Which method of collecting data would provide the most accurate?
Takeaways. Quantitative research produces the most accurate and meaningful insights for analysis. Surveys are a common form of quantitative data collection and can be created and completed online, making them a convenient and accessible choice.
What does natural selection produce changes most quickly in?
Natural selection produces changes most quickly in species with short reproductive cycles. Since natural selection depends on the changes observable in successive generations within a species, in organisms with short reproductive cycles the changes promoted by natural selection could be observed most quickly.
Which structure regulates water loss and gas exchange?
Stomata are tiny holes found in the underside of leaves. They control water loss and gas exchange by opening and closing. They allow water vapour and oxygen out of the leaf and carbon dioxide into the leaf.
What is natural selection best described as?
Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. Individuals with adaptive traits—traits that give them some advantage—are more likely to survive and reproduce.
Which statement best explains why the replacement pets might not look or act like the original?
Which statement best explains why the replacement pets that are produced in this way might not look or act like the original? The new animal must get the DNA from two different parents, not just one cell. Mutations could occur that change the cloned animal into a completely different species.
What phrase does not describe cells cloned from a carrot?
Notes: Using gene splicing, recombinant DNA is created and inserted into bacteria. Which phrase does not describe cells cloned from a carrot? They have the same DNA codes.
Which statement is accurate description of genes?
Answer: An accurate description of genes is that genes are made of DNA and code for proteins. Explanation: Genes are the molecules responsible for containing the genetic information that determines specific characteristics or features of an individual.
Which statement is correct concerning hereditary information?
The correct answer is number one. A chromosome is composed of many genes. A chromosome is referred to as a DNA molecule in an organism’s body, which consists of genetic materials.
Do genes code for proteins?
A gene is the section of DNA required to produce one protein. Genes are typically hundreds or thousands of base pairs in length because they code for proteins made of hundreds or thousands of amino acids. Most genes contain the information needed to make functional molecules called proteins.
Which molecules are needed to cut and copy segments of DNA?
Carbohydrates are molecules from which our bodies derive energy in the form of ATP. Biological catalysts, or enzymes help our body speed up and perform all of the reactions that need to be done such as cutting and copying DNA. Therefore, choice (4) is the correct answer choice.
Which two enzymes are needed to cut and copy segments of DNA?
The discovery of enzymes that could cut and paste DNA made genetic engineering possible. Restriction enzymes, found naturally in bacteria, can be used to cut DNA fragments at specific sequences, while another enzyme, DNA ligase, can attach or rejoin DNA fragments with complementary ends.
What statement best describes a human chromosome?
Four different segments of a DNA molecule are represented below. Which statement best describes a human chromosome? It contains genes that may code for the production of enzymes.
Which statement best explains how the genetic code is universal?
The genetic code is said to be universal because all known living organisms use the same genetic code to encode their genetic information. This means that a DNA sequence codes for the same proteins in several different species. For example, codon AUG encodes the amino acid METHIONINE in every living organism.
Which best describes something that occurs during translation?
In translation, messenger RNA (mRNA) is decoded in the ribosome decoding center to produce a specific amino acid chain, or polypeptide, describes something that occurs during translation. This answer has been confirmed as correct and helpful.
What is the last step of transcription?
Termination is the ending of transcription, and occurs when RNA polymerase crosses a stop (termination) sequence in the gene. The mRNA strand is complete, and it detaches from DNA.
