How has dna technology led to advancements in forensics medicine and agriculture?
Answer:
DNA technology is very beneficial in the criminal and civil justice system, methods such as fingerprinting are used very often when trying to find a person behind a crime. This technology has also improved our use of medicine. One way is breeding plants to create more options of curing diseases by using adding nutrients and minerals. Lastly, DNA is used to grow crops that have a lot more nutrients and minerals that are added from other plants.
Explanation:
Characterization, or ''typing," of deoxyribonucleic acid (DNA) for purposes of criminal investigation can be thought of as an extension of the forensic typing of blood that has been common for more than 50 years; it is actually an extension from the typing of proteins that are coded for by DNA to the typing of DNA itself. Genetically determined variation in proteins is the basis of blood groups, tissue types, and serum protein types. Developments in molecular genetics have made it possible to study the person-to-person differences in parts of DNA that are not involved in coding for proteins, and it is primarily these differences that are used in forensic applications of DNA typing to personal identification. DNA typing can be a powerful adjunct to forensic science. The method was first used in casework in 1985 in the United Kingdom and first used in the United States by commercial laboratories in late 1986 and by the Federal Bureau of Investigation (FBI) in 1988.
DNA typing has great potential benefits for criminal and civil justice; however, because of the possibilities for its misuse or abuse, important questions have been raised about reliability, validity, and confidentiality. By the summer of 1989, the scientific, legal, and forensic communities were calling for an examination of the issues by the National Research Council of the National Academy of Sciences. As a response, the Committee on DNA Technology in Forensic Science was formed; its first meeting was held in January 1990. The committee was to address the general applicability and appropriateness of the use of DNA technology in forensic science, the need to develop standards for data collection and analysis, aspects of the
technology, management of DNA typing data, and legal, societal, and ethical issues surrounding DNA typing. The techniques of DNA typing are fruits of the revolution in molecular biology that is yielding an explosion of information about human genetics. The highly personal and sensitive information that can be generated by DNA typing requires strict confidentiality and careful attention to the security of data.

Explain how scientists use geologic time to determine the age of landforms. (3 points)
Answer:
I will!
Explanation:
to determine the related age of different rocks geologists start with the assumption that unless something has happened in the sequence of sedimentary rock layers the newer Rock layers will be on top of the older ones this is called the rule of superposition with absolute age dating you get a real age and actual years
Answer:
Geologic time uses the layers of rock to describe the relationships of events and their sequence in chronological order over the history of Earth. The layering is a result of the buildup of tiny bits of rock, sediment, or lava cooling at the surface over many years. Think of it like a stack of pancakes—the bottom layer is the one that was placed first and therefore is the oldest. The sediments that create the layers of Earth are stacked one on top of the other.

A common misconception is that proteins are a good source of energy. Explain which types of foods are the best energy sources and how this relates to the amount of ATP made by your cell.
Answer:
Carbohydrates.
Explanation:
It is carbohydrates because they are the good source of energy . When carbohydrates are consumed it's digestion starts from the mouth, from chewing and it mixes with saliva from the salivary gland. As it is broken down the chemical energy unlock in it is released into the body which is absorbed by the cells for cellular metabolic activities. They turns into energy as soon as they are ingested and they energy powers the brain and the whole body.
Examples of carbohydrates are wheat, whole grains, rice, bread e.t.c.

How do cell differentiation and cell division work together?
Answer:
After mitosis is over, each of the daughter cells continues its separate life.
Explanation:
One or both can be started or continued through differentiation, ie. processes that give different cells special structures and functions. A cell destined to become a nerve cell moves in one way of differentiation, and a cell destined to be a muscle cell moves in another.
A variation of this mechanism involves a special type of cell called a stem cell. The stem cell divides by mitosis, whereby one daughter cell remains the stem cell and continues to divide again and again, while the other difference in certain cell peaks is determined in the tissues.
Why did the movement of plants to land lead to adaptive radiation?
Answer: Adaptive radiation refers to the ability of living organisms to evolve rapidly from an ancestral forms into variety of other forms especially when the organisms move into a new environment that has abundant resources. The resources, which are present abundantly in the environment allow the living organisms to spread out in the environment and to find different habitats in the environments that favour their survival.In the question given above, adaptive radiation allows plants to fill different habitats (niches) that are found on land and to spread out rapidly.

What happens is substrate and enzyme is torn
Answer:If the enzyme changes shape, the active site may no longer bind to the appropriate substrate and the rate of reaction will decrease. Dramatic changes to the temperature and pH will eventually cause enzymes to denature.
Explanation:
A student carried out an investigation into the effect of temperature on the rate of an
enzyme-catalysed reaction.
At each temperature, the substrate concentration was measured after 10 minutes. All the other
variables were kept constant.
Which graph shows the effect of increasing temperature on the substrate concentration after
10 minutes?
Pls explain
Answer:
First graph.
Explanation:
If further increase in temperature occurs, it leads to decrease the substrate concentration because with very high temperature the enzyme is unable to perform its function. If the temperature is in optimum range, the enzyme produces more substrate due to favorable environment while on the other hand, if the temperature is below or above the optimum range so the enzyme can't perform its function properly and the substrate produce in small concentration.
why do vertebrates come from under chordates ?
Answer:
As chordates, vertebrates have the same common features: a notochord, a dorsal hollow nerve cord, pharyngeal slits, and a post tail. Vertebrates are further differentiated from chordates by their vertebral column, which forms when their notochord develops into the column of bony vertebrae separated by discs.

Use the diagram below to answer the following questions for 1 point each- explain the role of DNA in protein synthesis
Answer:
Regarding protein synthesis:
The role of DNA in protein synthesis is to contain the genetic information necessary for a specific protein to be manufactured, by transcribing it into mRNA.The role of mRNA in protein synthesis is to conduct the sequence of nitrogenous bases, organized in triplets or codons, to the ribosome for translation and initiation of synthesis.The processes of transcription and translation occur in the cell nucleus and cytoplasm, respectively.Explanation:
DNA is a molecule that contains the genetic information of an individual in a specific sequence of nitrogenous bases that are part of its structure. The process of transcription occurs in the cell nucleus and consists of the synthesis of a single-stranded mRNA molecule from one of the DNA strands.
The role of DNA in protein synthesis in the transcription of genetic information into mRNA.
Molecule of mRNA is that carries the sequence of nitrogenous bases that make up the genetic code, i.e., sequences of triplets or codons that encode the start of protein synthesis, the amount, type and order of amino acids of a protein, and the stop of synthesis.
The translation process —which occurs in the cytoplasm— is performed when the ribosomes read the genetic code and begins the union of amino acids into polypeptide chains. The role of mRNA in protein synthesis is then to drive the genetic code into the ribosome for translation.

During fission, two new, lighter nuclei are formed and fission energy is released, which is up to 20 times higher than the energy released in alpha, beta, and gamma decay (compared to chemical reactions, fission energy is a million times higher).
By breaking the nucleus of the atom, a huge amount of heat is released.
Jasmine is a healthy girl who is playing outside. Her internal body temperature rises to 38 degrees Celsius, which is above normal. How does her body most likely respond to help her return to homeostasis?
Answer:
See the answer below
Explanation:
Jasmine's body would help her return to homeostasis by using the negative feedback loop.
The negative feedback loop works to negate the process or processes that lead to the body's setpoint being breached. The setpoint refers to the normal range of operation of body processes such as temperature, pressure, etc.
The skin of Jasmine acts as a sensor and sends information to the control center, the brain. The brain reads the temperature data, finds out that the setpoint has been exceeded, and sends information to the effectors to initiate processes that will return Jasmine's body temperature to normal.
One of the effectors, the blood vessels that supply blood to the skin becomes dilated. Consequently, more blood is supplied to the skin and more heat is lost from the skin due to radiation - blood being a conductor of heat in the body. Another effector, the sweat glands, release sweat to the skin. The evaporation of sweat from the surface of the skin causes the body to cool down. These processes work synergistically to return the body temperature of Jasmine back to homeostasis.

By Sweating
