nitrogen, phosphorous and potassium. However, organic and inorganic fertilizers do so via different materials. Organic fertilizers contain only plant- or animal-based materials that are either a byproduct or end product of naturally occurring processes, such as manures, leaves, and compost.
Inorganic fertilizer, also referred to as synthetic fertilizer, is manufactured artificially and contains minerals or synthetic chemicals. For example, synthetic nitrogen fertilizers are typically made from petroleum or natural gas. Phosphorus, potassium and other trace elements in inorganic fertilizers are often mined from the earth. Balanced inorganic fertilizers, high in all three macronutrients, commonly include products like ammonium nitrate, ammonium sulfate, potassium chloride (potash), triple superphosphate, and magnesium sulfate (Epsom salts).
