Why scientists concluded that the instructions for species characteristics were carried in dna

Answers

Answer:

Explanation: Deoxyribonucleic acid is said to contain instructions for species characteristics because it carries the information that characterizes an individual.

DNA is made up of Nitrogenous bases that are unique codes specified by an individual and no two people have the same DNA.

Genes are genetic information or instruction that specify an individual. it is located in the chromosome in the nucleus. DNA contains a gene that helps to make molecules called proteins. It is the basis of all inheritance and the expression of the gene is what produces the phenotype that is visible.

Several lines of evidence from various fields of biology and genetics have led scientists to the conclusion that the instructions for species characteristics are carried in DNA.

To begin with, it has been discovered that the offspring of living organisms resemble their parents in many ways. This is true for traits like eye color, hair color, height, and many others. This observation implies that some kind of information or instructions must be passed down from generation to generation.

Second, research into inheritance patterns in plants and animals has revealed that certain traits are passed down in a predictable manner from generation to generation. This resulted in the development of Gregor Mendel's laws of inheritance in the nineteenth century, which established that genetic traits are carried on discrete units known as genes.

Third, using advanced microscopic techniques, scientists discovered that the nucleus of a cell, which contains the genetic material, is made up of thread-like structures known as chromosomes. Further research revealed that chromosomes were made of a chemical substance known as DNA (deoxyribonucleic acid).

Protein synthesis in eukaryotes is similar to the process in prokaryotes in that both eukaryotes and prokaryotesA) have intronsB) use codons to determine polypeptide sequencesC) have exonsD) use methionine as the "start" amino acidE) require snRNPS

Answers

The correct option is B ; Use codons to determine polypeptide sequences , DNA (short for deoxyribonucleic acid) is a long, double-stranded molecule that contains the genetic instructions for the development, function, growth, and reproduction of all living organisms.

It is made up of four types of nucleotide building blocks: adenine (A), guanine (G), cytosine (C), and thymine (T). The specific sequence of these nucleotides in DNA carries the genetic code, which determines the unique traits of an organism. DNA is found in the nucleus of eukaryotic cells and in the cytoplasm of prokaryotic cells. It is also responsible for the process of DNA replication, where the genetic material is duplicated before cell division, and for the transmission of genetic information from parent to offspring.

Protein synthesis, also known as translation, is a fundamental biological process that is responsible for the production of proteins from the genetic information contained within the DNA. While the overall process of protein synthesis is similar in eukaryotes and prokaryotes, there are some key differences between the two.

One major similarity is that both eukaryotes and prokaryotes use ribosomes, which are the molecular machines responsible for synthesizing proteins, to carry out protein synthesis. In both cases, the process involves a series of steps including initiation, elongation, and termination, where the ribosome reads the genetic code and assembles a chain of amino acids to form a protein.

Hence, both involve the use of ribosomes to translate the mRNA into a sequence of amino acids to form the protein.

Answers

The list contains only omega-3 fatty acids is  EPA, DHA, alpha-linolenic acid.

What is fatty acids?

Fatty acids are organic molecules made up of a chain of carbon atoms with hydrogen atoms attached to them. They are essential components of fats and oils, which are vital for our health and nutrition. There are three types of fatty acids - saturated, monounsaturated, and polyunsaturated. Saturated fatty acids are typically solid at room temperature and are mostly found in animal-based foods such as meat, butter, and cheese. Monounsaturated and polyunsaturated fatty acids, on the other hand, are liquid at room temperature and are mostly found in plant-based foods like nuts, seeds, and vegetable oils.

EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) are both omega-3 fatty acids that are found in fish and seafood. Alpha-linolenic acid is also an omega-3 fatty acid, but it is found in plant-based sources like flaxseed, chia seeds, and walnuts.

Linoleic acid and arachidonic acid are both omega-6 fatty acids, which are also important for our health but are not part of the omega-3 family. Therefore, the only list that contains exclusively omega-3 fatty acids is B, EPA, DHA, and alpha-linolenic acid.

B.Fewer binding events occur on BAZ2B as the experiment progresses
C.Less H3 is present in each subsequent injection as the titration progresses.
D.Negative cooperativity exhibited by BAZ2B causes binding to decrease as H3 is added.

Answers

The size of the ITC peaks decrease over the course of each experiment less H3 is present in each subsequent injection as the titration progresses.

ITC stands for Isothermal Titration Calorimetry, which is a technique used to measure the thermodynamic properties of a binding reaction between two molecules. In an ITC experiment, one molecule (the ligand) is titrated into a solution of the other molecule (the receptor) while the heat released or absorbed by the reaction is measured.

If the ITC peaks decrease during the titration, this suggests that the binding affinity between the ligand and receptor is decreasing. Specifically, the peak areas represent the amount of heat that is released or absorbed during each injection of the ligand into the receptor solution. A decrease in the peak areas therefore indicates that less heat is being generated by the binding reaction with each subsequent injection, which implies a weaker binding interaction.

There are several reasons why the binding affinity between two molecules might decrease during an ITC titration. For example, the binding site on the receptor molecule may become saturated with ligand molecules, leading to reduced binding affinity for additional ligand.

Hence, the correct option is C.

Answers

In convection, heat transfer occurs due to the movement of gas and liquid molecules. Here the heat transfer is because of convection in all the given cases.

How can sunlight detect heat transfer by radiation?

Flow is a term that refers to the movement of heated water or air. Heat is transferred by electromagnetic waves or radiation. The electromagnetic waves that travel from the sun to the earth radiate mostly infrared light (not so much visible light), and they warm your body when you're near the sun.

Why is convection used as an example when boiling water?

Heat transfer from the convection burner causes the water heated at the bottom of the pot to boil. Hot water rises and is fed by cold water, creating a circular motion.

How does conduction carry heat?

Heat conduction occurs when two objects with different surface temperatures come into contact. At the point of contact, energy is transferred directly from the material of the warmer component to the material of the cooler component.

For an enzyme that follows Michaelis-Menten kinetics, KM is equal to the [S] at one-half Vmax. (option c)

Michaelis-Menten kinetics is a mathematical model that describes the behavior of enzymes in catalyzing reactions. KM is the Michaelis constant, which is a measure of an enzyme's affinity for its substrate. It represents the substrate concentration at which the enzyme reaction rate is half of its maximum velocity (Vmax).

The value of KM is unique to each enzyme and reflects the strength of the enzyme-substrate binding. When the substrate concentration is less than KM, the reaction rate is proportional to the substrate concentration, while when the substrate concentration is greater than KM, the reaction rate reaches a plateau at Vmax.

Therefore, determining the value of KM is important in understanding enzyme kinetics and can provide insight into the efficiency of enzyme reactions and potential points of regulation in metabolic pathways.

The architecture and activities of rose and heart cells are distinct and are tailored to the jobs that they play in the body. Rose cells perform photosynthesis and sustain the structure of the plant, whereas heart cells are responsible for pumping blood.

As per the question given,  

Two very distinct sorts of cells—heart cells and rose cells—serve various purposes in their respective animals. Animals' and humans' hearts include heart cells, which are in charge of pumping blood throughout the body. In contrast, rose cells are plant cells that make up the tissues of roses and are responsible for photosynthesis as well as sustaining the structure of the plant.

The position of heart cells vs rose cells is one of the most evident distinctions. Heart tissues, which are a component of the circulatory system, include heart cells, whereas the tissues of roses, which are a component of the plant's structure, contain rose cells.

Their organisational structure is another key distinction. Heart cells are specialist muscle cells with a specific shape that enables them to pump blood as they contract and relax. They are structured in a sophisticated network of fibres to enable synchronised contraction and relaxation, and they feature intercalated discs that allow electrical impulses to go between cells.

What are your thoughts about how China was

Answers

Answered By Unish ©

Verified Answer ✅

Explanation:

China used to be the world's largest importer of recyclable materials, taking in around 70% of the world's plastic waste alone. This was because other countries found it cheaper to send their waste to China rather than recycling it themselves. However, China's recycling practices have caused a number of problems.

One major issue is that China has been overwhelmed by the sheer amount of waste it has been receiving, resulting in many landfills and processing facilities becoming filled to capacity. This has led to environmental problems, such as water and air pollution, as well as health risks to workers in the recycling industry.

Another problem is that not all of the waste that

was being sent to China was actually recyclable. Contaminated materials, such as dirty or mixed plastics, were often sent, which made it difficult for China to effectively process the waste. This, in turn, led to a build-up of waste in the country, as well as an increase in illegal dumping.

In response to these issues, China implemented stricter regulations on the importation of waste, which has significantly reduced the amount of waste it is now accepting. As a result, other countries have had to find alternative ways to deal with their waste, including increasing their own recycling capacity or finding new export destinations.

Overall, China's recycling practices have highlighted the need for more responsible waste management practices globally and the development of more sustainable and circular economies.

which of the following statements about evolution is true? group of answer choices species are the result of accumulations of changes within a lineage. organisms are constantly striving to be better. evolution is about progress and improving on life forms from the past. it is attributed to herbert spencer. humans are better, more evolved chimpanzees.

Answers

The following statement about evolution is true: species are the result of accumulations of changes within a lineage.

What is biological evolution?

Biological evolution is the process by which species of organisms change over time, through the gradual accumulation of genetic variations and the natural selection of those variations that are advantageous for survival and reproduction. It is driven by factors such as mutation, genetic drift, gene flow, and natural selection, and occurs over long periods of time, sometimes millions of years. Biological evolution explains the diversity of life on Earth, as well as the relationships between different species and their shared ancestry. It is a fundamental concept in biology and is supported by a large body of scientific evidence from fields such as genetics, paleontology, and comparative anatomy.

Here,

Evolution is a process that occurs over long periods of time, driven by genetic variation, natural selection, and other factors. Species gradually change over time as advantageous traits become more common and less advantageous traits are selected against. Evolution is not about progress or improvement, but rather about adaptation to changing environments and survival in the face of competition and other challenges. It is a scientific concept that has been studied and refined over many years, and is not attributed solely to any one individual such as Herbert Spencer. Finally, humans and chimpanzees are both evolved species, but neither is considered "better" or more evolved than the other.
